One of the most prevalent clean and sustainable forms of energy produced worldwide is the power created from wind runoff. Wind turbines ought to be installed in areas with favorable circumstances to transform mechanical wind energy into electricity. Finding appropriate ways to predict the energy produced by a wind farm using the Weibull distribution is the main goal of this work. Theoretical techniques have been applied to calculate Weibull selected characteristics using experimental data gathered at the campus of Universidade Federal de Mato Grosso do Sul (UFMS) in Brazil. These data were gathered 10 meters above the surface. The effectiveness of four statistical techniques that are frequently used in the energy industry are compared: the standard energy factor method; the least squares regression method; the moment method; and the mean standard deviation method in estimating Weibull parameters. The root mean square error, Chi-square error, Kolmogorov-Smirnov test, and coefficient of determination are used to contrast the statistical methodologies. The results demonstrated that the least squares regression approach performs less well than other methods. The standard energy factor approach, the moment method, and the mean standard deviation method are the most effective techniques when modifying Weibull distribution curves for the assessment of wind speed data. The data analysis confirms that these three strategies are fully applicable if the wind speed distribution closely matches the Weibull distribution.

Temperature is a physical characteristic that is frequently encountered in daily life. It is linked to feelings of heat and cold. A thermometer is a device that measures the temperature in a specific place. There are many different types of thermometers available today, including mercury- or alcohol-based liquid thermometers, dial thermometers, infrared thermometers, electronic thermometers, etc. Each thermometer uses its own method to measure the temperature. Owing to its temperature sensors and recording mechanism, the developed experimental device (D.M.S.T. 1.0) enables the measurement and storage of temperature readings for a duration ranging from a few hours to several days. An accurate temperature reading in any medium (liquid, solid, or gas) can be taken using the newly created instrument at predetermined intervals (one second, one minute, one hour, etc.). Additionally, it has a graphical user interface that enables the data to be evaluated according to its intended usage. The new device is mainly composed of an Arduino Nano board, temperature sensors, a memory card, and connecting cables. After assessing the acquisition system's metrological quality, it has been used in the areas of building [1,2], renewable energy equipment [3,4], etc.

This paper presents a review of our previous work on the PV performance study. The aim of this study is to adapt the IEC 61724 standard [1] for the performance study of a Ain Skhouna (Saida, Algeria) PV plant for a period of one month. Likewise, the IEC 61724 standard application for the performance study for two PV power plants in Algeria (Adrar and Ain Skhouna) with different climates And, finely, the effect of ambient temperature on total losses, system efficiency, and performance ratio of the two PV power plants was studied. The International Energy Agency (IEA) has defined performance parameters that are detailed in IEC 61724 [1] in order to analyze the performance of any PV power plant. These variables provide data on the system's capacity to produce energy, its use of solar energy resources, and the overall impact of system losses [2,3]. These indicators include the energy generated by the PV array system (Edc), the energy output or energy fed to the utility grid (Eac), the reference yield (Yr), the array yield (Ya), the final yield (Yf), the performance ratio (PR), the system losses (LS), the capture losses (LC), system efficiency (ηsys), PV efficiency (ηPV), and inverter efficiency (ηinv). Two photovoltaic power plants are taken into consideration in this study: the Adrar PV power plant and the Ain Skhouna (Saida) PV power plant. These power plants are situated in two different climates: semi-arid for Saida and hot dry desert (hyper-arid) for the Adrar region. A data logger is installed in each of the two PV power plants to track and record the output of DC power from solar modules, AC power from inverters, and weather data. These data sets are captured every 15 minutes. All the results noted in this study were obtained according to the performance parameters specified by the International Energy Agency (IEA. Two different types of data are used: the data from the complete Ain Skhouna data for the year 2018[3], and the complete Adrar data for the year 2018[4].

