Residential Rooftop Solar

Rooftop Solar Built Around Your Home's Electricity Use.

Your home does not need a generic "solar kit" pushed out of a catalog. It needs a system sized around your actual unit consumption, available roof space, and local utility net-metering regulations.

Common Questions Answered

Can Solar Work for Your Home?

Before purchasing solar panels, every homeowner should have clarity on these fundamental technical factors.

How Much Solar Capacity Do I Need?

Most 2 to 4 BHK urban households in Maharashtra require between 3 kW and 6 kW. Sizing is governed by dividing your monthly unit consumption by 120–130 units (the average monthly yield of 1 kWp in Western India).

What Roof Area Is Required?

You need approximately 80 to 100 square feet of shadow-free roof area per kilowatt of solar. For a 3 kW system, an unshaded terrace area of ~250–300 sq. ft. is sufficient.

What Is Net Metering?

A bi-directional electric meter replaces your existing meter. When your solar generates more power than your home uses during the day, the excess is sent to the grid for electricity credit against your night-time consumption.

Do I Need Battery Storage?

If your neighborhood experiences reliable grid power, an On-Grid system delivers maximum financial savings without battery replacement costs. If power cuts are regular, a Hybrid system with a battery bank keeps critical lights and appliances running.

Will Installation Damage My Roof?

No. For flat concrete terraces, we use elevated hot-dip galvanized structures with precast concrete counterweight blocks or chemical anchors with UV-grade waterproof sealant to preserve the roof membrane completely.

What Happens After Installation?

iSolar sets up remote IoT cloud monitoring on your smartphone so you can see daily power generation in real-time. We handle DISCOM commissioning and provide lifetime maintenance support.

Recommended Architecture: On-Grid Solar System

Direct grid-tied solar is the most cost-effective solution for properties with a stable utility supply and net-metering.

This is a preliminary sizing estimate, not a final engineering proposal. Final sizing, generation yield, and commercial ROI depend on a formal site survey, sanctioned load, shadow analysis, roof structure, and local utility DISCOM approvals.
