All Flashcards
What are the steps of electricity generation using solar panels?
- Sunlight strikes PV cells. 2. Electrons are knocked loose. 3. Electrons flow through a circuit. 4. Electricity is produced.
Define solar energy.
Renewable energy derived directly from the sun.
What are photovoltaic (PV) cells?
Cells that convert sunlight directly into electricity.
Define the photovoltaic effect.
The process where sunlight hitting PV cells knocks electrons loose, creating an electrical current.
Define renewable energy source.
An energy source that is naturally replenished and sustainable.
What are semiconductors?
Materials with electrical conductivity between conductors and insulators, used in PV cells.
How does using solar energy promote sustainability?
Reduces reliance on finite fossil fuels, lowers carbon emissions, and promotes energy independence.
How can government incentives promote solar energy?
Tax credits, subsidies, and rebates can lower the initial cost of solar panel installation.
