Calculator assumptions: North Kerala solar irradiance (5.2 peak sun hours/day), 300 generation days/year to account for monsoon, 85% system efficiency, PM Surya Ghar subsidy rates as of 2026, EMI at 8% for 60 months.
Actual savings depend on your roof orientation, shading, exact KSEB tariff slab, monsoon cloud cover, and system components. A Techno Solar site visit gives you a precise, site-specific estimate.
How We Calculate Your Savings
Monthly Generation
System size × 5.2 peak sun hrs × 300 days ÷ 12 months × 85% efficiency = monthly units generated.
Bill Savings
Units generated (up to your consumption) × your KSEB tariff rate = monthly savings. Surplus units earn bill credits.
Net Cost & Payback
Gross cost minus PM Surya Ghar subsidy = net investment. Divide by annual savings to get payback years.
