Your roof gets billed-for sunshine every single day. Solar panel installation converts it into electricity that runs your home first and spins your meter backwards with net metering — with subsidies making residential rooftop systems pay for themselves in roughly 4–6 years, then generate essentially free power for 20 more.
TrueInstaller connects you with verified solar installers who handle the full journey: site survey, sizing, structure, panels, inverter, net-metering paperwork and after-sales service.
System types
- On-grid systems — the residential default; excess power exports to the grid via net metering.
- Hybrid systems — battery backup rides through power cuts.
- Off-grid systems — farms and sites without reliable grid supply.
- Solar water heaters — the simplest solar payback for hot-water-heavy homes.
Indicative pricing (before subsidy)
| System size | Approx. price | Typical output |
|---|---|---|
| 3 kW on-grid | ₹1.8 – ₹2.4 lakh | ~360 units/month |
| 5 kW on-grid | ₹2.8 – ₹3.8 lakh | ~600 units/month |
| 10 kW on-grid | ₹5.5 – ₹7.5 lakh | ~1,200 units/month |
Central subsidy schemes can cut residential costs substantially — installers confirm current benefits for your state in the quote.
Installation process
- Post your requirement — monthly bill amount, roof type and your city.
- Site survey & sizing — shadow analysis, structure design and system size matched to your usage.
- Installation — structure, panels, inverter and cabling (2–4 days on site).
- Net metering & handover — DISCOM paperwork, bidirectional meter, monitoring app setup.

Frequently asked questions
What roof area does a system need?
Roughly 80–100 sq. ft. per kW for standard panels — a 3 kW system fits comfortably on most independent-house roofs.
What maintenance do panels need?
Water rinsing every few weeks and an annual health check. Panels carry 25-year performance warranties; inverters 5–10 years.
Does solar work in monsoon and winter?
Yes — generation dips on cloudy days but never stops; systems are sized on annual averages so the economics already include monsoon.
