- Backup for critical loads
- Zero-capex financing options
3 – 25 kW
Residential
Rooftop solar for homes
Sleek rooftop panels, a home battery and EV charging, managed from one app — with backup that kicks in before the lights flicker.
- 10 – 40 kWh home batteries
- EV charger integration
- Live monitoring app
How it works
From photon to power in four steps.
01Capture
Bifacial panels on single-axis trackers turn sunlight into DC power — harvesting light from both sides of every module.
Battery energy storage
Sunshine on demand, day or night.
Batteries bank the surplus your panels make at noon and release it when you need it — after sunset, at peak tariff hours or when the grid goes down.

State rooftop solar top-up
Announced in TN Budget 2026-27 — awaiting government orderThe Tamil Nadu Budget 2026-27 announced a Rooftop Solar Subsidy Scheme for homes, working alongside PM Surya Ghar. It's reported to add ₹22,000 for a 3 kW system — taking total support to about ₹1 lakh.
3 kW home, once notified
₹78,000 + ₹22,000
≈ ₹1,00,000 total subsidy
- Net metering through TNPDCL
- Bi-monthly bills offset by your solar units
- We apply for the state top-up as soon as it opens
Battery storage beats peak-hour tariffs
In Tamil Nadu, units used in peak hours (6–10 AM and 6–10 PM) are billed at a higher Time-of-Day rate. A battery stores daytime solar or normal-rate energy and runs your plant through the peak.
12 AM6 AM12 PM6 PM12 AM
- Cuts peak-hour energy charges every working day
- Lowers maximum-demand (kVA) charges
- Instant backup for critical machines
- Accelerated depreciation on solar assets — ask your CA
- Zero-capex (RESCO / OPEX) options available
