Saturday was the Solar Tour I talked about
here, and Matt and I only managed to see 4 houses out of the 7 I had mapped out for us. Oh yes, I google-mapped our tour and if it weren't for the fact that we were searching for crumbs on the car seats to sustain us just another hour or two, we would have made it.
But the 4 houses we did see were all very unique and we walked away with a lot of ideas and thoughts on the subject of solar. First off, there are 2 types of panels we saw throughout --
PV panels that harness energy for electricity, and
Solar water panels that heat the water in your house.
House 1:
This guy did everything himself and since he has such a large lot (unincorporated as well), he built all his solar water panels and PV panels on his lot as opposed to a roof. He has 11 solar water heater panels! He's only on the grid as backup and it's mostly for the winter. And he has back up battery (10, I think) storage for the evening/cloudy days.

ouse 2:They just did the solar water panels - 4 of them - on their roof. The owners weren't around but a nice guy from
illinoissolar was and he told us about it. I think $40,000 was the amount that a solar water system would cost. OUCH. But he said that
IL and the US government both have rebates and tax incentives that help offset the cost, and then in some cases you're cutting your bills in half ... so, there's some give and take. But it takes a few years to reap the initial costs. He builds electric cars and told us the Prius was awesome. Just another dilemma: Prius or Solar Panels?
House 3:
Now this house was SPECIAL. And I'll talk more about this here on
Rosemarie's Garden because it was more than just solar PV panels ... we're talking green roof, complete native Illinois prairie habitat, passive solar design house. Wow. Right in the middle of the suburbs. A true oasis.
House 4:
This one most closely resembled what we'd like to do for our house. They started with the solar water panels (installed by professionals). The owners said they saw an immediate return. Then they added solar PV panels on their own. So they have both on their (very large) roof. They don't have battery storage so the house runs on solar during the day (sunny times) and then works on the grid the other times, but they harness enough power that they don't use to sell back to their town. In this case, their meter gets turned backwards and they get money back from whomever is buying the energy.
So now that we've taken the tour, we went back home to look at our very odd shaped and tiny rooflines and wonder if we can even do this? The cost is a big factor so we would really have to invesitage the rebate/tax break issue.
