Best Solar Water Heater in Bihar
ETC & FPC solar water heaters, heat pumps and rooftop solar by Kamal Solar — BIS certified, MNRE approved, free site survey and fast installation across Patna, Gaya, Bhagalpur, Muzaffarpur, Purnia, Darbhanga and every major district.
Solar Water Heaters Built for Bihar's Water & Weather
Kamal Solar supplies and installs solar water heating systems across Bihar — from Patna, Gaya, Bhagalpur, Muzaffarpur, Purnia, Darbhanga and every major district. With 270–290 days of sunshine per year and peak solar irradiance of 4.5–5.2 kWh/m²/day, Bihar offers excellent conditions for solar water heating: a correctly sized system delivers hot water most of the year, with minimal backup from any electrical element.
Bihar's Gangetic plain alluvial groundwater is generally soft to moderate TDS; SS tanks are suitable for most areas, with GL recommended for borewell users in select districts with higher mineral content. That's why our team assesses your water source during the free site survey before recommending any model — whether that's an ETC with GL tank, FPC with SS tank, or a water softener pairing. Every recommendation comes in writing before you confirm the order.
Every unit you heat with solar is a unit you don't buy from NBPDCL / SBPDCL at ₹6.10–7.45 per unit (domestic slab). A typical 200 LPD ETC system pays for itself in under 3 years in Bihar's climate and lasts 15+ years with basic annual maintenance.

What is the price of a solar water heater in Bihar?
Price depends on capacity (100–500 LPD), collector type (ETC or FPC) and tank material (GL or SS) — which we recommend based on your water quality. We provide a transparent written quote after a free site survey. Call or WhatsApp for today's best price anywhere in Bihar.
Which solar water heater tank — SS or GL — is right for Bihar?
Bihar's Gangetic alluvial groundwater is generally soft-to-moderate TDS, making SS tanks suitable for most of the state. However, some borewell users in Gaya, Aurangabad and southern Bihar districts have harder groundwater where GL tanks are the safer choice. Our team checks your water source during the free site survey before recommending a model.
How much electricity does a solar water heater save in Bihar?
A 200 LPD ETC system saves roughly 1,500–2,200 units per year for a family of four. At NBPDCL / SBPDCL domestic tariffs of ₹6.10–7.45 per unit (domestic slab), that is a saving of ₹7,000–11,000 every year — payback typically in 3–4 years.
Is there a government subsidy for solar water heaters in Bihar?
BREDA (Bihar Renewable Energy Development Agency) periodically announces subsidies and incentives for MNRE-approved solar water heaters. All Kamal Solar products are BIS certified and MNRE approved, making them eligible for such schemes. Contact us for the latest subsidy status at the time of your purchase.
Do you provide installation and after-sales service across all districts of Bihar?
Yes. We install and service across all major districts of Bihar — from Patna, Gaya, Bhagalpur, Muzaffarpur and beyond. We work through our factory-trained dealer network to ensure service visits within 24–48 hours of a complaint.
What warranty does Kamal Solar provide in Bihar?
Tanks carry a 5-year warranty (GL or SS as per model), evacuated tubes and collectors 2–5 years, and heat pumps 2–5 years compressor warranty — all backed by Kamal Solar's on-ground dealer service network across Bihar.
