How Solar Panels Work
If you’re considering investing in solar panels for your home or business, it helps to understand how solar panels work and how they generate electricity.
A solar PV system works by converting sunlight directly into electrical energy. This process is known as the photovoltaic effect.
The Photovoltaic Effect
Solar panels are made up of photovoltaic (PV) cells, usually manufactured from silicon. When sunlight reaches these cells, energy from light particles causes electrons within the material to move. This movement of electrons creates an electrical current.
In simple terms: Sunlight → Electron movement → Electrical current.
There is no fuel, no combustion and no moving parts. Solar panels convert light directly into electricity.
It is normal to find a group of solar panels operating together within a given installation. This is called an ‘array’.
From Panel to Property
The electricity produced by a solar panel is direct current (DC). In a complete solar PV system, this flows to a solar inverter, where it is converted into alternating current (AC) for use within a home or commercial building.
The generated electricity can then:
– Be used within the property
– Reduce electricity purchased from the grid
– Be exported where appropriate
Electricity produced by solar panels can be used to power homes and commercial buildings.

Understanding how solar panels work is the first step in assessing whether a solar PV system is
suitable for your property.
