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.

What owners get
PID resistance

The use of PID-free EVA encapsulant minimizes power loss from potential-induced degradation, which matters in large arrays with high DC system voltage.

Salt mist and ammonia resistance

The construction is rated for aggressive environments, making the series a solid fit for coastal installations and agricultural sites (e.g., near livestock farms) where cheaper modules suffer faster frame corrosion and laminate degradation.

Low annual power decline (-0.7%/year)

The 25-year linear power warranty with an annual degradation of just -0.7% beats the standard -0.8% typical of comparable polycrystalline series from that era, resulting in higher cumulative energy yield over the module's lifetime.

BNEF Tier-1 manufacturer

Philadelphia Solar, operating since 2007, is listed as a Tier-1 manufacturer by BloombergNEF, confirming that its modules have been financed by at least six different non-recourse banks - a key factor for bankability in commercial and industrial projects.

Good low-irradiance performance

Cell design optimized for diffuse light conditions keeps output relatively stable in regions with heavy cloud cover, such as Central European climates.

Trade-offs
Discontinued production

The PS-P72-(330-345W) series, released in 2018, has been discontinued from the manufacturer's current lineup. 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.

Notes from the database
  • At 16.9% efficiency, this panel is 4.9pp below the database median of 21.8%
  • 169.4 W/m² power density is 48.7 W/m² below database median (218.1 W/m²) - requires larger installation area
  • -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
  • In the top 96% for efficiency among all N-type panels

About the PS-P72-(330-345W) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

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.
