The average one-bedroom house needs six solar panels, a typical three-bedroom house requires 10 panels, and a five-bedroom house will usually need 14 panels. In each case, the panels will produce enough power to cover 49% of the average household’s annual electricity usage – or more, if you don’t leave the house very often.
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.
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.
Solar panels usually have an area of 1.3-1.7m², with 1.6m being the most common size. To calculate the required roof space: Multiply the number of solar panels by the average panel size in square meters. Compare the resulting area against your available roof space. For example, using the solar panels calculation from the previous section:
As a rule of thumb across the UK, your solar array will produce 760 kWh for every 1 kW of panels on your roof. Here’s a general idea of how much space different sized solar panel systems take up (in square metres – m2): *based of the average solar panel size of two square metres.
Additionally, while most homes in the UK meet the requirements for solar panels, there are still certain criteria you need to meet to maximise solar panel efficiency: A south-facing roof will deliver optimal results, while east-to-west-facing ones can lose about 15% energy efficiency. The level of shading in your surroundings.
