Is solar energy a good option for electricity generation?

Among renewable energy sources solar energy attract more attention and many studies have focused on using solar energy for electricity generation. Here, in this study, solar energy technologies are reviewed to find out the best option for electricity generation. Using solar energy to generate electricity can be done either directly and indirectly.

Why do solar panels have a low power output?

The amount of light absorbed by the module's parts other than the solar cells contributes to the module's heating which leads to a decreased bandgap energy, resulting in a poor power output. Solar panels are mounted in certain height to vent off the excess heat energy.

What causes low PV power generation?

However, dust, snow or any other natural or artificial shadowing can reduce the amount of solar irradiation received by the module. In addition, dust and air pollutants are absorbed by humid air, resulting in soiling on the module-reduced irradiance, which causes low PV power generation. PV panel heats up because of the direct exposure to the sun.

What causes solar PV panel degradation?

Solar PV panel degradation (Gosumbonggot & Fujita, 2019) Reduced glass transmittance and overall PV power generation are the results of dust accumulation and soiling. According to studies, its effectiveness can be increased with the right cleaning system and regular cleaning.
