Solar Panels for a SA Home with a Pool: What Size Do You Need?
Pool pumps are one of the biggest energy consumers in a South Australian home, often adding $600–$1,200 to annual electricity bills. The good news: solar is one of the most effective ways to run a pool for near-zero cost. With SA's excellent solar resource and the ability to schedule your pool pump to run during the day, a well-sized system can essentially offset pool running costs entirely. This guide covers what size solar system you need, how to schedule your pump, and what to expect in SA.
What You Need to Know
Size for Pool + Household Load
For a typical SA home with a 0.75–1.5kW pool pump running 6–8 hours per day, a 10kW system is usually the sweet spot — enough to cover pool consumption and a full household during daylight.
Schedule Your Pump to Daytime Hours
Modern variable-speed pool pumps can be programmed to run between 9am–3pm — directly consuming your solar generation rather than exporting at 4–10c/kWh.
Payback Is Faster with Pool Loads
Because pool pumps run daily and consume consistent daytime power, they're ideal solar loads. SA homeowners with pools often see full payback in 3–4 years on a 10kW system.

Frequently Asked Questions
What size solar system do I need for a house with a pool in SA?
For most SA homes with a pool, a 10kW system is recommended. This covers the pool pump (typically 0.75–1.5kW running 6–8hrs/day) plus full household daytime usage with minimal grid import.
Should I get a battery as well?
If you want to extend solar self-consumption into the evening, a 10kWh battery can store excess daytime generation. However, with a pool load running during the day, export may already be minimal without a battery.
How much does a 10kW solar system cost in SA?
A quality 10kW solar system in SA typically costs $8,000–$10,000 installed after STCs. Get a personalised Jousto quote for an exact price based on your roof and location.
Can I claim solar rebates for a home with a pool in SA?
Yes — STCs apply regardless of your end-use load. A 10kW system in SA attracts approximately $3,000–$4,000 in federal STC rebates at current deeming prices.
