PRODUCT HIGHLIGHTS
Why Rove N1.
N-Type TOPCon Bifacial · Dual Glass Solar Module. 620–640 W of front-side rated power, with the construction and operating characteristics detailed below.
Bifacial power generation
The module specifies 80 ±5% bifaciality. Rear-side gain scenarios are tabulated separately from the 620-640 W front-side STC ratings.
Heat-strengthened dual glass
2.0 mm AR-coated front glass and 2.0 mm rear glass use an anodized aluminum frame. Listed wind and snow loads are 2400 Pa and 5400 Pa.
IP68 junction box and low temperature coefficient
The IP68 junction box has three diodes. The module specifies a -0.28%/°C Pmax coefficient and an operating temperature range of -40°C to +85°C.
