Your Estimated Savings
Based on the details you entered.
Indicative figures only. Final numbers depend on site survey, shading, roof type and your current tariff slab.

Three Steps to Your Estimate
No sign-up needed to see your numbers — the form is only if you want a detailed quote.
1. Enter Your Usage
Set your average monthly bill and tariff. If you're unsure, take the figures from any recent electricity bill.
2. See Your Savings
The calculator sizes a system for your consumption and shows monthly, annual and 25-year savings instantly.
3. Get a Real Quote
Send the estimate to our team and an engineer will call you to arrange a free site survey.
How We Calculate Your Savings
There’s no guesswork here. The calculator works from your actual spend rather than a generic average, and applies the same assumptions our engineers use when sizing a real system.
- Your consumptionMonthly bill divided by your tariff gives the units you actually use — not a national average.
- System sizingWe size against peak sun hours with a 0.78 derate for inverter losses, soiling, wiring and heat, then round to the nearest half kW.
- Savings, capped honestlySavings can never exceed your bill. Oversizing beyond your usage earns export credit, not multiplied savings.
- 25-year projectionEach year compounds ~4% tariff inflation against ~0.5% panel degradation, so the long-run figure reflects both.
Assumptions Used
Verified against typical installations in our service area.
| Installed cost per kW | ₹55,000 |
| System derate factor | 0.78 |
| Roof area per kW | 80 sq ft |
| Annual panel degradation | 0.5% |
| Annual tariff inflation | 4.0% |
| CO₂ displaced per unit | 0.71 kg |
| Projection period | 25 years |
Your Estimate Already Includes Subsidy
For residential properties the calculator applies PM Surya Ghar slabs automatically. Switch the property type to Commercial or Industrial and it drops out, because the scheme doesn’t apply there.
What This Calculator Can't See
An online estimate is a starting point, not a quotation. These are the things that only a physical site survey can establish — and any of them can move the final numbers:
- Shading from water tanks, parapets, trees or neighbouring buildings
- Actual shadow-free area versus total roof area
- Roof structure, age and load-bearing capacity
- Your sanctioned load and DISCOM net-metering limits
- Existing wiring, earthing and distribution board condition
- Whether your tariff slab changes once consumption drops
Our site survey is free, takes about 40 minutes, and comes with no obligation to proceed.
Calculator FAQs
About the estimate, the subsidy and what happens after you submit.
It’s a well-founded projection, not a quotation. The generation model uses standard derating for inverter losses, soiling, wiring and heat, and savings are capped at your actual bill. What it cannot account for is shading, roof condition and your DISCOM’s specific rules — which is exactly what the free site survey establishes.
It’s the number of hours per day equivalent to full-strength sunlight (1000 W/m²). Most of Uttar Pradesh averages between 4.5 and 5.5 across the year. The 4.8 default is a reasonable middle figure — leave it unless you know your local value.
It’s printed on your electricity bill, usually as a per-unit rate or across slabs. If your bill shows several slabs, use the highest one you reach — that’s the rate solar actually displaces first.
PM Surya Ghar is a residential scheme. Commercial and industrial properties aren’t eligible, but they do qualify for 40% accelerated depreciation in the first year, which we factor into a full proposal.
Your estimate goes straight to our sales team along with your contact details. An engineer will call you — usually within one working day — to understand your requirement and arrange a free site survey. If you provided an email address, we’ll also send you a copy of the estimate for your records.
No. Your information goes to our sales team so we can prepare your quote. We don’t sell or share contact data with third parties.
