This means limited availability of identical replacement modules in case of failure and potential difficulties with warranty servicing over the long term. - **Efficiency well below current market standards** - Efficiency of 16.9-17.7% is roughly 3 percentage points lower than comparable mono PERC/half-cut modules in this power segment, such as Canadian Solar HiDM (20.5%), Jinko Cheetah HC 60M-V (20.45%), or Solar N Plus AP1 (20.45%). For the same power output, the panel requires significantly more roof or ground area. ## About this series The PS-P72-(330-345W) series comprises polycrystalline photovoltaic modules engineered to endure demanding operating conditions over decades of service. The panels are built around 72 grade-A polycrystalline cells arranged in a 12x6 layout, manufactured on fully robotic production lines with electroluminescence quality control that ensures consistent parameters across every unit. The modules are **resistant to PID degradation** thanks to PID-free EVA encapsulant, while the sturdy anodized aluminum frame and anti-reflective coated tempered glass deliver **high resistance to mechanical loads, wind, and snow**. The manufacturer also highlights **resistance to salt mist and ammonia**, making this series a solid choice for coastal installations and agricultural sites, where aggressive environments quickly wear down cheaper panels. Another advantage is **excellent low-light performance**, useful in regions with variable cloud cover. The series is backed by a **25-year linear power warranty with annual degradation of just -0.7%**, giving investors a predictable return on their installation. It's a solution for installers seeking a proven, bankable product for residential, commercial, and industrial applications, including both on-grid and off-grid systems. ## Notable figures - At 17.7% efficiency, this panel is 4.1pp below the \*\*database\*\* median of 21.8% - At 177.1 W/m², this panel generates 41.0 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - -0.40%/°C temperature coefficient - 0.10pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - 21.0 kg weight - 5.5 kg lighter than \*\*database\*\* median (26.5 kg), reducing installation effort - Ranked #13404 out of 14129 panels for efficiency in the database ## Questions ### Is the PS-P72-(330-345W) series still available for purchase? No, the PS-P72-(330-345W) series has been discontinued from Philadelphia Solar's current production lineup. Remaining stock may still be available through distributors, so it's worth checking current availability, or consider the manufacturer's newer modules with higher unit power and comparable build quality. ### What warranty comes with the PS-P72-(330-345W) panels? The manufacturer offers a 12-year product warranty along with a 25-year linear power warranty featuring an annual degradation rate of just -0.7%. This means the panel should retain well over 80% of its initial output after 25 years, giving investors a predictable, long-term return on their installation. ### Are PS-P72-(330-345W) panels suitable for coastal installations? Yes, this series is tested for resistance to salt mist and ammonia, making it a solid choice for both coastal installations and agricultural sites with livestock, where aggressive fumes quickly degrade cheaper modules. The anodized aluminum frame provides additional corrosion protection in these conditions. ### How does the PS-P72-(330-345W) differ from monocrystalline modules? The PS-P72 series uses 72 Grade A polycrystalline cells in a 12x6 configuration, delivering slightly lower efficiency per square meter than monocrystalline modules, but offering more stable output and a competitive price point. The panel performs well under low irradiance, an advantage in regions with variable cloud cover. ### Are Philadelphia Solar PS-P72 panels resistant to PID degradation? Yes, the modules use PID-free EVA encapsulant, preventing potential-induced degradation. This keeps power output stable even under the high system voltages typical of large-scale solar farms and industrial installations. ### Who manufactures the PS-P72-(330-345W) panels, and are they Tier 1? The panels are manufactured by Philadelphia Solar, headquartered in Jordan and classified as a Tier 1 manufacturer, placing it among the most financially reliable module producers. Production runs on fully robotic lines with electroluminescence quality control applied to every unit. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/PS-P72-330-345W-5ce2fae9a9f4.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | Cooler, +2.4 pp | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | Cooler, lighter, +2.2 pp | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | Cooler, +2.2 pp, +5 yr warranty | | [Canadian Solar CS3U-395P](https://comparepv.com/panel/canadian-solar-cs3u-395p) | 395 W | +50 W, cooler, +2.2 pp | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | -10 W, cooler, +2.1 pp | | [Canadian Solar CS3L-365P](https://comparepv.com/panel/canadian-solar-cs3l-365p) | 365 W | +20 W, cooler, +2.0 pp | | [Canadian Solar CS3U-390P](https://comparepv.com/panel/canadian-solar-cs3u-390p) | 390 W | +45 W, cooler, +2.0 pp | | [Philadelphia Solar PS-P72-330W](https://comparepv.com/panel/philadelphia-solar-ps-p72-330w) | 330 W | -15 W, -0.8 pp | | [Philadelphia Solar PS-P72-335W](https://comparepv.com/panel/philadelphia-solar-ps-p72-335w) | 335 W | -10 W, -0.5 pp | | [Philadelphia Solar PS-P72-340W](https://comparepv.com/panel/philadelphia-solar-ps-p72-340w) | 340 W | Very close match | | [Philadelphia Solar PS-M72-370W](https://comparepv.com/panel/philadelphia-solar-ps-m72-370w) | 370 W | +25 W, cooler, +1.3 pp | | [Philadelphia Solar PS-M72-375W](https://comparepv.com/panel/philadelphia-solar-ps-m72-375w) | 375 W | +30 W, cooler, +1.5 pp | | [Philadelphia Solar PS-M72-380W](https://comparepv.com/panel/philadelphia-solar-ps-m72-380w) | 380 W | +35 W, cooler, +1.8 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +130 W, +6.3 pp, +15 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | Cooler, +6.0 pp, +15 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | Cooler, +5.8 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-p72-345w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
