Understanding market patterns to protect your investment
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.

May–Dec 2026 (was 8.4×)
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.
