Trina Solar has been recognized in Newsweek magazine, TIME magazine, and other major news outlets and solar equipment review sites.

SunPower Corp

SunPower is one of the leading and most reputed solar panel and solar energy product company, now owns both the photovoltaic and solar thermal power business of SunPower.

The company’s products are dedicated to providing a variety of solar panels that are either for the residential use or the commercial use.

SunPower corporation was actually incorporated in 1990 but went public in 1995.

Just like in the case of most publicly held businesses that are oriented towards solar energy, the company started off by manufacturing solar cells and was later on joined by the solar panels.

During this time, the company even had to face a couple of roadblocks but it was finally successful in settling the debts and has been making a lot of profit since then.

The company is currently headed by Dr. Tom Werner, who had been with the company since 2005.
