Solar electricity plans in Western Australia
Feed-in tariff rates in WA currently range from 2.5 to 10 (DEBS tiered) cents per kWh depending on your retailer. Your distribution network is Western Power / Synergy, Horizon Power.
Our take on solar in WA
Perth averages 5.5 peak sun hours per day, among the highest of any Australian capital. Synergy's Distributed Energy Buyback Scheme (DEBS) pays a tiered feed-in rate: higher for exports between 3pm and 9pm (peak demand) and lower at other times. This rewards households that can time their exports using battery storage. The Midday Saver tariff (A3) charges as low as 9 cents per kWh between 9am and 3pm, which actually reduces the self-consumption value of solar during those hours but can be offset by lower grid costs overall. WA has capped new solar exports to manage grid stability, so some new installations may face export limits.

Self-consumption first. Every kWh you use from your panels avoids buying at 25 to 40 cents from the grid. Exporting earns only 2.5 to 10 cents. Shift your dishwasher, washing machine, pool pump, and EV charging to daylight hours.
Compare the total estimated annual cost, not just the feed-in rate. A plan with a high feed-in rate but high usage rate can cost more overall than a plan with a moderate feed-in rate and low usage rate.
