Frequently Asked Questions

Straight answers to the questions we hear most.

How much does rooftop solar cost?

Cost depends on system size and site conditions, but after the PM Surya Ghar subsidy, a typical residential system's net cost is significantly lower than the sticker price — see our subsidy guide for exact CFA amounts. We provide a free, no-obligation quote after your site survey.

Do solar panels work on cloudy days?

Yes — panels still generate electricity in diffused daylight, though output is lower than on clear days. Over a full year, cloudy and rainy periods are already factored into the daily-unit estimates in our kW guide.

What maintenance does a rooftop system need?

Rooftop solar needs very little maintenance — mainly periodic panel cleaning, since dust reduces output, and an annual inspection. Solvo's O&M plans cover both.

What happens during a power cut?

Standard grid-tied systems without a battery automatically shut off during a grid outage, for safety — this is a regulatory requirement so the grid isn't fed power while utility crews are working on it. Battery backup is available as an add-on if you need power during outages.

How long do panels last?

Panels typically carry a 25-year performance warranty from the manufacturer, with output degrading only slightly — about 0.5% per year — over that period. Inverters typically carry a shorter warranty of 5–10 years and may need replacement once in the system's lifetime.

Can I install solar if I live in an apartment?

PM Surya Ghar and net-metering are designed around individual home connections. For apartments and societies, a separate group net-metering / RWA process applies — reach out and we'll walk you through it.

How is roof area related to subsidy eligibility?

There's no separate roof-area rule for the subsidy — eligibility depends on your connection type and system size (see our subsidy guide). Roof area only determines how large a system you can physically fit.

What if I want to sell my house later?

Rooftop solar is generally considered a value-add rather than a liability — the system, its remaining warranty, and lower running costs typically transfer with the property.
