Solar Panel Installers in Guwahati

Solar Energy for Guwahati Homes & Businesses

Guwahati is experiencing rapid solar adoption due to favorable climate conditions and strong government incentives. The PM Surya Ghar Muft Bijli Yojana makes it more affordable than ever to switch to rooftop solar. Most 2–3 BHK homes benefit from a 3–5 kW solar system, which can reduce electricity bills by ₹2,000–3,000 monthly and pay for itself in just 3–4 years.

With net metering support from APDCL (Assam Power Distribution Company), excess solar energy you generate gets credited back to your account, maximizing your savings year-round. Current tariffs of ₹6–8/unit make solar highly cost-effective in Guwahati.
