Solar Panel Comparison

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.

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.

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.

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.
