Solar panels generate electricity during the day. They generate more electricity when the sun shines directly on the solar panels. Figure 1 shows PV generation in watts for a solar PV system on 11 July 2020, when it was sunny throughout the day and on 13 July when there was a mixture of sun and cloud.
Importantly, photovoltaic solar panels produce electricity in the form of direct current, meaning the electricity must pass through an inverter to transform it into alternating current - which is what is normally used in buildings, appliances, sockets, and light bulbs.
A solar PV system on the south coast of England for example will generate more electricity annual than one of a similar size, orientation and inclination in the north of Scotland. A solar PV system on the south coast of England for example will generate more electricity annually.
When the photons from the sunlight reach the surface, these electrons gain the ability to move, generating a flow that creates an electric current. Each cell generates a small amount of energy and a panel is usually made of between 36 and 72 photovoltaic cells. By connecting several panels together, a photovoltaic system is created.
A south facing solar PV system will tend to generate more around noon. The sun rises in the east and so east-facing PV panels will have maximum generation part-way through the morning. A west-facing array will tend to generate most electricity part-way through the afternoon as shown to the right.
