Suntech Holdings, which is the world’s largest solar panel manufacturer, now offers a 300-watt (0.3 kW) solar panel for utility-scale power plants (power plants that are usually upwards of tens of millions of watts), as well as commercial-scale solar power projects (powering office buildings is an example of commercial use). The solar panel is available in North and South American markets.
The new module is called the Ve-series, and it consists of 72 solar cells and has a 15.5% module efficiency. The frame design was said to have improved. It also received 1000V (volt) certification from UL (Underwriters Laboratories), which is a very established safety certification organization.
The improved module design is actually 10mm thinner and 2.6 pounds lighter than the older 50mm modules. These weight reductions reduce shipping costs considerably. The thinner module design will also reduce handling, packaging, and storage costs.
The module is certified to withstand wind-induced forces of 3,800 pascals (Pa, or 3.8 kPa) (equivalent to a wind speed of 176 mph), and snow-induced stress of 5,800 pascals.
With the UL1000V certification, Suntech’s 300W modules can be safely connected in longer string series than allowed by the earlier 600V industry standard.
A pallet of the new Ve-series modules produces 19% more power than a pallet of it’s previous modules. Like Suntech’s entire U.S. product portfolio, the new 300W Ve-Series product will not be subject to the recent U.S. import tariffs imposed on solar cells produced in China.
