Savings depend on your system size, location, and energy usage, but solar typically delivers significant reductions in electricity bills and attractive long-term returns on investment. In India, with government incentives like the PM Surya Ghar Muft Bijli Yojana, homeowners can receive subsidies of up to approximately ₹78,000 for 3 kW systems (and proportionally for other sizes), which can reduce upfront costs by around 30–45%.
A typical 5 kW Industrial rooftop system in India can save roughly ₹42,000 – ₹65,000 per year in bill reductions depending on your tariff and usage, with payback (ROI) often occurring within 3.5–5 years after subsidies. After the system pays for itself, electricity generated is essentially free for the remaining 20+ years, potentially saving you ₹15–20 lakh+ over the lifetime of the panels.
Overall, most homeowners see electricity bill reductions of 70–95%, and when combined with net metering credits, solar can greatly lower their energy costs while giving excellent return on investment.
