TopCon vs Mono PERC: Summer Yield Delta

A data-driven analysis of why N-Type modules deliver 18% higher yield in heat.

Published: 06 Aug 2026

In Delhi summer temperatures, module temperature coefficients decide your actual yield. N-Type TOPCon cells run cooler and degrade slower than P-Type PERC.

Why N-Type Wins in Heat

Lower temperature coefficient (-0.29%/°C vs -0.35%/°C) and bifacial gain keep N-Type arrays ahead through June peak months.
