Solar Thermal Systems Quiz

What is the primary function of a solar thermal system?

• To generate electricity

• To heat water or air using solar energy

• To cool buildings

• To provide lighting

In which type of solar thermal system is a flat plate collector (FPC) primarily used?

• Passive solar heating

• Solar water heating

• Concentrated solar power

• Photovoltaic systems

Which is a key component of a flat plate collector (FPC) in a solar water heating system?

• Reflector

• Absorber plate

• Solar cells

• Inverter

What material is commonly used for the absorber plate in flat plate collectors?

• Copper

• Aluminum

• Steel

• Plastic

What is the function of the glazing in a flat plate solar collector?

• To protect the collector from wind

• To prevent heat loss and allow solar radiation to enter

• To store heat generated by the system

• To reflect sunlight

What does the insulation in a solar water heater do?

• Absorb heat from the sun

• Prevent heat loss from the collector

• Increase the weight of the system

• Reflect solar radiation back to the absorber plate

What is the purpose of the heat exchanger in a solar water heating system?

• To store solar energy

• To transfer heat from the solar collector to the working fluid (usually water)

• To increase the temperature of the absorber plate

• To regulate the flow of water

A common fluid used in solar thermal systems for heat transfer is:

• Air

• Water

• Oil

• Freon

What does 'thermal storage' refer to in a solar thermal system?

• The collection of solar radiation

• The storage of heat for use when solar energy is not available (e.g., at night)

• The use of batteries to store electricity

• The storage of excess water from the collector

What is the main advantage of a flat plate collector (FPC) over evacuated tube collectors?

• Lower cost and easier to install

• Higher efficiency in cold climates

• Ability to concentrate solar radiation

• Smaller physical size
