How Much is a 5kW Solar System in 2024? (with an important warning)

Tesla Powerwall Blackout Protection

Trying to work out how much to pay for a 5kW solar system isn’t easy.

Many of our customers tell us how steep the learning curve is when trying to choose a system. The good news is it has never been easier to choose a good quality system thanks to record-low prices on the better brands.

Price of a 5kW Solar System

To help you cut through the confusion, we believe you should have all the information you need to make an informed decision, including pricing.

And so here it is:

For a good quality 5kW solar system, the average solar price in Sydney starts at $5,000, fully installed.

If you want a smart solar system with panel-level optimisation, expect to pay around $6,000 for a SolarEdge system. A top-of-the-range system with Enphase Microinverters and high-efficiency solar panels from REC Solar will cost around $10,000, and so this is about the most you can expect to pay if you want the best of the best.

This 13-panel system will output around 20kWh a day, and can save you up to $500 every quarterly power bill.

Price Of A 5kW Solar System With Battery Storage

A 5kW solar system is often considered the smallest solar system that is compatible with a Tesla Powerwall battery. Any smaller, and you generally won’t generate enough solar power to charge the 13.5kWh battery in the winter half of the year.

A 5kW solar system with Tesla Powerwall battery storage starts at $21,500, fully installed. This includes a good quality solar system using Q Cells panels and a string inverter. A top-of-the-range 5kW Smart Solar System from Enphase with battery storage starts at around $26,000, fully installed.

Power Bill Reduction

*Credit eligibility criteria, terms & conditions, fees & charges apply. The 5.54% variable interest rate is current as of 15/01/2024 and subject to change without notice. The comparison rate of 6.52% is based on an unsecured loan amount of $30,000 over a loan term of 5 years.

Working Out The Right Price To Pay For A 5kW Solar System

Trying to work out how much to pay for a 5kW solar system isn’t easy – many of our customers tell us how steep the learning curve is when trying to choose a system.

Unfortunately, a lot of solar systems you see advertised online are far too cheap – they use no-name panels, and we hear stories every week of people being left high and dry by installers who go belly-up, or simply won’t return phone calls.

‘Cheap solar’ has become a real problem in Australia, and this race to the bottom has been the death of many installers, who simply couldn’t afford to service all the warranty claims. This is made even worse by the fact that so many manufacturers have either disappeared or pulled out of the Australian market:

Enphase Components

That’s why we say a 25-year warranty isn’t worth the paper it’s written on if the company backing it isn’t going to be around. It is estimated around 1 in 3 solar systems in Australia are now unsupported, and this is only set to continue due to the nature of Chinese manufacturing and larger economic factors, but it’s bad enough already.

Cheap 5kW Solar Systems – What To Look Out For

The first thing most people do when they search for a 5kW solar system is to find out how much it costs. Here are some typical ads you will see in your search results:

Tesla Powerwall Mounted on the Wall

If you are new to solar power, your very first online search could have you believing a good quality 5kW solar system costs around $4000, maybe even less. The ads use words like ‘premium’ and ‘tier 1’.

It all sounds great… except it’s not. $4000 is far too cheap for a good quality 5kW solar system.

You Have Been Warned – Don’t Buy A Cheap 5kW Solar System

If you were to get 3 quotes for a 5kW solar system from reputable solar installers in Sydney, you would find that we would be offering similar brands, and that our prices are all within a few hundred dollars of each other. Yes, there can be slight differences, but for the most part, the quotes will be around the same price.

To put it another way, you won’t find a $6,000 5kW system ‘on sale’ for $4000. Even if you’re happy for the installer to cut a few corners (which you shouldn’t be), you simply can’t get top quality brands for that type of money.

Good quality solar panels have dropped in price to the point that it no longer makes sense to consider the bottom end of the solar market when buying a 5kW solar system. You can have the best solar panels from the world’s leading manufacturers, online monitoring, a professional installation, full technical support, and still get a return on your money in 3-5 years.
