The best position to install PV panels is on a roof plane, which is facing closest to true north. Facing closest to true north optimises the exposure of the solar panels to the path of the Australian sun, resulting in maximum power generation.
The tilt angle of the panels is also important and is dependent on the pitch (angle) of the roof. Most Australian homes have a moderate roof pitch (angle) and this is usually suitable to the panel tilt angle required. However, if you have a flat roof, or an unusual roof pitch, b.solar can supply tilt frames that allow the panels to be adjusted to the optimum angle.
The inverter is best installed near your existing meter box, either inside or outside. Most inverters are IP65/67 rated which can withstand Australia’s harsh weather climates.
