Unpacking crucial sub-segments of the solar+storage market

Successful manufacturers offer products that meet the needs of the market. The same is true for manufacturers of energy storage systems, as it is for battery wholesalers and retailers.

The solar battery is dynamically growing and reshaping. It pays to understand each market segment, so that investments of time, money and resources are well placed.

While researching the 2023 SunWiz Annual Australian Battery Market Report, some distinct key market sub-segments emerged.

Battery-only sales

- - Solo-ESS: Batteries installed without PV
  - ESS-Upgrade: Batteries added to an existing ESS
  - ESS-Retrofit-to-PV: Batteries retrofit to an existing & unchanged PV system

Solar + Storage Sales

New ESS+Larger-PV: Batteries retrofit to an existing PV system with capacity added
New ESS+Replaced-PV: Batteries sold with a new PV system that replaces an existing smaller PV system
New ESS+New PV: Batteries sold with a new PV system at a site that didn’t previously host a PV system

This is illustrated in the following Venn diagram which shows the numerous intersections between Existing PV (purple), New PV in 2022 (blue), and New Batteries (yellow).

Here’s some interesting information about these market sub-segments.

About 1 in three ESS systems are retrofit to an existing PV system. This is higher in SA & NSW.
20.5% of PV systems installed in 2022 were done at a site that had an existing PV system. A large number of these occurred concurrently with addition of a battery.
The typical customer will install a larger battery system when retrofitting to an existing PV system
The typical customer when buying a solar+storage system buys a smaller battery than if they were retrofitting. However, this does vary by state.
The typical customer will install a larger PV system when installing a battery, compared to a non-ESS PV installation.

An in-depth breakdown of these market segments is covered within the 2023 SunWiz Annual Australian Battery Market Report. View a sample here: https://www.sunwiz.com.au/battery-market-report-australia-2023/

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.
