Question 1

How much can I save on my electricity bill with rooftop solar?

Accepted Answer

Rooftop solar typically offsets 80% to 95% of your annual electricity bill. For instance, a residential bill of ₹6,000/month can drop to under ₹500/month (fixed DISCOM grid charges only).

Question 2

What is the PM Surya Ghar subsidy structure for homes?

Accepted Answer

Under the Central Government PM Surya Ghar scheme: ₹30,000 per kW for 1 kWp and 2 kWp systems (total ₹60,000 for 2 kWp), and ₹18,000 for the 3rd kWp, capping out at a maximum subsidy of ₹78,000 for 3 kWp and above.

Question 3

How does net-metering work in Telangana with TSSPDCL / TSNPDCL?

Accepted Answer

A bi-directional net meter records both the energy you consume from the grid and the excess solar power exported to the grid. At the end of the monthly billing cycle, DISCOM credits your exported units against your consumption.

Question 4

Will solar panel installation damage my roof or cause leakages?

Accepted Answer

No. Sanarka Energy uses non-penetrative mounting options or chemical anchor fastening with EPDM rubber waterproofing seals. Elevated parapet structures leave full access to the terrace without touching waterproofing membranes.

Question 5

What is the difference between CAPEX and OPEX/BOOT for commercial solar?

Accepted Answer

In CAPEX, your company owns the system upfront, claims 40% Accelerated Depreciation, and achieves 2-3 year payback. In OPEX/BOOT, Sanarka/financiers invest 100% of the capital, and you simply buy power at a discounted rate (e.g. ₹4.50/kWh vs ₹9 grid rate).

Question 6

What warranties come with a Sanarka solar installation?

Accepted Answer

We provide a 25 to 30-year linear performance warranty on Tier-1 TOPCon panels, 10-year manufacturer warranty on string/hybrid inverters, 5-year installer workmanship warranty, and 3D PVsyst modeled generation benchmarks for your specific roof.
