The following links are drawings of specific systems or home-built equipment.  The schematic for the electrical generation systems is in the Home Power article.

I had to build meters to test the PV modules and to measure wind DC kWh.

There are piping diagrams for the various solar heating systems, including radiant floor, the craft room, the train room, the primary and secondary loops for the domestic hot water and therapy pool.  All numbered valves have tags with appropriate information.

We have a control system to deploy an awning over some of the solar heating panels to prevent overheating in the summer.

We use a whole house reverse osmosis (RO) system to remove most of the CaC0₃ from the well water (significantly reduces the amount of cleaning required for washed surfaces).  We mix some well water back into the RO output to prevent corrosion of the copper pipes.  There is an alarm system to monitor when RO membrane cleaning is required and to require a manual reset of the RO pump if there is ever low pressure (other wise damage can occur if the RO pump oscillates on/off with the well pressure).
