Estimate the system size, savings potential, and space needs for your solar project before moving into a detailed feasibility review.
The calculator is meant to speed up early-stage planning. It translates your current electricity spend into a rough solar recommendation so you can gauge system size, savings, and payback before the site-specific design phase begins.
It is especially useful when you want a grounded first conversation with our team rather than starting from a blank page.
The calculator helps you estimate the size of system your current bill may support before a formal site review begins.
Projected monthly and yearly savings make it easier to discuss project value with internal stakeholders or family decision makers.
Once you understand the rough sizing and savings range, it becomes much easier to move into a detailed consultation.

Our engineers analyze your roof using high-res 3D satellite shadow mapping.
Enter your monthly bill to estimate your current electricity usage profile.
Adjust the unit rate and optional roof area to refine the calculation.
Review the recommended system size, savings estimate, and space requirement.
Use the result as a starting point for a site-specific feasibility discussion with our team.
A homeowner can use the calculator to understand whether a rooftop system fits available space and whether the monthly bill justifies the investment.
A business team can compare likely savings and payback before requesting a site survey for a larger rooftop installation.
Operations teams can use the tool as an initial screening step before moving into a more detailed technical and financial review.
The calculator uses regional solar insolation rates (averaging 4.5–5.5 peak sun hours) and state-specific electricity tariff bands to provide a dependable preliminary estimate of required kW, monthly savings, and roof area.
The calculator outlines the benchmark system cost. Central subsidies of up to ₹78,000 are available for residential rooftop systems up to 3 kW under PM Surya Ghar, which further reduces net capital expense.
