| The hybrid Wind/Photovoltaic (PV) system was designed for the Lowell National Historic Park maintenance shop. This grid-connected system consists of PV panels, wind turbines, inverter, battery storage, and other components such as fuses, dc/ac disconnects and transformer. Sizing the PV and wind turbines to fit on the roof was determined. The battery storage and inverter were chosen to install in the maintenance shop building. The expected energy production was compared with data file from University of Massachusetts Lowell site. The four proposed PV systems and wind systems were analyzed to determine and compare their energy production, cost, and pay back period. The 20 KW PV system and 2.5 KW wind system were chosen to be the most effective and demonstrating renewable technologies and reducing the electrical load of the maintenance shop. |
