Suntech STP255S-20/Wdb Review

Author by

PROS / There is little or no maintenance with these solar panels. If you choose, you can rinse them with water or just wait for rain to clean them.

CONS / You have few options for contacting the company if you have questions.

 VERDICT / Suntech gives you good durability, an unusual but lengthy warranty on power output and easy maintenance. Unfortunately, contacting the company is not as simple as it could be.

You get durability with Suntech STP255S-20/Wdb solar panels, which can withstand a covering of snow weighing 113 pounds per square foot. In addition, these sleek black monocrystalline solar panels can generate a solar efficiency of 15.7 percent, which is a fairly healthy figure in the industry.

The Suntech STP255S-20/Wdb solar panels can withstand temperatures of 40 degrees below zero and up to 185 degrees F.

With these Suntech solar panels, you get a somewhat unorthodox warranty that is different from the standard guarantees on workmanship and power output, which generally are 10 years and 25 years, respectively.

Instead, you get a 10-year warranty on workmanship with these solar panels. As far as power output, Suntech’s warranty states it will cover the panels for five years ensuring 95 percent of their original power output, for 12 years at 90 percent power output and 18 years at 85 percent. Suntech’s warranty provides 25 years of coverage at 80 percent power output.

This Suntech solar panel model offers you relatively standard dimensions of 64.56 inches in length, 39.06 inches in width and 1.37 inches in depth. Each of these panels weighs 40 pounds, which is the lightest of the panels in our product lineup.

If you have questions, you can contact the company by phone or email. Unfortunately, there is no live chat option or company blog for more information, which is unfortunate since Suntech has been a force within the solar industry since its inception in 2001 and by now has established a worldwide presence in the solar market.

Summary

Suntech Power is well known worldwide for its solar panel innovation. The Suntech STP255S-20/Wdb solar panels give you an unusual but lengthy warranty, a healthy solar efficiency percentage and good durability. One drawback is the relatively limited contact you get with the manufacturer.
