Set the system up by positioning the pump in the water and arranging the solar panel where it can receive direct sunlight, then choose whether to add the optional battery backup for operation beyond daylight hours. This helps you plan the layout and power setup based on how you intend to run circulation across the day.

Improving Water Quality in Large Ponds
Maintaining good water quality in larger ponds depends on consistent circulation and oxygenation. The PowerBee Professional 5250 LPH pump helps reduce stagnant water by moving and aerating water throughout the pond.
Why circulation matters
Stagnant water can lead to low oxygen levels, algae growth, and reduced clarity. Continuous movement supports healthier conditions for aquatic life.
Recommended placement
Install just beneath the water surface
Angle the outlet upward around 45°
Break surface tension for better oxygenation
Create a natural circulation pattern
Ongoing maintenance
Clean regularly for best performance
Check positioning as pond conditions change
Remove debris buildup around the intake
Industrial-Grade Performance
Built for professional applications, this system provides strong flow rates, high head height capability, and efficient solar operation for large-scale projects.
High flow rate
5250 LPH output supports circulation and transfer applications.
100W solar operation
Compatible with a high-efficiency solar panel setup for maximum daytime performance.
Versatile applications
Suitable for ponds, irrigation systems, landscaping, and commercial water management.
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 Flow Rates – Solar vs Battery Operation
Maximum output is achieved in direct sunlight (18V DC). The optional LiFePO₄ battery backup supports operation during cloudy periods or at night, with reduced flow rates due to lower operating voltage (12.8V).

Built to Last
With durable construction and professional-grade components, this pump system is designed for reliable long-term service.
Our pump systems are designed for efficient, year-round operation, delivering best performance during spring and summer. Follow this guide for proper setup, seasonal adjustments, and maintenance to maximize performance and product life.
Discover the operational principles and seasonal performance of your energy-efficient pump system. This guide explains how to maximize its potential through proper positioning and seasonal adjustments.
1. Basic Operating Principle
Direct Solar Operation
The panel captures sunlight and converts it directly into electrical energy
Power flows immediately to the pump without storage
Pump performance directly matches available sunlight intensity
Operation begins automatically when sufficient sunlight is available
2. Seasonal Operation
Peak Season (May to September)
Optimal performance during direct sunlight hours
Flow rate varies with available sunlight
Maximum flow rate achieved in full sunlight
Best performance during clear weather conditions
Shoulder Seasons (March-April, October)
Shorter operational hours with seasonal daylight
Variable performance based on weather conditions
Expect 40-60% of peak season performance
Performance highly dependent on clear days
Winter Operation (November-February)
Limited operation during peak sunlight hours
Expect 5-10% of peak season performance
Performance highly dependent on direct sunlight
Consider removing system during winter months
3. Optimizing Performance
Seasonal Panel Positioning
To maximize energy capture, adjust the panel angle based on the sun's position throughout the year. In the UK:
Winter (November-February): Position at 60° angle
Spring/Autumn (March-April, September-October): Adjust to 40° angle
Summer (May-August): Set at 20-30° angle
Regular seasonal adjustment ensures optimal energy capture.
Critical Installation Factors
Position panel facing south for maximum exposure
Avoid any shading on the panel surface
Clean panel regularly to maintain efficiency
Ensure unobstructed sunlight throughout the day
Performance Expectations
Flow rate varies with sunlight intensity
Operation stops during insufficient light
No nighttime or heavy cloud operation
Performance improves with direct sunlight
4. System Types
Direct Systems
Simple panel-to-pump connection
Operates only during sufficient daylight
Flow rate directly reflects available sunlight
Stops immediately when sun is blocked
Most economical option
Battery-Backed Systems
Includes energy storage capability
Provides more consistent water flow
Continues operation during brief cloudy periods
Can function after sunset for several hours
Often includes timer functionality
5. Maintenance Requirements
Regular Care
Clean panel surface weekly for optimal energy capture
Very impressive flow rate. At first I thought it was too powerful for the stream and waterfall going into the new pond. After having put various obstacles in the stream I think the flow rate is just right. It would be nice to have a flow control adjustment though.
