Philadelphia Nexus 600W Bifacial Panel

The Philadelphia Solar Nexus PS-MNB144(HCBF)-600W is a high-efficiency bifacial module made in Jordan on automated robotic production lines. It has 144 half-cut monocrystalline N-type cells (72 x 2) with a 16-busbar layout. It delivers 600 W at standard test conditions with module efficiency up to 23.23%, and its power tolerance is positive only, from 0 to +3%.

Unlike a standard panel, the Nexus produces power from both faces. The front uses 3.2 mm tempered anti-reflective glass, and the transparent backsheet lets the rear of the cells capture light reflected from the ground or roof. The bifaciality ratio is 80% (+/-5). Philadelphia Solar rates the extra output at 5-25%, depending on ground reflectivity (albedo) and mounting height. White roofs, light gravel and sandy ground under elevated structures give the best gains.

The module is built for hot, dusty climates like Iraq's. Its power temperature coefficient of -0.29%/C limits output loss in summer heat. It is certified for dust and sand resistance (IEC 60068), salt mist (IEC 61701), ammonia (IEC 62716) and PID resistance (IEC TS 62804). It is rated for 5400 Pa front and 2400 Pa rear static loads. The 1500 V maximum system voltage allows long strings, which suits on-grid rooftops, off-grid and hybrid systems, and utility-scale solar farms.

Philadelphia Solar backs the module with a 12-year product warranty and a 30-year linear power warranty. Annual degradation is capped at -0.4%, so the panel keeps at least 94.6% of its rated power after 12 years and 87.4% after 30 years.
