Vector Powersmart designed a multi-roof layout to maximise solar production. Our hybrid system design included three Tesla Powerwall energy storage systems (BESS) to store excess electricity for overnight use, so as to maximise savings.
Te Rau Aroha Museum now has a 114 kWp solar photovoltaic (PV) system and a lithium-ion battery energy storage system (BESS). Over 90% of the electricity produced by the solar panels is used within the building. This minimises electricity exported to the grid and maximises the savings to the museum, which ultimately reduces operational costs.
"Waitangi Treaty Grounds is on a pathway to be carbon neutral by 2025. The new solar electricity technology used for Te Rau Aroha Museum is a fantastic step in the right direction."
