Solar Photovoltaic System

Our solar photovoltaic (PV) system consists of eighteen BP 4175T 175 Watt PV modules. DC connection is via two armoured cables to a Sunny Boy 3300 PV inverter in a weather proof enclosure. AC power is fed by armoured cable to a grid connected sub-main inside the house. A Sunny Beam wireless data logger is used to collect power generation data.