Even for a limited period of time, weather conditions including solar radiation, temperature, wind, UV intensity, humidity, and precipitation have an effect on the degradation and efficiency of PV panels. As a result, these are the primary variables that impact the lifetime and durability of a photovoltaic system. Thus, increasing the efficiency of PV modules requires overcoming the critical problem of degradation. The current study aims to examine the deterioration of a poly-crystalline silicon photovoltaic panel that was exposed to outside conditions for four years in Biskra’s arid climate (Algerian town). To assess the performance of the tested PV module, two characterization techniques—I-V and P-V characterization as well as visual inspection—have been applied. Under normal conditions, a new model for determining the five criteria (a, Rs, Rp, I0, and Iph) has been developed using curve-fitting method. It was adapted for panels with and without degradation. By estimating how those parameters degrade, a new technique for identifying damaged panels has been created. The results highlight the dominance of the EVA degradation mode, which has a significant effect on the degradation rates of Rs (54.27%), Rp (−62.68%), and Iph (77.45%), as well as the evolution of the I-V and P-V curves.

The study explores the impact of surface orientation and tilt on incident solar irradiation. It was conducted in M'Sila, an Algerian province, from February to June. A number of experiments were carried out using an experimental setup consisting of a heliometer and a slant changer, which allowed for the variation of the tilt angle. Nineteen tilt angles ranging from 0° to 90° were investigated for the four main directions: North, South, East, and West. The obtained outcomes were statistically analyzed. At east and south orientations, incident solar irradiance rose as a function of tilt angle, reaching a maximum at the optimal angle, and then gradually decreased. Generally, the incident solar irradiance decreased as the tilt angle increased in the case of west and north orientations. The tilt angle of the exposed surface as well as the sun's elevation in the sky affected the amount of intercepted energy significantly at each orientation (p<0.05). When the sun was low in the sky, the south orientation was most preferred for an inclination greater than or equal to 25°. The north-facing surfaces with steep slopes (β³ 55°) received the least amount of solar radiation. These results hold great importance, particularly in the building sector, as they can be utilized to achieve energy saving.

Dust accumulation on PV surface panels is a crucial factor affecting their performance. It is more frequently noted in the desert zones. The effect of dust on the electrical behavior of damaged PV panels was investigated in this study. Three panels are used: the degraded panels (with and without dust) and the reference panels; they are located in an industrial zone with a continental climate (Bordj Bou Arréridj, Algeria). The I-V and P-V characterization and degradation mechanism visualization are used. Also, a numerical simulation was conducted to calculate the five parameters of the three modeled PV panels (diode ideality factor (a), series resistance (Rs), Shunt resistance (Rp), photocurrent (Ipv), and diode saturation current (I0)). These parameters were utilized for the first time to study the impact of dust on their degradation rate and the PV panel behavior. The degradation rate and the annual degradation rate of each parameter are affected by dust differently. The power degradation rate is increased by 5.45%. The Isc and Imax degradation rates are climbed by 6.97% and 6.0%, respectively. Vmax and Voc degradation rates decrease by 1.20% and 0.35%, respectively. Dust increased the rate of degradation for a, Iph, and I0 by 4.12%, 6.99%, and 68.17%, respectively. For Rs and Rp, the degradation rate was reduced by 4.51% and 20.01%, respectively. An appropriate netoiling approach must be considered because dust, even in non-desert areas and industrial zones, has a significant impact on the electrical characteristics degradation of a PV panel.

The current experimental study conducted in Ouled Sidi Brahim (Algeria) seeks to understand how the direction of the walls affects their temperature in the summer. A small red brick house of 20×20×20 cm 3 was used for the test, and throughout the experiment, the temperature was recorded every minute at the center of each wall facing the four cardinal points (East, West, North, and South) for 24 h (day and night). A digital acquisition device based on an Arduino board was realized to record the temperature on different days at the end of June, July, August, and the beginning of September. Only when solar radiation is present during the day can the influence of the walls' orientation be detected. The temperature of the walls remains nearly constant at night and drops from sunset to daybreak. The wall facing east is the hottest in the morning during the summer. The west-facing wall, on the other hand, is the coolest, especially in the morning. In the early summer, the west-facing wall is the hottest in the afternoon. It will, however, be replaced by the south wall at the end of the season. The temperature of building walls is significantly affected by the sun's daily and annual trajectory.

