Performance Flow Rates - With and Without Battery Backup

The 70W system delivers powerful water movement in direct sunlight. When operating without battery backup, both maximum head height and flow rates are reduced.

Height Flow Rate (Direct Solar) Flow Rate (Battery Backup)
0m 3,500 LPH 1,400 LPH
0.5m 2,800 LPH 1,200 LPH
1.0m 2,100 LPH 900 LPH
1.5m 1,500 LPH 700 LPH
2.0m 1,000 LPH 400 LPH
2.5m 600 LPH 200 LPH
3.0m 300 LPH 0 LPH
Max Height 3.5m 2.0m

Note: This system is designed for direct solar operation (no battery included). The battery backup column shows potential performance with an optional 12V battery system. Maximum heights represent the pump's lifting capability - for waterfall features, we recommend staying 0.5m below these limits for optimal flow.

Note: Flow rates measured in liters per hour (LPH) under optimal sunlight conditions. Battery backup performance may vary based on charge level.

Optional Battery System (Recommended)

For consistent operation during cloudy weather or at night, consider the optional battery backup system. It ensures uninterrupted performance and stable water flow.

  • Extended operation during low sunlight
  • Prevents start-stop operation in variable sunlight
  • Enhances fountain and waterfall displays

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. 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 is especially important for direct systems.

Critical Installation Factors

  • Position panel facing south for maximum exposure
  • Avoid any shading on the panel surface - even partial shade significantly reduces output
  • Clean panel weekly to maintain maximum efficiency
  • Ensure unobstructed sunlight throughout the day
  • Keep battery units (if applicable) dry and ventilated

5. System-Specific Features

Direct-Powered Systems

  • Simple, maintenance-free operation
  • No moving parts beyond the pump itself
  • Lower initial cost than battery systems
  • Ideal for daytime water features
  • Perfect for locations with consistent sun exposure

Battery-Backed Systems

  • More reliable operation in variable weather
  • Functionality during cloudy periods and evening hours
  • Most models include built-in timer functionality
  • Automatic low-battery protection prevents damage
  • Ideal for consistent water circulation needs

6. Maintenance for Longevity

Regular Care

  • Clean panel surface weekly for optimal energy capture
  • Remove pump filter and clean monthly
  • Check all connections for security and integrity
  • Inspect cables for damage or wear
  • Adjust panel angle with seasonal changes

Battery Maintenance (if applicable)

  • Keep battery unit dry and well-ventilated
  • Allow full charge cycle periodically
  • Store indoors during extreme cold
  • Check connections for corrosion or looseness
  • Replace battery after 18-24 months of use

7. Winter Considerations

Winter Storage Recommendations

  • Consider removing system during winter months (recommended)
  • Clean all components thoroughly before storage
  • Store pump and components in frost-free location
  • For battery systems, store battery fully charged
  • Inspect for wear or damage before spring reinstallation

Winter Operation (if necessary)

  • Expect minimal performance (5-10% of summer capacity)
  • Direct systems may not operate at all on overcast days
  • Battery systems provide more reliable but limited function
  • Adjust panel to steeper 60° angle for low winter sun
  • Protect pump from freezing conditions
