Unlike traditional modules, this series completely eliminates visible busbars and soldered connections, which drastically minimizes the risk of micro-cracks and increases the overall mechanical reliability of the entire system. A key technological advantage is the unique way of connecting cells, which makes these panels exhibit **exceptional shade resistance**. Specific, parallel sub-string connections allow for efficient energy production even in situations where part of the module is in transient shade, effectively solving common problems for owners of buildings with chimneys or dormers. This series was designed with the most demanding private investors in mind, for whom the **elegant Pure Black design** is key while maintaining the highest electrical parameters. Thanks to the maximum packing of the active surface, Solaria PowerXT-PD offers **higher power density** than competing products, allowing for optimal use of limited roof space. What distinguishes it from other solutions on the market is the almost complete **elimination of dead zones** on the module surface, which translates into a perfectly uniform appearance and maximization of photovoltaic yields over decades of operation. This is a premium-class solution, combining durability with uncompromising performance in difficult installation conditions. ## Notable figures - Module efficiency of 20.2% is 1.6pp below average for \*\*database\*\* panels (median: 21.8%) - At 201.8 W/m², this panel generates 16.3 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - 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 - In the top 85% for efficiency among all N-type panels ## Questions ### Are Solaria PowerXT-PD panels still available for purchase? The Solaria PowerXT-PD series has been discontinued and is no longer offered as a new product through official distribution channels. It may still be found in clearance stock at select distributors or on the secondary market. For new installations, we recommend checking Solaria's current PowerXT lineup or consulting an authorized installer to find a comparable available alternative. ### How does the shingled cell technology in Solaria PowerXT-PD differ from conventional solar panels? In the PowerXT-PD, cells are laser-cut and overlapped like roof shingles, with no busbars and no soldered interconnects. This eliminates mechanical stress that causes microcracks in standard modules. The result is higher mechanical reliability, virtually no inactive area on the module surface, a Pure Black aesthetic, and improved shade tolerance through parallel sub-string interconnection. ### Is the Solaria PowerXT-PD a good choice for a roof with a chimney or dormers? Yes, this is one of the series' key advantages. The parallel sub-string interconnection means that a shaded portion of the module does not shut down the remaining cells. In practice, the panel continues producing power even when a chimney or dormer casts a shadow across part of the module – a common challenge for residential rooftop installations. ### What warranty does the Solaria PowerXT-PD carry and what does it cover? Solaria provided a 25-year product warranty covering material defects and workmanship, along with a 25-year linear power output warranty guaranteeing the module retains a defined minimum percentage of its rated wattage throughout that period. For discontinued modules, warranty terms remain contractually binding, but we recommend confirming service procedures with your distributor or directly with Solaria. ### What is the peak power of the Solaria PowerXT-PD and how does it affect roof space utilization? The top variant in the PowerXT-PD series is rated at 370 Wp. Thanks to the shingled cell design and near-zero inactive surface area, the module delivers higher power density than conventional panels of similar dimensions. This translates to greater total system capacity from the same roof footprint, which is especially valuable when available installation space is limited. ### Is the Solaria PowerXT-PD a bifacial panel, and does it benefit from light-colored roofing surfaces? No, the PowerXT-PD is a monofacial module – it does not use bifacial technology. Energy is generated exclusively by the front surface, and the panel does not harvest albedo light reflected from the roof substrate. Roofing material color therefore has no effect on its output. If bifacial performance is a priority, a different series should be considered. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datasheet-PowerXT-Resi-370PD-Rev-04-138ce927d2b3.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, +2.9 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +2.9 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.8 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, +2.8 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 | +35 W, +2.8 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 | +35 W, +2.8 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, +2.8 pp, +5 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +2.4 pp, +15 yr warranty | | [Solaria PowerXT-355R-AC](https://comparepv.com/panel/solaria-powerxt-355r-ac) | 355 W | -10 W, heavier, -0.6 pp | | [Solaria Solaria PowerXT®-360R-PD](https://comparepv.com/panel/solaria-solaria-powerxt-360r-pd) | 360 W | -0.3 pp | | [Solaria Solaria PowerXT-370R-PD](https://comparepv.com/panel/solaria-solaria-powerxt-370r-pd) | 370 W | +0.3 pp | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +75 W, cooler, +2.9 pp | | [SpolarPV SPV445-TM10-108](https://comparepv.com/panel/spolarpv-spv445-tm10-108) | 445 W | +80 W, cooler, +2.6 pp | | [Luxor Solar LX-435M/182-108+ GG](https://comparepv.com/panel/luxor-solar-lx-435m-182-108-gg-1) | 435 W | +70 W, cooler, +2.6 pp | --- Source: https://comparepv.com/panel/solaria-solaria-powerxt-365r-pd Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
