What is Solar energy
What is the primary source of energy that solar panel convert into electricity?
What is sunlight?
These devices are made of semiconductor materials that convert sunlight into electricity.
What are solar cells?
This process, which occurs in the sun's core, generates the energy that we harness as solar power.
What is nuclear fusion
The production of solar panels can release this harmful substance into the environment, often associated with mining and manufacturing.
What is cadmium?
One of the most significant benefits of solar energy is that it produces this type of emissions during operation, contributing to cleaner air.
What are no greenhouse gas emissions?
This is a type of solar energy system is designed to provide heating for water or indoor spaces.
What is sunlight?
The two main layers of a solar cell include the n-type and this type of semiconductor layer, which captures positive charges.
What is the p-type semiconductor?
Solar energy was first utilized by heating water in this simple device, commonly found on rooftops.
What is a solar water heater?
Solar farms can disrupt local ecosystems and habitats, particularly affecting these types of animals that rely on specific land conditions.
What are native species
Solar energy systems can significantly reduce these costs for homeowners and businesses, particularly over time as technology improves.
What are electricity bills?
The process by which solar cells convert sunlight directly into electricity is known as this effect.
What is the photovoltaic effect?
This term describes the measure of how effectively a solar panel converts sunlight into usable electricity, usually expressed as a percentage.
What is solar efficiency?
In 1954, this company developed the first practical silicon solar cell, marking a significant advancement in solar energy technology.
What is Bell Labs?
The disposal of solar panels at the end of their life cycle can contribute to this type of environmental problem, if not managed properly.
What is electronic waste (e-waste)?
Solar energy contributes to job creation in various sectors, including installation and maintenance, leading to growth in this part of the economy.
What is the renewable energy sector?
This international organization, focused on renewable energy, is headquartered in Vienna, Austria, and publishes reports on global solar energy trends.
What is the International Renewable Energy Agency (IRENA)?
In a photovoltaic system, this device is responsible for converting direct current (DC) electricity from solar panels into alternating current (AC) electricity used in homes.
What is an inverter?
This type of solar technology captures sunlight to create heat, which can then be used to produce electricity or for direct heating.
What is concentrating solar power (CSP)?
This issue arises when solar panels are installed in regions that experience significant shading, leading to reduced energy output and inefficient operation.
What is shading effect?
By harnessing solar energy, communities can enhance their energy independence and reduce reliance on these fossil fuels that contribute to climate change.
What are fossil fuels?
This country led the world in solar energy capacity in 2020, surpassing 250 gigawatts of installed solar power.
What is China?
This phenomenon occurs when photons from sunlight knock electrons loose from atoms in a solar cell, creating an electric current.
What is the photovoltaic effect?
Before the widespread use of solar photovoltaic systems, this ancient method used the sun's energy to cook food by focusing sunlight through transparent materials.
What is a solar oven?
The manufacturing of solar panels requires significant quantities of this resource, potentially leading to water scarcity in areas where water is already limited.
What is water
This major environmental benefit of solar energy helps preserve natural resources by reducing the need for these traditional energy extraction methods that can cause habitat destruction.
What is reducing mining and drilling activities?
