Solar Panel Savings Calculator

PM Surya Ghar Yojana provides 20% subsidy on system cost, capped at ₹78,000 for 3kW systems. 1kW = ₹30,000, 2kW = ₹60,000, 3kW = ₹78,000 (maximum). Higher capacity systems get same maximum subsidy.

Residential solar system costs ₹40,000-60,000 per kW (without subsidy). 1kW = ₹40,000-50,000, 2kW = ₹75,000-90,000, 3kW = ₹1,10,000-1,50,000. After PM Surya Ghar subsidy, costs reduce significantly.

A 3kW solar system generates approximately 300-450 units per month in India, depending on location and sunlight hours. Northern states get more generation (350-450 units), while coastal states get slightly less (300-400 units).

Solar panels typically last 25-30 years with minimal degradation (0.3-0.5% per year). Most panels come with 25-year linear power output warranty, meaning they'll still produce 80%+ power at year 25.

Yes! With 20-30% government subsidy, payback period is just 4-6 years. Over 25 years, you can save ₹3-5 lakhs after accounting for maintenance costs. Solar also increases your property value and reduces carbon footprint.

Solar panels require minimal maintenance: occasional cleaning (every 2-3 months), annual inspection of wiring and connections, and monitoring of system performance. Annual maintenance cost is approximately ₹2,000-5,000.

Yes, solar panels still generate electricity on cloudy days, but at reduced efficiency (40-60% of rated capacity). India's diverse climate means panels work year-round, with peak generation in summer and reduced output during monsoons.

Net metering allows you to export excess solar power to the grid and earn credits. Your bill is calculated based on net consumption (total drawn - exported). This maximizes your savings and provides backup during nighttime.

Yes, you can install solar without government subsidy. Many homeowners opt for this if they need faster installation or don't qualify for subsidy. The payback period without subsidy is 6-8 years, still very attractive.