Algeria currently has a number of 24 functional photovoltaic power plants on its national territory, which are poorly investigated. This study focuses on the performance analysis of one of these existing solar power plants. It is located in Ain Skhouna, situated in Saida province, and has a capacity of 30 MWp (polycrystalline solar cell technology). This study was carried out according to the standardized norms IEC 61,724 (IEC) using one year (2018) of data. A linear relationship between the monthly module and ambient temperatures was evaluated (R2 = 0.994). The monthly total loss increases linearly with the increase in monthly ambient temperature and solar irradiation (R2 = 0.98). The system efficiency, PV efficiency, and performance ratio are affected by ambient temperature. The average monthly PV, system, inverter efficiencies, and PR were 13.78%, 13.29%, 96.68%, and 85.52, respectively. These results indicate that this PV power plant remains in very good working condition after two years of service. The effect of climate on PV plant performance was investigated in Algeria by comparing two climates: a semi-arid and a hyper-arid. The results indicate that the semi-arid climate is more favorable than the desert climate for PV power plants for producing electricity and that ambient temperature is a more essential parameter than solar irradiation.

Unfortunately, most developing countries lack meteorological data from weather stations due to a lack of measurement instruments or the absence of these stations. Currently, a variety of spatial databases, such as NASA/Power, Meteonorm, Solargis, and others, provide solar irradiation data for various places and time intervals. The goal of this study is to verify the accuracy of solar irradiation data from the National Aeronautics and Space Administration (NASA) database (free estimated data) by comparing them with ground-based measurements taken at four distinct locations in Algeria and Mauritania. Using six statistical parameters, data downloaded from the NASA site for 34 years, from 1984 to 2017, were averaged and compared to ground-based data recorded at M'Sila, Saida, Tamanrasset, and Nouakchott for one year (365 days) on daily (n = 365), monthly (n = 30 or 31), and annual (n = 12) time scales. It has been found that in the absence of daily measured global horizontal irradiation data for one year, the estimated multi-year average NASA data can be used instead. The use of estimated data over a long period is recommended. In the absence of actual solar irradiation data, solar energy projects in Algeria and Mauritania can rely on NASA's estimates.

Accepted: 23 November 2021 Solar energy is the most important green energy source that may be used to address the problems caused by conventional energy sources. The research in this paper aims to evaluate the solar energy potential of M'Sila, an Algerian internal region, and to determine which technology, among those currently available on the market, is adequate for harnessing that potential for electricity production (PV and CSP). This assessment was based on data (daily temperature and daily solar irradiation) collected at M'Sila weather station for one year and from the NASA site for 34 years from 1984 to 2017. These data were treated with excel 2016 software to determine the total horizontal, diffuse and direct normal solar irradiation. During the study period, the total solar irradiation falling on a horizontal surface in M'Sila (GHI) was estimated to be 1.79 MWh/m2/year. The diffuse solar irradiation incident on a horizontal surface (DHI) and direct normal irradiation, respectively, were estimated to be 594.88 kWh/m2/year, 2117.93 kWh/m2/year. M'Sila is a favourable land for the installation of concentrating solar power plants and photovoltaic panels due to its significant potential energy. The parabolic trough system is recommended. While polycrystalline PV modules should be promoted and installed in M'Sila

