At Platinum, we’re all about helping Australians switch to solar, the easiest way possible


How do I know what size solar system I need?

It depends on how much electricity you use, when you mostly use it, where in Australia you live and how much you’re willing to invest. The best way to make sure you get the right system is to have an expert calculate it for you. Just contact us and we’ll organise a free tailored consultation at your premises to work out your individual needs.

How much does a solar system generally cost?

A fully installed solar system in Australia (including the STC discount) will currently cost somewhere between $4,000 and $6,000 for a 3kW system, between $5,000 and $9,000 for a 5kW system and between $12,000 and $16,000 for a 10kW system.

Obviously, no two homes have the same energy requirements, so for a completely free and tailored consultation on a solar system (and batteries), speak to us.

What is my solar system likely to produce on average?

It will depend on where you live in Australia, with cooler climates such as Hobart producing an average of 3.5 kWh per day per kW installed and warmer climates such as Alice Springs producing roughly 5.0 kWh per day per kW installed.

Where are the majority of solar panels made?

Most are manufactured in China, but this is not an indication of poor quality, as there are some excellent brands of Chinese-made solar panels. Those not made in China generally come from places such as Taiwan, South Korea, Singapore and some are even made here in Australia.

We only use the highest quality hardware in all our installations. that complies with strict certifications and comes from leading brands such as LG Electronics, Sunpower, REC, Fronius, SMA and SolarEdge. Speak to us today for a free consultation on what the best solution is for you and your budget.

Will solar panels stand up to hail?

Good quality panels made from tempered glass usually will, but even the best panels won’t resist unusually large hail, so it’s best to inform your home insurer when you purchase solar and have it covered under your policy.

Will my solar panels still work when it’s overcast?

Yes, but they will only produce somewhere between 10% and 40% of their rated capacity. However, individual overcast days aren’t important, providing you get enough sunlight over the course of a year to justify switching to solar.

Can I claim the rebate if I add another solar system?

Yes. Solar upgrades are also eligible for the government rebate.

What are the standard warranties for solar panels?

The industry standard for solar panel performance warranties in Australia is 25 years. This guarantees that a solar panel will only degrade in performance by a small percentage every year.

More importantly, a solar panel’s product warranty is a manufacturer’s warranty covering any defective materials or workmanship and in Australia this is usually for a period of between 10 and 12 years. High quality brands, such as LG, offer 25 year comprehensive- parts, labour, transport product and performance warranties.

What is a Tier 1 solar panel?

A tier 1 manufacturer simply means they make high volumes of panels, it doesn’t necessarily mean they are a good quality company that manufactures good quality products. It’s vital to look for high quality panels with comprehensive warranties from long term, financially stable companies available to support you long-term if things go wrong with your system.

Is Tier 1 better than Tier 2 or Tier 3?

Not necessarily. Because the rating includes criteria such as manufacturing and deployment scale, only large manufacturers will score well enough to be rated Tier 1, while small makers may produce equally good panels, but only in small quantities. Choosing Tier 1 panels simply ensures you are buying a popular brand with good quality control, after sales support and warranties.

How long do solar panels normally last?

The average life expectancy of good quality solar panels is around 20 to 25 years and can last longer if well made and maintained. However budget style solar panels have a life span of only 10 to 12 years. This is why Platinum Solar only provides high quality solar panels.

Should I buy a used solar system?

Not a good idea for the following reasons:

  • You won’t get the government STC rebate, which is now almost enough to pay for new solar panels.
  • You don’t know what sort of condition it’s in and it may be damaged.
  • A used system doesn’t come with a warranty.
  • Unless it’s relatively new, it probably won’t meet current Australian standards, so it will be illegal to install.
  • If it’s an old or uncommon type, you may have trouble finding anyone who can install it.


If I decide to add batteries to my solar system, do I need to change my existing inverter?

No. An installer can add a battery that’s AC-coupled to your solar system and has a separate inverter, allowing you to retain your existing inverter.

What type of inverter should I buy if I want to add batteries later on?

It doesn’t matter because, as explained above, you can add a battery without having to change your inverter.

What does a ‘cycle’ mean in relation to lithium-ion or similar batteries?

In general terms, a battery can be said to have completed a cycle when it is fully discharged. In the case of lithium-ion batteries, a cycle can be a number of small discharges adding up to one full discharge, as these batteries do not experience any additional deterioration from small amounts of power being used throughout the day.

Is it possible to add batteries to a micro inverter-based solar system?

Yes, by using a technique known as ‘AC coupling’ where an installer wires them directly into the 240V AC in the switchboard using an AC battery inverter.

What qualifications do you need to design and install a battery storage system?

You must have either grid-connect installation accreditation with battery endorsement or grid-connect installation accreditation along with stand-alone installation accreditation. Platinum Solar is accredited to all government and industry standards.


I am thinking about solar but wonder if it’s too late. Is it still worth it to get a solar system?

Yes. The good old days of big returns from feed-in tariffs might be gone, but solar can still dramatically reduce your energy bills. The federal government’s rebate scheme (STC) won’t be phased out for a long time and that means you can still get a big discount on the upfront cost too.

Take a look at some information about government rebates here and if you still have questions, feel free to contact us for a free consultation.

I consume most of my electricity when I get home at night - should I get solar?

Definitely. When feed-in tariffs were at their lowest, having solar when you weren’t home during the day probably wasn’t a great investment. But, with energy prices now on the rise and healthier feed-in tariffs being paid, it’s becoming a worthwhile proposition once again. Add a battery system to store energy generated in the daytime for nighttime use and maximise your return from your solar system.

What does kWh mean and what's the difference between that and a kW?

Let’s break it down. k is for kilo (i.e. 1000), W is for Watt (a measure of power) and h is for hour (a measure of time).

Therefore kW stands for kilowatt (1000 Watts) and kWh means kilowatt-hour (a measure of energy rather than power).

As an example, If your solar panels produce 1 kW of power for 60 minutes, they have produced 1 kWh of energy.
