Potential for more?

摘要

Throughout the EU, only 40 megawatt-class collector arrays are in operation. However, examples in use show that very low solar thermal energy costs can be reached.Small solar energy systems on the roofs of single-family homes are synonymous with so-lar thermal energy use in Europe today. Only 1 % of the collector surface area is accounted for by large-scale solar energy systems with collector sur-face areas greater than 500 m~2.
