20kw Solar Systems


Do you have a 3-phase power connection? If so, keep reading as this maybe just for you! For a single phase connection, you can go up to a 13.3kW system.

If you live in a sunny area, installing a solar power system might be one of the best ways to save money on your energy bills. A 20kW solar system will potentially generate enough solar to power your business, pay for the system cost, and be a profitable investment in a few years. With households & businesses facing increasing pressure from rising grid electricity prices, clean and affordable energy is within reach.

How much a 20kw solar system cost in Australia?

A Fully installed 20kW solar system starts from around (as at July 2024) $8,000 in Queensland (after STC discount). With a return on investment currently possible in less than 5 years, a 20kW solar kit is an attractive investment option for your business, reducing short to medium term operating costs and improving your business' environmental profile. With a 20kw system you can potentially save up to $7,600 per year in energy bills, it does depend on how much electricity and solar energy you pay though. For best economy, its best to try and use the power during the day when it is generated.

In terms of actual savings from installing a 20kW solar system on the roof, this depends entirely on the efficiency of the solar energy equipment being employed, and also the type of feed-in tariff agreement you have with your electricity retailer (export of excess solar energy not used and sold to the grid). We'll do a quote to give you an idea of what a system this size will cost, but there are a few things we need to know first, like kind of roof do you have, as well as whether or not the house was two stories. Is your house on a single phase, or is it actually on three-phase connection? Is the connection compliant? Do you want to pay cash, or purchase on terms...

How many kWh’s does a 20kw solar system produce?

Typically, a 20-kW solar power system in Brisbane, will produce about 81 kWh per day on average over the course of a year. A variety of factors can affect the production of a solar energy system, such as the location of the building, the shade of trees and buildings around the building, weather conditions, the orientation of the panels, etc. For a specific estimate calculated on your situation, why not give our ONLINE SOLAR QUOTE a try?. Its possible though that we may need more information, to give an accurate appraisal, but it’s generally not difficult to obtain.

20kW Solar System Output in Major Australian Cities

The implementation of a 20kW solar energy system in major cities across Australia offers immense benefits in terms of sustainability, reduction in energy costs, and a positive impact on the environment. In cities like Sydney, Melbourne, Brisbane, Adelaide, Hobart, and Perth, the 20kW system output varies due to factors such as geographic location, system orientation, and weather conditions.

Average Daily Solar Energy Production

In Sydney, a 20kW solar system produces an average of 72kWh of energy per day, while in Melbourne, the output is slightly lower at 69kWh. Brisbane, with its sunnier climate, sees an average daily output of 81kWh from a 20kW system. Adelaide's solar energy production averages 78kWh per day, and in the southern city of Hobart, the output is around 66kWh. Perth, on the west coast, boasts the highest average daily output among these cities at 85kWh.

Implications for Urban Energy Demand and Sustainability

This substantial energy output can help meet the growing electricity demands in these urban areas while reducing the dependence on fossil fuels. Furthermore, the Australian government's commitment to renewable energy, along with various incentives and rebates, make the installation of solar energy systems increasingly attractive to both residential and commercial consumers, fostering the growth of a greener and more sustainable future for the country.

20kw solar with a battery storage

Even though we don’t recommend any battery systems at this time, that is likely to change in the near future. All solar systems we supply can have battery storage systems installed, using AC coupling. This allows you to connect a battery to any property, as it connects directly to the main power supply. If you were looking to add a battery storage option to a 20kW solar system package you will be able to use the power produced during the day, for use at night. Saying that, battery backup options are quite expensive, and tend to greatly increase the repayment period of your investment. Talk to us and we will be happy to advise you if this is the right option for you.

In conclusion

A 20 kW solar system is undeniably a relatively large power plant, and notably, it is the largest size that most residential situations can accommodate. Nevertheless, it is an optimal solution for commercial premises, especially if you possess ample roof space and maintain consistently high daily energy consumption. Subsequently, the savings you can reap from a 20 kW solar power system hinge on the power it can generate for your business and your specific power requirements. Consequently, the amount your business can economize by installing a 20 kW solar PV system will largely rely on the electricity rates you pay and your overall electricity usage. Rest assured, we are here to support you in determining these factors.
