Four models are studied regarding the effective total irradiance on the PV panels as a function of the ambient temperature, wind speed, dust accumulation rate, and cleaning frequency. iv.
The Global Solar Atlas provides a summary of solar power potential and solar resources globally. It is provided by the World Bank Group as a free service to governments, developers and the general public, and allows users to quickly obtain data and carry out a simple electricity output calculation for any location covered by the solar resource database.

Solar Irradiance. The amount of energy striking the earth from the sun is about 1,370W/m 2 (watts per square meter), as measured at the top of the atmosphere. This is the solar irradiance.The value at the earth''s surface varies around the globe, but the maximum measured at sea level on a clear day is around 1,000W/m 2.The loss is due to the fact that some of the
The development of solar PV installations is based on the radiation of the chosen site; the latter (solar radiation) is the main factor in the production of electrical energy using solar panels . It can be affected by different environmental parameters such as dust, snow or by the atmosphere such as diffusion of the solar spectrum by air molecules, aerosols and clouds.

One of the most important factors to consider when designing a solar photovoltaic (PV) system is the level of solar irradiance at a potential location.
Thus at an equatorial location on a clear day around solar noon, the amount of solar radiation measured is around 1000 watts, that is 1000W/m (or 1.0 kW/m). When dealing with photovoltaic solar panels purely for the generation of solar power, a solar irradiance light level of 1.0 kW/m is known as one “Full Sun”, or commonly “Peak Sun”.
We can only get a fraction of this value inside the earth's atmosphere. The specification of PV modules is done by manufacturers under standard test conditions (STC) i.e., at solar irradiance equals 1000W/m 2. The irradiance of the sun available in a specific location tells how much power a rated solar panel can produce in that location.
