Listed below are the major steps followed and the costs involved in setting up a Solar Rooftop plant

however the steps and the method of setting solar rooftop may vary across regions, based on the

different local conditions such as administration, legislations , guidelines and other factors

The owner needs to identify the purpose of setting the solar rooftop by conducting a need

assessment wherein the place of setup should also be identified.

What is Solar Rooftop?

Scope of the project

Geo-tagging of Solar Rooftop installation in Govt. Institutions in Chandigarh

The site for solar rooftop needs to be assessed with regard to the resource available

(including shadow effects) and the energy needs & load profiling (In electrical engineering,

a load profile is a graph of the variation in the electrical load versus time). A load profile

will vary according to customer type (typical examples include residential, commercial and

industrial), temperature and holiday seasons.

There are national and state level policies and incentives for promoting solar rooftop in

India. The owner of rooftop solar should look forward to all these for attaining additional

benefits also.

The owner of the rooftop plant should identify the vendor or the installer for executing the

installation from MNRE channel partner list.

Legal and Regulatory Framework

To set up a solar rooftop, there are different modes of financing through which the

owner can get its plant financed and can avail the subsidies.

The owner and the installer collectively need to finalize the design of the Solar Rooftop

system, so that equipments can be finalized.

The owner needs to look for Contracts and Bids if there are any. This step also involves

preparation of bidding documents for the selected system including plant monitoring.

This involves Installation & Commissioning of the plant and a third-party Inspection as per the

Tender Document.

After installation and commissioning of the plant, installer needs to know the maintenance

requirements for the solar power plant. Periodic checking of the power plant also comes

under this step.
