How do solar panels work?
These remarkable devices allow us to convert sunlight directly into electricity, providing a clean and renewable power source for our homes and businesses. Let’s take a closer look at how solar panels, specifically solar photovoltaic panels (PV panels), work their magic.
Solar photovoltaic panels (PV panels)
Solar photovoltaic panels are the most common type of solar panels used for generating electricity. They consist of several interconnected solar cells made from semiconducting materials, usually silicon. These cells convert sunlight into electrical energy through the photovoltaic effect.
To visualise the process, here’s a simple table summarising the steps involved in converting sunlight into electricity using solar panels:
| Step | Description |
|---|---|
| 1. Absorption of Sunlight | Solar cells absorb photons from sunlight. |
| 2. Generation of Electric Field | Photons transfer energy to electrons, creating an electric field. |
| 3. Separation of Charge | Electrons and “holes” are separated by the electric field. |
| 4. Collection of Electrons | Electrons are collected by metal conductive plates. |
| 5. DC Conversion | Direct current (DC) electricity is produced. |
| 6. Inverter Conversion | DC electricity is converted to alternating current (AC). |
| 7. Energy Consumption or Grid Connection | Electricity powers appliances or is fed back into the grid. |
- Absorption of Sunlight: When sunlight hits the solar panel, the cells absorb the photons (particles of light) present in the sunlight.
- Generation of Electric Field: The absorbed photons transfer their energy to electrons in the semiconducting material, allowing them to break free from their atomic bonds and create a flow of electric charge.
- Separation of Charge: The electric field within the solar cells separates the freed electrons from the positively charged “holes” left behind, creating a voltage potential across the cell.
- Collection of Electrons: The freed electrons are directed by the built-in electric field towards conductive metal plates on the surface of the solar cells. These metal plates collect the electrons, creating an electric current.
- Direct Current (DC) Conversion: Collected current is in the form of direct current (DC), the same type of electricity that batteries produce.
- Inverter Conversion: Since most household appliances and the power grid operate on alternating current (AC), the DC electricity produced by the solar panels is converted into AC by an inverter. This allows for seamless integration with the existing electrical systems.
- Energy Consumption or Grid Connection: The numerous electrical appliances in your home or business premises can then be powered by converted AC electricity. Suppose the solar panel system generates more electricity than you need. In that case, the excess power can be fed back into the grid, often earning you credits or compensation from your energy provider.
