Projects: Eureka Elementary School in Granby

Matrix Energy designed, supplied and commissioned the system, comprising twenty four SolarWorld 245 Wp monocrystaline PV modules, 30 kWh AGM battery bank, two Outback FlexMax80 MPPT charge controllers and a Xantrex 4.5 kW / 48 VDC inverter/charger pre-assembled on an E-panel.  The PV array was installed on custom mounting hardware with ballast on the school’s flat roof.  Electricity generated by the PV array charges a battery bank, which in turn powers some the building’s loads via the inverter.  If the battery bank becomes discharged during lower solar insolation months, the electric utility serves to re-charge the batteries through the inverter’s integrated charger.  The system can be expected to generate approximately 6,800 kWh per year of clean, emissions-free electricity.