Amid all renewable energies, solar PV is of particular interest, mainly in Africa. Mauritania is an example of African countries which, gives great concern to produce electricity via PV installations. This study is carried out on the performance evaluation of a 954,809 kWp photovoltaic array made up of micro-amorphous silicon situated in Nouakchott (capital of Mauritania) at Sheikh Zayed solar power plant. The measures of one year of operation from September 2014 to August 2015 were evaluated according to the IEC 61724. The results obtained demonstrate that the photovoltaic array performances depend on both insolation and environmental conditions. The array capture loss ranges vary from a minimum value of 1.63 h/day to a maximum value of 2.46 h/day. So, the system loss is relatively stable, with an average value of 0.12 h per day. The monthly performance ratio varies from 0.61% in August to 0.71% in November, with a monthly average value of 0.66%. The monthly average capacity factor achieves its maximum and minimum in October (20.54%) and January (11.66%), respectively. The energy generated by the PV array (Edc) and the energy fed to the utility grid (Eac) during November moth, are affected by the insolation and the module temperature. However, wind speed variation does not influence those energies. Two linear models, depending on insolation and module temperature, are proposed for the evaluation of Edc and Eac during this month. These laters present a coefficient of determination (R2) of 0.96.

this paper presents an evaluation of the performance degradation of photovoltaic modules after six operation years in a steppe region environment in Algeria. The objective is to understand the performance of photovoltaic modules can be degraded due to several factors, namely, temperature, humidity, irradiation, dust and mechanical shock. This degradation results in the progressive damage to the characteristics of a component or a system which can modify its ability to operate within the limits of the acceptability criteria and which is caused by the operating conditions.

Earthen building materials have been used in all antique civilizations (Greek, Roman, Egyptian, Aztec, etc.). Undamaged earthworks of these civilizations still exist nowadays. Earthen buildings are known as passive solar buildings, i.e. naturally air-conditioned. This is due to the low thermal conductivity of their construction materials. Traditional building materials based on earth offer the following advantages: easily accessible, inexpensive and above all environmentally friendly. They are manufactured by hand, but their manufacturing techniques vary from region to region even in the same country. Unfortunately, these natural materials are almost out of service in Algeria, despite their assets. The first objective of this investigation is to determine the thermal conductivity of traditional building materials obtained by mixing two kinds of soil (agricultural and soil taken from a type of desert landscape (Hamada)), separately, with different amounts of straw, according to the expertise of the inhabitants of M’Sila (a province of Algeria). The second purpose is to find out the best mass proportion (soil/straw) which gives the lowest thermal conductivity of the obtained earthen materials.

The present paper shows the performance analysis of a photovoltaic system of 15.936 MWc (loop 1), a part of the 30 MWc photovoltaic power station of Saida (a province of Algeria).This investigation concerns one month of study (April 2019). The analysis done was evaluated according to IEC 61724. The parameters studied are the reference efficiency (Yr), the PV field yield (Ya), the final yield of the photovoltaic plant (Yf), the performance ratio ( PR), the efficiency of the PV module (ηpv), the efficiency of the inverter (ηinv), and the efficiency of the photovoltaic system (ηsys).The results show that the monthly reference yield, the photovoltaic field yield, and the final yield of the photovoltaic plant are 6.83 h/d, 5.98 h/d, and 5.81 h/d respectively. They are proportional to the energies Eac and Edc. The average monthly efficiency of the field and system are 13.74% and 13.33%, respectively.The monthly-standardized performance index (PR) presents an average value of 85.75%, which is greater than 80%. This means that the performance of this PV plant approaches the ideal performance in the STC conditions.Therefore, Ain Skhouna photovoltaic power plant is in good operating condition, without degradation.

