Frequently asked questions about rooftop solar

Cost depends on system size, the panel and inverter brands, the height of the mounting structure, the cable run to the meter and whether battery storage is included. For this reason a firm written price is provided after the site survey.

Savings depend on your tariff, the units you consume and when you consume them, and the area and shading of your roof. The proposal presents savings and payback as a range and states every assumption. We do not guarantee a single figure.

For a household that stays within the free limit throughout the year, the savings are limited, and we advise accordingly. Where summer air conditioning takes consumption above the limit, a correctly sized system with net metering can bring it back within the limit. The home page explains how this works.

Yes. Public sector banks offer a PM Surya Ghar loan for home systems, and many banks and NBFCs lend for commercial solar. Interest rate, documentation and approval are determined by the lender. We provide the quotation and technical documents required.

Households that own the property, hold a domestic connection in the applicant's name and have not previously received a solar subsidy are generally eligible. Commercial connections are not covered. We currently undertake subsidy projects in Mohali, Zirakpur, Kharar and New Chandigarh, and Chandigarh and Panchkula are coming soon. See the subsidy amounts and steps.

Your electricity department replaces your meter with one that counts in both directions. Units your panels send to the grid are subtracted from units you take from it, and you are billed for the difference. It is what makes solar pay even when nobody is home during the day.

Initially, only a recent electricity bill. The net-metering and subsidy applications also require Aadhaar, proof of property ownership and the bank account to which the subsidy is to be credited. We confirm the exact list for your case before any application is filed.

We are a multi-brand company. Panels, inverters and batteries are selected to suit the roof, the budget and the compliance requirements of each project, and we quote on a customer's preferred brand where requested. See the brands we can source.

Only where power cuts are a significant concern. An on-grid system is cheaper and saves more, but it switches off when the grid goes down. A hybrid system with a battery keeps your essentials running, at a higher cost. Where an existing home inverter copes adequately, a solar battery may not be required. More on battery backup.

Most panels carry a performance warranty of 25 years or more. Their output falls slowly, by a small fraction each year, and they don't stop suddenly. The inverter is the part more likely to need repair or replacement during that time.

On a typical house the work on the roof takes a few days once the material arrives. The approvals, the net meter and the subsidy take longer, and that part runs on the department's timelines. Your proposal includes an expected timeline.

No. The structure stands on concrete footings on top of the roof slab, and any point where the roof surface is disturbed is sealed. The condition of the roof is recorded with the customer at the survey, before work begins.

Maya Green Power. We remain your point of contact after handover and manage warranty claims with the manufacturer. The handover documentation includes serial numbers, warranty cards, test readings and photographs.

Mohali (including Aerocity and IT City), Zirakpur, Kharar and New Chandigarh for all projects. In Chandigarh and Panchkula we undertake commercial rooftops, hybrid systems and larger homes that don't need the subsidy.
