Basic Solar Energy Facts
This material is commonly used in the production of photovoltaic solar cells due to its ability to convert sunlight into electricity efficiently.
A) Silicon
B) Copper
C) Lead
D) Aluminum
A) Silicon
What was the first use of solar energy by people?
What is to light fires?
What percent of sunlight is converted by solar panels into usable energy?
20%
True or False: Renewable Energy can finish in a human lifetime.
False
What are fossil fuels made of?
fossils, ancient plants and animals, dinosaurs
Does Solar Energy decrease or increase your T&TEC electricity bill and why?
Decreases because it uses less power from T&TEC to power devices, it used solar energy to reduce the consumption
This phenomenon, observed when solar panels are exposed to high temperatures, can lead to reduced electrical output over time, a process known as:
A) Photovoltaic degradation
B) Solar panel burnout
C) Thermal runaway
D) Cell inversion
A) Photovoltaic degradation
What does PV Cell stand for?
Photovoltaic
What is a solar farm?
Large groups of solar panels typically in a wide open area
What is the non-renewable source harnessed and converted to give energy to houses and buildings in T&T?
Natural Gas. Bonus point if you can name the gas that makes up the largest percentage of natural gas.
Where does Solar Energy come from and how does solar panels work?
Solar energy comes from the sun, its works when Photon or light energy from the suns knocks electrons from the panel and causes them to flow.
What device would Ancient people use to harness Solar Energy?
Magnifying Glass
Photo _______ ________ make up this technology used to harvest the suns energy.
Voltaic Cells
The Sun is approximately 93 million miles away from Earth. This unit of measurement, equal to this distance, is commonly used in astronomy to describe astronomical distances.
A) Light-year
B) Parsecs
C) Astronomical Unit (AU)
D) Lunar distance
C) Astronomical Unit (AU)
What causes a flow of electrons to create energy in PV cells?
The action of electrons knocking other electrons loose and moving into other spaces for other electrons causes a of flow of energy.
This country is known for having the largest solar power capacity in the world, leading the way in solar energy adoption and production.
A) China
B) United States
C) Germany
D) India
A) China
When was Solar Energy first used AND for what purpose?
7th Century B.C. To light fires using magnifying glass
What role dose pv cells play in Solar panels?
helps absorb energy helping the solar panels generate it into electricity
What 4 different types of Renewable Energy?
Solar, wind, Hydropower, Geothermal, Hydroelectric, Hydrogen, Biomass
This device stores excess energy generated by solar panels for use during nighttime or cloudy days.
A) Inverter
B) Battery
C) Transformer
D) Capacitor
B) Battery
The process in which a solar panel converts sunlight directly into electricity is known as:
A) Solar thermal conversion
B) Concentration process
C) Photovoltaic effect
D) Heat exchange
C) Photovoltaic effect
What does Solar Energy reduce and why?
What are Greenhouse Gases, Sun light energy is used, not nonrenewable forms of energy that will pollute the environment.
Name 5 devices or technology that can incorporate or utilize solar power
Calculators, solar chargers, Solar powered vehicles, solar cooker, solar water heater, Solar watch.
What is the difference between Renewable and Non-Renewable Energy, with 2 examples of each?
Renewable energy harnesses natural energy to produce energy that we can consume. For example, wind's natural kinetic energy is used to turn a generator, which produces electricity. And since the wind will continue to blow, it cannot be "used up." Nonrenewable resources can only be used once, and we can't produce more to replace what we use eg Natural Gas & Oil.
Explain why an electric car is not always good for the environment. 2 reasons
Electricity Source: Charging EVs with electricity from fossil fuels can result in significant carbon emissions, potentially offsetting the benefits of driving an EV. Introducing Electrum
Battery Production: Manufacturing EV batteries is energy-intensive and creates more emissions than manufacturing internal combustion engine vehicles. Introducing Electrum
Mining Impact: Extracting materials like lithium for EV batteries can lead to habitat destruction, water pollution, and human rights concerns in mining communities.
Recycling Challenges: Recycling EV batteries is difficult due to their complex composition, leading to environmental hazards if not properly managed
