Understanding Solar Panels
Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electricity using semiconductor materials.
How Solar Panels Work
The process involves:
- Sunlight strikes photovoltaic cells.
- Electrical charges are generated.
- Direct current (DC) electricity is produced.
- An inverter converts DC into alternating current (AC).
- Electricity is supplied to the property.
Modern solar technology is highly efficient and capable of generating electricity even under cloudy conditions, making it well-suited to the UK climate. :contentReference[oaicite:1]{index=1}
