FAQs
What is TOPCon technology and why is it better?
TOPCon (Tunnel Oxide Passivated Contact) is next-generation cell technology that delivers higher efficiency, lower degradation, and superior performance in low-light and high-temperature conditions. 600W and 635W DCR variants use N-Type G12R cells with 16BB busbars.
What does DCR mean and why does it matter?
DCR (Domestic Content Requirement) means cells are made in India — mandatory for PM Surya Ghar Muft Bijli Yojana subsidy eligibility. 600W and 635W TOPCon DCR qualify for central subsidy of ₹78,000 plus additional state subsidy.
Should I choose 600W or 635W for my home?
Both deliver 30-year warranty and 22–23%+ efficiency. 600W (2278 x 1134 x 30 mm, 32 kg) suits standard residential rooftops. 635W (2382 x 1134 x 30 mm, 34 kg) delivers more power per panel for higher kW systems or limited roof areas. Your dealer will size the array to your needs.
What does up to 22–23%+ module efficiency mean?
The panel converts 22–23% of incoming sunlight into electricity. Higher efficiency = more power from the same roof area. Critical in urban settings where rooftop space is limited — fewer 600W/635W TOPCon panels needed for the same output.
What is the warranty on 600W/635W TOPCon DCR?
Up to 30-year performance warranty — the longest in the Eastman range. N-Type TOPCon cells degrade slower than P-Type, supporting higher long-term energy yield. BIS and ALMM certified for full subsidy eligibility.
How do I apply for PM Surya Ghar subsidy with 600W/635W TOPCon DCR?
Register on the National Portal (pmsuryaghar.gov.in), pick an empanelled vendor, and install with a grid-tie inverter. Subsidy is credited to your bank account post-inspection. Your Eastman dealer assists with the full registration and installation process.
How many 600W/635W TOPCon DCR panels do I need?
A 3kW system needs 5 panels of 600W (or 5 of 635W) generating 12–15 units/day and qualifies for full PM Surya Ghar subsidy. A 5kW system needs 8–9 panels. Higher wattage = fewer panels = less roof area and mounting cost.
What subsidy can I get with 600W/635W TOPCon DCR?
Central subsidy under PM Surya Ghar: ₹78,000 (for 3kW+ systems) plus additional state subsidy where applicable. DCR certification is mandatory for subsidy — Non-DCR panels do not qualify.
Are 600W/635W TOPCon DCR panels suitable for extreme Indian conditions?
Yes — PID-resistant construction, durable glass and frame, and corrosion resistance ensure consistent performance through heat, humidity, monsoon, and coastal exposure. Strong mechanical load rating handles high winds and physical stress.
How do I maintain 600W/635W TOPCon DCR panels?
Clean every 2–4 weeks with water and a soft cloth — especially in dusty or summer months. Avoid abrasive cleaners. Annual professional inspection via Eastman Assure (1800-419-8610) checks connections, mounting, and panel surface condition.
