Smart Insights (data-driven)
  • 24.4% module efficiency - 2.6pp better than the database median of 21.8%
  • Power density of 244.3 W/m² packs 26.6 W/m² more into the same footprint vs database median (217.7 W/m²)
  • Temperature coefficient of -0.26%/°C vs median -0.30%/°C means ~2% less power loss at 65°C
  • 33.5 kg weight exceeds %!s(float64=7) median by %!f(string=d) kg (26.5 kg) - heavier for installation crews
  • Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof

Show series description

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.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
