Why pay electricity bills when the same money can own a solar system?
Many households in Nagpur spend ₹2,000–₹2,500 every month on electricity — money that is gone forever and creates no asset. The same amount can pay the EMI of a rooftop solar system that you fully own in about 2–2.5 years, and then enjoy low bills for 25+ years.
