PARTS OF THE SYSTEM

Your solar system will consist of these key components:

Panels

Solar panels are used to absorb the sun’s rays and convert that energy into electricity. They generate ‘direct current’ electricity through the photovoltaic effect.

Inverter

The inverter converts the direct current (DC) electricity created by the solar panel into 240V AC electricity that can then be used in the home.

Long lasting solar systems require a high quality inverter with a robust convection cooling system. Low quality inverters are not suited to the warm Australian climate.

Optimisers (optional)

An optimiser is a device that can be added to one or all panels to help with shading on the roof. An optimiser can increase the panel output by bypassing the shaded solar module which allows the rest of the system to operate to its full potential.

Batteries (optional)

A solar battery stores energy created by the solar PV system. If your system is generating more energy than what you are consuming the excess energy can be stored in a battery bank for later use. Different batteries will have a different lifespan so it is important to take this into consideration when evaluating the return on your investment over the lifetime of the system.

Grid Connect

An on-grid solar system gives you the best of both worlds. You can generate and use your own electricity when the sun is shining, immediately saving you money. But by being connected to the grid you’ll always have uninterrupted power when it’s overcast or night time. The solar system’s inverter, or micro-inverters, can send any excess solar power your system creates back into the grid, further reducing the cost of your electricity.

With Batteries

A hybrid system is a grid connected system which also incorporates a battery to store excess power. Once your battery is full, the grid connection allows excess power to flow back to the grid. The grid also acts as your backup power supply, if the sun isn’t shining and the battery is empty, then power can be sourced from the grid.

Off Grid

An off-grid system, also known as a stand-alone power system (SAPS), operates independently of the grid, storing excess solar power in a battery bank. These systems are best for homes and businesses with limited or unreliable access to the main supply. The excess power stored in the solar batteries is used when the sun is not shining, appealing to clients who want a 100% self-sustaining system.
