WA energy policy in 2026
Three rules shape every new solar and battery install in WA.
The market pattern
73%of new brands gone
within 5 years
During the 2008–2012 solar panel rebate era, 156 new brands entered Australia. Within 5 years, 114 had exited, leaving customers with worthless warranties. With WA battery rebates and the May 2026 policy changes, the pattern may repeat.
New factor: CSIP-AUS requirements from May 2026 may filter out brands that can't meet the technical standard. Budget brands that rushed SSL certification before the deadline still pose warranty risks.
149 brands · 3,742 CEC-listed models
CEC data as at September 2026. 3,532 of the 3,742 models are within their current approval window.

Models on the register
Models by size
Monthly counts come from Clean Energy Council approved product listings. The April 2026 spike is a register re-issue batch ahead of the 1 May 2026 compliance changeover, not organic new listings. Counts include every capacity variant, so one series can appear many times.
Price history
Prices fall as brands pour in during a rebate. When rebates shrink, brands leave.
Prices dropped 85% as 156 brands entered. After rebates reduced, 73% of brands exited within 5 years.
Prices dropped 44% as CEC listings grew 280% (2020 to Jul 2025). WA rebates from July 2025 sped up new entries.
When rebates reduce (expected 2027 onwards), history suggests many new entrants will exit the market.
Years since earliest CEC-listed product, any type
Tenure counts batteries, inverters and panels. A longer track record means someone is more likely to be around for a 10-year warranty.
