WA energy policy: how solar & batteries work in 2026

Three concurrent rules now define every new solar and battery install: federal STC tapers (5-14, 14-28, 28-50 kWh tiers), the WA WEM network procedure with tier 0/1/2 export limits and mandatory CSIP-AUS compliance, and Synergy Battery Rewards paying 70¢/kWh for VPP participation.

The market pattern

The pattern we've seen before

During the 2008-2012 solar panel rebate era, 156 new brands entered the Australian market. Within 5 years, 114 of them (73%) had exited, leaving customers with worthless warranties. With WA battery rebates and May 2026 policy changes, this pattern may repeat.

New factor: May 2026 CSIP-AUS requirements may filter out some fly-by-night brands that can't meet the technical standards. However, budget brands rushing to get SSL-certified before May 2026 still pose warranty risks.

The 2025 rebate rush

In the 12 months around the July 2025 rebate start (Nov 2024 – Oct 2025), the register added 608 new battery listings — nearly 4x the prior annual rate. Of these, 73% came from brands less than 2 years old in Australia.
