How it works

The same seven steps, whichever service you pick

1

Free site survey

We visit your roof, measure shadow-free area, check the structure and study your last twelve electricity bills.

2

Design & quotation

You receive a system size, a generation estimate, a payback figure and a complete bill of materials — in writing, with nothing hidden.

3

Subsidy registration

We register your application on the PM Surya Ghar national portal, file the Bihar Govt. top-up alongside it, and obtain DISCOM feasibility approval.

4

Installation

Galvanised structure, panels, inverter, DC and AC protection, earthing and lightning arrester — typically two to four days.

5

Testing & commissioning

String voltages, insulation resistance, earth resistance and generation all measured against design and recorded on a checklist.

6

Net meter & subsidy

DISCOM inspection, net-meter installation, and the subsidy claim followed up until it reaches your bank account.

7

Service & AMC

Five free visits in the first year, generation reports, and an AMC to keep the plant at its rated output for decades.

Not sure which one?

Tell us your bill. We will tell you the answer.

Most people arrive asking for "solar" and leave with something more specific — a 3 kW on-grid system, or a hybrid because the evening cuts matter more than the savings, or a pump because the diesel bill is the real problem.

A free site survey settles it in about an hour, and you get the recommendation in writing whether or not you go ahead with us.
