System Inverters

A crucial component of your Home Solar Energy System is the inverter. Inverters convert the DC electricity produced by the solar panels into AC electricity that your home and the grid utilise. We highly recommend opting for a high quality inverter that has Australian warranty support. Below are some features to compare:

Solar Mounting System

The mounting system physically connects the solar panels to your roof. The mounting system is a crucial component of a solar array as it will be subjected to major environmental stresses.

Cooper and co. Electrical Services only use premium corrosion resistant mounting systems that are guaranteed for 10 years.
