Solar calculators
Two tools: one works out what solar would save you, the other works out how big an inverter, battery and panel your home needs. Give a name and mobile number to see the result, so we can follow up with a real price.
Solar savings calculator
Enter your bill and see the system cost, the subsidy and how long the money takes to come back.
Press the button above to see the result. You will be asked for a name and mobile number, which reaches the shop so we can send you a proper quotation.

This is an estimate, not a quotation. The real price depends on the roof, the height of the structure, cable runs and the equipment chosen.
Home requirement calculator
Count the appliances you want on backup. We will work out the inverter VA, the battery and the panel size.
Press the button above to see the result. You will be asked for a name and mobile number so we can tell you the right set and its price.
Air conditioners, pumps and fridges draw a surge when they start, so the inverter rating already carries headroom. Talk to us before you buy for a firm recommendation.
What these numbers are based on
| Assumption | Value used | Why |
|---|---|---|
| Generation | 4 units per kW per day | The year-round average for Kushinagar |
| System cost | ₹62,000/kW up to 3 kW, ₹54,000/kW above | Turnkey on-grid, local going rate |
| Subsidy | ₹30,000/kW for 2 kW, ₹18,000 for the third, capped at ₹78,000 | Current PM Surya Ghar rates |
| Tariff rise | 3 per cent a year | Used for the 25 year figure |
| Module degradation | 0.5 per cent a year | A normal warranty term |
These calculators give a working estimate. Subsidy rules and equipment prices change, and every roof is different, so a firm price only follows the site survey.
