SunEarth - Solar Panel Reviews

About SunEarth

Sun-Earth was a Chinese company established in 1966 and began producing PV modules in 1978. If not the first, it was among the first solar panel manufacturers in China.

Company Info

Formerly Ningbo Solar Electric Power Co., Ltd., Sun Earth Solar Power Co., Ltd switched to its "new" name in 2010. Its headquarters were located in the Hi-tech Zone, Ningbo, Zhejiang Province, China. The Ningbo facility covered 646,000 square metres and the company had several other manufacturing locations. 

A vertically-integrated operation, Sun-Earth produced polycrystalline silicon materials, silicon wafers, solar cells, modules, controllers and even inverters.

Why Sun-Earth ceased operations and when isn't clear, but their website (aside from a contact page), has been offline for some years.

Sun-Earth Solar Panels In Australia

There were many models of Sun-Earth solar panels available in Australia, from 80W capacity to 290W; and in polycrystalline and monocrystalline formats. It appears Sun-Earth was one of the first companies to offer a positive power tolerance. While many manufacturers promised actual power output would be plus or minus a few watts of the nameplate rating, Sun-Earth was 0 to + 5%.

Some of the company's panels had four bypass diodes, which helped improve output in partial shading situations.

Sun-Earth 250 Watt solar panels boasted 14.7% efficiency and temperature coefficient of Pmax of -0.45% /°C. These panels measured 1065 mm x 1596 mm x 46 mm and weighed 20.5kg.

Warranty Details

Sun-Earth offered a 10-year product warranty and 25-year performance warranty. The performance warranty guaranteed power output at 10 years of at least 90% of nameplate rating, and out to 25 years at a minimum 80%.

If you've come to this page looking for information on how to make a Sun-Earth warranty claim, we suggest you contact the company that sold you the panels if they are still around. If they aren't, try the contact form on the Sun-Earth web site; but don't reveal any sensitive details as we're not even sure if that form is for the same company any more.
