trivial, do it wrong and you are out a lot of $.
The panels they use appear to me, NOT TO BE the common, most economical ($.75/watt USD) types
often used in grid tie systems. In getting the proper voltage & current combination for the motor, they
may have selected panels with several times the cost per watt. If you can engineer a system for the
cheapest panels, you stand some chance of beating their prices.
I have been known to obtain the service manual for equipment I'm interested in, and think about
what key components I could use for DIY.
Are you planning to remove snow from the panels in the winter? good luck, Bruce Roe
