Purdue COURSE EAPS 120 In the solar panel system presented in the video

Part AIn the solar panel system presented in the video, which of the following was necessary to generate usable electrical current for a home?The heat of the sun had to be used to generate steam.Electrical energy had to be stored in batteries for several days.The electrical energy had to be converted to nuclear energy.DC power had to be converted to AC.Part BWhich of the following best describes the energy conversion sequence in the solar panel system described in the video?Photons carrying energy from the sun chemically react with silicon crystals to generate a flow of electrons.Photons, carrying energy from the sun, are used to create steam that turns turbines to generate electricity.Electrons, carrying energy from the sun, are collected by thin chemical wafers, which concentrate the electrons to make electricity.Electrons, carrying energy from the sun, are focused by lenses onto wires, which carry the electrons as electricity.Part CWhich of the following would indicate that a home is using solar power to generate electricity and is NOT using batteries?There are solar panels on the roof and power lines going to the home.There are small plumes of smoke drifting away from the solar panels on the home.There are solar panels on the roof and no power lines going to the home.There are water pipes running to and from the solar panels on the home.Part DIf a home uses a large supply of solar panels to generate electricity, but has no battery system, surplus electricity that is produced is usually __________.used to pump water high up into a tank to store the energyreleased into the power grid for others to use, generating a credit to the homeownerused to power chemical reactions that generate water for the homereleased harmlessly into the groundPart EWhich of the following is a challenge to using solar-generated electricity in places not connected to a power grid?the limited supply of silicon to make the wafers used in solar panelsthe reliance upon fossil fuels to power the systemthe lack of efficient and inexpensive battery technologythe generation of toxic fumes by the solar panel system
