    Do you think I could mount solar panels on 40 foot tall poles to get above the trees on my property?

      ... ridiculously expensive.

      For comparison, our pole ($350) is 10" in diameter, 18' long, 8' of which is under ground, and 10' above. The pole is filled with cement, and is centered in an 8' length of sonotube, also full of cement. Our cement mass is bigger than needed, because it's the minimum we could get delivered. This ensures it's not going anywhere under serious wind load (which we get at our elevation). The rack on which the panels are mounted is designed to for winds exceeding 80 mph.

      Extrapolating from that, you'd need something ungodly huge with a block of cement the size of a small building to anchor it, and probably guy wires. If you're looking to get power at that height, it becomes more sensible to start looking at the feasibility of small wind.

      Solar isn't going to be the right solution for every single location, and not every individual would need to install solar for us to drastically reduce our electricity-related carbon use.
