Frequently asked questions: TANGEDCO solar

How does TANGEDCO calculate net feed-in savings?+
Because Tamil Nadu uses bi-monthly billing with the first 100 units free, solar power generated helps keep consumers out of the punitive ₹8.00–₹11.00 per unit upper slabs, creating exceptionally fast payback.
Can non-DCR panels receive PM Surya Ghar subsidy under TANGEDCO?+
No. MNRE rules strictly mandate Domestic Content Requirement (DCR) cells and modules enrolled on ALMM List-I for any PM Surya Ghar subsidy payout.
