In grid connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using power conditioning unit and is fed to the grid either of 33 kV/11 kV three phase lines or of /220 Volt three/single phase line depending on the capacity of the system installed at institution/commercial establishment or residential complex and the regulatory framework specified for respective States. These systems generate power during the day time which is utilized fully by powering captive loads and feed excess power to the grid as long as grid is available. In case, where solar power is not sufficient due to cloud cover etc., the captive loads are served by drawing power from the grid.

Consumer Details

Capital Expenditure (CAPEX) Model

This is the most common business model for solar deployment in India. In this model the consumer purchases the solar system, by making 100% of the payment upfront or financing the system, often through a bank.

Renewable Energy Service Company (RESCO) Model

Under this model, a RESCO developer finances, installs, operates and maintains the rooftop solar power plant. The developer signs an agreement with the rooftop owner. The rooftop owners may consume the electricity generated, for which they have to pay a predecided tariff to RESCO developer on a monthly basis for the tenure of the agreement. Based on the consumption choice and requirement, the model is further divided into two types – Rooftop Leasing and Power Purchase Agreement (PPA).
