This solution completely eliminates traditional busbars and unused gaps between cells, which not only translates into an elegant, uniform appearance but, above all, maximizes the active area of the module. Thanks to the unique parallel connection architecture, this series perfectly handles challenges such as **shade resistance**, significantly minimizing energy losses in difficult installation conditions. It is an ideal choice for demanding investors with limited roof space who do not want to compromise on maximum energy yields. The absence of visible soldered connections drastically increases the **mechanical reliability** of the entire structure, effectively protecting it against the formation of dangerous micro-cracks during long-term operation. Solaria PowerXT 54L stands out from the competition with an **uncompromising all-black design** that harmoniously blends with the modern architecture of residential buildings. By choosing these modules, you gain the assurance of longevity and the **highest power density** from every square meter of roofing, making them one of the most prestigious and cost-effective investments in the premium segment for home photovoltaic systems. The innovative design also ensures better thermal stability, which is crucial during hot days. ## Notable figures - At 19.4% efficiency, this panel is on par with typical \*\*PERC 0-400W\*\* modules - Power density of 194.9 W/m² matches the \*\*PERC 0-400W\*\* median - Temperature coefficient of -0.35%/°C matches the \*\*PERC 0-400W\*\* median - #12717 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### What warranty does the Solaria PowerXT 54L come with? The Solaria PowerXT 54L carries a 12-year product warranty covering material and workmanship defects. In addition, Solaria provides a 25-year linear power output warranty, guaranteeing the module will produce a defined minimum percentage of its rated 380 Wp throughout that period. Both coverages are consistent with premium-tier residential solar standards and reflect the long-term reliability of the shingled cell design. ### How does the Solaria PowerXT 54L handle partial shading from a chimney or antenna? The shingled cell architecture in the Solaria PowerXT 54L connects cells in parallel strings, so shading one section of the module does not dramatically cut the output of the entire panel. According to manufacturer data, this design delivers up to 40% better performance under partial shading compared to conventional busbar-based panels, making it well-suited for residential rooftops with chimneys, dormers, or antennas. ### What are PERC shingled cells and why does Solaria use them in the PowerXT 54L? Shingled cells are PERC solar cells sliced into thin strips and overlapped like roof shingles, bonded with conductive adhesive instead of soldered busbars. In the Solaria PowerXT 54L, this eliminates inter-cell gaps, maximizes the active front-side area of the module, and significantly reduces the risk of microcracks since no soldering is involved. The resulting assembly handles mechanical stress and thermal cycling much better over the full 25-year power warranty period. ### What is the peak power of the Solaria PowerXT 54L and is it a good fit for a small roof? The Solaria PowerXT 54L is rated at 380 Wp peak. By eliminating busbars and inter-cell gaps, the module achieves high power density, meaning more watts per square meter of roof area. This makes it an ideal choice for homeowners with limited roof space who want to maximize energy yield without expanding the number of modules in their system or rethinking the mounting structure. ### Does the all-black design of the Solaria PowerXT 54L affect operating temperature and efficiency? The all-black surface can slightly raise the module's operating temperature compared to standard panels, but the Solaria PowerXT 54L is engineered for thermal stability. The shingled cell construction improves heat management by removing soldered busbars, which reduces mechanical stress during thermal cycling. The aesthetic benefit of the all-black finish, which complements modern residential architecture, does not represent a meaningful efficiency trade-off in real-world conditions. ### Is the Solaria PowerXT 54L a bifacial panel — does it generate power from both sides? No, the Solaria PowerXT 54L is a monofacial module — electricity is generated only from the front side. The panel uses an opaque backsheet, so it does not collect reflected irradiance from the ground or rooftop surface. This is offset by the shingled cell layout, which maximizes the front-side active area to deliver 380 Wp from a compact, uniform all-black module footprint. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SPV-RYGB-088d0b83a608.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.7 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.7 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.6 pp, +5 yr warranty | | [Maxeon SPR-MAX3-430-R](https://comparepv.com/panel/maxeon-spr-max3-430-r) | 430 W | Cooler, +3.2 pp, +15 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +3.2 pp, +15 yr warranty | | [Solaria SP310RHM6-54L](https://comparepv.com/panel/solaria-sp310rhm6-54l) | 310 W | -70 W, -3.6 pp | | [Solaria SP350YHM6-54L](https://comparepv.com/panel/solaria-sp350yhm6-54l) | 350 W | -30 W, -1.5 pp | | [Solaria SP370GHM6-54L](https://comparepv.com/panel/solaria-sp370ghm6-54l) | 370 W | -10 W, -0.5 pp | | [Solaria Solaria PowerX-390R](https://comparepv.com/panel/solaria-solaria-powerx-390r) | 390 W | Hotter, heavier, +0.6 pp | | [Solaria Solaria PowerX-395R](https://comparepv.com/panel/solaria-solaria-powerx-395r) | 395 W | +15 W, heavier, +0.8 pp | | [Solaria Solaria PowerX-400R](https://comparepv.com/panel/solaria-solaria-powerx-400r) | 400 W | +20 W, heavier, +1.1 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +130 W, cooler, +5.6 pp | --- Source: https://comparepv.com/panel/solaria-sp380bhm6-54l Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
