TopCon N-type and PERC are the two dominant module technologies in the current PV market. Which one fits your project depends on budget, available roof or land area, and lifetime cost targets.

TopCon modules offer 1.5-2% higher efficiency, lower degradation and a better temperature coefficient, making them ideal for high-temperature regions and area-limited installations. PERC modules remain the most cost-effective choice for projects with abundant land.

As TopCon production capacity expands in 2026, the price gap between the two technologies keeps narrowing. For most new projects we recommend TopCon for rooftops and PERC for ground-mounted utility farms. Contact LACO NEW ENERGY for a detailed module selection report.
