SunPower made a spectacular market début yesterday on the Nasdaq, making a 41 percent jump from its opening share price of $18 to $25.45 a share at the market close.

SunPower Corporation designs, manufactures and sells high efficiency solar cells and solar panels that generate electricity from sunlight for residential, commercial and remote power applications. What makes them different is their proprietary all back contact silicon solar cell technology, which they claim produces up to 50% more power per square foot compared to conventional solar cells.

For this you can read 20% efficiency.

Small by solar standards, the company has capacity for 25 MW per year and the plant is based in the Philippines but could expand to 100 MW.

Looks like a nice little earner for Cypress Semiconductor.
