How large dose a large-scale system need to be?

摘要

Individual planning of the necessary collector area is unavoidable when building a large-scale solar system. Simulation programmes alleviate the planner from the need to perform calculations, but an understanding of the underlying principles is nevertheless important. Small-scale solar systems providing hot water heating for private households are available as complete packages in many different sizes and variants. Complete solutions for 3, 4 and 5 person households, using vacuum tube or flat plate collectors, are available.
