30kW Residential Solar System + Battery | GEM Energy

Today we are discussing the benefits of investing in a larger solar system. We will be looking into the personal home solar system of Aaron Hilton who is one of our Senior Project developers here at GEM Energy. With over 10 years of experience in the solar industry, Aaron has expertise and insights into why a bigger solar system is better!

This east west split array, 30kW system includes:
90 x Canadian Solar HiDM 335W
1 x Fronius GEN 24 Inverter
1 x Fronius SYMO Inverter
1 x BYD HVS 10.2 Battery

Canadian solar is a great manufacturer that we have worked with for weeks, I am really happy with the build quality and support we believe they are a real market leader.

I have opted to go for a Fronius inverter solution They're an excellent manufacturer, the components are always very high quality, products are always reliable and the feedback from our installers is that they're an easy inverter to install.

Fronius has provided us with the new GEN24 hybrid inverter which means that it can have a battery connected to the system. And I have coupled that with a BYD battery.

I'm really happy with the installation quality that GEM has been able to provide. Thats the GEN 24 10kW there on the left and I've also got a Fronius SYMO 15kW as well so the two can work together with the communication process that Fronius has.

The system's east west split means that in the morning when the sun is coming up, the inside of the array is getting full sun and in the afternoon the opposite side gets full sun. What that means is the production is very rarely in an excess of 15kW peak output whereas I've got 30kW of PV on the roof.

I have modelled it deliberately so that with the east west split I've been able to get away with 30kW with very little loss. My home is 3 phase so I can have 10kW of AC rated capacity connected.

The New GEN 24 inverter is really exciting. It is one of the first inverters that has EPS (Emergency Power Supply) so if the grid goes down, I can back up my entire house. I can back up all 3 phases with the GEN 24 coupled with the BYD battery solution. So I can get by for a considerable period if the grid were to go down. It is a real peace of mind for me and my family.

When speaking to people who have had a loss of power for a considerable amount of time, it has been a massive inconvenience. Now with the GEN 24 available it is something we can now insure against while saving money on your powerbill.

All of this I can monitoring from my Solarweb portal so I don't have to come out here and look at screens I can actually just see from my tablet everything how much energy is producing, how much money I have saved. Also with my Tesla car, I can have the car charge at a level that matches my solar production. The Solarweb portal makes it really easy to manage that process.

Technically with this setup, the home is 500% efficient so it is well and truly taking care of our needs and maybe helping a few other houses on the street.

Over the last few years we have seen the average sized solar system go from a 6.6kW to a 9kW system and it is looking lie it is going to continue to rise what would be the reason for this?

We are starting to service clients that are now onto their 3rd solar system. So at first they may have gotten a 1.5kW system, the next system being closer to the traditional 6.6kW system and now they are coming to their 3rd system. People are understanding more and more the fantastic benefits of solar. I am having more and more people asking "whats the biggest sized system I can get?". They understand the feeling that it gives them and the financial return.

The ability of the house to connect a large system is one of the first things we look at. I deliberately paid the extra for my house to be connected to 3 phase. Fortunately there is very good feed-in tariffs available. Even if I was full export and exported everything to the grid and only received a feed-in tariff, the system will still pay for itself in under 5 years.

It is making money in a way that is beneficial for the environment and makes sense here in Queensland. No one has ever said they wish they had got a smaller solar system. If you've got the roof and you've got the capacity then I strongly recommend considering a larger solar system for the revenue potential.
