Overview
Combines pumping and filtration in one unit for wildlife ponds up to 2000 litres, delivering 1400 LPH from a 25W panel with optional MPPT battery backup.
Set the filter box and pump in position and place the solar panel where it can receive direct sunlight, then size the setup to your pond volume and how much lift you need for circulation or a fountain. This helps you plan the layout and maintenance routine around typical sunlight conditions and seasonal use.
✓ Ponds up to 2000 L (no fish)✓ Up to 1000 L (small fish stock)✓ 1400 LPH flow rate✓ Integrated pump & filter✓ 25 W solar panel✓ Optional battery backup
As with all solar-powered systems, output depends on sunlight availability. Best performance is achieved in direct sunlight, with reduced output during prolonged overcast conditions or outside peak summer months.
Pond Suitability

Solar Power & Filtration System
The system uses a 25 W solar panel to power a DC pump, delivering circulation through the filter stages. Mechanical filtration captures debris, while biological media support beneficial bacteria that help break down waste.
Mechanical Filtration
Foam filters capture solid debris, reducing waste build-up within the pond.
Biological Filtration
Zeolite or gravel media support biological filtration for a balanced pond environment.
Maintenance Access
Designed for straightforward cleaning with accessible filter components.
Optional MPPT Battery Backup
Selected configurations support an optional MPPT battery backup system. Energy collected during sunny periods can be stored and used when light levels drop, helping stabilise operation during variable conditions.
Exclusive MPPT Technology – Developed for Solar Pond Pumps
PowerBee Ltd was the first company to introduce MPPT-managed control systems into small garden and pond solar pumps — a level of solar optimisation previously used mainly in larger-scale applications.
Our MPPT design helps improve energy conversion in variable light, supporting more consistent flow and stronger usable performance in real UK conditions.
Performance reduces as pumping height increases. Figures are indicative and based on controlled testing. Results vary with sunlight, season, and installation.

For strong filtration and circulation, most pond setups benefit from keeping pumping height as low as practical.
