A key advantage is the "**shingled” technology (module layout), which minimizes unused space on the module and reduces losses associated with traditional connections. This allows the panels to offer \high power density**, which is particularly beneficial when every square meter counts - in residential homes, multi-family buildings, and small commercial installations. PowerXT also features **improved performance in partially shaded conditions** - parallel connections between the strings minimize power loss when a shadow from a chimney, tree, or skylight covers part of the module. In addition, **connections without tape and soldering** are used, which reduces the number of potential failure points over the long term. The overall design features a **uniform, “pure black” appearance**, ideal for investors who prioritize a consistent architectural style. ## Notable figures - Efficiency of 19.9% is 1.9pp below the \*\*database\*\* median (21.8%) - Power density of 199.0 W/m² is 19.1 W/m² below \*\*database\*\* median (218.1 W/m²) - needs more roof space - Temperature coefficient of -0.39%/°C is 0.09pp worse than \*\*database\*\* median (-0.30%/°C) - higher losses in summer heat - At 21.0 kg, this panel is 5.5 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - Ranked #12331 out of 14005 panels for efficiency in the database ## Questions ### Is the Solaria PowerXT series still available for purchase? The Solaria PowerXT series has been discontinued and is no longer offered as a new product. A limited number of modules may still be available from distributors' existing stock, but full product range availability and continuous supply should not be expected. If you are planning an installation, check with your supplier for current inventory levels or consider comparable alternatives with similar shingled-cell technology. ### How does the shingled cell technology in Solaria PowerXT panels work and does it actually deliver more energy? Shingled technology cuts cells into narrow strips that are layered and bonded without busbars or soldering ribbons. This eliminates inactive gaps on the module surface and reduces resistive losses. In practice, Solaria PowerXT achieves higher power density per square meter than conventional PERC modules, translating into more energy harvested from the same roof area — a meaningful advantage when roof space is limited. ### What warranty does the Solaria PowerXT panel carry and what does it cover? Solaria PowerXT comes with a 30-year product warranty and a 30-year power output warranty — notably longer than the 25-year standard offered by most manufacturers. The product warranty covers manufacturing defects, while the power warranty guarantees the module will still produce a specified percentage of its rated output after 30 years. Since the series is discontinued, verifying warranty enforcement terms with your supplier before purchasing remaining stock is advisable. ### How does the Solaria PowerXT handle partial shading from a chimney or trees? The shingled architecture connects cell sub-strings in parallel, so shading from a chimney, tree, or dormer window causes a significantly smaller drop in energy yield compared to standard modules. The absence of solder joints and busbars also reduces hot-spot formation. Solaria PowerXT is a strong choice for rooftops with shading obstacles, though maximum performance is always achieved on a fully unobstructed surface. ### Is the Solaria PowerXT panel bifacial — does it generate power from both sides? No, the Solaria PowerXT series up to 430 Wp is a monofacial module — power is generated from the front side only. The rear surface features a uniform pure black finish that enhances the aesthetic appearance of the installation but does not capture additional reflected irradiance from the ground or rooftop surface. ### What is the maximum power output of the Solaria PowerXT and what type of installations is it best suited for? The top variant in the Solaria PowerXT lineup reaches 430 Wp. Its high power density makes it well suited for residential prosumer installations on single-family and multi-family homes where roof area is at a premium. It also fits small commercial rooftop systems. The pure black aesthetics appeal to homeowners who prioritize a clean, architecturally consistent look for their building. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5e746afc8eefb-2f4a75c094c2.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, +3.2 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.2 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +3.1 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.1 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.1 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, +3.1 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 | +40 W, +3.1 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 | +40 W, +3.1 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, +3.1 pp, +5 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +2.7 pp, +15 yr warranty | | [Solaria PowerXT-355R-AC](https://comparepv.com/panel/solaria-powerxt-355r-ac) | 355 W | Heavier, -0.3 pp | | [Solaria Solaria PowerXT-365R-PD](https://comparepv.com/panel/solaria-solaria-powerxt-365r-pd) | 365 W | +0.3 pp | | [Solaria Solaria PowerXT-370R-PD](https://comparepv.com/panel/solaria-solaria-powerxt-370r-pd) | 370 W | +10 W, +0.6 pp | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +80 W, cooler, +3.2 pp | | [SpolarPV SPV445-TM10-108](https://comparepv.com/panel/spolarpv-spv445-tm10-108) | 445 W | +85 W, cooler, +2.9 pp | | [Luxor Solar LX-435M/182-108+ GG](https://comparepv.com/panel/luxor-solar-lx-435m-182-108-gg-1) | 435 W | +75 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/solaria-solaria-powerxt-360r-pd-1 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
