First Solar acquired TetraSun for their high efficient solar cell technology.
First Solar had primarily been constrained to large utility-scale projects, which was in line with the growth areas in the industry. The solar PV industry is now moving towards a decentralized model, which is seeing solar installed at the point of consumption, leading to growth in the residential, commercial, and industrial rooftop markets. According to TetraSun's website, the company has demonstrated greater than 20% efficiency in mono-crystalline solar cells by using its first-generation low-cost cell architecture. Today, it is manufacturing solar cells with efficiencies in excess of 21%, targeting 24%. Prior to First Solar's acquisition of TetraSun, it was a fourteen-employee start-up with $12million from investors. It is now expected to ramp up annual production of crystalline modules at 100MW, which will integrate these advanced high-efficiency cells in the second half of 2014. This increase will allow First Solar to break into markets where it is not presently active. First Solar will be able to target the emerging residential, commercial, and industrial rooftop markets through lower installation costs, faster installation time, and greater system revenues through higher efficiencies targeting space-constrained installations.
