What do you mean by a solar setup? Do you mean using actually sunlight instead of electrical lighting or do you mean using solar cells to power your equiptment. Solar cells are not yet cost effective. I too think the idea of photovoltaics is pretty cool but right now the efficiencies aren't there. They only make sense to use for remote power (like light houses and satellites).
Make it idiot proof and someone will just make a better idiot.
