Scalability (changing the size of your solar system) is an important consideration in a solar installation. After all, the system that works for you now may not cut it in 5 years time. Noosa Electric Co provides an Advanced On-Grid AC Solar Solution which brings new capabilities to residential and commercial solar. On this page, we examine how AC Solar creates a more scalable solution than DC Solar, ensuring your installation can adapt to suit your changing needs in the future.
Do You Know About AC Solar?
AC Solar is an advanced solar solution for Australian Homes and businesses. It holds advantages in safety, efficiency, scalability and longevity. Noosa Electric Co installs AC Solar solutions in Noosa and surrounding suburbs.

The Need For Solar Scalability
We live in an era of change and adaptation. While it isn’t always easy to see what the future will bring, it can be certain that it will bring more change! For example, in 5 years time you may have an electric car, (or two) in the garage that need to be charged every day. That’s why factoring scalability into your installation is important.
How Is Solar Scaled Up?
To increase the power generated by your solar system, either more panels need to be added or existing panels need to be replaced with more efficient panels. Either way, the goal is to increase the solar energy being converted to electricity.
The Problem with Scaling DC Solar
In a DC installation, the conversion from DC to AC is done at a single, central inverter. Adding more panels to your system will increase the DC voltage going to your inverter. A disadvantage of this approach is that the capacity of the system is limited to the capacity of the inverter: a new inverter may be required to handle the addition of more panels to your system.
Scaling With AC Solar
AC solar works differently. The inversion process is accomplished at each individual panel, meaning that panels can be added to the system as required without jeopardising the ability of the system to handle the added power – the system does not rely on the capacity of a a centralised inverter. Another advantage of AC Solar is the minimum panel requirement. DC systems require a minimum of 8 panels, whereas AC systems don’t have a minimum. The configuration can be scaled to suit your needs, however big or small they may be.
