Why is solar irradiance important for PV energy generation?

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.

Does solar irradiance affect PV performance?

Some of the key findings are: Solar irradiance is the most significant factor affecting PV performance, with the strongest impact near the equator. Higher temperatures reduce PV efficiency, with a typical loss of 0.4–0.5 % loss per 1 °C increase.

How does solar radiation affect the performance of a solar panel?

This implies that an increase in solar radiation leads to increase in output current which enhances efficiency (performance) of a solar panel. However, the increase in solar radiation is followed by an increase in the PV cell temperature which has a bad effect on ball the studied parameters.

What is solar irradiance?

In recent years, solar energy technology has emerged as one of the leading renewable energy technologies currently available. Solar energy is enabled by the solar irradiance reaching the earth. Here we describe the characteristics of solar irradiance as well as the sources of variation.

How does spectral distribution affect solar irradiance?

PV modules are sensitive to the spectral distribution of solar irradiance . The Average Photon Energy (APE) metric assesses the effect of solar spectrum distribution on outdoor PV module performance . It represents the average energy of photons in the spectrum and is the ratio of integrated irradiance to photon flux density .

Where does solar irradiation come from?

As solar PV installations move beyond the mid-to-high latitudes of the United States, Europe, and China into hotter lower-latitude regions like Africa and Southeast Asia, PV systems will encounter higher dust levels, temperatures, and solar irradiance.
