How do work?
For a standard solar package, photovoltaic (PV) panels are mounted to the roof and connected to inverters on your wall at home, easy as that.
The inverter is connected to the house’s switchboard, providing energy from the solar panels to meet your home’s energy needs. When sunlight shines onto the solar panels; electrons inside the panels are knocked free from atoms and generate electricity.
These loose electrons are then captured and move along a circuit, forming direct current (DC) electricity. The DC electricity moves from the solar panels to the inverters on your wall, where DC electricity is converted into alternating current (AC), ready to be used in your home.

Going Solar, it would be best to use the minimal amount of energy as possible, to optimise your energy savings and save more.
The number of solar panels you should use, would depend on your current energy usage and energy goals. There are two keys aspects to consider when thinking of what size of system is suitable for your home:
Your electricity usage varies depends on your habits and how many people are in your household.
These numbers are only estimates, it largely depends on how many appliances you use and how often; not the size of your house. Best to look at your power bills to know your average energy use in kilowatt-hours (kWh), and it changes over the months and seasons.
- A regional home with two adults and two kids, might use between 30 to 50 kWh a day depending on how many appliances you use.
- An adult couple with no kids might use between 15 kWh to 30 kWh a day.
- A single adult in an apartment might use a minimum of 10kWh a day.
Using your electricity during the day or night may influence the size of the solar system you need. The time of day you use energy also influences the best location to install your solar panels onto your roof. You might want to add a battery to your system; if you produce more energy than you use, you can store the energy with the battery, and even sell energy back to the grid or even just use it at a later date.
