Mumbai 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.

With net metering support from BEST / Tata Power / Adani Electricity, excess solar energy you generate gets credited back to your account, maximizing your savings year-round. Current tariffs of ₹8.5–12/unit make solar highly cost-effective in Mumbai.
