Vehicle Name: Solar Black Bear Vehicle Number: 20 Team Name: U. Maine Solar Vehicle Team State: Maine Electric: 1986 Chevy S-10 conversion, (Solar + Battery: Trojan PbA)The Solar Black Bear was created in the spring of 1999 and has been the Light-duty two-person Solar Commuter Champion for 6 years. The Solar Black Bear is a very practical and usable vehicle that demonstrates the team's enthusiasm and commitment to creating a better tomorrow for today.
The mechanism that tilts the array is simple, but clever and effective.
There are four posts that support the under-frame of the array, which has pivot
pins on both sides.
Here we see the two driver's side pins have been pulled so the array is tilted
on the passenger's side pins.
The silver electric lift cylinder at the front of the load bed (just above the
word "SCIENCE" pushes up at the center of the solar array, so the angle can be
set just so.
As the day progresses and the sun rises higher, the cylinder lowers the array
until, at noon, it is flat on the under-frame.
Put in the driver's side pins, pull the others and push up with the cylinder to
track the sun down to the west.
The batteries are all below the diamond plate load bed.
The diamond plate comes off easily for easy access.
