TdS Report #30: Team Profile: Solar Black Bear, Phantom Sol
This is Ceara McNally's first year with the UMaine Solar Vehicle Team. She is
a year from finishing up her Engineering Physics double major at the University
of Maine.
First we talked about the Solar Black Bear, a pickup truck that carries a large
solar panel on top. "Last year we had a 1 kiloWatt array but we doubled it to
a 2 kiloWatt array." 12 panels are wired as 2 strings that are then wired in
parallel. The main string is permanently attached to the truck, mounted on a
framework that starts at the cab roof and runs back over the bed, sloping down
towards the rear. (In previous years the array was parallel to the road and
mounted a bit higher. I suspect this layout reduces drag.) The second string
panels are removed and stored on the bed of the truck when not in use. Setting
up the second string panels is a multi-person job, requiring holding them in
position while quick-release pins are inserted. The panel runs at 216 Volts.
The team is disappointed that the Tour de Sol eliminated the Commuter category.
"The Solar Black Bear won that for the past 3 years. I think that MIT won that
3 years in a row. We were hoping to get 4 years in a row to beat them."
We then went on to look at the Phantom Sol. It also started life as a pickup
truck, but you wouldn't guess that by looking at it now. It is low, low to the
ground with an aerodynamic body that just slips through the air. She opened
the rear battery access panel. "We use to have foam box covers. Before you
couldn't access the batteries without taking the whole body off." The car has
2 strings of 20 8-Volt blocks, wired in parallel. They feed a Raptor 1200 Amp
controller. "At full open it draws 600 amps from each pack," said Jeff
Bartosiewicz.
Jeff told me that getting to the Tour had its exciting moments. "Two weeks
before the Tour the Solar Black Bear had a voltage leakage that proved to be in
the motor. So we had to run out, get a new motor, replace it, had trouble
getting the clutch back in right, and the drive 200 miles before coming here."
The 200 miles is a Tour requirement. "It was a week of no sleep, right before
finals."

Program blurb The Solar Black Bear returns for its fourth year
to defend its three consecutive first place
finishes in the Solar Category. New this year is
a completely new solar array, motor controller,
truck bed and dashboard system. The new designs
are aimed at improving reliability and
practicality, while keeping the Solar Black Bear
a cost-effective solar transportation solution.
