More 'turnkey' options for thermal solar
eSolar, which was created by Idealab, makes utility-scale thermal solar systems. It uses solar panels to transform light into electricity. These solar plants have heliostats that reflect sunlight to its centralized tower. The sunlight produces heat and creates steam, thus rotating the turbine that generates electricity. eSolar already has a significant list of projects in China and the Southwest of the U.S. But eSolar is not the only company using "turnkey" solar thermal option for utilities. In August 2009, Solar Trust acquired rights to about 726 megawatts worth of solar projects for Southern California Edison. It is designing, building, and installing the solar thermal plants. The two thermal plants are similar. Both Solar Trust and eSolar offer thermal solar solutions. However, a key different is that Solar Trust uses parabolic troughs to reflect sunlight and heat liquid for steam instead of heliostats.
