Solar enegy can be converted into

• heat, electricity and power

• heat

• electricity and heat

• electricity

Drawbacks of solar energy are:

• it is not always available

• it is polluting

• it is still quite expensive

• all ot the other options

Solar power for heating is passive when

• no mechanical components are used to move heat around

• there is no sun (at night)

• in winter

• some mechanical components are used to move heat around

Solar power for heating is active when

• no mechanical components are used to move heat around

• some mechanical components are used to move heat around

• it is very sunny and hot

• it produces electricity

What are solar thermal collectors used for?

• To produce electricity

• To heat water or homes

• To produce electricity and warm up water and homes

• Neither of the other options

Concentrating collectors

• are panels that produce electricity

• are solar panels that use mirrors or lenses

• are flat

• have photovoltaic cells

In solar thermal collectors water

• is concentrated in a tank

• passes in tubes right under the surface

• all false

• can be cooled down
