OperationsOperations 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 Technological ObstaclesObstacles

Needs warm climate with large amounts of sun and rarely freezes No sunlight = No warm water Solar plates are expensive and fragile

Political and Political and Economic ObstaclesEconomic Obstacles

Expensive installment and repairs throughout the entire system Government regulation and neighborhood covenants

Environmental Environmental ImpactsImpacts 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.
