How a Hyderabad household can decide on rooftop solar

Start with the bill, not with a panel brand. The units you buy each month, and the slab you fall into with TGSPDCL or TSSPDCL, decide whether a roof system is worth a survey.

Then look at the roof in the afternoon, not at noon on a brochure. Shade from a tank, a neighbour’s floor or a tree removes more generation than a datasheet can see. A useful survey marks that shade. It does not assume a clear south-facing rectangle.

PM Surya Ghar can reduce the cost for an eligible home, up to ₹78,000 of central assistance, but only after the national portal, the DISCOM and commissioning line up. Treat the subsidy as a prompt to check eligibility, not as money already approved.

If an electric vehicle is already in the plan, say so before the inverter is chosen. Overnight charging and evening backup pull the design in a different direction from a simple grid-tied plant.

A serious proposal names the capacity, the equipment, what is included in installation, and what still depends on the utility. Anything that promises a fixed payback without those details is a guess.
