While winter and COVID may be putting a dampener on life in general, there was still lots of interest in busting electricity bills with home solar power in July.<\/p>\n

Solar Power System Capacity<\/h2>\n

A little over 86% of Australians using SQ’s solar quotes service in July who had a system size in mind were after a 6kW system or bigger – around the same as in June. Among this group, approximately 52% were looking at larger than 6kW, down on June’s 56%. Around 36% of those using our service weren’t sure what capacity they needed and requested advice on solar system sizing<\/a>.<\/p>\n

\"Solar<\/p>\n

Purchasing Intent<\/h2>\n

21% of all those who requested quotes were ready to buy a solar power system<\/a> immediately; down from 29% in June and 22% in May. A whisker under 32% were looking to buy within 4 weeks and 47% within 3 months.<\/p>\n

The drop in immediate purchase interest was largely attributable to a rush on the Victorian solar rebate<\/a> in June, which reduced at the beginning of July. However, it remains a great deal; particularly given Victorians can also get the national “solar rebate<\/a>“.<\/p>\n

\"System<\/p>\n

Price Vs. Quality<\/h2>\n

Just under 12% were interested in a \u201ctop quality\u201d (most expensive) in July, up a little on June’s ~11%. 80% wanted a system providing a good balance of cost and quality, while around 8% were interested in a good quality budget system.<\/p>\n

So, where do various brands generally sit on the pricing spectrum? You can see a chart for solar panels here<\/a> and solar inverters here<\/a>.<\/p>\n

Australian Solar Price Index<\/h2>\n

On a related note, keep tabs on what\u2019s happening with system prices in Australia with the SolarQuotes Australian Solar Price Index<\/a>.<\/p>\n

It displays the average price paid over time for rooftop installations across Australia and in individual states based on install date – and is updated in real time. Drill down for statistics on various system sizes, and specific panel and inverter brands.<\/p>\n

Microinverter\/Optimiser Interest<\/h2>\n

20% of enquirers in July expressed an interest in receiving information on adding microinverters or optimisers to a system, up on June’s 19%. You can find out more about microinverters and optimisers here<\/a>.<\/p>\n

Advanced Solar Monitoring<\/h2>\n

Advanced solar monitoring<\/a> enables system owners to see how much electricity is being self-consumed in the home in addition to how much solar energy is being generated. While adding a few hundred dollars to a system purchase, it’s a very useful feature. Last month, a whisker under 42% expressed an interest in consumption monitoring.<\/p>\n

Battery Ready Solar Systems<\/h2>\n

Once again in July, only 7% of quote requests indicated interest in a battery-ready package. While all solar systems are capable of having batteries added at a later date, informing an installer energy storage may be on the horizon can assist with system design.<\/p>\n

\"Battery-ready<\/p>\n

Solar + Battery Installation<\/h2>\n

Around 11% (same as June) were interested in having a battery installed concurrently with a solar installation. The level of interest has remained between the 10% – 12% mark for at least the last 4 months.<\/p>\n

If you’re considering a home battery<\/a>, SQ’s solar and battery calculator<\/a> is a very useful tool for estimating savings and payback – and it will also show you both for the panels and battery separately. Also check out our solar battery comparison table<\/a>, where you can compare specifications of dozens of popular home energy storage systems.<\/p>\n
