ARRAY Adds Aeeris Hail Alerts to Stow Australian Solar Trackers

• ARRAY Technologies will feed hail forecasts from Aeeris unit Early Warning Network into SmarTrack to stow Australian solar trackers automatically.
• Hail caused 73% of solar losses by damage amount in insurer kWh Analytics' database, from only 6% of incidents.
• Neither company disclosed financial terms or named the first Australian projects to use the service.

ARRAY Technologies will use hail forecasts from Aeeris' Early Warning Network (EWN) to stow solar trackers in Australia without operator input, the companies said on Oct. 26. Neither disclosed financial terms, and Aeeris did not flag its ASX filing as price-sensitive.

EWN becomes ARRAY's hail intelligence provider in Australia. Its detection and forecasting systems flag hail risk at solar sites. SmarTrack Hail Alert Response, part of ARRAY's tracker software platform, then turns modules to their maximum protective tilt before the hail arrives. EWN pairs Australia-wide radar with meteorologist checks and its own detection algorithms, Aeeris said.

According to ARRAY's product page, a weather provider supplies the storm's forecast position, hail probability and track. When severe hail looks likely, a site alert goes to the on-site SmarTrack controller. Trackers start moving 30 minutes ahead and tilt to maximum angle away from the storm, or to the closest maximum tilt. ARRAY says VDE Americas validated the system.

ARRAY says its grid-powered AC motors and wired communications stow more reliably than battery and wireless systems, which extreme weather can disrupt.

Hail stow in numbers

• 30 minutes before high-probability hail, SmarTrack starts moving trackers into the defensive position, ARRAY says.
• 77° is the stow angle of ARRAY's DuraTrack Hail XP tracker, leaving modules 13° short of vertical (list.solar calculation).
• 73% of solar losses by damage amount came from hail, from just 6% of incidents, in insurance firm kWh Analytics' 2025 Solar Risk Assessment.
• 42 times the average non-hail loss: roughly what one hail incident cost in that database (list.solar calculation).
• 3 GW of large-scale solar won approval from Australia's Clean Energy Regulator in 2025, 20% above the 2018 record (list.solar calculation).
• 2 GW of utility-scale solar from 18 projects was commissioned in Australia in 2025, double the 2024 figure, the Clean Energy Council says.

"This integration greatly improves the bankability of these projects," Francesca Lucia Falcone, ARRAY's business development director for Asia-Pacific, said in a statement. ARRAY says the system gives operators a way to show insurers and financiers how they manage hail risk.

ARRAY has not named the first Australian sites to receive the EWN feed. Existing DuraTrack and OmniTrack plants can add Hail Alert Response by installing a SmarTrack controller linked to ARRAY's cloud data platform, the company says.
