PROCEDURE TO INSTALL SOLAR ROOFTOP
Before designing a solar rooftop system, it is important to understand the consumption load of the house. Typically, a house has various sources of electricity and many appliances that consume it. By feeding this information into a simple online tool—solarmyroof.cseindia.
org—a consumer can determine the size of the rooftop system he needs, and the space and money required to install it.
To install the system, the consumer can approach one or more of the channel partners approved by MNRE. Channel partners are agencies empanelled by MNRE to install solar PV systems. Importantly, they facilitate individuals and small groups of clients to access the benefits available under the solar rooftop programme. Once selected, a channel partner submits a proposal to the rooftop owner as per site assessment and signs an agreement for the installation of the system, on basis of either capital expenditure or the RESCO model. The channel partner then applies for a net or gross metering connection from the concerned distribution company (DISCOM) on behalf of the roof owner. In general, it takes 45–60 days, depending on the state of the consumer, to get a net metering connection and installing a bidirectional meter.
To obtain the subsidy, the channel partner files an application for evaluation with the State Nodal Agency (SNA) or Energy Development Agency, set up by MNRE in every state to oversee the implementation of various schemes including solar rooftop, with all the relevant
details, including the technical and financial aspects of the project. The details of all state nodal agencies are available at http://mnre.gov.in/mission-and-vision-2/contact-us/
After evaluation, the project is forwarded to MNRE for final consideration and approval. Once approved, the subsidy is disbursed. Many channel partners install the system at lower capital expenditure, assuming they would receive the subsidy, effectively shifting the burden of waiting for disbursal of subsidy from consumers to channel partners.
