Frequently Asked Questions

☀️ Solar Karnataka FAQ

Rooftop solar can be financially attractive for households and businesses with regular electricity consumption and suitable roof space. Actual economics depend on system cost, electricity tariff, generation, consumption pattern, subsidy eligibility and financing.
There is no single system size for every ₹5,000 bill because the effective tariff and actual electricity consumption differ between consumers. Use the Bill → Solar Size Calculator above and replace the default tariff with the effective rate from your electricity bill.
The central CFA structure provides ₹30,000 per kW for the first 2 kW and ₹18,000 for the additional 1 kW, with a maximum central CFA of ₹78,000 for an individual residential system under the applicable scheme structure. Eligibility and processing are subject to the current scheme rules and portal process.
200 LPD is a practical starting point for many four-person households with moderate hot-water consumption. Actual sizing should be based on litres used per day, bathing habits, number of bathrooms and desired hot-water reserve.
A solar water heater can greatly reduce electricity required for water heating, but electricity may still be required for backup heating, pumps or other components depending on the system.
Yes. A rooftop solar system can supply electricity for EV charging. The practical benefit depends on the vehicle’s energy consumption, driving distance, solar generation, charging schedule and whether charging occurs while solar generation is available.

☀️ Calculate Before You Buy

Don’t choose a solar system, water heater or EV charging setup from a sales quotation alone. Start with your electricity consumption, actual hot-water requirement and expected usage.
