Frequently asked questions

What size system do I need to cover my energy bill?
This is one of the most common questions our clients ask us, one with many variables for us to consider – the direction and slant of the roof we can mount the panels on, your average daily consumption, do you incur a lot of shade over the panel installation area, do you have a pool or air conditioner, how many people live in the household and so on. As such, it is difficult to give a generalised answer, and why we prefer to visit your home and tailor to your needs rather than give a more generalised quote over the phone.

How much will I save by installing solar (& a battery)?

If any solar company tells you “You’ll never pay for power again!” you’d think it was fantastic – however, unfortunately that is not the case. Solar will cover your day time use, combined with batteries will allow you to store and use the power you have generated into the evening. In most cases you will receive a bill, our aim is to reduce that bill as much as possible.

With a well sized system, you can expect an approximate saving of 50% off your bill – this may vary and is very dependant on how well you utilise your system and make the most of your solar generation. Our team can help with tips and tricks to reap the maximum benefits. Adding a battery can further your savings by an additional 25% though once again this is dependant on your usage. One of the services we provide when we deliver your quote, is to calculate the projected savings you will incur on your power bill, including a projected time frame in which your solar system will have paid for itself via the savings you make on power.

How many panels will go on my roof and where do they go?

The amount of panels required will depend on the required kilowatt generation of your home – if you install a 5.2Kw system, around 16 panels will be required to generate that power. The placement of our panels is designed to maximise the sun exposure during the day – usually favouring a north or north-west aspect to utilise the sun’s rays well into the afternoon, though an east/west split array can also function quite well. All of this is dependant on the roof space available at your home, the direction your house is facing and if your roof is shadowed by trees, rooftop apendages (ie antennas, pipes, etc) as this will also impact your system’s ability to generate power.

What is the difference between AC and DC Systems?
Your home uses AC (Alternating Current) Electricity, while solar panels produce DC (direct current) Electricity. This is why a solar array requires an inverter to convert the power from DC to AC. The advantages of an AC system (micro inverters converting the electricity on the back of each panel) are that you have fewer losses from shading, soiling, or overcast days. Micro inverters deal with smaller loads of electricity, making them safer and more efficient, and don’t have large current passing through an inverter mounted to the wall of your home. Enphase micro inverters are dust-proof, engineered and tested for over a million hours to ensure the safest, most efficient and reliable inverter in the world.
Will my system be battery ready?
All systems now sold by Planet Power are battery ready.
Why do we use LG and Jinko panels?
Planet Power have a commitment to only supplying and installing the best quality for our clients. This is why we not only Premium installers for Enphase, Accredited installers of Tesla Powerwall 2, but only sell LG and Jinko panels. LG are market leaders in quality and efficiency, their monocrystalline panels come with a 25 year product and performance warranty. Jinko are the largest manufacturer of solar panels globally, we use Jinko’s highest-rated panel, that is on par or second to LG on tests performed by CSIRO and other industry bodies. Paired with Enphase micro inverters, each of these panels is a component to the most reliable and efficient system available, with warranties that protect you for ten years and beyond.
How long does it take to install my system?

Once you pay your deposit we average 3-4 weeks to install your system.

This time frame allows us to order your stock, get the relevant approvals from the various State authorities, and schedule you in with install teams to do the actual installation. Installation generally takes one day or less to install.
