Solar Power Questions and Answers
- 1.
Solar thermal technologies can be used for water heating, space heating, space cooling, and process heat generation.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Solar thermal technologies utilize solar energy to generate heat, which can be used for various applications, including water heating, space heating, space cooling, and process heat generation. Solar collectors, such as flat-plate collectors, evacuated tube collectors, and parabolic troughs, absorb solar radiation and convert it into heat energy. This heat can be used directly for heating water in residential or commercial buildings, providing space heating, or cooling spaces using absorption chillers. Additionally, solar thermal energy is utilized in industrial processes that require high-temperature heat, such as chemical manufacturing or food processing.Rate this question:

- A.
True
- B.
False
Correct Answer
A. TrueExplanation
MIT's Solar House #1, constructed in 1939, was a pioneering project in solar energy that employed seasonal thermal storage for year-round heating. The house was designed to collect solar heat during the summer months and store it in insulated water tanks for use during the winter. This method allowed the house to maintain a comfortable temperature throughout the year without relying on conventional heating systems. The Solar House #1 demonstrated the potential of solar energy for sustainable residential heating and paved the way for future advancements in solar thermal technologies.Rate this question:

What can be used to make saline or brackish water potable? The first recorded instance of this was by 16th century Arab alchemists. Individual still designs include single-slope, double-slope (or greenhouse type), vertical, conical, inverted absorber, multi-wick, and multiple effect. These stills can operate in passive, active, or hybrid modes.
- A.
Solar smelting
- B.
Solar distillation
- C.
Solar treatment
- D.
Solar heating
Correct Answer
B. Solar distillationExplanation
The correct answer is "Solar distillation." Solar distillation is a process that uses solar energy to purify saline or brackish water, making it potable. This method involves evaporating water using solar heat and then condensing the vapor to collect clean water, leaving behind salts and impurities. Solar stills, such as single-slope, double-slope, and multi-wick designs, can be used for this purpose. The technique was first documented by Arab alchemists in the 16th century and can operate in passive, active, or hybrid modes, depending on the setup.Rate this question:

What is a concentrating technology employed by the Solar Kitchen in Auroville, India, where a stationary spherical reflector focuses light along a line perpendicular to the sphere's interior surface, and a computer control system moves the receiver to intersect this line. Steam is produced in the receiver at temperatures reaching 150 °C and then used for process heat in the kitchen.
- A.
Solar cusp
- B.
Solar spoon
- C.
Solar bowl
- D.
Solar cap
Correct Answer
C. Solar bowlExplanation
The correct answer is "Solar bowl." The Solar Kitchen in Auroville, India, utilizes a solar bowl, a type of concentrating solar technology. This system features a large, stationary spherical reflector that focuses sunlight along a line. A computer-controlled receiver moves to intersect this focal line, where it captures concentrated sunlight. The focused light generates high temperatures, producing steam that can reach up to 150 °C. The steam is then used for cooking and other heating processes in the kitchen, making it an effective application of solar energy for community use.Rate this question:

Solar technology is capable of processing heat through which of the devices listed?
- A.
Solar receptor
- B.
Parabolic plate
- C.
Solar panel
- D.
Parabolic dish
Correct Answer
D. Parabolic dishExplanation
The correct answer is "Parabolic dish." A parabolic dish is a type of concentrating solar technology that uses a parabolic-shaped reflector to focus sunlight onto a central receiver. This design allows for the concentration of solar energy onto a small area, generating high temperatures that can be used for various applications, such as generating electricity, heating water, or even cooking. The parabolic dish is highly efficient in capturing and focusing sunlight, making it a powerful device for solar heat processing.Rate this question:

What technologies convert sunlight into electricity using solar cells or concentrated solar power systems?
- A.
Photovoltaics (PV) and Concentrated Solar Power (CSP)
- B.
Solar panels and wind turbines
- C.
Electrical grids and transformers
- D.
Geothermal and hydropower systems
Correct Answer
A. pHotovoltaics (PV) and Concentrated Solar Power (CSP)Explanation
The correct answer is "Photovoltaics (PV) and Concentrated Solar Power (CSP)." Photovoltaic technology uses solar cells to convert sunlight directly into electricity through the photovoltaic effect, while Concentrated Solar Power (CSP) systems use mirrors or lenses to focus sunlight onto a small area to generate heat, which is then converted into electricity. Both PV and CSP are essential technologies for harnessing solar energy for power generation.Rate this question:

A solar cell, or ______ cell (PV), is a device that converts light into direct current using the photoelectric effect.
- A.
Solar
- B.
Photovoltaic
- C.
Electromagnetic
- D.
Thermoelectric
Correct Answer
D. ThermoelectricExplanation
The correct answer is "Photovoltaic." A solar cell, also known as a photovoltaic (PV) cell, converts light directly into electricity using the photoelectric effect. This effect occurs when photons from sunlight strike a semiconductor material (such as silicon), causing electrons to be released and flow as an electric current. PV cells are the building blocks of solar panels and are widely used to generate electricity for homes, businesses, and utility-scale solar power plants.Rate this question:

A ______ consists of a linear parabolic reflector that concentrates light onto a receiver positioned along the reflector's focal line. The reflector is made to follow the Sun during the daylight hours by tracking along a single axis.
- A.
Solar array
- B.
Solar dish
- C.
Solar trough
- D.
Solar panel
Correct Answer
C. Solar troughExplanation
The correct answer is "Solar trough." A solar trough is a type of solar concentrator that uses a linear parabolic reflector to focus sunlight onto a receiver located along the reflector's focal line. The reflector tracks the sun's movement along a single axis throughout the day to maximize the amount of sunlight captured. The concentrated sunlight heats a fluid in the receiver, which can then be used to generate electricity or for other thermal applications. Solar troughs are commonly used in concentrated solar power (CSP) plants.Rate this question:

______, or "thermovoltaic" devices convert a temperature difference between dissimilar materials into an electric current. First proposed as a method to store solar energy by solar pioneer Mouchout in the 1800s.
- A.
Photovoltaic
- B.
Solar thermal
- C.
Thermoelectric
- D.

Correct Answer
C. ThermoelectricExplanation
The correct answer is "Thermoelectric." Thermoelectric devices, also known as "thermovoltaic" devices, convert a temperature difference between two different materials into an electric current. This process is based on the Seebeck effect, where a voltage is generated in response to a temperature gradient across the materials. Solar pioneer Augustin Mouchout proposed using thermoelectric devices in the 1800s as a way to store solar energy by converting excess heat into electricity.Rate this question:
