These panels stand out for their **resistance to salt mist and ammonia**, making them well suited for agricultural rooftops as well as coastal locations, where aggressive atmospheric factors quickly degrade cheaper constructions. The module frame has been reinforced for **mechanical load resistance** - certified to withstand wind loads up to 2400 Pa and snow loads up to 5400 Pa, making it a solid choice for regions with harsh climates. Grade A PERC cells with anti-PID technology guarantee **resistance to potential-induced degradation**, translating into stable energy output throughout the module's service life. The manufacturer offers a **positive power tolerance of up to 3%**, eliminating the risk of underestimating actual system performance, and combined with a **25-year linear power warranty** and an annual degradation rate of just 0.65%, it gives investors a predictable return on investment. The PS-M72 series works well both in residential rooftop installations and in larger commercial projects and solar power plants, where long-term durability and a low levelized cost of energy (LCOE) matter most. ## Notable figures - Efficiency of 19.8% matches the \*\*PERC 0-400W\*\* median - 197.6 W/m² power density - 3.4 W/m² more than \*\*PERC 0-400W\*\* median (194.2 W/m²), more power per roof area - Temperature coefficient of -0.39%/°C is 0.03pp worse than \*\*PERC 0-400W\*\* median (-0.36%/°C) - higher losses in summer heat - Weight of 22.0 kg is 1.5 kg above \*\*PERC 0-400W\*\* median (20.5 kg) - verify structural support - #12501 for efficiency, #13659 for temperature performance out of 14129 panels ## Questions ### Is the Philadelphia Solar PS-M72 series still available for purchase? The PS-M72 series has been discontinued from current production by Philadelphia Solar and replaced by newer, higher-power models. Units may still be available through distributors as remaining stock, but buyers should confirm availability and production date with the seller, since the manufacturer no longer guarantees continuous supply or warranty service tied to this specific model. ### Are PS-M72 panels suitable for coastal or agricultural installations? Yes, this is one of the series' main strengths. PS-M72 modules are certified for resistance to salt mist and ammonia, making them well-suited both for installations near the coast, where salty humidity accelerates corrosion, and for roofs on livestock buildings, where ammonia fumes degrade cheaper module constructions. ### What warranty does Philadelphia Solar offer on the PS-M72 panels? The manufacturer provides a 12-year product warranty along with a 25-year linear power warranty. Annual power degradation is only 0.65 percent, meaning the panel should retain a high percentage of its initial power output after 25 years of operation. These are standard terms for a Tier 1 manufacturer like Philadelphia Solar. ### What is the maximum power output of the PS-M72 panel, and is it bifacial? PS-M72 series panels reach a maximum power of up to 385 Wp. These are monofacial modules, not bifacial, meaning they generate energy only from the front surface. For applications requiring extra energy yield from reflected light, other bifacial series from the manufacturer should be considered instead. ### How does the PERC technology in the PS-M72 differ from standard monocrystalline cells? PERC cells feature an additional rear passivation layer that reflects unused light back into the cell, increasing conversion efficiency compared to standard mono cells. The PS-M72 uses Grade A PERC cells with anti-PID technology, further protecting the panel against potential-induced degradation over long-term system operation. ### Can PS-M72 panels withstand heavy snow loads and strong wind? Yes, the module frame is reinforced for mechanical strength and certified to withstand wind loads up to 2400 Pa and snow loads up to 5400 Pa. This makes the PS-M72 series suitable for regions with harsh climates, including areas with heavy winter snowfall and strong summer winds. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/PS-M72-370-385W-5ed22ed76128.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.2 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.2 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, +3.2 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, +3.2 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, +3.2 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, +3.2 pp, +5 yr warranty | | [Luxor Solar LX-435M/182-108+ GG](https://comparepv.com/panel/luxor-solar-lx-435m-182-108-gg-1) | 435 W | +50 W, cooler, +3.0 pp | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +50 W, cooler, +2.9 pp | | [Maxeon SPR-MAX3-430-R](https://comparepv.com/panel/maxeon-spr-max3-430-r) | 430 W | Cooler, +2.9 pp, +15 yr warranty | | [Luxor Solar LX-435M/182-108+](https://comparepv.com/panel/luxor-solar-lx-435m-182-108) | 435 W | +50 W, cooler, +2.8 pp | | [Philadelphia Solar PS-P72-330W](https://comparepv.com/panel/philadelphia-solar-ps-p72-330w) | 330 W | -55 W, hotter, -2.9 pp | | [Philadelphia Solar PS-P72-335W](https://comparepv.com/panel/philadelphia-solar-ps-p72-335w) | 335 W | -50 W, hotter, -2.6 pp | | [Philadelphia Solar PS-P72-340W](https://comparepv.com/panel/philadelphia-solar-ps-p72-340w) | 340 W | -45 W, hotter, -2.3 pp | | [Philadelphia Solar PS-P72-345W](https://comparepv.com/panel/philadelphia-solar-ps-p72-345w) | 345 W | -40 W, hotter, -2.1 pp | | [Philadelphia Solar PS-M72-370W](https://comparepv.com/panel/philadelphia-solar-ps-m72-370w) | 370 W | -15 W, -0.8 pp | | [Philadelphia Solar PS-M72-375W](https://comparepv.com/panel/philadelphia-solar-ps-m72-375w) | 375 W | -10 W, -0.6 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | Cooler, +4.2 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m72-385w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
