About product

Suntech Power STP370S-B60 is a PV module fit for both residential and commercial applications. Suntech Power engineers made the Ultra S Mini series durable and efficient, while minimizing the amount of useful space required for their operation. 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. Suntech Power made solar cells in STP370S-B60 two times smaller than the standard size, thus reducing power loss and improving low-light behavior. The efficiency of this model reaches 20.3% — well above the market’s average. The innovations made the appearance of the panel as impressive as the specs. A mere 1.4" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. Suntech Power offers 12 years of product warranty and guarantees 84.8% of original performance after 25 years of operation.

  • 120 half-cut PERC cells
  • 370 W nameplate capacity
  • 20.3% efficiency
  • 1000 V DC maximum system voltage
  • MC4 compatible connectors
  • 12 year of product and 25 year of performance warranty

More power and efficiency

An already high efficiency of 20.3% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, STP370S-B60 outputs 370 W of power.



Keeping the cool in high temperatures

STP370S-B60 manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just 0.36% in efficiency, allowing you to make the most of the sunniest hours.

High quality standards

Suntech Power strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.


Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by Suntech Power. The performance will decrease no more than 2% during the first year and then will be limited to 0.55% annually. Your modules will retain at least 84.8% of original performance after the 25 years are over. This 370 W Suntech Power solar panel also comes with a generous 12-year product warranty.

Enhanced frame design

STP370S-B60 design makes it ideal for residential and commercial rooftops. Strong 1.4" frame made from anodized aluminum increases durability and strength. The model can support a heavy snow load up to 5400 Pa. The back of the panel can handle 3800 Pa, ensuring that your system will survive the strongest of winds.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Suntech Power engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.

I’ve had exactly zero problems with ordering or delivery. These panels appear to function really well. Especially on hot sunny days. Fantastic performance in June. It will be interesting to see how they do this summer.

The other manufacturers will need to jump on board as soon as possible because these Suntech whole black panels look so hot. I've been REALLY pleased with the performance thus far, considering it’s a "cheap" panel.

How do the Chinese manage to produce panels with good specs so cheaply?

We believe it’s a topic for an article. The short answer: Chinese companies use local suppliers and have built great infrastructure over the years.
Didn’t Suntech go bankrupt like in 2010?

It happened in 2013, but it was acquired by another company in 2014. Now Suntech Power is a Tier 1 solar manufacturer.
