I have ideas to build a solar space heater, water heater, wind turbine, and PV array.
Lot's of great DIY projects there. I just glanced through a few of the DIY PV panel projects, and I would say don't follow them. Plywood isn't really a good material for panels because moisture can get in. Approach it in a way to reasonably expect a 20yr+ service life, for which plywood isn't acceptable outdoors. I'll share what Harold and I think are the best links once we finalize our approaches.
We have direct burial plywood which is soaked in preservative (poison) and I have some in the wet ground over 25 years with no sign of service life problems. I have similarly treated pine garden ties, some of which have rotted away in 6 years.
You have to get Harold to genetically modify his balsa to be fungi proof.
