For the same output, the PS-P60 requires more roof or ground area. - **Warranty below current market standards** - A 12-year product warranty and 25-year linear power warranty (degrading to roughly 80.7%) lag behind today's tier-1 offerings, where 25-30 year product warranties and 87-88% power retention at 30 years are becoming the norm. ## About this series The PS-P60 (275-290 W) series comprises poly-crystalline photovoltaic modules manufactured by Philadelphia Solar on fully automated, robotic production lines, delivering consistent grade-A cell quality and minimal parameter mismatch between units. The series stands out with its **positive power tolerance up to 3%**, meaning installers always receive a panel that meets or exceeds its rated output, removing the risk of underestimating energy yield. Tempered anti-reflective glass paired with PID-free EVA encapsulant provides **resistance to potential-induced degradation (PID)** and stable performance over the entire operational lifetime. The modules are also **resistant to salt mist and ammonia**, making them a sound choice for coastal installations and agricultural sites where aggressive environments quickly degrade cheaper panels. The anodized aluminum frame confirms **high mechanical strength against snow and wind loads**, an important factor for large rooftop arrays and ground-mounted solar power plants. The PS-P60 series performs well in on-grid residential systems as well as commercial and industrial projects, offering investors predictable linear power degradation and a long-term product warranty backed by a DNV GL bankability report. ## Notable figures - At 17.8% efficiency, this panel is 4.0pp below the \*\*database\*\* median of 21.8% - Power density of 177.8 W/m² is 40.3 W/m² below \*\*database\*\* median (218.1 W/m²) - needs more roof space - At -0.40%/°C, loses 0.10pp more power per degree than \*\*database\*\* median (-0.30%/°C) - 18.0 kg weight - 8.5 kg lighter than \*\*database\*\* median (26.5 kg), reducing installation effort - #13377 for efficiency, #13798 for temperature performance out of 14129 panels ## Questions ### Is the Philadelphia Solar PS-P60 (275-290 W) series still available for purchase? The PS-P60 (275-290 W) series has been discontinued from current production by Philadelphia Solar. These panels may still be found in distributor warehouses or as limited stock, but the manufacturer has shifted focus to newer, higher-power modules. Buyers should confirm current stock availability and warranty validity with their supplier, as remaining inventory will not be replenished. ### What warranty comes with the PS-P60 275-290 W panels? Philadelphia Solar provides a 12-year product warranty and a 25-year linear power output warranty on the PS-P60 series. This means that after a quarter century of operation, the panel should still deliver a significant share of its rated initial power. The modules also feature a positive power tolerance of up to 3%, so actual output often exceeds the nameplate value. ### Are PS-P60 panels suitable for coastal or agricultural installations? Yes, this series is certified for resistance to salt mist and ammonia, making it a suitable choice for both coastal installations and agricultural buildings such as poultry houses or barns. In these environments, panels without such certification suffer much faster frame corrosion and cell degradation. ### Can PS-P60 panels withstand heavy snow loads and strong winds? Yes, the panels feature a reinforced anodized aluminum frame that provides high mechanical strength against snow load and wind pressure. This makes them well suited both for rooftops in heavy-snowfall regions and for large ground-mounted solar farms exposed to strong gusts, without risk of frame deformation or glass cracking. ### What is PID resistance in the PS-P60 panels and why does it matter? PID (potential-induced degradation) is a phenomenon that gradually reduces panel output due to high voltage stress within a string of modules. PS-P60 panels use PID-free EVA encapsulant and tempered anti-reflective glass to protect the cells from this effect. This ensures stable performance throughout the system's lifetime, especially in large arrays with many series-connected panels. ### Is Philadelphia Solar a tier 1 manufacturer, and what does that mean for buyers? Yes, Philadelphia Solar, headquartered in Jordan, holds tier 1 status, confirming the company's financial stability and product bankability. The PS-P60 series is backed by a DNV GL bankability report, which makes it easier to secure bank or leasing financing for a project and gives investors confidence in product quality and the long-term warranty commitment. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/PS-P60-275-290W-c6de175de7ab.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | +50 W, cooler, +2.3 pp | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | +40 W, cooler, +2.1 pp | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | +45 W, +2.1 pp, +5 yr warranty | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | +45 W, cooler, +2.0 pp | | [Canadian Solar CS3K-325P](https://comparepv.com/panel/canadian-solar-cs3k-325p) | 325 W | +35 W, cooler, +1.8 pp | | [SunLink LNSK-330M](https://comparepv.com/panel/sunlink-lnsk-330m) | 330 W | +40 W, cooler, +1.7 pp | | [Canadian Solar CS3K-320P](https://comparepv.com/panel/canadian-solar-cs3k-320p) | 320 W | +30 W, cooler, +1.5 pp | | [Philadelphia Solar PS-P60-275](https://comparepv.com/panel/philadelphia-solar-ps-p60-275) | 275 W | -15 W, -0.9 pp | | [Philadelphia Solar PS-P60-280](https://comparepv.com/panel/philadelphia-solar-ps-p60-280) | 280 W | -10 W, -0.6 pp | | [Philadelphia Solar PS-P60-285](https://comparepv.com/panel/philadelphia-solar-ps-p60-285) | 285 W | -0.3 pp | | [Philadelphia Solar PS-M60(BF)-305](https://comparepv.com/panel/philadelphia-solar-ps-m60-bf-305) | 305 W | +15 W, cooler, +0.9 pp | | [Philadelphia Solar PS-M60-310W](https://comparepv.com/panel/philadelphia-solar-ps-m60-310w) | 310 W | +20 W, cooler, +1.2 pp | | [Philadelphia Solar PS-M60-315W](https://comparepv.com/panel/philadelphia-solar-ps-m60-315w) | 315 W | +25 W, cooler, +1.5 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +4.8 pp, +15 yr warranty | | [Lina Energy LEPV 400](https://comparepv.com/panel/lina-energy-lepv-400) | 400 W | +110 W, cooler, +4.5 pp | | [Phono Solar NS-360MH-60](https://comparepv.com/panel/phono-solar-ns-360mh-60) | 360 W | +70 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-p60-290 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
