What are the key elements of a solar power system?

At its most basic, a solar power system consists of photovoltaic panels, an inverter and the wiring to connect them to each other and to the mains power. The PV panels generate DC electricity from sunlight and the inverter converts the DC power into usable AC power).

What do the various numbers attached to solar systems mean?

6.6kW, 10.7kW and so on... These simply refer to the size of the system. The higher the number, the more solar panels there are. More solar panels mean more ability to generate electricity.

What electrical upgrades are typically required to install solar?

This entirely depends upon how old your existing electrical system is, but common upgrades that are carried out alongside installing solar include updating meters (usually done by your electricity supplier), upgrading switchboards and replacing aged wiring.

What’s the difference between single phase and three phase power?

Single-phase power is a two-wire alternating current (AC) power circuit with one power wire and one neutral wire. Three-phase power is a three-wire AC power circuit.

A three-phase power supply delivers power at a more consistent rate as there are fewer peaks and dips in voltage, than with a single-phase power supply. Residential homes are usually served by a single-phase power supply, while commercial and industrial facilities usually use a three-phase supply.

Is it worth investing in a battery for my home or business?

Whether a battery is a worthwhile investment entirely depends upon your energy goals, power consumption and personal circumstances. A battery is a great way to ensure you make the most of all the energy you generate through your solar panels and provides energy security in the event of a blackout. However, if these aren’t essential to you, the cost of the battery may outweigh the benefits of solar. Contact us to book a chat to discuss whether a solar battery is right for you.

What solar incentives and rebates are available nationally?

The key federal government incentive in Australia is Small-scale Technology Certificates (STCs). These are issued by the Australian federal government to small businesses and households installing renewable energy systems. The number of certificates you’ll get will depend on your solar system capacity, installation date and your system’s location.

What kind of warranties do I get on my solar panels, inverter and/or battery?

Generally, manufacturer warranties extend to up to 25 years on solar panels, up to 10 years for inverters and up to 10 years for batteries.
