Characteristics of Energy Storage System Customers

Successful salespeople go where the customers are, and sell them what they want to buy.

Sales of solar batteries increased by 55% in 2022, according to the recently released 2023 SunWiz Annual Australian Battery Market Report. And the market is expected to grow further from there.

Sellers of Energy Storage Systems (ESS) will get the greatest reward for their efforts by targeting the customers that are most likely to buy, with the products and system sizes that are most in demand.

SunWiz data shows a shift towards 9kWh and 14kWh battery sizes, so you should be selling more of those.

And it makes sense to specialise in battery sales. The chart below shows SunWiz analysis of 2022 Victorian Solar Homes Program rebate data, plotting the % of battery rebates (vertical axis) allocated by retailer classification (horizontal axis). Retailers are classified by their degree of battery specialisation – the % of total rebates allocated that are for ESS. This chart shows (with conclusions supported by SunWiz proprietary data):

16% of VSHR ESS rebates come from ESS-exclusive (or near-exclusive) retailers
25% of VSHR ESS rebates come from retailers that do more ESS installations than PV installations (as-rebated)
49% of VSHR ESS rebates come from retailers for whom ESS represents less than 25% of their rebates.

The 2023 SunWiz Annual Australian Battery Market Report also includes customer demographics, some of which we’re fortunate to be able to share here.

This chart (data courtesy Solar Victoria) shows the percentage of rebates by age group, separately for batteries (blue) and PV (orange). The line thickness indicates the household income range.

Here’s some takeaways from this data source:

Purchasers of batteries are much more likely to be older than purchasers of PV
Purchasers of batteries are much more likely to be lower income households.

This data suggests that older retirees are more likely to purchase a battery system. Before everyone rushes out to target that demographic, note that this datasource relates to the Solar Victoria rebate program, which excludes households with annual income greater than $180k. SunWiz assessment shows this rebate program forms 50% of the Victorian market, indicating there is another large distinct demographic that is purchasing batteries.

Interval Meter Data Tool Disclaimer

The Interval Meter Data Tool is designed to convert standard form meter data for the OpenSolar platform.

Users are responsible for meeting the requirements of the data that needs to be uploaded to the tool, which extends to but is not limited to

The completeness and accuracy of the data
Ensuring that there are no missing records
Uploading the data in one of the compatible intervals (15m, 30m or 1h).

Data uploaded to the Interval Meter Data Tool should not contain multiple datasets. In the case an excel file is uploaded, only the first sheet will be considered.

The accuracy of the output is dependent on the user’s dataset, therefore SunWiz does not guarantee the accuracy of the output.

The user must acknowledge that the output of the tool is beyond the control of SunWiz, and they must ensure that the data is accurate on their own behalf.

In the event that the program runs into an issue, the user will be issued with warnings or solutions to address or resolve the issue.

If the user requires additional support, they can avail it as a separate service from SunWiz

Warranties on performance

The Interval Meter Data tool from SunWiz attempts to convert most frequently occurring types of standard meter data file types in specific formats for the purpose of being used on the OpenSolar platform. Unless mentioned otherwise, SunWiz does not extend any guarantee of any kind, either expressed or implied, on the limited success of the Interval Meter Data Tool and the extent of it’s automation. Depending on the user’s upload, the program may require additional inputs, the training for which is not included in the purchase of this service and can be purchased separately.

Input requirements

The Interval Meter Data Tool accepts data in the 15-minute, 30-minute and 60-minute(hourly) intervals. In case the file is uploaded in an excel format (*.xls, *.xlsx, *.xlsm), only the first sheet of the file will be considered. Our tool is required to accept raw meter data, usually highlighted as ‘E’ data in its standard format; and therefore SunWiz does not guarantee that all data formats will be accepted.

For complete automation, the file must adhere to an acceptable standard format. In the case of an issue, the user will be provided with instructions by the tool on how it can be resolved. Warnings will be issued if the data is incompatible, incomplete with missing records and if multiple datasets are uploaded at once.
