The Weran Solar LR7-72HTH 595~620M series is designed for installations where maximizing energy yield per square meter and predictable performance over many years are crucial. Its foundation is the HPBC (back contact) cell technology, which means the front side of the module does not have traditional busbars - this allows for better light utilization and aesthetics, which are highly valued in premium projects. In practice, this translates to stable energy production even in less sunny conditions and under variable weather conditions typical of Poland. The fully sealed rear construction improves resistance to microcracks, which makes logistics and installation easier, especially for large modules. An additional advantage is the positive power tolerance, which reduces the risk of underestimating energy yields in a project. This makes it a good choice for installers and investors building solar farms and commercial installations who are looking for lower BOS (balance of system) and transportation costs without compromising on quality.

Common questions

6 answered
What is HPBC technology in the Weran Solar LR7-72HTH 595~620M panels and how does it differ from conventional busbar cells?
HPBC (Heterojunction Passivated Back Contact) places all cell electrodes on the rear side of the cell. The front surface of the module has no visible busbars, so more sunlight reaches the silicon directly. This results in higher efficiency (up to 23.0%) and a uniform, aesthetic appearance valued in premium installations and street-facing projects.
What warranty comes with the Weran Solar LR7-72HTH 595~620M panels?
The manufacturer provides a 12-year product warranty and a 25-year linear power warranty. First-year degradation is under 1%, and annual degradation afterward does not exceed 0.40%, meaning the panel should retain over 87% of its initial power output after 25 years of operation.
Are the Weran Solar LR7-72HTH 595~620M panels still available for purchase?
No, this series has been discontinued and is no longer in active production, so it is not available as a new order from the manufacturer. Units may still be found in distributor stock. Buyers planning new installations should ask about current equivalent models from Weran Solar or LONGi, the manufacturer this series was distributed from.
Do the LR7-72HTH 595~620M panels perform well in low temperatures and variable sunlight?
Yes. The power temperature coefficient is -0.28%/°C, meaning the output drop at higher temperatures is smaller than in typical busbar-cell panels. The absence of front-side busbars also improves capture of diffuse light, allowing the panels to perform more consistently under overcast skies and low sun angles, both common in Polish winters.
What type of installation is the Weran Solar LR7-72HTH 595~620M panel best suited for - rooftop or utility-scale farms?
Given its large size (2382x1134x30 mm) and weight of 28.5 kg, this panel is primarily aimed at commercial installations and utility-scale solar farms, where maximizing yield per unit of roof or ground area matters most. The high per-module power output (up to 620 Wp) reduces the number of panels, mounting structures, and cabling needed, lowering BoS and transport costs in large projects.
How does the LR7-72HTH 595~620M differ from the bifacial version in the Weran Solar lineup?
This series is monofacial, generating power only from the front side of the module. Bifacial variants in the HPBC/HJD family also capture light reflected off the ground, potentially boosting energy yield by several percent, but they require suitable mounting conditions (e.g., a reflective surface or ground-mounted racking) and typically cost more. A monofacial module is the right choice where site conditions can't take advantage of the albedo effect.
