Key Factors Affecting the Price

Government Subsidy & Incentives
The Indian government continues to promote clean energy with the PM-Surya Ghar Muft Bijli Yojana and state-level programs. In 2025, homeowners can claim a subsidy of up to 40% on systems up to 3 kW and 20% on 3–10 kW systems, significantly lowering the effective price. Businesses can benefit from accelerated depreciation and GST input credits.
Residential vs. Commercial Solar Cost
- Residential systems typically range from 3–10 kW and focus on cutting monthly electricity bills.
- Commercial systems may run 20 kW and above, where economies of scale reduce the per-kW rate and provide faster ROI—ideal for factories, warehouses, and offices.
Maintenance & Lifetime Savings
Routine cleaning and an annual inspection keep panels performing at their peak. Annual maintenance usually costs ₹1,500–₹2,500 per kW, negligible compared to 25 years of free power. Over its lifetime, a 5 kW system can save more than ₹12–15 lakh in electricity bills.
