How installing solar can save lakhs of rupees?

Now that you know the correct answers, it’s natural that you might have developed the curiosity to understand how a solar system can help save lakhs and lakhs of rupees. 

If yes, this bonus section will delight you. Let’s talk numbers!

  • – Price of a 3 KW solar system = ₹1,80,000 to ₹2,40,000
  • – Subsidy on a 3 KW solar system = ₹43,764
  • – Price of a 3 KW system after subsidy = ₹1,36,236 to ₹1,96,236
  • – Your yearly power consumption is about 4200 units
  • – Approx yearly units a 3 KW system produces are also about 4200
  • – Let’s assume, the tariff/ unit you pay = ₹8

According to the numbers we’ve used for reference, the approx yearly bill you must be paying without a 3 KW solar system would be close to ₹33,600 (4200 x 8)

When you install a 3 KW solar system, it will generate 4200 units of electricity. Since you’ll get these units for free, your yearly savings would be about ₹33,600.

Since branded solar systems last for a minimum of 25 years, your savings in 25 years will be minimum of ₹8,40,000 (₹33,600 x 25)

We said that ₹8,40,000 would be your minimum savings because electricity tariffs increase by 3-5% yearly.

Hence, the actual savings will be much higher than ₹8,40,000.
