The glasshouse creates a protected surroundings to withstand the weather that can negatively impact reliability and efficiency of the photo voltaic thermal system. Prototypes of Fresnel lens concentrators have been produced for the gathering of thermal vitality by International Automated Systems. The SEGS is a set of 9 plants with a complete capability of 354 MW and has been the world's largest solar energy plant, each thermal and non-thermal, for many years. Heat in a solar thermal system is guided by 5 primary rules: heat acquire; heat transfer; heat storage; heat transport; and heat insulation. Solar thermal energy plants use heat exchangers which are designed for constant working conditions, to provide heat exchange. Copper heat exchangers are vital in solar thermal heating and cooling methods due to copper’s excessive thermal conductivity, resistance to atmospheric and water corrosion, sealing and becoming a member of by soldering, and mechanical strength. In January 2010, Stirling Energy Systems and Tessera Solar commissioned the first demonstration 1.5-megawatt power plant ("Maricopa Solar") using Stirling know-how in Peoria, Arizona. The new CSP-Stirling technology brings down LCOE to USD 0.02 in utility scale.
