This project was
conceived, designed, and constructed (with help) by Steve Heckeroth, who
is a pioneer in renewable energy, electric vehicles, and sustainable
living. Please see Steve’s
website. Steve is currently the director of building-integrated
photovoltaics for the Uni-Solar
is oriented exactly to solar south. The reinforced concrete posts were
formed and poured onsite. Photovoltaic panels are Uni-Solar
triple-junction amorphous silicon. They are adhered to structural
standing-seam roofing panels. Inverter is Trace (now Xantrex)
SW4024 4kW. Unit is grid-intertied (as is the rest of the PV systems
onsite) and supported by the State of California with yearly
All the electric cars and
tractors onsite (48V tractor dump-charged to 80% in 20 minutes with 2/0
cable) were charged with this unit.
My role in this project?
Though at the time I was heavily involved in the reconstruction of this
car. I did help do a few things. I installed the battery bank and
fabricated the cabling for it, (the 8V batteries were a temporary
install, left over from a car project) helped pull cable through
conduit, assembled some junction boxes and conduit, wire tied together
re-bar for the concrete forming process, and wired together some of the
PV panels at the junction box (always live when the sun is up!).
After seeing this system kick out 38A in a dense fog, I was sold on the capabilities of the triple-junction amorphous silicon panels.
