The use of **HPBC** technology allows for efficient operation even under less-than-ideal conditions on the roof, such as partial shading or complex roof geometries. The refined aesthetics - **black design** and low profile - ensure that the panels blend seamlessly with modern homes, without appearing like a "technical afterthought." The WR5-54HTH also emphasizes safety and durability: a robust construction with an **IP68 enclosure** and certifications (including **TUV and CE**) make it easy to select modules for projects requiring documented quality. It is a good choice for homeowners, twin houses, and small service buildings who want to combine high efficiency with aesthetics and long-term predictability, thanks to **long warranty** and reliable after-sales support. ## Notable figures - At 21.8% efficiency, this panel is on par with typical \*\*database\*\* modules - At 217.6 W/m² power density, roof space requirements are typical for \*\*database\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*database\*\* panels - At 20.8 kg, this panel is 5.7 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - #7022 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What is HPBC technology in the Weran Solar WR5-54HTH panels and is it worth choosing? HPBC (Hybrid Passivated Back Contact) is a back-contact cell technology where all electrical contacts are moved to the rear side of the module. As a result, the front surface of the WR5-54HTH panel has no visible busbars or grid lines, improving aesthetics and allowing more effective use of the cell surface. In practice this means higher conversion efficiency and better performance under partial shading compared to conventional PERC panels. ### Are WR5-54HTH panels suitable for roofs with complex geometry or partial shading? Yes, this is one of the main use cases for this series. The compact module dimensions (1722x1134 mm) make it easier to fit on irregular roof planes, and HPBC technology handles partial shading from chimneys, dormers, or antennas better than older cell technologies. The manufacturer highlights that the WR5-54HTH series is designed for roofs where occasional shading on part of the array is unavoidable. ### What warranty comes with the Weran Solar WR5-54HTH panels? The panels come with a 15-year product warranty covering material and workmanship defects, plus a 25-year power output warranty guaranteeing a minimum generation level over that period (typically around 88-89% of initial power after 25 years). This is a standard, predictable coverage period that helps with planning the return on investment for a solar installation. ### Do WR5-54HTH modules perform well in cold winter temperatures? Yes. The panels have a favorable power temperature coefficient of around -0.29%/°C, meaning a relatively small power drop at high temperatures and good efficiency in cooler conditions, typical of Polish winters. It's worth noting that lower temperatures combined with strong sunlight, such as in early spring, can even momentarily boost output compared to hot summer days. ### Do WR5-54HTH panels look good on a modern single-family house? Yes, the series was designed with aesthetics in mind - a black frame, black backsheet, and no visible metallic grid lines on the front (a result of HPBC technology) allow the panels to blend seamlessly with dark roofs and facades without a bulky, technical appearance. This makes it a popular choice for owners who want a uniform, consistent look across the roof surface. ### Is the junction box on the WR5-54HTH panels resistant to moisture and rain? Yes, the modules feature an IP68-rated junction box, the highest protection class commonly used in photovoltaics. This means full protection against dust and resistance to prolonged submersion in water, which matters for installations exposed to heavy rainfall, snow, or moisture. The panels also carry TUV and CE certifications, confirming compliance with safety standards applicable in Europe. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/english-product-brochures-7-split-3a65fbdcf02b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +50 W, +2.2 pp, +15 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +40 W, +2.0 pp, +5 yr warranty | | [JA Solar JAT54S40-475/LR](https://comparepv.com/panel/ja-solar-jat54s40-475-lr) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [Tongwei TWMNH-48HW475](https://comparepv.com/panel/tongwei-solar-twmnh-48hw475) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [Astronergy CHSM48RN(DG)/F-BH-475](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-475) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A475-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a475-mce54mw) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A475-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a475-mah54mw) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [Weran Solar WR5-54HTH-420M](https://comparepv.com/panel/weran-solar-wr5-54hth-420m) | 420 W | -0.3 pp | | [Weran Solar WR5-54HTH-430M](https://comparepv.com/panel/weran-solar-wr5-54hth-430m) | 430 W | Very close match | | [Weran Solar WR5-54HTH-435M](https://comparepv.com/panel/weran-solar-wr5-54hth-435m) | 435 W | +10 W, +0.5 pp | | [Weran Solar WR5-54HTH-440M](https://comparepv.com/panel/weran-solar-wr5-54hth-440m) | 440 W | +15 W, +0.7 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +85 W, +3.2 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +70 W, +3.0 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +80 W, +2.9 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +65 W, +2.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +75 W, +2.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/weran-solar-wr5-54hth-425m Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
