As of June 2024, 5% of UK homes are powered by solar panels. In fact, that’s around 1.4 million homes! This is an astounding jump from 3.5% just two years ago and it shows us how more people are turning to solar to reduce their electricity bills and reduce their carbon footprint.
In this chart’s estimates the solar panel’s output used is 350W, which is the standard for many high efficiency panels. Although these numbers provide a helpful guide, remember that they are general estimates. The exact number for your home’s energy requirements may differ. More on that later.
The most common type of solar panel system used for domestic homes is PV – photovoltaic – panels. They collect energy from the sun in photovoltaic cells, which is then passed through an inverter to generate electricity. Each photovoltaic cell is made up of a series of layers of conductive material.
Most home panels can each produce between 250 and 400 Watts per hour. According to the Renewable Energy Hub, domestic solar panel systems usually range in size from around to 1 kW to 5 kW. Allowing for some cloudier days, and some lost power, a 5 kW system can generally produce around 4,500 kWh per year.
If you’re wondering how many panels are needed for a 5kW solar system, then the answer is between 8 – 13 panels, (either 350W or 450W). This, however, is only an estimate on paper, a home running only on solar power may need an even more powerful system to compensate for weather disruptions, family growth or property expansions.
