Complete Guide to Solar ROI Calculator India
Understanding the return on investment (ROI) for solar panels is crucial before making this significant financial decision. Our solar ROI calculator India helps you determine exactly how much you'll save over 25 years, when you'll break even, and what government subsidies you qualify for.
Why Use a Solar ROI Calculator?
Solar panel installation is a 25-year investment. Our calculator eliminates guesswork by providing accurate projections based on your actual electricity consumption, roof area, location, and current market rates. Unlike generic calculators, we factor in India-specific variables like MNRE subsidies, state net metering policies, and regional electricity tariffs.

Frequently Asked Questions About Solar ROI
Q What is a good ROI for solar panels in India?
A good solar ROI in India typically ranges from 15-25% annually. Residential systems with subsidy see payback in 3-5 years, while commercial systems achieve 2-4 year payback due to higher tariffs and tax benefits. Over 25 years, expect 300-500% total returns depending on location, system quality, and electricity tariff escalation.
Q How accurate are solar calculator results?
Our calculator provides 85-90% accuracy for most cases. Variations occur due to site-specific factors like shading, roof orientation, actual panel degradation, and local electricity tariff changes. For precise estimates, request a free site assessment where we measure exact parameters and provide guaranteed performance projections.
Q Does the calculator include government subsidy?
Yes. For residential systems, the calculator automatically applies MNRE central subsidy: 40% (₹18,000/kW) for first 3kW and 20% (₹9,000/kW) for 3-10kW, with maximum ₹78,000 for 3kW systems. Commercial and industrial systems don't receive capital subsidy but can claim 40% accelerated depreciation which our calculator factors into ROI calculations.
Q What is the typical payback period for solar in India?
Residential: 3-5 years with subsidy, 5-7 years without. Commercial: 3-4 years. Industrial: 2-3 years. Factors affecting payback include electricity tariff (higher = faster), system size (larger = economies of scale), location solar irradiation, and financing method. States with high tariffs like Maharashtra, Gujarat, and Tamil Nadu see fastest payback.
Q How does net metering affect my solar ROI?
Net metering significantly improves ROI by crediting you for excess solar generation exported to the grid. In states with annual rollover (Gujarat, Haryana), you can bank credits for 12 months. Quarterly settlement states (Maharashtra) limit banking to 3 months. Without net metering, you can only offset daytime consumption, reducing overall savings by 30-40%.
Q Should I include battery storage in my solar system?
For grid-connected systems with net metering, batteries typically reduce ROI due to high upfront cost (₹90,000-1,20,000 per 5kWh) and replacement after 5-7 years. Batteries make sense only if: (1) frequent power cuts, (2) time-of-use tariffs with expensive peak hours, (3) poor net metering policy, or (4) complete grid independence is priority over economics. For most cases, net metering is more economical than batteries.
Q How do I use the solar ROI calculator?
Simply enter your: (1) property type (residential/commercial/industrial), (2) monthly electricity bill or consumption, (3) available roof area, (4) location/state, (5) timeline preference. The calculator then recommends optimal system size, shows total cost breakdown, subsidy/tax benefits, payback period, and 25-year savings. You can also toggle add-ons like monitoring, insurance, and maintenance plans to see their impact on ROI.
