The SunEvo Solar SE5-78HBD series are modules based on N-type cells using TOPCon technology, designed for high energy production even in challenging operating conditions. They stand out due to their bifacial design, which can utilize light reflected from the ground - effectively increasing energy yield in flat roofs, transparent membranes, or ground-mounted structures. The use of half-cut cells and multi-busbar connections improves performance under partial shading and reduces losses, which will be appreciated by investors in dense urban areas or with complex roof geometries. Thanks to its lower temperature coefficient, the module maintains better performance in summer, when standard panels lose power more quickly. Another strong argument is the long product warranty, which is essential for projects focused on stable returns on investment. The SE5-78HBD is a good choice for PV farms, large industrial rooftops, and installations where maximizing energy yield from available space is crucial.

About the SE5-78HBD series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the maximum power output of the SunEvo Solar SE5-78HBD and what does it mean for my system?
The SE5-78HBD reaches a maximum power of 635 Wp with a module efficiency of approximately 22%. This means more energy is generated per square meter than with a typical PERC panel. For a utility-scale PV farm or large commercial roof, fewer modules are needed to reach the target system capacity, which directly reduces racking and installation costs.
Are the bifacial SE5-78HBD panels suitable for a flat roof with a bright membrane?
Yes, this is one of the ideal use cases for this series. Bifacial technology allows the rear side of the module to harvest light reflected from the surface below - a white or light gray EPDM membrane can increase energy yield by 5-15% compared to a monofacial equivalent. Proper tilt angle is important to allow the rear cell surface to effectively capture diffuse and reflected irradiance.
How does TOPCon cell technology in the SE5-78HBD series affect performance during summer heat?
N-type TOPCon cells feature a lower temperature coefficient of Pmax at approximately -0.30%/°C. This means that when the panel heats up to 70°C on a hot sunny day, power losses are noticeably lower than with older PERC modules (approx. -0.35%/°C). In practice, this translates to several additional kWh produced annually, especially in regions with warm summers.
What warranty coverage does the SunEvo Solar SE5-78HBD come with?
The SE5-78HBD series includes a 25-year product warranty covering material defects and workmanship. The manufacturer also provides a 30-year power output warranty, guaranteeing a specified performance level throughout the module's operational life. Extended warranty terms are especially critical for projects targeting stable ROI, such as PV farms financed through project loans or leasing.
Are the SE5-78HBD modules compatible with standard inverters and typical racking systems?
The SE5-78HBD is compatible with string and central inverters operating within the wide MPPT voltage range typical of modules above 600 Wp. At 2465×1134 mm, the panel fits standard aluminum racking with mid-clamp hardware. Before purchasing, it is advisable to review the electrical design with a certified installer to select the correct number of modules per string and match the right inverter.
Is SunEvo Solar a Tier 1 manufacturer and does that matter when choosing SE5-78HBD panels?
SunEvo Solar is not currently listed as a Tier 1 manufacturer by major rating agencies such as Bloomberg NEF or PV InfoLink. For projects requiring project financing or bankability assessments, this may complicate loan approval. However, it does not directly affect module quality - the SE5-78HBD uses N-type TOPCon cells and carries a 25-year product warranty along with a 30-year power output guarantee.
