Why should I go solar?

Solar lowers your electricity bill from the first month, protects you from tariff hikes, raises property value and cuts emissions.

How much does rooftop solar cost?

It depends on system size, roof and components. Use our calculator for an estimate; we confirm the price after a free site visit.

What size system do I need?

Roughly 1 kW for every 120 units you use a month. Our engineer confirms the size after checking your bills and roof.

How much subsidy can I get?

Homes can get up to Rs 78,000 under PM Surya Ghar. See the details.

How long do panels last?

25 years or more, usually with a 25-year performance warranty.

Do panels work at night or on cloudy days?

They produce less on cloudy days and nothing at night. On-grid systems draw from the grid; a battery gives backup.

Will my system work during a power cut?

Standard on-grid systems switch off during outages for safety. Choose a hybrid system with batteries for backup.

Is maintenance required?

Regular cleaning and a yearly health check. Our AMC plans cover both.

How long does the whole process take?

Installation takes days; approvals and the net meter depend on your DISCOM. We give you a written timeline.

Can I get a loan?

Yes. We help you apply through partner banks and NBFCs. See finance options.

Do you service systems installed by others?

Yes. We start with an audit visit and propose an O&M plan.

Which areas do you serve?

We're based in Ahmedabad and serve all of Gujarat, with projects in 15+ states.
