A study conducted by the Council on Energy, Environment and Water (CEEW) has found that the households owning rooftop solar systems can save up to 95 per cent on their electricity bills. The study, undertaken by CEEW in the jurisdiction areas of distribution company (discom) BSES Yamuna Power Ltd (BYPL) in east and central Delhi, also found that residents buying power from a community rooftop solar plant through a subscription plan could save up to 35 per cent on their electricity bills. These savings have been estimated over the 25-year lifetime of these systems.

The Council’s study found that involving electricity distribution companies, designing innovative business models, and introducing financial incentives are a key to scaling up rooftop solar in the residential sector.

According to the report, key challenges for residential consumers in adopting rooftop solar include high capital cost, lack of access to finance, lack of consumer awareness, issues with roof ownership and access, and a roof lock-in period of 25 years.

Through the CEEW-BYPL collaboration, BYPL has created ‘fit-for-purpose’ business models that will help to power electricity bills in this segment. The proposed business models could extend the rooftop solar market to all residential consumer segments across India. The models highlight options to spur demand for rooftop solar among residential consumers including easy financing and solar subscription plans of varying durations. The on-bill financing model allows consumers to pay the cost of the rooftop solar system through savings on electricity bill over a duration of 7-8 years.
