Common Questions About Solar Savings
How accurate is this calculator?
Our calculations are based on real-world data from TNEB tariffs (₹7.8 avg/unit) and Tamil Nadu's average solar irradiation (approx. 4-5 units per kW per day). While actual generation varies by season, this gives a highly realistic estimate of your potential savings.
Does this include the subsidy?
The calculator provides a "System Cost" estimate that serves as a baseline. The PM Surya Ghar subsidy (up to ₹78,000) is deducted from your final quotation, significantly improving the ROI shown here.
3kW vs 5kW: Which do I need?
If your bi-monthly bill is ₹1,500 - ₹3,500, a 3kW system is usually sufficient. If your bill is above ₹4,000 or you run multiple ACs, a 5kW system is recommended to reach a "Zero Bill" status.
What is the "Payback Period"?
The payback period is the time it takes for your electricity bill savings to cover the total cost of installation. In Cuddalore, thanks to high sunlight and subsidies, this is typically just 3 to 4 years. After that, your electricity is essentially free!
