Home solar has received an enormous upgrade, allowing 10 kW solar systems. The maximum residential solar system size allowed has been lifted from 5 kW of inverter capacity per phase, opening the doors for systems with far greater potential. Larger systems tend to save households more money in the short and long term due to feed-in tariffs and solar decreasing in costs. So, homes which are single phase can now take advantage of these costs savings. A key condition of this lift is that there is still an export limit of 5kVA for single phase homes. While this condition may affect some homes, they should simply purchase a smaller system, there are many homes where the limit won’t have an impact on money saved. We will go through what a 10kW solar system could mean for your home.
Due to the 5kW export limit there are two major reasons why you may consider a 10kW solar system. These two reasons being, your home has higher day time energy consumption, or you have low energy consumption and are looking to reduce reliance on the grid. It is recommended that you self-consume at least 30% of energy that your solar system produces. So, if you run your business from home, have electric cars or batteries, or members of your family stay home throughout the day, there is a high chance you could be utilising enough day time energy. In this case, with a 10kW solar system you will have more guilt-free energy to use throughout the day. The rest, up to 5kW, can then be exported to the grid. In the case where you are looking to go off the grid, you can use the excess power to charge batteries for use at night. A key element here is that you keep your energy low so as to reduce your reliance on fossil fuel generators, or the grid.
There are a wide range of factors that will determine exactly how much energy a 10kW solar system can produce. These can include: geographic location, orientation and tilt angle of the solar panels, shade levels over the panels, and the operating temperatures of the panels. In general, REA Solar’s systems will perform better than conventional solar panels in shadier environments, resulting in a higher energy output. The average output of a 10kW solar system in Brisbane, which is north facing, is 39-41 kWh per day. This data is assuming 75% efficiency for a north facing, 30 degree tilted, standard 10kW solar system.
A conventional 10kW solar system would normally make up 27-35 solar panels. This would take up around 80m2 of roof space. However, the space the panels require will depend entirely on the wattage of the panels. REA Solar’s panels are designed to output more energy than conventional panels per m2. This means that they require far less roof space, and less panels to achieve a 10kW solar system. Due to this, the system is ideal for rooftops with limited space.
" I engaged with REA to install my first solar system for our family home over 10 years ago, I was so happy with the system that when I recently moved to a new home I contacted REA again to install a new system. I chose a 10kW system for maximum investment and savings and it has been fantastic again, the advancement in technology from my old system to my new system is amazing and considering most other companies are still selling the same system I installed with REA 10 years ago its testament to REA’s commitment to leading the solar industry. "
Unfortunately, there is no one answer for the price of a 10kW solar system. This is because prices vary based on quality of panels, the location of your home, the type of roof you have, and much more. However, the positive news is that the price of solar is reducing rapidly. The key thing to think about is the quality of the panels. Higher quality panels will last longer, produce more energy over their lifetime, require less maintenance, operate at higher levels and temperatures safely, and ultimately provide a greater return. Rather than looking solely at the initial price of installation, consider the long-term monetary gains. Our team will take you through all of this at our consultation. We will show you the gains you can receive from different sized systems at your property to help you make the best choice.
A key aspect to the returns gained from solar is no longer solar feed in credits, they have become a secondary benefit. The largest benefit to solar is combatting rising energy prices. With a solar system you can take control of your energy bills, keeping them low, while receiving a nice bonus through feed-in tariff schemes. This means you can feel free to use more energy, run the air conditioning when you like, heat the pool, and turn on the heater in winter. The more solar energy you use the more you save. The key thing which makes the return on a 10kW solar system so great is the increased energy available to use and to sell. This means that if you use more energy during the day you will see great returns in the reduction on your energy bill. Adding to this, you will have a higher overhead capacity to sell back to grid, capping out at 5kW. At the end of the day this means that any grid usage is being subsidised at a greater level by the increased power you are selling, while your usage during the day is completely guilt-free.
An existing 5kW solar system can be easily upgraded to a 10kW solar system. Our installers will simply install another inverter alongside your existing one. The key aspect to this setup is that the total inverter capacity should not exceed 10kW, it doesn’t matter the type of inverter you have. It is vital that a smart meter is installed in order to control the export limitation. While with this set-up consumption data may not be reported accurately, our team can assist you in upgrading your inverters if this information is important to you. There are a wide variety of options for upgrading an existing 5kW system to a 10kW solar system. You should give our team a call. They will be able to assist you in finding the right solution for your unique circumstances.
" We installed a 10kW solar power system with REA to power our home and sell power to the grid for credit. The system has operated flawlessly and exceeded the estimated output with panel level performance viewing I can see that my system is always working how it should. We are in the Renewable Energy Industry ourselves trading technology certificates so we have access to many different solar companies however we chose REA as they are industry leading in all solar fields. "
There are many options for installing batteries on single phase if you are installing a 10kW solar system. Certain batteries will unfortunately not be able to be connected. This is because they use a 5kW inverter to convert the AC power received from solar inverters to DC power for storage. While this ultimately won’t have any effect on the grid, Energex still considers this storage inverter as inverter capacity. However, there are other options which can be installed just fine. It is best to reach out to REA Solar. Our team will be able to assist you in finding the right battery storage solution for your 10kW solar system.
A 10kW solar system is now in reach for more homeowners across Brisbane due to export limiting. It is important to consider your personal use case when purchasing a solar system. There are some effects due to export limitation, however, with the right use case, a 10kW solar system could be the perfect option. This system encourages more daytime energy usage making it perfect for those who have a home business, like electric heating, want to run the air conditioning during the day, or have a pool heater. If done correctly, a single phase 10kW solar system could be a very cost-effective solution. If you are looking for a 10kW solar system or are unsure as to which system would be right for you, reach out to REA Solar. We have a free consultation process, in which one of our experienced team members will discuss your options, your solar goals, and any questions you may have. From there we craft you a detailed quote to help you make an informed decision on your investment into solar. Give us a call today.
