Series Runergy HY-DH108N8B 425-445W are modules designed for maximum energy yield on limited roof surfaces. The application of N-type cells and refined connection architecture enables stable operation even under less-than-ideal conditions - such as light cloud cover, cooler mornings, or less favorable exposure. This is a real advantage in Polish installations, where year-round production matters, not just under full sun.

A key feature of this series is double glass, which increases resistance to environmental factors and limits the risk of micro-cracks, contributing to the installation's longevity. The modules also offer high resistance to LID and LeTID degradation, ensuring predictable parameters for years to come. An additional benefit is beneficial performance at higher temperatures, helping to mitigate power losses during summer.

This is a good choice for single-family homes, commercial buildings, and rooftop installations, where reliability, aesthetics, and long-term energy yield are important.

About the HY-DH108N8B 425-445W series

6 answered

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

What warranty comes with the Runergy HY-DH108N8B 425-445W solar panels?
The HY-DH108N8B series comes with a 25-year product warranty covering materials and workmanship, plus a 30-year linear power warranty. Annual degradation after the first year is below 0.4%, meaning the module retains at least 87.4% of its rated output after 30 years. This is one of the longer power warranty standards currently available on the market.
Is the Runergy HY-DH108N8B a bifacial panel, and what does that mean in practice?
Yes, the HY-DH108N8B is a bifacial module, meaning both sides generate electricity. Bifaciality is rated at 80% ±5%, so the rear side can produce up to 80% of the front-side output under suitable conditions. On reflective surfaces - white gravel, concrete, or snow - or in tilted ground-mount systems, annual energy yield can increase by several to over ten percent compared to a monofacial module.
Are the Runergy HY-DH108N8B panels suitable for a standard pitched residential rooftop?
Yes. The modules measure 1722 × 1134 × 30 mm and weigh approximately 24.2 kg, which fits standard rooftop installation parameters. The dual-glass construction improves resistance to mechanical loads, while the low temperature coefficient helps maintain output during summer. The series performs well on south, south-east, or south-west facing rooftops.
How does N-type cell technology in the HY-DH108N8B differ from standard PERC panels?
N-type cells used in the HY-DH108N8B are significantly less susceptible to LID and LeTID degradation compared to p-type PERC cells. This results in smaller power losses in the first years of operation and a more predictable long-term yield. N-type cells also perform better in low-irradiance conditions and at lower temperatures, which provides a real advantage in climates with variable weather.
How does the HY-DH108N8B perform during hot summer days?
N-type modules, including the HY-DH108N8B, have a more favorable temperature coefficient than PERC, which means less power loss on hot days. The dual-glass construction also helps reduce heat buildup. In practice, these panels lose less output during summer heat waves, resulting in higher annual energy yield compared to older-generation modules.
Is Runergy a reliable manufacturer, and can I trust the HY-DH108N8B for a long-term installation?
Runergy holds Bloomberg NEF Tier 1 status, meeting rigorous financial and manufacturing criteria assessed by independent analysts. The company operates its own ingot, wafer, and cell production lines. The HY-DH108N8B carries the certifications required for the European market. For installers and investors, Tier 1 status also simplifies access to financing and insurance for the system.
