What Are Solar Panels?
Solar panels are devices installed on a roof or suitable surface that convert sunlight into electricity.
They work using photovoltaic (PV) cells, which create electrical energy when exposed to sunlight.
A typical home solar system includes:
Solar panels
Inverter
Mounting equipment
Electrical connections
Monitoring system
Optional battery storage
The panels produce direct current (DC) electricity, which the inverter converts into alternating current (AC) electricity that your home can use.
Any unused electricity can often be stored in a battery or exported back to the grid depending on your setup.
How Do Solar Panels Work in the UK?
A common misconception is that solar panels only work in countries with constant sunshine.
This isn't true.
Solar panels generate electricity from daylight, not just bright sunshine.
Even on cloudy UK days, panels can still produce energy, although output is usually lower compared with sunny conditions.
A solar system's performance depends on:
Roof direction
Roof angle
Shading
Panel efficiency
Weather conditions
System size
