- "solar panels don't fail - nor do wind turbines."
Wake the hell up. If the battery goes flat, the sun isn't shining or the wind doesn't blow then there is no power. THAT makes them unreliable. Right now I have a solar hot water system that hasn't got HOT water. Lucky that there is a power back up and it can be relied on because of coal fired powerstill being available.
it is YOU that is unreliable ------- incapable of imagination, vision and basic engineering and planning.!
