Though it won’t be completed until 2010, and its overall capacity will be divided across several sites, SolFocus has announced that it has signed a deal with EMPE Solar worth $103 million that will install over 10 megawatts of CPV power at sites in southern Spain. SolFocus says that the project will create enough electricity for a city of about 40,000 people. While the company claims it as being the largest CPV project in Europe, Greentech Media points out that it will be the largest in the world.
In case you’re not familiar with how concentrating solar PV works (and there a number of companies working on variations on the technology), this is how SolFocus touts its technology:‘Highest Energy Density of Any Solar-Energy System’
SolFocus CPV systems are designed to deliver the lowest Levelized Cost of Energy (LCOE) and the highest energy density of any solar-energy generating systems. By concentrating sunlight using innovative optics onto a small area of high-efficiency solar cell material, SolFocus systems dramatically reduce the amount of expensive and often supply-constrained solar material used in the system. The multi-junction solar cells incorporated into the system provide the highest levels of efficiency in converting light to electricity. These cells also offer the benefit of not being impacted by high temperatures which cause dramatic degradation of performance in other systems such as silicon PV and thin film cells. The largest portion of the SolFocus systems is glass and aluminum which are readily available and have proven field durability.
The SolFocus CPV panels are mounted on a dual-axis tracker that maintains the alignment of the optics with the sun.
Sol Focus also has recently completed to smaller projects in Spain for the Institute of Concentration Photovoltaic Systems; one of the two 500 kW projects came online last week and the second should be grid connected in two weeks. (Greentech Media)
