Cleantech's solar array will be seven times larger than the next closest rival

Portugal announced in April that it was home to one of the world's largest solar arrays. The 150 acre, 11-megawatt (MW) solar plant was built by Catavento and PowerLight Corporation and is capable of powering 8,000 homes in Serpa.

Cleantech America LLC., a San Francisco-based company, plans to build a solar farm that would far eclipse the one built in Portugal. The new 80 MW farm, known as the Kings River Conservation District Community Choice Solar Farm, will be situated on 640 acres of land and is scheduled to be completed by 2011.

"We're pretty confident that solar farms on this scale are going to have an industry-changing impact," said Cleantech CEO Bill Barnes. "We think it's the wave of the future. This scale of project, I think, creates a tipping point for renewable energy."

"We think the impact for it will be similar to the impact of the computer chip," Barnes continued. "So too will economies of scale like the Community Choice farm drive down the cost of solar."

Cleantech estimates that the energy generated by the solar array will be enough to power 20,000 homes.

RE: 640 acres is a lot of land

Photovoltaic Solar Panels are not econonomical in several ways (already mentioned by others). Solar furnaces require glass&metal not silicon, and are a lot more economical. 640acres would recieve about 2900MW peak solar energy. Less than 2.8% (80M) of this will be harnessed by the specified solar array taking up equivalent of ?% of the land (each panel is <100% covered by solar cells, panels are spaced apart). Solar furnace can be >3x more efficient than standard solar panels.
Remember that land in a dessert is cheaper and already is under utilised (low use by nature and humans). What is regarded as desserts frequently have some vegitation but low importance in the scheme of things.

One problem with solar panels on the suburban roof is then being shadowed by taller buildings and trees.
