Frequently Asked Questions
Which solar panel type is best for homes in UP?
For most homes in UP, Mono PERC 540W panels offer the best value — proven technology, 21% efficiency, and affordable at ₹28-32/Wp. If budget allows, N-Type TOPCon panels (₹30-35/Wp) provide better heat performance and lower degradation, ideal for UP summers.
What is the difference between Mono PERC and TOPCon panels?
Mono PERC panels use older P-type silicon (21% efficiency, 0.55%/yr degradation), while TOPCon uses N-type silicon (22-23% efficiency, 0.40%/yr degradation). TOPCon handles heat better (-0.30%/°C vs -0.35%/°C) and comes with 30-year warranty vs 25 years, but costs 10-15% more.
Are polycrystalline panels still worth buying in 2026?
No, polycrystalline panels are being phased out. At 16-18% efficiency, they need 25-30% more roof area than Mono PERC for the same output. The small cost saving (₹22-26/Wp vs ₹28-32/Wp) doesn't justify the lower performance and higher degradation.
When should I choose bifacial panels?
Bifacial panels are ideal when mounted on elevated structures (carports, pergolas) or ground mounts where light can reflect off the surface below. They generate 5-15% extra energy from the rear side. For standard flush rooftop installations, they offer little advantage.