The use of probability density functions (pdf) is directly linked to the nature of the data to which they relate. Some have good estimation capacity for small number of data, others require a large number of observations. In this study, the most probability distribution function for modeling the global solar radiation in Campo Grande, MS (Brazil) was determined. The global solar radiation data used for the analysis consists of daily average global solar radiation collected from University of Mato Grosso do Sul which span over the period of one year from January 2016 to December 2016. Various distribution functions were tested in this study and the most suitable one is determined using four different goodness of fit tests. The tested distributions used are Weibull, Rayleigh, Gamma, Lognormal, Rician and Frechet distributions. Four performance indicators; Mean Absolute Error (MAE), Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE) and Coefficient of Determination (R 2) were calculated to evaluate the adequacy criteria of the chosen distributions. The best distribution that fits well the global solar radiation observations in Compo Grande region was the Frechet distribution, followed by Weibull and Rician distributions. The worst distributions are given by Rayleigh and Lognormal. This paper is useful as first-hand information in the prediction of future global solar radiation for Campo Grande having known the past behavior and for fixing the missing data.

Sulfur dioxide (SO2) is considered the most widespread pollutant that threatens human and environmental health. Seasonal variation revealed higher levels of SO2 on cold days. The variations of the day revealed a higher concentration of SO2 indicating traffic influence, especially during peak hours. The analysis of hourly/daily/annual means identified an increasing trend in SO2 concentrations, implying that emission control systems and the technological improvement of engines and fuels were not sufficient and, therefore, points to the need for better subsidy mechanisms for the control of pollutants and effective emission reduction strategies, environmental agencies, should prioritize considering local realities.

Global solar radiation is needed for the analysis and scaling of solar conversion systems; however, global measurements of solar radiation are not available in all Algerian cities. The use of empirical models using an accessible parameter is a solution to this problem. In this study, seven empirical Models namely Hargreaves and Samani, Chen, M.F. Li, H.Li, Bristow and Campbell, Okonkwo and Abraha Savage have been employed to estimate daily average global solar radiation on the horizontal surface. These models use extreme temperatures (minimum and maximum). They were applied to three south Algerian sites (Biskra, Ghardaia, and Tamanrasset). The analyzed data were provided by the NASA site and cover four years (2001-2004). The validation of the models for predicting daily global solar radiation was done using four statistical parameters (R2, MBE, RMSE, and RPE). The results show that Bristow and Compbell Model shows better performance than the other models in all sites. A new model is proposed for each site. The results show that this later is the best one compared with the seven models analyzed. Therefore, the developed model can be suggested to estimate daily global solar radiation using only extreme air temperatures in south Algeria.

Wind potential estimation requires an analysis of wind characteristics (wind speed density and wind direction). In this study, the applicability of two distribution models named Weibull and Inverse Weibull aiming to characterize the wind speed distribution in Campo Grande-Ms (Brazil) is investigated. The wind speed data collected from Campo Grande-Ms National Institute of Meteorology (INMET) at 10 m height for 5 years from January 2013 to December 2017, at an hour interval, are used. The method of maximum likelihood estimation is applied to calculate the parameters of the selected distributions. The best distribution function is chosen based on three goodness-of-fit statistics, namely; mean absolute percentage error (MAPE), root mean square error (RMSE), and coefficient of determination (R²). The obtained results indicate that the Weibull distribution provides a more accurate and efficient estimation than Inverse Weibull distribution. Therefore, Weibull distribution can be used to better estimate wind speed distribution in Campo Grande-Ms (Brazil) than Inverse Weibull distribution.

The importance of statistical analysis in the field of energy for environmental engineering is shown in this research paper, in which the adequacy of the data sets of clarity index with the model of “best” probability (based on the criteria used) was studied. In Campo Grande which is the capital of the Brazilian state of Mato Grosso do Sul, located in the Center-West region of the country, there is a predominance of the atmospheric conditions of low cloudiness, with a high frequency of days with a clear sky and in consequence a low-frequency of days with cloudy sky. The aerosols resulting from the burning of sugarcane influence the sky conditions in Campo Grande thus reducing the frequency of the clear sky.

