Solar panel. at what age does output diminish?

Question

At what age do solar panels power diminish drastically? Or does it depend on the maker and other technical variables?

Also, how do I rate the other wiring and adapters to match the solar panel?

Answer 1

U must keep them clean. It drops off very little ,the main problem is the storage batteries as they loose the it efficiency. We have solar panels on satellites that have up there for many years. There is another thing and that is to mount them for winds of 100 mph. Also each panel should flow through a fuse so that if one shorts out it will not burn up the system.
