Industrial Solar Power Systems have gained popularity in India with major industries resorting to solar power for avoiding grid outage situations

Solar power for industries is quintessential for meeting the 100 GW solar mission of India.


Electricity users in India are typically classified into 3 different categories as Commercial, Industrial and Domestic consumers. A significant 44.2% of the entire electricity generated in India is used for industrial consumption, making it one of the most important sectors with respect to electricity demand. The grid tariff for industrial consumers can go as high as INR 8/unit for non-peak hours and is much more for peak usage.


Pertaining to heavy usage, especially during the peak hours, electricity constitutes major variable cost for industries. Industrial solar power, therefore, is a way to reduce the peak loading of the grid and do away with high tariff rates for the peak hours.


Heavy peak usage & large available area make solar a perfect energy solution for industries.


A solar power system’s value decreases over time due to the wear & tear of parts and reduction in efficiency of solar panels. The accelerated depreciation benefit allows the commercial and industrial users of solar power to depreciate the assets built as Solar Power Plant at a much higher rate than general capital assets. This allows the user to then claim tax benefit on the value depreciated in a given year.
