Filling my electric tank with zero carbon produced electronsTo plug into a coal burning utility grid, sort of reduces the advantages to having a booster battery. I had some solar panels and decided to use them for keeping my batteries charged. I wanted to make simple easy to construct mount for the panels that would be in close proximity to the car in the garage.
I made stainless steel mounting brackets and attached them to each of the 8-50W panels both top and bottom. I screwed the top brackets right into the T-111 siding, and the bottoms to a fir strip 2" X 1.5 ". The angle was set with two wooden standoffs. The DC from the panels is 75V @ ~6A. The solar charge controller is a simple op amp servo circuit set up to turn off the charge when the voltage on the pack gets to a set voltage. The AC charger is a Vicor DC/DC batmod, powered from rectified and filtered AC. A simple flip of a switch switches from one to another.
First EV range test.
23 miles 45% charge remaining, average speed 28 MPH.
It works yea!
