Second Photo: The rest of the PV - two additional KW photovoltaic modules were then added to complete the system (the wind machine is being repaired and not in this photo)

For the current full system: 3KW Evergreen #115 (27 modules) and a 1 KW H40 24V Whisper Wind go to a grid tie Trace 4024 bimodal inverter for a line-tie system. There are 4 T105 US Battery 6V batteries which ballast the wind system, which is 24VDC. The Controllers for the PV are Outback MX60. There is a KWH meter keeping track of the entire production, with a PV monitor in the charge controller to isolate the PV production, with the difference between the two being the wind system. The students at the Putney School participated in the training and installation of these renewable energy systems.
