Solar power & backup power installation

Solar power & backup power installation in India

Updated 4 November 2026

In India a rooftop solar system is priced at roughly ₹55,000 to ₹85,000 per kW, and a small home system of 1 kW is listed at about ₹40,000 to ₹50,000. Battery backup and off-grid systems cost more. For current offers, describe your power needs in a request on BlaBlaPrice.

Subsidy and the rules to check

One installer's listing says residential hybrid solar systems are eligible for a solar subsidy of up to ₹78,000. Ask whether the quote includes the subsidy and who applies for it. Solar installers need an electrical contractor licence, and business registrations such as GST, Udyam (MSME) registration and a trade licence are commonly required, so ask for the licence number and a GST invoice.

Season and the climate

The climate is hot all year, with a wet season and a dry season. Roof work and cable runs are easier in the dry season, and heavy rain can delay the installation. Output is strongest on sunny days, so the dry season is a practical time to plan a new system. Ask the installer how the wet season affects the schedule before you sign.

Phases, batteries and units

Say whether your supply is single-phase or three-phase, since the system type and the inverter depend on it. Systems are sized in kW for the panels, and batteries are given in capacity, usually in kWh, so ask for both. Give the site address and the roof details, because installation on a flat roof differs from a sloped one, and the cost of the cable run changes with the distance between the roof and the meter.

What to put in your request

Say which system you want, such as on-grid, hybrid or off-grid with battery, and the power you need in kW. Add the battery capacity you want to back up, the number of phases, any equipment you prefer, the site address, your deadline and your budget. Detailed requests get quotes that can be compared directly.

BlaBlaPrice is free for buyers. Describe your home or business in a chat and add a photo of the roof if you have one. The AI reads the request, asks for missing details and looks through sellers' websites and price lists in India, then shows the prices and businesses it found. Sellers registered on BlaBlaPrice reply in the chat with their own offer and terms, and your contacts stay hidden until you decide to share them. Create a request, or see electrical installation.
