What are solar panels?
Solar panels are devices that convert sunlight into electricity. They are an essential component of solar energy systems, allowing energy from the sun to be harnessed for use in residential, commercial, and industrial applications.
How do solar panels work?
Solar panels consist of photovoltaic (PV) cells that capture sunlight. These cells generate direct current (DC) electricity, which is then converted into alternating current (AC) electricity by an inverter for use in homes and businesses. Here's a simple breakdown of the process:
- The sun emits photons that strike the solar panels.
- Photovoltaic cells absorb these photons, generating an electric current.
- The inverter converts the DC electricity to AC electricity.
- The electricity is used to power your home or can be fed back into the grid.
Types of solar panels
Choosing the right type of solar panel is crucial for maximizing efficiency and meeting your specific energy needs. Here are the main types of solar panels:
| Type | Description | Efficiency |
|---|---|---|
| Monocrystalline | Made from a single crystal structure, they are highly efficient and space-saving. | 15-22% |
| Polycrystalline | Made from multiple crystal structures; they are less efficient than monocrystalline but generally more affordable. | 13-16% |
| Thin-film | Flexible and lightweight, they can be integrated into various surfaces but have lower efficiency. | 10-12% |
