About This Calculator

How accurate is this solar savings estimate?

This calculator gives you a reliable ballpark figure based on average KSEB tariff rates, Kerala's solar irradiance data, and current PM Surya Ghar subsidy slabs. It is typically accurate within ±10–15% of the actual quote. For a precise number, our engineer will visit your site free of charge and assess roof area, shading, orientation, and local grid conditions.

Does the subsidy amount vary by district?

The PM Surya Ghar subsidy itself is the same across all Kerala districts — ₹30,000 per kW for the first 2kW and ₹18,000 per kW for the third kW (capped at 3kW), giving a maximum of ₹78,000. However, solar output and savings estimates may vary slightly by district due to differences in average sun hours and local KSEB tariff slabs.

Why does the calculator ask for roof type and property type?

Roof type affects the mounting system and installation cost — sloped roofs typically use hook-and-rail systems while flat roofs need angled ballast frames. Property type determines subsidy eligibility: PM Surya Ghar subsidy applies to residential connections only. Commercial properties have different KSEB tariff slabs which changes the savings calculation. Both factors help us give you the most relevant estimate.
