Questions we hear every week.

For a home on-grid system, installed prices typically fall in a range of roughly ₹55,000–₹70,000 per kW before subsidy, depending on panel and inverter brands, structure height and roof type. Larger commercial systems cost less per kW. We give you a written range after the site survey and compare installer quotes line by line, so you only pay for what your roof needs.

A correctly sized on-grid system can offset most of the units on your bill. What remains is usually fixed charges, duties and any units you use beyond what the system generates. The exact saving depends on your consumption, your tariff slab and your DISCOM’s net-metering rules, which is why we work it out from twelve months of your actual bills.

Payback depends on system cost after subsidy, how much of your bill the system offsets and your tariff. Our calculator gives an indicative figure; after a site survey we give you a written estimate with the assumptions spelled out, so you can check them yourself.

Yes. Public-sector banks offer concessional loans for residential rooftop solar under PM Surya Ghar, and many banks and NBFCs offer solar EMIs. Rates and limits change, so we help you compare options and line up the paperwork with your subsidy application.

No. Net-metering rules usually pay a low rate for surplus units left over at the end of the settlement period, and most states cap system size relative to your sanctioned load. Oversizing adds cost without adding much saving. We size to your actual consumption.

For homes, central financial assistance is ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000 for 3 kW and above. Housing societies can get ₹18,000 per kW for common facilities, up to 500 kW. Some states add a top-up. Amounts change, so we verify on the national portal before you apply.

The subsidy is paid directly into your bank account after the net meter is installed, the DISCOM inspects the system and the commissioning report is uploaded. Timelines vary by DISCOM and season. We track every stage and chase follow-ups for you, so the application never stalls.

Broadly: an Indian household with its own roof suitable for solar, a valid electricity connection in the applicant’s name, and no other central solar subsidy already availed for that connection. The system must be installed by a registered vendor and use eligible (domestically manufactured) panels. We check eligibility before you spend anything.

Yes. Group housing societies and RWAs can claim central financial assistance of ₹18,000 per kW for systems that power common facilities, up to 500 kW. Committee approvals and documents differ from individual homes, and we handle that paperwork too.

PM Surya Ghar central assistance is for residential consumers. Commercial and industrial systems generally don’t get a capital subsidy, but they can benefit from accelerated depreciation and lower cost per unit. Confirm the tax treatment with your chartered accountant.

Yes, at lower output. Panels generate from diffuse daylight on cloudy days, typically a fraction of a clear day. Our yearly estimates already account for monsoon months, and with net-metering the extra units you export in sunny months offset the cloudy ones.

Very little. Clean the panels with plain water every 2–4 weeks (more often in dusty areas), keep an eye on the inverter display and have a yearly health check of wiring, earthing and structure. Our yearly check is built into the consultancy.

Reputable panels usually carry a 25-year performance warranty plus a separate product warranty, and inverters typically 5–10 years. We read the warranty documents with you and make sure they are registered in your name at handover.

Not when it’s done properly. We specify the right structure for your roof (RCC, tin shed or tile), make sure anchors are sealed and waterproofed, and keep drainage paths clear. Checking this on site is part of our installation supervision.

A standard on-grid system shuts down when the grid fails. This is a safety requirement. If you need backup, a hybrid system with a battery can keep chosen circuits running. We size the battery for your essential loads only, so you don’t pay for capacity you won’t use.

Plan for about 100 sq ft of shade-free area per kW. A 3 kW home system needs roughly 300 sq ft of usable roof, after allowing for tanks, stair rooms and walkways. Elevated structures can help on crowded terraces.

We charge for consultancy: design, quote comparison, subsidy filing and installation supervision. Because we don’t earn more when you buy a bigger system or a particular brand, our advice stays on your side. We explain our fee in writing before you commit.

Yes. We review your electricity bill, discuss your goals and tell you honestly whether solar makes sense for you. There is no obligation to go further.

A vetted installer that you choose after we compare quotes side by side. We specify the design, check the installer’s work on site against it and close the snag list before sign-off.

Yes. Our audit and O&M service tests existing systems, finds the cause of under-performance (shade, soiling, wiring, inverter settings, faulty modules) and tells you what to fix and whom to hold to it.

We work across our home region and nearby districts. Share your location when you book and we’ll confirm. Site surveys need a visit, but the first bill review can happen over WhatsApp.
