Solar panels — types, brands and efficiency
1 discussion · answered by India's solar community
Panel choice is where most quotes differ. This topic covers technologies (mono PERC, TOPCon, HJT, bifacial), real-world efficiency and degradation, which brands are on the ALMM list the subsidy requires, and how to read a warranty.
Ask with the quote in hand — wattage, brand, price per watt and your city — and you will get answers from people who have compared the same ones.
Questions this topic answers
- TOPCon or mono PERC for a home roof in 2026?
- How much do panels degrade per year, really?
- Is this brand ALMM-listed, and does that matter for the subsidy?
