Solar panels harness sunlight to produce electricity, offering a sustainable energy solution.
How Do Solar Panels Work?
- Photovoltaic Effect: Solar panels generate electricity using the photovoltaic effect, where sunlight excites electrons in semiconductor materials.
- Components: Solar panels consist of solar cells, an inverter, and a mounting structure.
- Conversion Process: Solar panels convert sunlight into direct current (DC) electricity, which the inverter then converts to alternating current (AC).
Step-by-Step Process:
- Sunlight strikes the solar cells.
- The solar cells absorb photons, knocking electrons loose.
- Electron movement generates direct current.
- The inverter converts DC to AC for use in homes or businesses.
