Electricity Bills down from ₹2,800 to under ₹900 a month!
Amit Verma
Rated 4.8 On Google with 500+

TerraRex Energy made switching to solar unbelievably easy. I didn't have the full amount upfront, so their EMI plan was a lifesaver. They handled the subsidy, paperwork, and installation without me running around even once. Now my bill has dropped from ₹2,800 to under ₹900 a month.
The best part about TerraRex is their support. Even after installation, the team keeps checking if everything is working properly. One of my panels needed adjustment during the rains—they fixed it the same day. Clean work, clean energy, zero hassle.
I was confused between 2kW and 3kW, but the team did a proper site survey and explained my actual load. They also showed how much subsidy I'd get and helped me apply on the spot. The app-based monitoring is great—I can see production and savings any time.
