As energy bills rise and people shift towards renewable sources, solar water heaters have become a popular and eco-friendly choice in Indian households. The best part? The Indian Government is offering subsidies to promote solar water heater installations. If you’re planning to install one, here’s everything you need to know—from cost and working to subsidy eligibility.
What is a Solar Water Heater & How Does it Work?
A solar water heater uses the sun’s energy to heat water. It consists of solar collectors (usually installed on the roof) that absorb solar radiation and convert it into heat. This heat is then transferred to water stored in a tank, giving you hot water without using electricity or gas.
Government Subsidy on Solar Water Heaters
The Ministry of New and Renewable Energy (MNRE), along with various state governments, provides subsidies to encourage adoption of solar appliances. Typically, the subsidy can be up to 30%, and in some states, it may go even higherb up to 50% for residential users.
Required Documents to Claim Subsidy:
- Aadhaar Card or Identity Proof
- Address Proof
- Latest Electricity Bill
- Installation Invoice and Photos
