At Hot Solar Power we use BYD panels. This is a Poly Crystalline or Multi
Crystalline Panel that is sliced from long cylinders of silicon and you can
clearly see the crystals which are about 10cm diameter. These panels are
accredited with the Clean Energy Council of Australia and conform to Australian
To allow for optimum output it is ideal to have a North facing roof to mount
the solar modules although 45 degrees off North is acceptable.
It is not recommended to install a solar module facing south as this will
significantly reduce the performance of the system.
