Frequently Asked Questions

You are eligible if you are an Indian residential property owner with: (1) an active DISCOM electricity connection in your name, (2) a shadow-free rooftop of at least 100 sq. ft. per kW of capacity, and (3) no prior solar subsidy claimed at the same address. Government, commercial and industrial consumers are not eligible for this specific residential scheme but have other incentives available (Accelerated Depreciation, AD).

Andhra Pradesh: Up to ₹18,000/kW additional state-level support for residential rooftops. SC/ST beneficiaries get up to 100% subsidy; other eligible categories up to 40%. Net-metering through APEPDCL & APSPDCL with no cross-subsidy or wheeling charges.

Telangana: 40% of benchmark cost for systems 1–3 kW, plus 20% for capacity above 3 kW up to 10 kW. Net-metering through TGSPDCL/TGNPDCL.

We layer the central PM Surya Ghar CFA with applicable state subsidies — and do all the paperwork for you.

For a typical 3 kW residential on-grid system in AP or Telangana after central subsidy: payback is usually 3.5 to 5 years. The system continues generating for another 20+ years, giving you essentially free electricity for two decades. Commercial & industrial systems often pay back in 3 to 4 years after factoring in Accelerated Depreciation tax benefits.

Net-metering is a billing mechanism where a bi-directional meter measures both the electricity you consume from the grid and the surplus solar power you export back. At the end of each billing cycle, the DISCOM nets the two and you only pay for (or get credited for) the difference. We handle the entire net-metering application with your DISCOM (APEPDCL, APSPDCL, TGSPDCL or TGNPDCL) — including the bi-directional meter installation. The maximum net-metering capacity is 1 MWp per consumer.

On-grid (grid-tied): cheapest, exports surplus to the grid via net-metering, eligible for PM Surya Ghar subsidy — but stops working during a power cut. Best for cities with reliable supply.

Off-grid (battery-only): independent of the grid, runs entirely on solar + a battery bank. Higher cost. Best for villages, farms or remote sites without a reliable connection.

Hybrid (solar + battery + grid): rides through power cuts seamlessly, can still export surplus where rules allow. Higher upfront cost but best of both worlds — recommended for areas with frequent outages.

Roughly 100 sq. ft. of shadow-free roof per 1 kW of capacity. So a 3 kW system needs ~300 sq. ft., and a 10 kW system about 1,000 sq. ft. The roof should be free of major shadows between 9 AM and 4 PM. We assess this during the free site survey using a shadow-analysis tool.

The Tata Power Solar modules we install carry a 25-year linear performance warranty (guaranteed to produce at least 80–85% of their rated output even at year 25) and a 12-year product warranty. String inverters typically come with a 5-year warranty (extendable to 10–25 years). Mounting structures are galvanised for 25+ years of corrosion resistance.

Yes — panels still generate, just at reduced output. A heavy monsoon day might produce 20–40% of a clear sunny day. Annual generation estimates already account for cloudy days, monsoon, and dust. Coastal AP and Telangana average around 4.5–5.5 kWh per kW per day annualised — the math works in your favour.

PM-KUSUM is a central scheme for solarising agriculture. Component A funds grid-connected solar plants (500 kW – 2 MW) on barren / fallow land. Component B subsidises stand-alone solar pumps (1 HP – 10 HP) — up to 60% central + state subsidy, the farmer pays only ~40%. Component C funds the solarisation of existing grid-connected agricultural pumps. We handle Component B installations end-to-end.

Tata Power Solar is India's #1 rooftop solar EPC with 1900+ MW of cumulative installations, 1.5 lakh+ rooftops solarised, presence in 700+ cities, and a 25-year module warranty backed by the Tata trust mark. As an associate channel, every kilowatt we install uses Tier-1, made-in-India panels with lifetime service support across India and easy financing through Tata Power's bank tie-ups (e.g., Bank of India).

Yes. Most public-sector and several private banks offer rooftop solar loans at concessional rates under the PM Surya Ghar scheme — typically around 6.75% p.a. for systems up to 3 kW. We help you with documentation and connect you with our financing partners (including Tata Power's tie-up with Bank of India) for low-EMI installation.

Site survey to commissioning typically takes 3 – 6 weeks. The on-site installation itself is usually 2–4 days for a residential system. Most of the timeline is DISCOM net-metering paperwork and the bi-directional meter changeover, which we expedite as much as the utility allows.

Yes. Every system we install includes 1 year of free cleaning and AMC, with optional annual extensions starting from ₹500 / kW / year. AMC covers 4 quarterly cleanings, inverter health checks, performance reports and remote monitoring through an app. Dirty panels can lose 15–25% of generation — keep them clean and the system pays you back faster.

Yes. We started as electrical contractors and continue to do full electrical work — wiring, panel upgrades, lighting, generator & UPS installation, surge protection, EV chargers and industrial automation — even if you are not yet adding solar. Our solar customers get a single accountable team for both trades.

Sometimes. Older homes may need a switchboard upgrade with adequate breakers and proper earthing before a solar inverter and net-meter can be safely added. Our electrical & solar engineers assess this during the site survey and quote any upgrades transparently along with the solar package.
