A) indirect gain
B) isolated gain
C) direct gain
D) photovoltaics

Answer 1

D

Question 2

In an active solar heating system, the heat is absorbed using solar radiation and transferred directly to a storage device or to the interior of the structure.

Answer 2

True

Question 3

_____ for solar pool-heating systems are constructed using a heavy-duty plastic that has been treated with an ultraviolet light inhibitor.

A) Unglazed collectors
B) Glazed collectors
C) Tempered glass collectors
D) Aluminum collectors

Answer 3

A

Question 4

What commonly used heat transfer medium used in solar collectors has a boiling point of 212°F and is nontoxic, inexpensive, and capable of containing a high mineral content.

A) Propylene
B) Antifreeze
C) Water
D) Ethylene

Question 5

Solar collectors should be cleaned when they are hot.

Question 6

Of all the renewable energy sources, solar energy has the most potential because it could supply thousands of times more energy than the world currently consumes.

Question 7

Unlike traditional water heater tanks, the efficiency of solar water storage tanks is not increased by installing a water heater blanket.

Question 8

For a liquid-based active solar heating system, the _____ is a device that uses the greenhouse effect and direct sunlight to heat up a copper plate containing heat transfer tubing.

A) Trombe walls
B) solar key
C) solar collector
D) heat distributor

Question 9

All electricity that is produced by a solar array is in the form of direct current.

Question 10

_____ is nothing more than a term used to describe a range of electromagnetic radiation that is detectable from the human eye.

A) Wave-particle duality
B) Light
C) Photovoltaic
D) A photon

Question 11

Solar collectors should be cleaned with the same chemicals used in _____ .

A) window washing
B) bathtubs
C) clothes washers
D) paint removal

Question 12

What type of energy is derived from moving water?

A) biomass
B) hydro
C) geothermal
D) solar

Question 13

_____ is a heat transfer medium used in solar collectors and is used in air-conditioning equipment as well as some types of heat pumps.

A) Glycol
B) Silicone
C) Hydrocarbon oil
D) Refrigerant

Question 14

Most workers on the job site do not need to refer to the codes much during construction because architects and engineers who design the buildings usually see that the code requirements are covered by their designs.

Question 15

A heat engine is a thermal system that converts heat into mechanical work by transforming liquid from a lower temperature to a higher temperature.

Question 16

It is the responsibility of the heat transfer fluid to move the heat from the collector to the heat exchanger (located in the storage tank).

Question 17

For solar hot water production, when the same water (output from the collector) is used for dual purposes, typically heating and hot water production, this is referred to as a(n) _____.

A) optional outcome
B) open system
C) drain-back solution
D) closed system

Question 18

A _____ is a system that uses both energy from the power grid and a solar energy system.

A) grid-connected system
B) hybrid system
C) stand-alone system
D) stand-alone hybrid system

Question 19

The solar constant is the energy generated by ocean tides.

Question 20

A stand-alone grid-connected system is basically the same as a grid-connected system, with the exception that they have an added storage device; typically in the form of a battery system.
