- At 23.7% efficiency, this panel is 1.9pp above typical database modules (median: 21.8%)
- 236.9 W/m² power density - 19.2 W/m² more than database median (217.7 W/m²), more power per roof area
- At -0.26%/°C (vs median -0.30%/°C), loses ~2% less power in hot conditions
- At 33.5 kg (7.0 kg above database median of 26.5 kg), requires checking roof load capacity
- Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof

Series HPBC 2.0 WR7-72HVD 640~665M 6 variants
The Weran Solar HPBC 2.0 WR7-72HVD series are modules designed for large-scale installations where high energy yield per square meter and real cost savings in construction and cabling are crucial. The use of back contact (BC) technology means that connections are moved to the back of the module – this allows the panel to better utilize sunlight and reduces losses due to shading from mounting structures. In practice, this translates to more stable energy production in Polish conditions, even in poor weather and with lower solar irradiance.
These are bifacial modules, meaning they can also utilize reflected light from the ground – this is particularly beneficial on PV farms, roofs with light-colored membranes, and ground-mounted installations in industrial areas. The series also features high durability and reliability in demanding scenarios, such as on heated roof surfaces of warehouses.
The WR7-72HVD would be a good choice for investors, EPC companies, and businesses that want to maximize yield and reduce LCOE without compromising on durability.
