Solar for your home. Pay only the fixed charges.
A grid-tied rooftop system sized to your actual consumption, designed by engineers, filed for the PM Surya Ghar subsidy by us, and net-metered with KSEB. Add a battery for outages and an EV charger when you're ready.
- PM Surya Ghar subsidy up to ₹78,000
- KSEB net-metering handled
- ALMM / DCR compliant modules
- Hybrid & EV add-ons
*Energy charges reduced to zero where rooftop space allows a system sized to full consumption; KSEB fixed charges continue to apply.

Built around how you actually use power
High KSEB bills
Bimonthly bills that keep climbing, especially with AC and induction cooking.
Outage-weary households
Monsoon power cuts: a hybrid system keeps lights, fans, fridge and router on.
EV owners and buyers
Charge from your own roof for about ₹1 per km.
From sunlight to a smaller bill
- 1
Roof to meter
Panels generate during the day; the inverter feeds your home first and exports surplus to KSEB under net metering.
- 2
Credits balance the night
Surplus units are credited against what you draw at night and in monsoon months.
- 3
You pay the fixed charges
With a system sized to full consumption, energy charges go to zero; KSEB fixed charges continue.

Solar for homes: common questions
How big a system do I need?
Roughly one kW for every 120–130 units you use per month, if you have the roof area (about 90 sq ft per kW). The calculator above does the arithmetic and flags when your roof is the limit.
What does the PM Surya Ghar subsidy cover?
₹30,000 per kW for the first 2 kW and ₹18,000 for the 3rd kW, capped at ₹78,000 for 3 kW and above, on grid-connected residential rooftop systems. Batteries and EV chargers are outside the central subsidy.
Do I need KSEB approval?
Yes — and we manage it: the feasibility application, inspection and bi-directional meter. Scout pre-checks your transformer and connected load so there are no surprises.
How long does it take?
About 30 days from consultation to switch-on. Subsidy DBT follows after DISCOM inspection and commissioning.
