In 2024 there’s definitely no shortage of ways we can produce clean, renewable energy at home – so what are you waiting for? Learn all about the 10kw solar system output, the cost to install a 10kw solar system, and if this sized solar system is right for you.

Key facts

Is a 10kW solar system right for you?

Solar is the future, and advances in technology mean that our imagination only limits us. With 10kW systems becoming standard for large family homes, it’s not too hard to imagine a world where electricity consumption doesn’t matter at all! The average Australian household consumes around 20 kWh per day, with a 10kW solar system producing up to 40 kW per day. If you feed your excess power into the grid, you can pay off your system with the feed-in tariffs.

A 10kW solar energy system is ideal for those with high daytime consumption, and it’s also a good fit in small business settings with low commercial usage (40 kWh per day). Offsetting this expense by selling electricity back into the market on nights & weekends means you never need maintenance from utility companies again. The best way to discover what size solar system you need would be to calculate your daily average power consumption.

Advantages of a 10kw solar power system

The large solar systems that we can expect in the future result from homeowners having an opportunity for further renewable energy capacity. While a 10kw solar system is more expensive than its smaller counterparts, there are many benefits to having one his size. Below are a few advantages of having a 10kw solar power system:

What can I run on a 10kW system?

You can run an abundance of household appliances on a 10kW solar power system. From the small items, such as a heater and toaster, to the larger things, like the geyser and television. A house powered on a 10kw power system can run everything that relies on electricity. The average household in Australia uses up to 20kw per day, while the 10kw power system produces up to 40kw power per day.

Battery storage with a 10kW solar system

For a 10kW solar system with battery storage, you can expect to pay between $20k – $26K for full installation. While your panels on the roof are guaranteed 25 years of use in most cases and have an expected lifespan that extends up into the 30s if not higher – bear in mind this doesn’t account for when batteries go bad before their time! Adding one will be financially beneficial only if using at least half daytime electricity every single day, meaning those who need more than around 20-30 kWh per daylight shining through may want to consider investing today as well instead.

How many batteries should I invest in?

A solar battery storage system allows you to store the solar energy that you generate during daylight hours for use at night. Solar panel systems generate most of their electricity during the daytime when there’s not as much demand for utilities. The excess power can be stored in a battery instead. Not only does your home or business have free backup-power capabilities with no additional costs involved, but many people buy them because they provide an extra layer against blackouts. Only one battery is needed, but the importance lies in the size of the battery. Always ask a professional when it comes to choosing a battery size.

How much energy can a 10kW solar system generate?

Generally speaking, while it depends on where you live and how much sunlight your house receives, a 10kw solar power system can generate up to and sometimes even over 40kw a day. The average Australian household uses around 20kw per day. If you have a large house and are using appliances and heavy energy reliant appliances, a 10kw solar system will work for you.

Savings and payback for 10kW solar systems

The payback period for a 10kW system varies according to your location, electricity usage habits, and suitable properties. If you use more than 30kW a day, it is possible to have this paid off within five years of owning it if purchased with good quality solar panels, which may save homeowners up to $100K throughout their 25-year life span.

Frequently Asked Questions and Answers

A 10 kW solar power system will produce about 40-kilowatt hours of electricity each day. That means you’ll need a battery with the storage capacity to match, which amounts to at least 28 kWh for 30kW systems or 84 kWh if there are 120+ Kilowatts available per day. On average, you’ll need a large battery that can serve to maintain over 28kw of power per hour.

Yes, a 10kw solar power system can power a small to the average-sized house. Generally speaking, the average Australian house uses up to 20kw of power per day. A 10kw solar power system sequestered up to 40kw per day. That means there is more than enough power to fuel an entire house. In fact, a 10kw system is ideal for those wanting to live off the grid.

Solar is a popular and affordable way to generate electricity. A battery is sometimes recommended to help store and generate more power, even during low light hours. A 10kW solar system with battery storage can cost between $20,000 -$26,000 for full installation, which will save you on average more than twenty-five per cent off the power bill each year!

A 10kw solar system is large to accommodate a system that produces up to 40kw of power per day. A 10kW solar system consists of 27 solar panels. This is under the assumption that you use 370W panels – which will give you 9.99kW each. Separately, all panels will be about 1.8m x 1m, so you’ll need at least 48.6m2 of roof space.
