Why this unit
Three points that matter at specification stage.
A transparent rear glass and 80 ± 5% bifaciality let the module harvest reflected light from roofs and ground surfaces.
1% first-year degradation and 0.4% per year thereafter, with 87.4% output at year 30 under the manufacturer's linear warranty.
1500 V DC system voltage and a 132 half-cell layout keep string counts and balance-of-system costs down.
