We know choosing the right solar system can be confusing and overwhelming, so we’ve simplified the process for you by breaking down the key elements of a solar panel system and creating a checklist of the things you should consider before making your decision.
CHECK OUT YOUR ENERGY USAGE BY CHECKING THE RIGHT-HAND SIDE OF YOUR ELECTRICITY BILL.
It’s important to take note of when you use the most energy. If you are working from home and using many of your household appliances during the day, your usage and will be different to someone working from an office and away from home for long periods of the day. This should be considered when deciding what type of system you should choose.
BELIEVE IT OR NOT, IF YOUR PROPERTY HAS SHADE FROM TREES, BUILDINGS OR OTHER STRUCTURES.
It can affect what type of solar panel system will provide the maximum output for you. Take a look around your property a couple of times a day to check if your roof is shaded at any time.
A COMMON MYTH IS THAT SOLAR PANELS CAN ONLY BE INSTALLED ON ROOFTOPS FACING NORTH.
A common myth is that solar panels can only be installed on rooftops facing north. Whilst it’s true that north-facing solar panels generate the most energy overall, technology has advanced to allow east-facing and west facing (or a combination of both) a viable solution in providing maximum efficiency and return on investment.
As a general rule, east-facing panels will produce the most energy in the morning, north-facing solar panels will produce the most energy in the middle of the day, and west-facing solar panels will produce the most energy late in the afternoon.
DECIDING WHAT SIZED SOLAR SYSTEM YOU NEED IS DEPENDENT ON THREE MAIN THINGS:
Deciding what sized solar system you need is dependent on three main things:
1. The budget you’d like to allocate to your solar system
2. The amount of roof space you have available for panels
3. The desired outcome you’d like to achieve
In our experience, most households will need a minimum 6.6kW solar panel system complimented by a 5kW inverter. Regardless of having single or three-phase power to your home, it is important to find a system size best suits your needs. It is a common myth that a home with single phase power should have a 6.6kW system installed. The system should be and can be designed to suit the household needs regardless of what power supply it has.
We suggest speaking with a qualified Clean Energy Council accredited designer for personalised advice on the number of solar panels and system size for your property.
ONCE YOU’VE CONSIDERED THE ABOVE STEPS, IT’S TIME TO START SHOPPING.
Once you’ve considered the above steps, it’s time to start shopping.
It’s important to choose a solar installer that is Clean Energy Council accredited in order to be eligible for small-scale technology certificates (known as STCs).
The Clean Energy Council (CEC) is Australia's peak body representing the clean energy sector, it certifies both installers and systems that meet their minimum standards.
You should look for an installer that has been in business for several years; that specialises in solar and has excellent customer reviews.
