How the Solar Calculator Estimates Your Electricity Bill Savings


Delhi receives ample sunlight throughout the year, making solar power a reliable energy source. The Fayda365 Solar Calculator uses local solar radiation data to estimate how much electricity your system will generate. This translates into:


  • Reduced electricity bills by offsetting grid consumption

  • Potential earnings from net metering if your system produces excess power

  • Long-term savings as solar panels typically last 25 years or more with minimal maintenance


For example, a typical 3 kW rooftop solar system in Delhi can generate around 4,200 to 4,500 kWh annually. If your electricity rate is ₹8 per kWh, this means savings of approximately ₹33,600 to ₹36000 every year.


Government Subsidies and Benefits in Delhi


The Indian government encourages solar adoption through subsidies and incentives. Delhi residents can benefit from:
