Tracking the Sun with Solar Electric Panels
Strawberry pickers at Fairwinds Farm in Oxford, Maine were greeted with more than just beautiful summer weather and luscious berries this summer: they had an opportunity to watch the installation of Maine’s first AllSun Tracker, installed and designed by ReVision Energy.
The tracker, a Series-20, features twenty 240-watt solar electric panels for a nameplate production rating of 4.8KW. The dual-axis tracker has a motor driven by GPS so that it follows the sun east-to-west and up-and-down to always capture the most solar resource available.
The tracker will produce roughly 30% more power than a fixed array of the same production capacity, and, in this case, is estimated to produce 8,500 kWh per year – roughly $1,300 worth of electricity. The system will produce 100% of the Farm’s current electric loads, and is sized to offset electric usage from a new electric water heater and the addition of an electric car.
“Now we have enough solar power to produce 100% of our electric bill plus the electric car" says Farm owner Dave Knightly. "With everything about oil being so uncertain, this gives us huge confidence for the future. We’re paying into it now, so we can save a bunch of money later.”
