This guide has been prepared to assist with the building permit requirements for the installation of solar panels as part of a photovoltaic (PV) or solar hot water (SHW) system on a new or existing building.
Solar panel installations impose additional loads on the roof framing that may exceed the roof structures original design. To ensure a building is structurally acceptable for the installation of solar panels, a registered professional qualified in structural engineering will be required to evaluate the buildings structural capacity and attachment of the panels to the structure.
