The Ministry of New and Renewable Energy (MNRE) and the Bureau of Energy Efficiency (BEE) are close to finalising a star rating mechanism for solar Photovoltaic (PV) panels.
This is significant because till now the efficiency of energy generation equipment was not rated by the BEE and ratings were largely limited to household appliances such as air conditioners, fans and LED bulbs.
According to officials, the efficiency of panels will be assessed while factoring the energy output over the area covered by the panels. These panels will also be assessed on the annual degradation of PV equipment that leads to lowering of energy output.
