As sales climbed, First Solar filed for an IPO in November 2006. The stock went out at $20 and hit $200 within a year, a trajectory that compares with Google's first year. The economic calamity, among other factors, caused the stock to drop, but the company has consistently topped revenue and earnings expectations while dropping the average price of its solar panels. It broke the $1 per watt manufacturing cost barrier in 2008. During the second quarter, the cost per watt was down to 87 cents. But good luck figuring out how they do it – the company fiercely guards its secrets. First Solar is working on a way to bring copper indium gallium selenide (CIGS) cells to market.
