At European latitudes, AM is set at 1.5, a value used also as a reference for the tests conducted in laboratories on photovoltaic cells. AM equals to 0 when the radiation is measured on the outer surface of the atmosphere with no attenuation whatsoever.

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).
The advantages of using such data are: solar radiation data are then available in the whole of the area covered by the satellite images, for instance, the METEOSAT satellites cover Africa, Europe and most of Asia up to about 60°N, with an image resolution of a few kilometers.
The solar radiation data produced from the satellite images must be checked against measurements at ground level to get an idea of how large uncertainty there is in the satellite-based solar radiation data. This is known as the validation of the data.
The calculation takes into account the cost of buying and installing the PV system, the cost of maintenance, and the cost of financing. All these costs are then compared with the estimated PV energy production during the expected lifetime of the system. The calculation of PV electricity cost is done using a "Levelized Cost Of Energy" (LCOE) method.
The units of measurement are key to understanding the difference: So, while irradiance measures the power per area, solar irradiation measures the power per area during a period of time (an hour, for example). The amount of solar irradiance depends on several factors. What influences solar irradiance?

Solar radiation is then determined by equating the electrical energy to the product of incident solar radiation, strip area and absorptance. Then the position of the shutter is reversed, interchanging the electrical and radiation heating, and the second value is determined. Alternating the shade and the functions of the two strips compensates for minor differences in …
