For the first full six months of their operation, the 18 solar photovoltaic panels at the Southbury library have been performing as shown in the chart below:
January and February were below expectation due to the numerous storms and heavy cloud cover associated with the “Polar Vortex.”
However, at current electricity costs, the panels will more than pay for themselves. The savings over the 20 years will exceed the initial costs by $24,000 assuming current electricity rates; the savings will be higher if electricity costs continue to rise. Anyone can view the electricity production of the panels on the website at southbury-ct.org/solarpanels-library, according to a press release from the town.
The Energy Task Force is working on expanding use of solar photovoltaic panels in town. Those interested in this topic are welcome to attend the meetings of the Task Force on the 4th Wednesday of the month at 7 pm.