— The solar energy gives life to humans and all living beings on earth. Solar energy is used to produce thermal as well as electrical power. Solar energy and other renewable sources, allow us to meet the demand for energy while providing a cleaner and greener footprint. In this work, we have developed a software using the programming language MATLAB GUIs (also known as graphical user interfaces or UIs) for the estimation of solar radiation for the different types of the sky in Algeria. The software contains a database (latitude, longitude, and altitude) of all the regions of Algeria. The program gives the opportunity to compare the values estimated by the theoretical models (Perrin de Brichambaut, Lui & Jordon, Hay & Davies, Klucher and Reindl) and the values measured by the meteorological station in the region of M’sila. A good agreement was found between the measured and recorded values.

Earthen building materials have been used in all antique civilizations (Greek, Roman, Egyptian, Aztec, etc.). [1] Undamaged earthworks of these civilizations still exist nowadays. [2] Earthen buildings are known as passive solar buildings, i.e. naturally air-conditioned. This is due to the low thermal conductivity of their construction materials. Traditional building materials based on earth offer the following advantages: easily accessible, inexpensive and above all environmentally friendly. They are manufactured by hand, but their manufacturing techniques vary from region to region even in the same country. Unfortunately, these natural materials are almost out of service in Algeria, despite their assets. The first objective of this investigation is to determine the thermal conductivity of traditional building materials obtained by mixing two kinds of soil (agricultural and soil taken from a type of desert landscape (Hamada)), separately, with different amounts of straw, according to the expertise of the inhabitants of M’Sila (a province of Algeria). The second purpose is to find out the best mass proportion (soil/straw) which gives the lowest thermal conductivity of the obtained earthen materials.

An accurate knowledge of solar radiation data for a given location is required for any project aimed at exploiting solar energy. The present paper evaluates the solar energy potential of M'Sila, (internal region of Algeria). This assessment is made based on data collected at the M'Sila weather station for 365 days by 5-minute intervals. The study site is located at a latitude of 35° 42`07``, longitude of 4° 32`43`` and an altitude of 441 m above the sea level. The maximum radiation received in M'Sila during the day does not occur at a fixed time during the year. It fluctuates around an average value of 11:40. This maximum radiation was recorded between 9:14 and 13:59. The representative days of the radiation reaching the ground of M'Sila are different from those relating to extra-terrestrial radiation. They vary from year to year. The month of July is the sunniest month in M’Sila with a total insolation of 790.14 MJ/m2. The month of December is the least sunny month with a total insolation of 242.52 MJ/m2. M'Sila receives a total solar energy of 6316.42 MJ/m2 per year. That means an average insolation of 526.37MJ/m2 per month and 17.31 MJ/m2 per day. M'Sila has an important solar energy potential that deserves to be exploited.

Global solar radiation is an important parameter in the study of any solar energy project. Global solar radiation measurements are not operational in all cities of Algeria, due to high cost of acquisition, maintenance and technical complexities. To overcome this problem the use of empirical models based on temperature as an interesting and accessible parameter is necessary. In this study, six empirical models namely; Hargreaves and Samani model, Chen model, Li 1 model, Li 2 model, Bristow and Compbell model and Okonkwo model, have been selected from literature to estimate monthly global solar radiation from air temperature data of Djelfa. The city of Djelfa (Algeria) is taken as the sole case of study. The performance of those models was evaluated through several statistical indicators (R², RMSE, MBE, MPE and RPE). The results show the superiority of Li 2 model on the studied models. Based on the evolution of monthly global solar radiation as function of extraterrestrial radiation and air temperature variation, a new model was developed. Comparison between model 4 and the developed one indicates the superiority of the new model. This model has been verified for other Algerian cities such as Biskra and Ghardaia. The data of these regions (global solar radiation, maximum and minimum air temperature) were taken from NASA site web. The results show also the superiority of this new model for these two regions. Therefore, the developed model can be suggested to estimate monthly global solar radiation using only air temperature.

