Most people are building systems large enough to keep them in tier 1 power usage (monthly power bill ~$10-$30). Over building the system to feed the grid isn't worth it because the power company will only pay $.04 per KW. So the return on investment isn't worth over building the system.
I am building a system for the pool at my parents house. the pump will be solar powered (saving $100/month). Since it's a pump and direct drive there are no batteries required and no licensed electrician required to connect the system.
I have been looking into it based on several friends of mine seeing major returns, low maintenance (panels must be cleaned), and relatively low cost.
There are a bunch of kick backs that help mitigate the initial cost also.
P.S. Wind turbines are in jeopardy. High maintenance cost makes the $/KW number not work. Hippies are going to start attacking them since their are some "videos" of birds getting whacked. They can fail catastrophically (that's a fancy word for suddenly for the dumb fucks with rusty cars) too.

Keep me posted on your solar projects. Since the kind of stuff I'm interested in is off grid, no fucks are given about licensed electricians, proofed drawings etc. (But I'm not a redneck with a death wish either.) I've heard of some DIY getting down to below $1/watt. I think most modern cells are still loosing about 1%/year in efficiency, but that's not too bad. There's some other solar tech that's being downsized from commercial, but it will be many years before it's available for houses.
My grandpa is an engineer from the aerospace days. He and a buddy are rigging up solar powered pool pumps too.
Windmills are mixed bag. On the upside, a small installation can put out many kilowatts if it's properly located in a wind corridor. This site would be perfect *most* of the year. But it has Santa Anas a couple times a year, absolutely requiring the blade be locked. I think the catastrophic failures, TMK, are almost all because of one point of failure with a particular bearing in the design, that just receives constant high stress. It's being improved too. But yeah, in a desert site like the one I have, solar exposure is pretty much year round, no obstructions and there's plenty of surface area.
The best you can do in site designs like this, but is very rare to have access is micro-hyrdo. Super efficient large amounts of power through small systems that are very durable. There just aren't many places with a nice stream and a good fall.
