About product

SS8-54HSB is part of the 400-M Series — one of the most recent made by SolarSpace. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.

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 SS8-54HSB two times smaller than the standard size, thus reducing power loss and improving low-light behavior. As a result, the panel achieves an impressive efficiency of 20.48%. SolarSpace offers 12 years of product warranty and guarantees 84.08% of original performance after 25 years of operation.

  • 400 W power output
  • 108 half-cut PERC cells
  • 20.48% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 25-year performance warranties

High efficiency of 20.48%

SolarSpace 400-M panels take full advantage of the company’s technologies that have won SolarSpace multiple awards. This PERC option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

Exceptional performance in scorching weather

At high working temperatures, a low temperature coefficient equals increased energy generation. Every 1.8°F over 77°F results in a model's efficiency loss of just -0.33 percent.

Quality and reliability

SS8-54HSB 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

SolarSpace guarantees limited degradation over the ensuing 25 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.58% yearly after that. After the 25 years are over, your modules will still show at least 84.08% of nominal capacity. A substantial 12-year product warranty is also included with this 400 W SolarSpace solar panel.

Enhanced frame design

SS8-54HSB design makes it ideal for residential and commercial rooftops. Strong 1.18" frame made from aluminum alloy increases durability and strength. The model can support a heavy snow load up to 5400 Pa. The back of the panel can handle 2400 Pa, ensuring that your system will survive the strongest of winds.
