Based on a feasibility study and conceptual design conducted by Cascadia Renewables, the required system will include a minimum 16.4 kW DC solar photovoltaic (PV) array and 15 kW/40 kWh battery energy storage system (BESS). The PV system will be installed on the building’s exposed fastener metal roof. The building roof will be undergoing structural upgrades prior to the PV system installation, as detailed in the feasibility study. The BESS is designed to provide up to 12 hours of autonomy in the winter and 16.5 hours in the summer without relying on the existing standby generator. The solar plus storage system must be capable of parallel operation with the existing standby generator to allow for cycle charging of the BESS when needed, ensuring continuous building operation during longer duration grid outages The system will include a minimum of 16.4 kW DC solar photovoltaic (PV) capacity and a minimum 15 kW/40 kWh BESS. The PV array will be roof-mounted on the exposed fastener metal roof, and the BESS is intended to be wall-mounted on the north exterior of the building.
