The biggest advantage of a solar water heater is its low operating cost once installed, it can provide hot water with little to no electricity usage. However, it does require sufficient rooftop space and consistent sunlight, and the upfront investme...

As a rooftop solar installer and EPC company with over 5 years of experience in Kerala, having successfully completed 100+ residential solar installations and analyzed 50+ real customer electricity bills and generation reports, we have gained clear, practical insights into how different solar system sizes perform on actual Kerala homes. In this guide, we explain what homeowners can realistically expect when choosing a 1 kW, 3 kW, or 5 kW rooftop solar system, focusing on cost, energy generation, subsidy eligibility, and long-term savings.
