Learn MoreThe solar radiation may be characterized by the measured solar irradiance (power per area at a given moment) (or radiation) and by the solar insolation (the energy per area delivered over a specified time period). The solar radiance is an instantaneous power density in units of kW/m 2.
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”.
The P-V curve fluctuates more at solar radiation of 800–1300 W/m 2 compared to 100–700 W/m 2, which indicates that the higher the solar radiation, the greater its effect on the electrical power. To predict the maximum output power of PV modules under different radiation, the output power and voltage are firstly dimensionless by Eq.
The 13 sets of maximum power points corresponding to different radiations are shown in Fig. 6. Fig. 6. The P-V curve of photovoltaic modules under different radiation. Fig. 6 shows the data for the output power and voltage of the PV module under 100 W/m 2 - 1300 W/m 2 radiation conditions.
Conclusions Solar irradiance is of utmost importance for PV energy generation and can be affected in different ways. To a lesser extent, it is the variation of sunlight reaching the top of the atmosphere due to the sun cycle as well as the variation in sun-earth distance.
3.4. Difference in annual power generation of PV modules in winter and summer By processing the solar radiation data (Fig. 10), Solar radiation is divided into 14 levels, and all of the measured solar radiation are classified as 100 - 1,300W/m 2.
