Solar Power Plant which provides energy even at night

There is new installed demo project in Hawaii. It’s been installed by Keahole Solar Power. The installation of Sopogy Micro-scale Concentrating Solar Power Concentrators was done on Big Island (Hawaii).
The installation:

• Thousand solar collectors.
• Surface area -  3.8 acres.
• Thermal energy – 2 megawatts. 

 

So there is 8,000 gallons of water heated through Electratherm “green machines”- The ElectraTherm units are called Waste Heat Generators and run on a temperature difference 20 degrees.
The result: according to Keahole, “firm, fixed power which has been deemed as the holy grail for renewable energy.”
