Cut Water Heating Costs by 80%
Solar Water Heater Installation in Kerala
Solar water heaters eliminate 70–80% of water heating costs. No electricity, no LPG — just free hot water from the sun, year-round. Payback in 2–4 years.
The Cost Case
Hot Water for Free — After the Initial Investment
Most Kerala homes spend ₹800–₹2,000/month on water heating — either through electric geysers or rising LPG costs. A solar water heater eliminates most of this. Payback is typically 2–4 years, after which you enjoy virtually free hot water for 15+ more years.

FAQ
Solar Water Heater FAQs
FGE Solar installs two main types: Evacuated Tube Collectors (ETC) — more efficient in low-light and cloudy conditions, ideal for Kerala — and Flat Plate Collectors (FPC) — more durable and aesthetically cleaner. We recommend ETC for most Kerala applications due to better diffused-light performance during monsoon months.
A standard 100-litre ETC system produces 100–150 litres of hot water per day — sufficient for a family of 4. For larger families or commercial needs, 200L, 300L, and 500L+ systems are available. Output varies slightly by weather, but an electric backup element kicks in on heavily cloudy days.
ANERT (Agency for Non-conventional Energy and Rural Technology) has historically run subsidised solar water heater programs for BPL households and institutional users in Kerala. Availability varies by year and scheme. FGE Solar stays updated on currently active programs and will inform you at the time of consultation.
A well-maintained solar water heater lasts 15–20 years. The collector tubes for ETC systems may need replacement every 7–10 years as individual tubes can degrade. The insulated storage tank typically lasts 15+ years. FGE Solar offers AMC packages for water heaters to ensure longevity.
