Operations
 Flat-Plate Collector
• weatherproof boxes with dark absorber plate to collect
sunlight

 Integral Collector-Storage Systems
• uses tubes and tanks to take warm water heated by flat plate
collector to conventional back-up water heater
 Evacuated-Tube Solar Collectors
• glass tubes that inhibit radiative heat loss
Technological Obstacles
 Needs warm climate with large
amounts of sun and rarely freezes
 No sunlight = No warm water
 Solar plates are expensive and
fragile
Political and Economic
Obstacles
 Expensive installment and repairs
throughout the entire system
 Government regulation and
neighborhood covenants
Environmental Impacts
 No negative environmental
impacts
• The solar water heating for the home drastically reduces a
family’s utility bills and environmental impact.
• During the winter, the solar heater eliminates the air pollution
created by using traditional heating systems.
