How to use your pool pump on solar you may ask?
Can I run my pool pump on solar?
You have two main ways to power your pool pump on solar power:
1) Disconnect Your Pool Pump from the Grid
One option is to install a DC pool pump and dedicate 4–6 solar panels to run it. These solar panels connect directly to the pump through power electronics, allowing it to operate whenever the sun is shining. Plus, you can still claim solar rebates for these panels, even though they aren’t tied to the grid!
Advantages:
✅ Your pool pump on solar runs independently from the grid, so you won’t have to pay for electricity.
✅ Since the solar panels aren’t connected to the grid, you don’t need approval from your electricity provider to install them.
✅ These additional solar panels won’t count toward the grid’s limit on solar panel installations.
✅ If you’re on a premium feed-in tariff, this setup lets you keep your benefits while running the pool pump without affecting your tariff.
✅ Panels can be placed near the pool instead of using up valuable roof space.
✅ The pump’s operation naturally aligns with the seasons—it runs more in summer (when the pool is in use) and less in winter.
✅ This setup can be especially useful if:
- Your solar system has a size restriction (e.g., a 5kW inverter limit in Western Australia).
- You plan to install battery storage for your home’s solar power, allowing you to use a smaller battery.
- You live in an off-grid area where reducing battery and generator use is important for cost efficiency.
Disadvantages:
❌ Requires replacing your existing pool pump with a compatible DC model.
❌ If your solar panels produce more energy than your pump needs, the excess energy goes unused.
❌ If your panels don’t generate enough power, you’ll need to add more panels since you can’t rely on the grid for extra energy.
2) Use Your Grid-Connected Solar System to Power Your Pool Pump
If you install a sufficiently large solar system for your home (at least 6kW), it can power your pool pump on most days except during heavy cloud cover. Just set your pool pump timer to run close to midday when solar production is highest—e.g., from 11 AM to 1 PM in winter and 10 AM to 3 PM in summer.
Advantages:
✅ No need to replace your pool pump or run additional wiring from your panels.
✅ All solar power is used efficiently—either by the pump, other household appliances, or sent back to the grid for a feed-in tariff.
Disadvantages:
❌ On cloudy days, your pool pump may draw power from the grid.
❌ You need a large solar system (at least 6kW) to cover both household and pool pump energy needs.
