According to the Bureau of Meteorology, Brisbane will get about 5.2 hours of ‘peak sun’ per sq. meter on common per day. How a lot usable solar energy does 5.2 peak solar hours translate into? The reply is determined by a couple of issues, together with the dimensions (or kilowatt capability) of your solar system.

The desk beneath offers an summary of how a lot energy you possibly can anticipate some widespread residential solar system sizes to generate, assuming that they’re north-facing and about 75% environment friendly.

Solar panel output in Brisbane (Residential Sizes)

Solar system dimension (kilowatts) Number of Solar Panels Avg day by day system output (kilowatt-hours) Annual Output (kilowatt-hours) 
2kW 5 to 7 7.8 kWh 2,847 kWh
3kW 8 to 10 11.7 kWh 4,271 kWh
4kW 11 to 13 15.6 kWh 5,694 kWh
5kW 14 to 16 19.5 kWh 7,117 kWh

How to seek out the optimum solar system dimension to your home

When you take a look at your electrical energy invoice, you must be capable of see your energy utilization listed in kilowatt-hours (kWh) – the usual models utilized in electrical energy billing. Your kWh consumption will range by season and month. You ought to be capable of work out roughly what number of kWh you utilize per day on common by taking a look at your previous electrical energy payments. As a rule of thumb, the typical Australian home makes use of between 15 and 25kWh of energy per day.

Knowing this quantity will provide help to select the appropriate solar system dimension, however as a result of solar is so inexpensive nowadays, sizing your system will not be an actual science. In reality, the most typical solar system dimension in Australia is 6.6kW due to the good worth for cash that they provide (i.e. a cheaper price per kilowatt). If you utilize considerably greater than 25kWh of energy per day, a solar system bigger than 6.6kW might be value investigating as properly.

As the speed you purchase power for in Australia is all the time increased than the speed you possibly can promote solar power for –  the extra of the solar energy you ‘self-consume‘ (i.e. use directly) the better your financial return will be.

Young Adults / Older Family 5kW of Solar Panels and a 3.5 kWh battery $774 12.8 years > 20 years
Retirees / Young households 6.6kW of Solar Panels and a 6.5 kWh battery $1,465 9.1 years 18.9 years
Big Energy User 13 kW of Solar Panels and a 13.5 kWh battery $2,548 9.7 years > 20 years

You can assessment all of the methodologies and assumptions within the full article.

Despite the lengthy payback interval we’re nonetheless seeing many owners putting in battery techniques. There are non-financial causes which might be turning into growing vital together with holding the lights on throughout a blackout and lowering carbon footprints.

Many others are putting in ‘battery ready’ techniques which embrace a hybrid solar inverter permitting them to select from a better collection of batteries as soon as they turn out to be extra inexpensive – or if a authorities rebates scheme is available in to play.
