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.
Discover the operational principles and realistic performance expectations of your
energy-efficient water pump system throughout the seasons. This guide helps you
understand your system's capabilities and how to maximize its potential.
1. Operating Principles
Energy Collection
The panel captures sunlight and converts it to electrical energy
Energy powers the pump directly or charges the battery (in backup models)
System activation depends on light intensity and system type
Performance varies significantly with weather conditions
System Types
Direct Systems: Function only with sufficient direct sunlight
Battery-Backed Systems: Store energy for more consistent operation
Hybrid Systems: Combine immediate operation with energy storage
Each type offers different benefits based on your specific needs
2. Realistic Performance Expectations
Direct Systems Performance
Operation strictly dependent on available sunlight
Flow varies continuously with passing clouds
May start and stop multiple times on partly cloudy days
Strongest performance during midday hours with direct sun
No operation during evening or heavily overcast conditions
Battery-Backed Systems Performance
More consistent operation throughout the day
Continues running during brief cloudy periods
Provides operation after sunset (typically 1–8 hours depending on model)
Maintains steadier flow rate regardless of minor light variations
May include adjustable flow settings and timer functions
3. Seasonal Performance
Summer Performance (May to August)
Peak performance period for all system types
Direct Systems: Operation possible from early morning to evening on clear days
Battery Systems: Consistent daytime operation plus evening hours
Maximum flow rates achieved during direct midday sun
