In typical ground-mount installations this translates into an additional yield of several to low-teens percent versus comparable monofacial modules of similar power. - **Half-cut cells reduce resistive losses** - Half-cut cell design reduces resistive losses and improves the module's tolerance to partial shading, resulting in more stable output under uneven irradiance compared to full-cell modules. - **Glass-glass construction with low PID susceptibility** - A dual tempered glass build with an anti-reflective coating replaces the standard rear backsheet, improving mechanical rigidity and limiting power degradation from potential-induced degradation (PID) - relevant for utility-scale installations operating in high-humidity environments. - **Tier-1 bankable manufacturer, 19 years in operation** - Philadelphia Solar is a Tier-1 (bankable) manufacturer headquartered in Jordan, operating since 2007 with a 580 MW production facility, which supports project bankability and boosts investor confidence in the supplier. - **25-year power warranty and 12-year product warranty** - The manufacturer provides a standard full 25-year linear power warranty along with a 12-year product warranty, consistent with the industry benchmark for Tier-1 PERC modules from this production era. ## Cons - **Series discontinued** - The PS-M72(BF) series (launched in 2020) has been discontinued, limiting the availability of identical modules for extending an existing installation and potentially complicating warranty service and spare-part matching over the long term. - **Efficiency below current peer comparables** - Efficiency of 19-19.8% is notably lower than comparable 385 Wp modules: Solarwatt Panel vision GM 3.0 pure (20.7%), Suntech Ultra S mini (21.1%), and JA Solar JAM60D20 (20.6%). At the same peak power, the module has a larger footprint, increasing space requirements and mounting structure costs. ## About this series The PS-M72(BF) series comprises dual-sided monocrystalline PERC photovoltaic modules that, thanks to **bifacial technology**, recover additional energy reflected from the ground, roof, or surrounding surfaces of the installation. The use of **half-cut cells** reduces resistive losses and increases the panel's tolerance to partial shading, resulting in more stable performance under challenging irradiance conditions. A dual tempered glass construction with an anti-reflective coating replaces the traditional rear backsheet, improving mechanical rigidity and extending module lifespan while enabling power generation from both sides of the panel. The design's **low susceptibility to PID** protects against potential-induced degradation, a key consideration for ground-mounted installations and solar farms operating in higher-humidity environments. Panels in this series perform especially well on high-albedo surfaces such as light-colored roofs, gravel, or snow, where the bifacial effect delivers a measurable increase in energy yield without expanding the installation footprint. It's a solid choice for investors and installers seeking lower LCOE and better weather resilience compared to conventional monofacial modules, while remaining fully compatible with standard mounting systems and inverters used in commercial and industrial installations. ## Notable figures - Efficiency of 19.0% matches the \*\*PERC 0-400W\*\* median - At 189.9 W/m², this panel generates 4.3 W/m² less per unit area than \*\*PERC 0-400W\*\* median (194.2 W/m²) - At -0.37%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - At 22.0 kg, this panel is 1.5 kg heavier than the \*\*PERC 0-400W\*\* median (20.5 kg) - more demanding for installation crews - 75% bifaciality enables rear-side power generation, boosting yield by 4-11% on reflective surfaces ## Questions ### Is the Philadelphia Solar PS-M72(BF) series still available for purchase? The PS-M72(BF) series has been discontinued and replaced by newer models from the manufacturer. Panels may still be available from distributor stock as remaining inventory, but buyers should confirm availability and production date, since once existing stock is depleted the modules can no longer be ordered directly from Philadelphia Solar. ### What does bifacial technology offer in PS-M72(BF) panels, and is it worth the extra cost? Thanks to the dual tempered glass, the module also generates power from its rear side by capturing light reflected off the ground. On light-colored roofs, gravel, or snow, this can add several to double-digit percentage points of extra energy yield without increasing the installation footprint, lowering LCOE. On dark roofs or with low mounting clearance, the gain can be marginal, so payoff depends on the specific site. ### What warranty applies to PS-M72(BF) panels and their power output? Philadelphia Solar provides a 12-year product warranty along with a 25-year power performance warranty. This means protection against manufacturing defects for 12 years, while the manufacturer guarantees a specified minimum power output level over a quarter century of operation, which is standard for Tier 1 panels. ### How do the half-cut cells in PS-M72(BF) differ from standard full-size cells? Half-cut cells are cut in half, reducing resistive losses and the current flowing through each cell path. This results in higher panel efficiency and better resilience to partial shading, such as from a chimney or leaves, since shading one half of a cell has less impact on the entire module's output compared to conventional full-size cells. ### Are PS-M72(BF) modules suitable for solar farms and ground-mounted installations? Yes, the low PID susceptibility design combined with bifacial technology make this series a good fit for ground-mounted installations and solar farms with elevated humidity and large high-albedo surfaces. Panels rated up to 385 Wp help reduce the number of modules needed to reach a target installation power. ### Does Philadelphia Solar as a manufacturer offer quality assurance for the PS-M72(BF) modules? Philadelphia Solar is a Tier 1 manufacturer headquartered in Jordan, established in the market for years and regularly audited for financial stability and production quality. Tier 1 status means the company self-finances its own production lines and supplies panels to large commercial projects, adding credibility to the long-term warranty despite this particular series being discontinued. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/PS-M72BF-370-385W-470e91756081.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, +4.1 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +4.1 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -50 W, lighter, +4.0 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +4.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +4.0 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, +4.0 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, +4.0 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, +4.0 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, +4.0 pp, +5 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +3.6 pp, +15 yr warranty | | [Philadelphia Solar PS-P72-330W](https://comparepv.com/panel/philadelphia-solar-ps-p72-330w) | 330 W | -40 W, hotter, -2.1 pp | | [Philadelphia Solar PS-P72-335W](https://comparepv.com/panel/philadelphia-solar-ps-p72-335w) | 335 W | -35 W, hotter, -1.8 pp | | [Philadelphia Solar PS-P72-340W](https://comparepv.com/panel/philadelphia-solar-ps-p72-340w) | 340 W | -30 W, hotter, -1.5 pp | | [Philadelphia Solar PS-P72-345W](https://comparepv.com/panel/philadelphia-solar-ps-p72-345w) | 345 W | -25 W, hotter, -1.3 pp | | [Philadelphia Solar PS-M72-375W](https://comparepv.com/panel/philadelphia-solar-ps-m72-375w) | 375 W | Hotter | | [Philadelphia Solar PS-M72-380W](https://comparepv.com/panel/philadelphia-solar-ps-m72-380w) | 380 W | +10 W, hotter, +0.5 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +105 W, +5.0 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m72-bf-370w Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
