How do Solar Panels Work?

PV panels are generally fitted on the roof facing a northerly, westerly or westerly direction, and tilted at a particular angle to maximise the amount of sunlight that each panel receives.

A solar system is made up of multiple solar photovoltaric (PV) panels, a DC to AC power converter (inverter solution) and a framing system to hold the PV panels in place.

Suburban homes in Australian and New Zealand are connected to the electricity grid via power lines. Our electricity system users 240V alternative current (AC), but the electricity generated by solar panels consists of variable direct current (DC). To transform the DC electricity into AC electricity for ordinary household use, grid-connected solar PV systems have inverters attached to each PV panel called micro inverters or a single inverter, or a string of connected PV panels called a central string inverter.

The third possible inverter solution is power optimisers, which are a variance of the string inverter and the micro inverter. All these technical solutions can create a great solar system.

Ask us for advice on which of these inverter solutions offer the most suitable solution for you.

Quality inverter/micro inverter solutions include Fronius, SMA, Solaredge and Enphase brands.

Today houses with grid-connected solar systems consume solar-generated electricity first, before switching to the electricity grid if more electricity is required than the solar system is able to generate.

Grid-connected solar systems can also feed electricity back to the grid if too much electricity is generated via the solar system for the immediate needs of your home. Unless you add storage batteries to your system, a grid-connected solar system is unable to store power in your home for use at night.
