Can the mirrors withstand the harsh desert conditions and sandstorms?
Solar-thermal power plants have been operating in the Mojave Desert for over 20 years and have withstood hailstorms, sandstorms and cyclones. In the event of impending danger, the mirrors, which are rotatable, can be positioned in such a manner that they are protected. Should the mirrors break nonetheless (0.4% per year), replacements are part of the operating costs. Signs of wear and tear on the mirrors in Kramer Junction have not been an issue for the last 20 years. Today, the power plants work more efficiently as operating and maintenance methods are now better than when operations began.
