The next question inevitably is… “so, how much did they really produce??”. Between April 20, 2010 when the trackers went online, and April 20, 2011 they pumped out 37,367 kWh – pretty close to our original projections! (You can check out the production day by day on the AER website at: http://www.allearthrenewables.com/energy-production-report/detail/163).
This is enough electricity to supply 74% of the demand for our main building (just over 50,000 kWh last year).
So what’s next? This year we’re hoping for more sunny days :) but we’re also looking hard at what we can do to reduce our electricity loads—remember, conservation always comes before efficiency and renewables. We’re working with folks from Efficiency Vermont and the Mad River Valley Localvolts to install a TED energy monitor so we can track our consumption patterns more closely and identify trends over time. We’re also using a Kill-a-watt meter to identify energy-sucking appliances and tools so we can plan future upgrades. And thanks to great state incentives, we’re also testing out some new LED light bulbs around different parts of the campus and looking into occupancy and daylighting sensors.
