Year round renewable energy?

[bigpaul]

the problem with any renewable energy system is not so much the main unit, that may last 25, 30 years-it may last forever, but its the little stuff like connectors and inverters and relays, how are you going to replace or repair them when they fail, can you even repair these things even if you had the skills to do so? or do you need a container full of spare parts to keep it running for the next 30-40 years, if the production line shuts down because of economic failure(or some other reason) getting spare parts may not be easy, sure there might be a s...load of parts lying about post SHTF but you wont be the only one looking for them.
