?	pvgis.mounting_position
	Default “FREE STANDIN” For fixed systems, the way modules are mounted will influence module temperature, which in turn affects efficiency. Experiments have shown that if air movement behind the modules is restricted, the modules can become significantly hotter (up to 15°C at 1000W/m2 sunlight). data-ts="pvgis.mounting_position_helper_3"> In the application there are two possibilities: stand-alone, which means the modules are mounted on a rack with air circulating freely behind the modules; and roof added/building integrated, which means the modules are completely integrated into the wall or roof structure of a building, with little or no air movement behind the modules. data-ts="pvgis.mounting_position_helper_4"> Some mounting types fall between these two extremes, for example if the modules are mounted on a roof with curved roof tiles, which allows air to move behind the modules. In such cases, the performance will lie somewhere between the results of the two calculations that are possible here. In such cases, to be conservative, the added roof/building integrated option can be used.

?	pvgis.peack_installed_photovoltaic_power
	Default “1” This is the power that the manufacturer states that the photovoltaic array can produce under standard test conditions, which are a constant solar irradiance of 1000 W per square meter in the array plane, at an array temperature of 25°C. Peak power must be entered in peak kilowatt (kWp).

?	pvgis.slope_azimut
	If you have the possibility to choose the angle and azimuth or orientation of your mounting system for your solar installation, whether on a flat roof or on the ground (concrete slab), you will check the optimization both angle and azimuth. PVGIS24 can calculate optimal values for slope and aspect (assuming fixed angles throughout the year). • Slope 15 if southern hemisphere / Optimize the slope This concerns the angle of the photovoltaic modules in relation to the horizontal plane, for a fixed installation (without monitoring). • Azimuth 180 if southern hemisphere / Optimize the angle. The azimuth, or orientation, is the angle of the photovoltaic modules relative to the direction: NORTH 180° NORTH-WEST 135° WEST 90° SOUTH-WEST 45° SOUTH 0° SOUTH-EAST 45° EAST 90° NORTH-EAST 135°

?	pvgis.system_loss
	Estimated system losses are all losses in the system that cause the energy actually delivered to the power grid to be less than the power produced by the PV modules. • Cable loss (%) / default 1% PVGIS24 is based on international standards for line loss in cables. this loss is estimated at 1%. You can reduce this loss to 0.5% if the quality of the cables is exceptional. You can increase the line loss of the cables to 1.5% if the distance between the solar panels and the inverter is greater than 30 meters. • Inverter loss (%) / par défaut 2% PVGIS24 is based on the average of inverter manufacturer data to estimate the production transformation loss. The international average today is 2%. You can reduce this loss to 1% if the quality of the inverter is exceptional. You can increase the loss to 3% to 4% if the chosen inverter offers a transformation rate of 96%! • PV loss (%) / default 0.5% Over the years, the modules also tend to lose some of their power, so the average annual production over the life of the system will be a few percent lower than the production in the first few years. The various international studies including those of Sarah and Jordan KURTZ estimate an average production loss of 0.5% per year. You can reduce this production loss to 0.2% if the quality of the solar panels is exceptional. You can increase the loss from 0.8% to 1% if the solar panels chosen are of average quality!

?	pvgis.simulator.use_terrain_shadows
	The solar radiation and photovoltaic production will change if there are local hills or mountains that block sunlight during certain periods of the day. PVGIS can calculate the effect of this by using data on ground elevation with a resolution of 3 arc-seconds (approximately 90 meters). This calculation does not take into account shadows from very close objects such as houses or trees. In this case, you can upload your own information about the horizon by checking the "Download horizon file" box in CSV or JSON format.

	- PVGIS-SARAH3 : Données disponibles de 2005 à 2023. Couvre l’Europe, l’Afrique, la majeure partie de l’Asie et certaines régions d’Amérique du Sud. Basé sur les observations satellitaires, il offre une précision élevée pour l’irradiance solaire. - PVGIS-SARAH2 : Produit par CM SAF pour remplacer SARAH-1 (PVGIS-SARAH). Il couvre l’Europe, l’Afrique, la majeure partie de l’Asie et certaines régions d’Amérique du Sud. Période : 2005-2020. - PVGIS-ERA5 : Dernière réanalyse mondiale fournie par l’ECMWF (Centre Européen pour les Prévisions Météorologiques à Moyen Terme). Période : 2005-2023. La réanalyse des données sur le rayonnement solaire présente généralement une incertitude plus élevée que les bases de données satellitaires. Par conséquent, nous recommandons d’utiliser les données de réanalyse uniquement lorsque les données satellitaires sont manquantes ou obsolètes. Pour plus d'informations sur les bases de données et leur exactitude, veuillez vous référer au PVGIS page Web sur les méthodes de calcul.
