The real cost of waiting one more year to install solar

The most common thing we hear at surveys is some version of 'we have been thinking about this for two years.' Thinking is free, but waiting is not. Here is what postponing actually costs a typical Kerala home.

The bills you keep paying

A household with a ₹3,000 monthly bill hands KSEB ₹36,000 in a year. A correctly sized system removes most of that. Wait a year and that money is simply gone, roughly half the price of a 3 kW system after subsidy.

Tariffs move in one direction

KSEB tariffs are revised upward, not downward. Every revision makes the electricity you buy more expensive and the electricity your roof produces more valuable. The payback period of a system installed today shortens with every hike.

Subsidy schemes do not wait

PM Surya Ghar currently pays up to ₹78,000 on residential systems of 3 kW and above. Central schemes have budgets and end dates, and earlier state schemes have closed before. The subsidy available today is the only one you can actually count on.

None of this means buying in a panic. It means the free survey is worth doing this month, not next year. The numbers for your specific roof and bill will make the decision for you.
