Drawbacks of solar energy are:

• it is not always available

• it is polluting

• it is still quite expensive

• all ot the other options

NGSS.MS-PS3-4

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

Concentrating collectors

• are panels that produce electricity

• are solar panels that use mirrors or lenses

• are flat

• have photovoltaic cells
