What is the source of solar energy?
The Sun
What does the prefix "photo" mean?
Light
From which direction does the Sun rise?
East
Potential Energy
Energy stored for later use.
What does the word "solar" mean?

How many forms of solar energy exist?
2
Which form of solar energy produces electricity?
Light/Photovoltaic
In which direction does the Sun set?
West
Circuit
the path of an electric current
The Sun orbits the Earth. True or False?
False
What are the two forms of solar energy?
Light and heat
What device converts light from the Sun into electricity?
Solar Panel
How long does it take for the Earth to orbit the Sun?
365 days or 1 year
Conductor
A device that allows electricity to flow freely
The Sun is _______________ miles from the Earth.
90 million
To capture the most solar energy, which direction do you point a fixed solar panel? (Northern Hemisphere)
South
What are the two particles that work together to create electricity from a solar panel? Where is each from?
Photons from the Sun
Electrons from the solar panel
Does the Sun produce solar energy when it's behind a cloud?
Yes, but not as much reaches the Earth.
Electric Current
A steady flow of electrons
The sunlight we receive for just an hour is enough to generate energy for __________ for the whole world.
1 year
What are the scientific terms for the two forms of solar energy and which is which?
Heat = Thermal
Light = Photovoltaic
What equipment fixes issues with differing voltage between a battery and a device?
Power Manager
At what time of year is the Earth closest to the Sun?
January. It doesn't affect the weather due to the small difference in distance. Our seasonal weather is determined by the tilt of the Earth.
Define AC and DC.
AC or alternating current is what we get from wall sockets. The electrons move back and forth along the circuit.
DC or direct current is what we get from solar panels and batteries. The electrons move around the circuit in a single direction.
