Ok, nutshell version. Would like to be able to heat the home, possibly water, and have electricity even when power company doesn't. Would
eventually like to be completely off grid, but not sure what that entails or even if it's legal where I live. Trying to do as must reading as I
possibly can, but tutorials very quickly become too complicated for us to follow as far as DIY solar panel installation and DIY wind turbines. ANY
advice, direction would be appreciated.
Well I know a lot about this since I'm an architect and LEED accredited professional. First of all, the "payback" is still extremely long for these
technologies. It'll be 15+ years before you break even on the investment. And the government is doing a truly sorry job with incentives, there are
few. Second, it's not advisable to go off-grid. Solar panels create the most energy during the day when families are at work and school, so the only
way to "bank" that energy is to sell it back to the grid (battery storage is currently not a viable option for home applications). This requires a
meter that can run in reverse (not available in all areas, make sure you check). When the family is home in the evening they're buying power back
from the grid because the panels are not generating anything, but it's sold to the grid all day when they're not there. If you live in an area that
has variable energy costs this is really beneficial because you're selling energy to the grid during high rate periods and buying it back during low
rate periods. Wind generators operate in much the same manner.
Don't expect to cover 100% of your utility costs unless your house is incredibly efficient, the size of the solar array would be large and costly.
It's more reasonable to expect to reduce your bills by 50% or so.
HOAs are still a problem, particularly with wind generators. Check your local covenants (if any).
I don't recommend you try to go DIY on this, these systems are quite complex and the hookups are dangerous and it is best left to experts in the
field.
Another tech you might consider (especially if you heat with electricity) is geothermal heating/ cooling, it is very efficient. Up-front costs are 3
to 4 times a conventional system and payback is still a good 10 years, but it will make a big dent in your electric bill.
Also look at other ways to improve your home's efficiency- windows, attic insulation, Energy Star appliances, a programmable thermostat, etc. Many of
these are quite cost effective and payback is shorter.
