About product

SS8-72HD-550M is a model that uses a number of technologies to bring durability and performance to the next level. 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.

Another advantage is the half-cut cell technology. SS8-72HD-550M has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. The efficiency of this model reaches 21.29% — well above the market’s average. 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 offers 12 years of product warranty and guarantees 84.95% of original performance after 30 years of operation.

Increased efficiency of up to 21.29%

SS8-72HD-550M ensures maximum power production. 21.29 percent module efficiency is achieved using PERC technology and a powerful antireflective coating. This is much greater than the norm, resulting in significant additional savings throughout the years of operation.

Keeping cool in hot weather

Even at high temperatures, SS8-72HD-550M remains efficient. It loses just -0.334% efficiency for every 1.8°F over 77°F, letting you make the most of the sunniest hours.

Quality and reliability

SS8-72HD-550M undergoes various quality checks during the production process and is subjected to serious quality and reliability testing. Manufacturing facilities are highly automated, removing the possibility of human errors. SolarSpace is committed to quality, safety, and dependability to ensure you get the finest.

Low degradation for a longer lifespan

These panels will lose no more than 2% of their power output in the first year of service. From the 2nd year to the 30th year, the average annual power decline will be no more than 0.45%. The module retains over 84.95% of its original output after 30 years. Guaranteed by SolarSpace.

Certified for the worst environmental conditions

SS8-72HD-550M is PID, salt, acid, and ammonia resistant. It can also bear mechanical loads of up to 5400 Pa on the front and 2400 Pa on the back. This durability is mostly owing to the 1.18" thick anodized aluminum alloy frame and a layer of protective glass.
