Solar Pool Pumps & Koi Pond Pumps
A solar pool pump filters and circulates swimming pool or koi pond water using energy from solar panels — usually as a drop-in replacement for your existing AC pool pump on the same plumbing. Run filtration for free in daylight, avoid the startup surge on your home inverter, and keep water moving through load shedding; hybrid models switch to mains at night for 24-hour koi pond circulation.

How Do Solar Pool Pumps Work?
Solar pool pumps connect to photovoltaic panels through an MPPT controller and mount on the same suction and return lines as a conventional pool pump. The controller matches motor speed to available sunlight, so filtration intensity rises through the middle of the day when solar yield is highest — ideal for turning over pool volume without running a large AC motor on the grid. Pure solar models run only from panels; hybrid pool pumps add an AC input so the unit can filter on mains power after dark, which matters for koi ponds that need continuous circulation.
Why Replace an AC Pool Pump with Solar?
Pool pumps are among the heaviest daytime loads on a property. Replacing your AC unit with a solar pool pump keeps the same filter, chlorinator, and pool cleaner connections while shifting most of the running cost to free solar energy.
Cut Pool Electricity, No Inverter Spike
Daytime filtration is powered directly from your panels, which can remove a pool pump entirely from your grid bill. Because the motor ramps through the solar controller, you avoid the sharp inrush current that a typical AC pool pump places on a backup inverter when load shedding ends and everything switches on at once.
Filtration During Load Shedding
When the grid is off, a solar pool pump keeps filtering as long as there is sunlight — so your pool does not sit stagnant through every stage. For koi ponds that need overnight flow, a hybrid pool pump automatically switches to mains power after dark to maintain aeration and water movement.
Drop-In AC Pool Pump Replacement
Install on the existing pool pump pad: same inlet and outlet unions, same filter loop, compatible with standard pool cleaners and automatic chlorinators. Solar pool pumps do not heat water — they circulate and filter only.
Where Solar Pool & Koi Pond Pumps Are Used
Swimming Pools
Residential and commercial pools use a solar pool pump to meet turnover targets — typically circulating the full pool volume twice in 24 hours based on around six hours of peak solar pumping. Size the pump to your pool litre capacity and pipe run.
Koi Ponds & Fish Ponds
Koi and ornamental fish ponds depend on constant filtration and surface agitation for oxygen. A solar pump handles daytime turnover; a hybrid koi pond pump continues on grid power at night so fish are not left in still water when the sun goes down.
Pool Cleaners & Chemical Dosing
Solar and hybrid pool pumps work with suction-side and robotic pool cleaners on the same plumbing. Hybrid units can also run scheduled night cycles for chlorinator dosing when chemical treatment is required after hours.
Sizing & Pump Types
How to Size a Solar Pool Pump
Pump capacity is based on circulating the pool water twice in a 24-hour period, assuming roughly six hours of maximum solar pumping per day.
Example: 5 m × 3 m × 1.2 m × 1000 = 18,000 Litres
Solar vs. Hybrid Pool Pumps
A solar pool pump runs 100% from panels via an MPPT controller — no household inverter required. A hybrid pool pump accepts solar DC and mains AC, using free solar by day and switching to grid power at night or in heavy overcast — the preferred choice for koi ponds and pools that need reliable overnight filtration.
Installation note: These pumps are drop-in replacements for your existing AC pool pump and work with standard pool cleaners. They circulate and filter water only — they do not heat the pool.
