SunPower Corporation, a solar technology and energy services provider, announced that it has signed multiple supply agreements with Ecomax Japan Inc. to purchase SunPower Corporation's high efficiency E20/327 solar panels totaling 20-megawatts (MW). In 2014, Ecomax plans to install the solar panels at several locations in Central and Northern Japan.

Acting as EPC (engineering, procurement and construction), Ecomax will construct multiple mega solar power plants in Gunma, totaling 13 MW for its customer, Farmdo, a company dedicated to assisting farmers and supporting agriculture in Japan. With the remaining 7 MW, Ecomax will build and operate solar installations and plans to sell the energy to local utility companies. It will also own 3 MW as an IPP (Independent Power Producer).

Ecomax has signed an extension to the existing solar panel purchase agreement with SunPower Corporation and will continue to buy the E20/327 solar panels for its future installations.

Integrated into the E20/327 solar panels by SunPower Corporation are its Maxeon® all-back contact solar cells. These cells are built on a solid copper foundation, making them extremely resistant to cracking, corrosion and stresses from temperature variation. With an efficiency of 20.1 percent, the E20/327 panels deliver more power in the same amount of space and maximize system output with fewer panels installed.

The company's solar panels are backed by the company's straightforward 25-year combined product and power warranty. It offers the industry's lowest power degradation with more warranted energy, resulting in an unprecedented 87 percent power level at the end of 25 years.

Solar products by SunPower Corporation are branded under the Maxeon® Solar name in Japan. The capacity of mega solar power plants in this release is described in approximate megawatts on a direct current (dc) basis unless otherwise noted.
