1. How Do Solar Panels Work?
Explanation of Solar Panel Technology
Solar panels capture sunlight and convert it into electricity using photovoltaic (PV) cells. These cells are typically made of semiconductors like silicon. When sunlight hits the panel, it activates the PV cells, generating electrical charges and creating a flow of electricity. This process begins as photons, or particles of light, strike the solar cell, knocking electrons free from atoms within the semiconductor material.
How Solar Energy is Converted into Electricity
- Sunlight Activates the Panels: When sunlight falls on the solar panels, the energy from the light is absorbed by the PV cells in the panel.
- Generating Direct Current (DC): The absorbed energy creates electrical charges that move in response to an internal electrical field in the cell, generating an electric current called direct current (DC).
- Conversion to Alternating Current (AC): This DC electricity flows into an inverter, which converts it to alternating current (AC), the form of electricity commonly used in homes and businesses.
- Electricity Distribution: Finally, the AC current is fed through a metre and into your home’s consumer unit, ready to power your appliances.
The key technology that enables this conversion is the photovoltaic effect—a phenomenon where light photons hitting the semiconductor material result in the generation of an electromotive force.
Thanks to these advancements, solar panels can generate electricity even on cloudy days, making them a reliable source of renewable energy in various weather conditions.
2. Are Solar Panels a Worthwhile Investment?
Cost Analysis for Typical UK Homes
When considering solar panels, one of the first questions homeowners ask is about the initial cost.
