Anything else
we should cover?
How long does the installation process take?
Once you book a free site visit, our team completes the 3D design and documentation within 2–3 days. Actual rooftop installation typically takes just 1 day. From booking to a live, generating system, most customers are up and running within a week.
Will TerraRex handle the government subsidy process?
Yes, completely. We manage the entire PM Surya Ghar Muft Bijli Yojana subsidy process on your behalf — from registration on the national portal to coordinating with your DISCOM and ensuring the subsidy amount is credited to your account. You don't need to visit any office.
What financing and EMI options are available?
We offer flexible EMI plans starting from as low as ₹180/month, with zero down payment options available. In many cases, your monthly EMI is lower than your current electricity bill from day one, making the switch completely cost-neutral.
