RESCO MODEL FOR ROOFTOP INSTALLATION
Under this model, a third party—a solar power developer installs the plant on the rooftop and sells the generated power to the consumer. The consumer does not have to make any investment. The tariff at which the consumer buys the solar power is mutually agreed upon through a power purchase agreement (PPA). For consumers, in addition to the advantage of zero investment, they do not have to pay for the O&M costs as well, as these are usually the responsibility of the developer. This model is more feasible in case of institutional consumers, residential complexes etc., as developers are willing to offer long term PPAs as well as O&M contracts for such large-scale installations.