This research document presents a new insulation material for solar thermal collectors. Tests were carried out in the laboratory, on an active solar energy demonstration system (ET 200), illuminated with a halogen lamp instead of sun. In this paper, the polystyrene used as insulation in the ET 200 flat plate solar collector was replaced by the cheaper natural material based on clay and straw. The polystyrene in the experimental device is placed under the absorber plate and along the edges of the casing containing the components of the solar collector. In this work, only the polystyrene of the four similar edges was replaced by the composite material. The use of the clay and straw as insulation material instead of polystyrene increased temperature difference (T2 − T1) between the inlet and the outlet of the absorber by 0.9±0.14 °C (p < 0.05); thus, increasing the useful power transmitted to water in the solar collector. Compared to polystyrene, tank water was well heated using the proposed material (p < 0.05). This latter also improved the performance of the solar collector by 5.77%. So, it is recommended to use the cheapest nonpolluting material based on clay and straw instead of synthetic insulation to improve the performance of the solar collector.

In large urban centers, the major contributors to much of the degradation of air quality are motor vehicles on the road. In some cities, the levels of concentrations of air pollutants have reached levels that pose a risk to human health. Ozone (O3) is a secondary pollutant formed from photochemical reactions of nitrogen oxides (NOx). Numerous studies have found associations between daily levels of ozone with a number of health effects. In the state of South Mato Grosso (MS), there has been a growing increase of ozone levels in the atmosphere in recent years. Considering the above, this study aimed to identify the best estimator for the Weibull distribution, in analyzing the ozone concentration, for the city of Campo Grande-MS. For this, electronic data from the continuous air monitoring station located on the campus of the Federal University of South Mato Grosso (UFMS), Campo Grande was utilized. According to the results presented by the tests, it was verified that the LSRM method presented the poorest performance. The EPFM, MOM and MSDM are most efficient methods to adjust the Weibull distribution curves for the evaluation of ozone concentrations in the atmosphere.

Among the causes of global warming, figure the modification of the nature of the soil. This paper presents an experimental study of the effect of soil type on global warming using a laboratory thermal collector. This paper shows also another application of this experimental apparatus used generally for parametric study in order to improve its efficiency. The experimental device (ET200) used in this study consists of a thermal collector and water reservoir. The thermal collector receives solar energy from a halogen lamp (which simulates solar radiation) on its glass surface. The same amount of the following materials is spread over the receptive surface of the thermal collector; agricultural soil, local regional soil (soil of the region where these experiments were performed), cement and plaster. The same experimental conditions are kept up for each material used as receptive surface cover. The incident heat flux is influenced by the nature of the receptive surface coverage. Indeed, the receptive surface covered by agricultural soil and local soil receives the same incident flux. This flux is reduced by 4% in case of cement and 8% in case of plaster (i.e; relative to flux received by agricultural soil and local soil). The reception glass covered with agricultural soil transmits better the energy received from the lamp to the heating medium (heat transfer fluid); this energy is lessened by 9% in the case of local soil, by 27% in the case of plaster and 18% in the case of cement. So, the incident solar radiation is well reflected by the plaster, it is less reflected by the cement and it is the least reflected in the case of agricultural soil and local soil. So, the thermal collector demonstrates that air temperature is affected by the nature of the soil. It is recommended to preserve agricultural lands and do not transforming them into urban areas in order to reduce the effect of global warming.

The position of the solar conversion systems relative to the sun affects directly their energy output. Optimum tilt angle is the inclination which maximizes the amount of intercepted solar energy. This paper aims to find the best inclination angle of fixed solar conversion systems in M’Sila region, (monthly, seasonally and annually) theoretically (using empirical models namely; Liu & Jordan model, circumsolar model, Hay model, and Reindl model) and experimentally. Reindl model is the most suitable for M’Sila region because, it gives values close to those found experimentally. It is preferable to change the tilt angle of solar conversion systems monthly or seasonally instead of fixing them, to gain more energy.
