SolarSpace 540W Solar Panel 144 Cells SS8-72HD-540-M Commercial 620 panels per Container

SS8-72HD is part of the 540-M Series — one of the most recent made by SolarSpace. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. SolarSpace made solar cells in SS8-72HD two times smaller than the standard size, thus reducing power loss and improving low-light behavior. Not surprisingly, the efficiency of this module is quite high – 20.9%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. SolarSpace paid as much attention to durability as they did to performance. SS8-72HD is guaranteed to retain at least 84.8% of output after 25 years. Product warranty for this panel lasts 12 years.

• 540 W power output
• 144 half-cut PERC cells
• 20.9% efficiency
• 1500 V DC maximum system voltage
• MC4 connectors
• 12-year product and 25-year performance warranties

More energy and efficiency

The PERC technology further improves an already excellent efficiency of 20.9 percent. A reliable PID resistance and a unique glass lamination were added by the maker, which ultimately produced a model that was effective and extremely durable. SS8-72HD produces 540 W of power under typical test settings.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. SS8-72HD loses just -0.33% of efficiency for every 1.8°F above 77°F.

Quality and reliability

SS8-72HD is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by SolarSpace. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 84.8% of original performance after the 25 years are over. This 540 W SolarSpace solar panel also comes with a generous 12-year product warranty.

A panel that can handle hail, wind and snow

The 1.38" frame built of aluminum alloy and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.
