How Much Can You Save with Rooftop Solar in Rajasthan?
Rajasthan's high solar irradiance gives it one of the best solar ROIs in India. Find out exactly how much a 5 kW system saves you every year.
Rajasthan receives among the highest solar irradiance in India — averaging 5.5 peak sun hours per day. This makes it one of the most economically viable states for rooftop solar investment.
Understanding Solar Savings
Your solar savings depend on four main factors:
- System capacity (kW)
- Your electricity tariff (₹/unit)
- Amount of self-consumption vs. export
- Net metering arrangement with your DISCOM
Sample Calculation: 5 kW On-Grid System
Location: Jaipur, Rajasthan
Peak Sun Hours: 5.5 hours/day
System Efficiency: 85%
Monthly Generation: 5 × 5.5 × 30 × 0.85 = 701 units/month
At ₹8/unit electricity tariff:
Monthly Savings: ₹5,608
Annual Savings: ₹67,296
Typical Payback Period
A 5 kW system in Rajasthan typically costs ₹2.5 to ₹3 lakhs (after subsidy). With annual savings of ₹67,000+, the payback period is 3.7 to 4.5 years — after which you generate free electricity for 20+ years.
Net Metering Benefits
Under net metering, any excess units you export to the grid are credited to your electricity bill. At the end of the billing cycle, you only pay for the net units consumed. In months with high solar generation, many customers receive zero electricity bills.
