solar vs wind... its a no brainer for me.
I have friends who live on the rim of Lake Billy Chinook (no grid power within MILES) and when they bought the place several years ago, all the neighbors who had been there for years all had/have wind turbines for power... after using a generator a couple years they decided to install a solar array .... they hired it done by a solar contractor, (its now been nearly15yrs ago) and they have been providing power for themselves and 2 other properties that are only occupied intermittently..... while the people with wind turbine as their only source, are still having to closely manage their power usage.... and the NOISE of wind turbines is irritating in a quiet setting, which I prefer to be QUIET....
(a lot of the people in the community have since converted to solar, some keeping the turbine, and others getting rid of it, which other neighbors take the used turbine equipment to increase the production of power, along side their existing turbine... )
this installation is where I got my introduction to solar power, and I can securely say that solar will always out perform wind power for the cost and longevity of the systems, unless one is in a location where the sun doesnt shine much.... wind turbine technology is at its peak, but I dont believe the technology of collecting and storing energy from the sun, is....
I have a place in arizona, east of kingman, that starting about now, thru to july or august, the wind blows HARD almost every afternoon for about 5-6 hours, but the sun shines for almost 10-11 hours during this time, so again, solar is going to be the most effective....
having BOTH could be useful in a lot of locations, but the noise isnt worth it to me, when a couple more "silent" panels could be added cheaper and easier....
the ONLY advantage of a wind turbine is that it can produce power well into the night, providing the wind continues to blow.... but this isnt very common or reliable in most places... the main disadvantages are, given that the wind DOES blow enough to operate it effectively, is the noise produced and the "absolutely necessary" required, timely maintenance, which will save the bearings and thrust bushings, that WILL fail if not kept lubricated...
