Solar Rooftop Savings Calculator

Estimate your potential annual savings by installing a solar rooftop system.

kW
Enter the capacity of the solar panel system (e.g., 3kW, 5kW).
kWh
Estimated units (kWh) generated per day per kW of system size (depends on location, typically 3.5-5).
₹
Enter your average cost per unit (kWh) from your electricity bill.

How to Use:

  1. Enter the Solar System Size in kilowatts (kW) that you plan to install or have installed.
  2. Enter the estimated Average Daily Generation per kW in kilowatt-hours (kWh). This value depends heavily on your location's sunlight hours and panel efficiency. A typical range in India is 3.5 to 5 kWh per day per kW. Use a conservative estimate if unsure.
  3. Enter your current Average Electricity Tariff in Rupees per kWh (unit) from your electricity provider. Check your bill for the most accurate rate.
  4. Click 'Estimate Solar Savings'.
  5. The results show the estimated total annual electricity generation and the potential annual savings based on the tariff rate.

Disclaimer: This calculator provides an estimate based on average daily generation. Actual generation varies significantly due to weather, season, panel orientation, shading, maintenance, and system degradation over time. Savings also depend on net metering policies, consumption patterns, and potential changes in tariff rates. This estimate does not include installation costs, subsidies, or maintenance expenses.
