Key Factors in Solar Water Heating System Design

  • Hot Water Demand: Accurately assess daily hot water usage to determine the correct collector area and storage capacity.
  • Climate Considerations: System performance varies by region; design must account for sunlight availability, seasonal variations, and freeze protection.
  • System Type: Choose between direct (open-loop) and indirect (closed-loop) systems based on local climate and water quality.
  • Collector Orientation & Tilt: Optimize solar collector positioning to capture the maximum available sunlight year-round.
  • Storage Tank Sizing: Ensure the tank is properly matched to the collector array for consistent hot water supply.

AET Solar Water Heating System Sizing Guidelines

  • Residential Sizing: Typically, 1.5 to 2.5 gallons of storage per square foot of collector area.
  • Commercial & Institutional Sizing: Varies by application—hotels, hospitals, and multi-family buildings require customized calculations.
  • Industrial & Process Heating: Larger systems may require thermal storage tanks and multiple collector arrays for high-demand operations.
