SunPower (SPWRA) announced early this morning a new contract with City Solar of Germany in which SPWRA will provide them with 100MW of solar panels along with commercial rooftop and ground mounted systems over the next 3 years.

Steffen Kammler, City Solar’s President and Chief Executive Officer, said, “With this deal, we can offer our commercial customers SunPower’s high-efficiency solar panels and patented rooftop and ground mounted tracking systems, which can significantly increase their energy output.”

The news didn’t help SunPower any today as the stock was battered along with the rest of the market, finishing down nearly 18% and looking to test the lows around 20 in the coming days.
