How This Solar Estimator Calculates Your Savings

All mathematical calculations follow standard MNRE engineering benchmarks and DISCOM solar net-metering regulations in Rajasthan.

📐

1. Roof Area Sizing Rule

A standard 1 kW solar power system requires approx 100 sq. ft. (9.3 sq. meters) of shadow-free rooftop space using high-efficiency 540W–580W Mono PERC / TopCon panels.

☀️

2. Generation Rule (Rajasthan)

With 300+ clear sunny days and 5.5 peak sun hours, 1 kW solar generates 4.3 to 4.5 units (kWh)/day = ~130 units/month = ~1,560 units/year in Jaipur and Rajasthan.

🏛️

3. Official Subsidy Slabs

Under PM Surya Ghar CFA guidelines: ₹30,000 for 1 kW, ₹60,000 for 2 kW, and ₹78,000 maximum for 3 kW and above credited directly via DBT to your bank.

⚡

4. JVVNL Net Metering

A bi-directional meter is installed by your DISCOM. Any surplus power generated during daytime is exported to the grid and credited against your night-time grid consumption.
