I’m part of the a farm energy working group. The group contains folks from power companies, alternative energy companies, education, farmers, and some others. As part of today’s meeting, we visited a number of solar arrays and wind turbines near Kalona.
This is 3.6 kW 20 panel flat array. It averages about 500 kWh per month and cost the installer about $20,000 (he did the installation himself).
Here’s the controller, inverter and meter for the system. Wouldn’t his be a nice complement to a wind turbine!
