Context:- A team of Indian and international researchers have found that aerosols, dust, and clouds reduce solar energy generation from photovoltaic and rooftop solar installations resulting in substantial economic impact.
They estimated that the impact of total aerosol optical depth on Photovoltaic and rooftop installations amount to annual financial loss of upto 1.55 million Rupees.This estimation can help the Indian solar energy producers and the electricity handling entities for efficient transmission and distribution system operations and grid stability optimization.
Recently, solar energy generation has been widely used in developing countries such as India, which has sufficient solar resources. However, clouds and aerosols limit the solar irradiance causing performance issues in the PV and CSP plant installations. To achieve the large-scale development of a solar system requires proper planning, and there is a need to estimate the solar potential.
Researchers at the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, an autonomous research institute of the Department of Science and Technology (DST) Govt. of India and National Observatory of Athens (NOA), Greece, studied the impact of aerosols and clouds on the solar energy potential over a high-altitude remote location in the central Himalayan region with analysis and model simulations.
The study published in the journal of Remote Sensing show that on an annual basis, the total aerosol attenuation for the total solar radiation incident on a horizontal surface or global horizontal irradiance (GHI) was 105 kWh m-2 and 266 kWh m-2 for direct solar radiation received from the sun or beam horizontal irradiance (BHI); respectively.
