Common-area solar only powers the lift, lobby and pumps, so your personal bill barely changes. Protostar covers the full rooftop and uses the patented SPDU to give every individual flat, shop and office its own metered share of solar power. The savings show up on your own electricity bill, not just the society's.

Nothing changes for you. The SPDU automatically switches your home to the normal grid supply whenever solar is not available, with no interruption. Solar first, grid as backup, completely automatic.

Each unit is allotted a fixed solar quota, decided together with the society at design time and enforced by the SPDU hardware. Every unit's share is separately metered, and you can see your balance and usage live on the Nova app. No neighbour can use your share.

Cost depends on your roof size, number of units and structure type, so we start with a free site visit and give the society a detailed quotation. Rooftop solar in Maharashtra typically pays for itself in about 3 to 5 years through bill savings, and the panels keep producing for 25 years.

Solar installation is a society decision, usually passed in a general body meeting per your society's byelaws. We support the committee with presentations, savings workings and documentation to help members decide, and we handle DISCOM approvals and paperwork after that.

Housing societies can avail central subsidies for shared rooftop solar under the PM Surya Ghar scheme, subject to current scheme rules and capacity limits. We assess eligibility during the site visit and handle the application process for you.

We do. Our annual maintenance contract covers professional panel cleaning, performance monitoring and prompt issue resolution. Dust alone can cut generation by up to 25 percent, so maintenance is what protects your savings.

Yes. The SPDU distributes solar to any mix of units that share one roof: flats, shops, offices, clinics or an entire commercial building with multiple tenants.

No. All work happens on the rooftop and in the building's meter room. Nobody enters your home, and a typical retrofit is completed in about 3 months including approvals.
