Abstract : Numerous consumers have become prosumers as a result of Government regulations and incentives designed to promote the production of zero-carbon electricity. These prosumers are now actively engaged in exporting surplus power generation to the grid and importing electricity from the grid during periods of increased demand. Two models are taken into consideration for analysis in this paper. In a decentralized model, the capital investment is made by the prosumer; whereas in an economically centralized model, on the other hand, the capital investment is made by the Renewable Energy Service Company (RESCO). The centralized model has two modes of operation: in mode 1, RESCO pays rent for the provided space, and in mode 2, RESCO offers a discounted rate for each unit the customer uses from RESCO. We look at the economics of both approach strategies in India that are relevant to home prosumers who install rooftop solar and storage systems. These two methods are used to quantify the profit and payback period for each stakeholder in this paper. The maximum profit is made by 70% of prosumers in the decentralized concept. The results demonstrate that for domestic prosumers with lower demand, the decentralized approach performs well. When significant energy demands exist, the centralized model is preferable.
