question
In the solar panel system presented in the video, which of the following was necessary to generate usable electrical current for a home? A- Electrical energy had to be stored in batteries for several days. B- DC power had to be converted to AC. C- The electrical energy had to be converted to nuclear energy. D- The heat of the sun had to be used to generate steam.
answer
B- DC power had to be converted to AC. DC power is not usually used in home. Thus, the DC current must be converted to AC, which is the standard in homes.
question
Which of the following best describes the energy conversion sequence in the solar panel system described in the video? A- Photons carrying energy from sun chemically react with silicon crystals to generate a flow of electrons. B- Electrons, carrying energy from the sun, are collected by thin chemical wafers, which concentrate the electrons to make electricity. C- Electrons, carrying energy from the sun, are focused by lenses onto wires, which carry the electrons as electricity. D- Photons, carrying energy from the sun, are used to create steam that turns turbines to generate electricity.
answer
A- Photons carrying energy from the sun chemically react with silicon crystals to generate a flow of electrons
question
Which of the following would indicate that a home is using solar power to generate electricity and is NOT using batteries? A- There are water pipes running to and from the solar panels on the home. B- There are small plumes of smoke drifting away from the solar panels on the home. C- There are solar panels on the roof and power lines going to the home. D- There are solar panels on the roof and NO power lines going to the home.
answer
C- There are solar panels on the roof and power lines going to the home. ā€¢ When the solar panel system is not generating enough electricity, or any at all at night, the home can draw upon the power grid. Therefore, the home does not require or use batteries for backup.
question
If a home uses a large supply of solar panels to generate electricity, but has no battery system, surplus electricity that is produced is usually ______ A- released harmlessly into the ground B- used to power chemical reactions that generate water for the home C- released into the power grid for others to use, generating a credit to the homeowner D- used to pump water high up into a tank to store the energy
answer
C- Releases into the power grid for others to use, generating a credit to the homeowner
question
Which of the following is a challenge to using solar-generated electricity in places not connected to a power grid? A- the reliance upon fossil fuels to power the system B- the generation of toxic fumes by the solar panel system C- the lack of efficient and inexpensive battery technology D- the limited supply of silicon to make the wafers used in solar panels.
answer
C- The lack of efficient and inexpensive battery technology. ā€¢ Current research in battery technology hopes to address this important need, which may also benefit the electric car industry.
