Thanks to funding from the Friends of the Mercer Public Library, a new 6.12kW solar energy system went online at the Mercer Public Library in October, 2017. As of May 21, 2018, the system has generated 3.35 MWh of power! 

Check out our solar monitoring panel to see how much energy we're generating right now, or look at our statistics by the day, month, or year. 

You can also view the data from our weather station to find out how our local weather affects the amount of power we generate from our photovoltaic system.
