Rooftop Solar + Storage: A Viable, Win-Win Solution For Consumers & DISCOMS Now

In Clean Facts, Clean Talk, News, Opinions, Renewable Energy, Sustainability

The declining cost of lithium-ion batteries, along with that of solar, is likely to change the future dynamics of the Indian power sector. The viability of storing solar power using batteries and using it during peak times is increasing due to declining battery prices.

At present, in India, commercial and industrial (C&I) consumers face steep electricity costs, as well as frequent disruptions in the power supply. Installing a solar plus storage system can address both these issues and significantly reduce the company’s electricity bills.

Rooftop solar with storage system is a win-win solution for both end consumers as well as the DISCOMS.

For consumers, the benefits are:

  • Reliable and affordable power
  • Ready backup power
  • Consumers can manage their demand using storage system and reduce their demand charges
  • Saving cost of alternate energy from diesel gensets
  • It is also an environmentally friendly option

For DISCOMS, it helps in reduction of transmission and distribution losses and saves on the investments in transmission and distribution infrastructure.

At present, a 1 MW rooftop/ onsite solar plant with 250 kW of battery storage (4 hr backup), is already a viable solution for commercial consumers across key states in India.

Solar+ storage is also a viable solution in certain states for group captive plants, open access third party plants as well as the residential segment (if subsidies are included).
