DOMESTIC CALCULATOR

Estimate Your Solar Requirement

Enter a few basic details to get an indicative rooftop solar capacity, electricity savings and long-term savings potential.

Use the average of your recent electricity bills.
Use your approximate energy rate. ₹8/kWh is the default planning value.
Built-in planning assumptions:
• Solar generation: 101 kWh/month per kW
• Effective solar-utilisation factor: 80%
These are conservative planning assumptions for an indicative calculator and are not guarantees.

3. Potential Value of Investing the Monthly Saving
The calculated monthly saving is automatically treated as a monthly investment. Each section shows the potential value at 6%, 8%, 10%, 12% and 15% annual returns with monthly compounding.

Calculate the solar saving first.
Why the saving is lower than the full bill: the calculator first estimates solar generation, then applies an 80% effective utilisation factor. This provides a conservative allowance for system losses, timing mismatch between solar generation and household consumption, and other practical factors. It also prevents the calculator from implying that the entire electricity bill will disappear.
Important: The 6%, 8%, 10%, 12% and 15% investment figures are hypothetical return scenarios, not guaranteed returns. Actual solar savings depend on actual consumption, tariff structure, solar generation, self-consumption/export settlement, shading, system performance and applicable DISCOM rules.
This calculator is for indicative customer education and preliminary planning only. It is not an engineering design, electricity-bill simulation, quotation or investment advice. Final capacity and savings should be validated using actual 12-month consumption, site survey, sanctioned load, roof conditions and applicable DISCOM requirements.
COMMERCIAL CALCULATOR

WBSEDCL Commercial Bill & Solar Savings Calculator

Estimate your commercial electricity bill, rooftop solar savings and the potential value of investing the monthly saving over 5, 10, 15, 20 and 25 years.

1. Commercial Electricity Bill Inputs

Enter the monthly units from your commercial electricity bill.
Use the sanctioned load shown on your electricity bill.
Enter the applicable fixed charge shown on your commercial electricity bill. Example: ₹60/kVA/month.
Enter the monthly meter rent shown on your electricity bill. Example: ₹30/month.
Enter the applicable FPPCA/FAC charge per unit from your bill. Example: ₹0.25/unit.
Enter the applicable electricity duty percentage shown on your bill/tariff. Example: 6%.
Reference calculation basis:
The commercial bill structure and pre-filled planning values follow the supplied WBSEDCL Commercial Bill Calculator reference. Rates and charges are editable and should be checked against the latest applicable bill/order before use.

4. Potential Value of Investing the Monthly Saving
The calculated monthly bill saving is automatically treated as a monthly investment. Each table uses the same presentation as the Domestic Calculator and shows the potential value at 6%, 8%, 10%, 12% and 15% annual returns with monthly compounding.
Important: The 6%, 8%, 10%, 12% and 15% figures are hypothetical return scenarios, not guaranteed returns. Actual savings depend on the actual bill, tariff structure, consumption profile, solar generation, sanctioned load, self-consumption/export settlement, site conditions and applicable DISCOM rules.
This calculator is for indicative planning only. It is not an engineering design, official electricity-bill simulation, quotation or investment advice. The supplied reference states that its tariff figures are from third-party sources and should be checked against the latest bill.

    FREQUENTLY ASKED QUESTIONS

    Solar Questions, Answered

    Quick answers to common questions about rooftop solar, subsidy and savings.

    How much solar capacity do I need for my home or business?

    It depends on how much electricity you use. Our Domestic Calculator gives an indicative capacity from your average monthly bill and electricity rate. The final size is confirmed after a site survey, using your last 12 months of consumption, sanctioned load and roof conditions.

    How much government subsidy can I get?

    Under PM Surya Ghar: Muft Bijli Yojana, eligible residential rooftop systems can receive ₹30,000 for 1 kW, ₹60,000 for 2 kW and ₹78,000 for 3 kW and above. Eligibility and scheme rules can change, and we guide you through the application.

    Will my electricity bill become zero after installing solar?

    Not always. Savings depend on your consumption, tariff, solar generation, shading and the net-metering rules of your electricity distribution company (DISCOM). Our calculator uses a conservative 80% utilisation factor, so it does not assume the whole bill disappears.

    How much roof space does a rooftop solar system need?

    As a rough guide, each kW needs about 100 sq ft of shadow-free roof area. The exact requirement depends on panel size, roof shape, tilt and shading, which we check during the site assessment.

    Will solar work during a power cut?

    A standard grid-connected system switches off during a grid outage for safety reasons. If you need backup power, a hybrid system with a battery can be considered. Ask us which option suits your needs.

    Is bank financing available for rooftop solar?

    Easy financing options may be available through participating banks, subject to eligibility and each bank's terms. We can help you understand the options during your consultation.

    How much maintenance does a solar system need?

    Solar systems need little maintenance. Panels should be cleaned regularly to remove dust, and the system should be inspected from time to time to confirm it is performing as expected.

    Which areas do you serve?

    We have offices in Kolkata, Hooghly, Murshidabad and Mumbai, and serve residential and commercial customers across these locations. Contact us to check availability in your area.
