Max. Height 2.1M 1.68M

Optional Battery System (Available)

For consistent operation during cloudy weather or at night, consider the optional battery backup system. It ensures uninterrupted performance and stabilizes water flow even when sunlight is limited. However, note that the battery backup reduces the maximum head height by 20%, which affects the flow rate, as detailed in the table above.

  • Enables operation during low sunlight or nighttime conditions.
  • Ensures a reliable and stable water display under varying weather conditions.
  • Maintains eco-friendly operation with minimal impact on performance.
  • On a bright summer's Day the battery backup enables the pump to run for up to 16 hours.

How Your Pump System Works Guide

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
  • Best charging efficiency for battery models

Spring/Autumn Performance (March-April, September-October)

  • Reduced operational hours with shorter daylight
  • Direct Systems: Expect 40-60% of summer performance
  • Battery Systems: More reliable operation but reduced evening hours
  • Performance varies significantly with weather conditions
  • Panel angle adjustment becomes more critical

Winter Performance (November-February)

  • Significantly limited operation for all systems
  • Direct Systems: May only operate briefly during peak sun (5-10% of summer performance)
  • Battery Systems: Limited daytime operation with minimal evening hours
  • Many customers choose to store system during winter months
  • Performance highly dependent on clear, sunny conditions

4. Advanced MPPT Technology

Our exclusive Maximum Power Point Tracking system maximizes efficiency in more challenged light conditions:

How MPPT Works

  • Continuously optimizes solar panel output
  • Automatically adjusts to changing light conditions
  • Previously only available in industrial systems

30% Efficiency Boost

  • Enhanced performance in lower light
  • Faster battery charging
  • Longer operating hours

PowerBee Innovation

  • First in small pumps
  • Professional-grade technology
  • Sets a new industry standard

5. 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 (Nov-Feb): Position at 60°
  • Spring/Autumn: Adjust to 40°
  • Summer: Set at 20-30°

Critical Installation Factors

  • Panel facing south for max exposure
  • No shading — even partial shade reduces output
  • Clean weekly for max efficiency
  • Sun all day with no obstruction
  • Keep battery units dry & ventilated

6. System-Specific Features

Direct-Powered Systems

  • Maintenance-free operation
  • No moving parts beyond pump
  • Lower upfront cost than battery systems
  • Best for daytime use
  • Ideal for sunny locations

Battery-Backed Systems

  • Operation in variable weather
  • Runs during cloudy periods + evenings
  • Many include timers
  • Low-battery protection
  • Best for constant circulation

7. Maintenance for Longevity

Regular Care

  • Clean panel weekly
  • Clean pump filter monthly
  • Check all connections
  • Inspect cables
  • Adjust panel seasonally

Battery Maintenance

  • Keep battery dry & ventilated
  • Allow full charge cycle periodically
  • Store indoors in extreme cold
  • Check for corrosion
  • Replace after 18–24 months

8. Winter Considerations

Winter Storage Recommendations

  • Remove system during winter
  • Clean before storage
  • Store in frost-free location
  • Battery fully charged
  • Inspect before reinstall in spring

Winter Operation

  • Expect ~5–10% of summer capacity
  • Direct systems may not operate
  • Battery systems offer limited function
  • Panel at 60° angle
  • Protect pump from freezing
