Solar PV Calculator

The number of solar panels you need for your home in the UK will vary depending on a number of factors, including:

• Your energy consumption
• The size of your roof
• The efficiency of the solar panels you choose
• The amount of sunshine your roof receives

According to the Solar Trade Association, the average UK household needs around 10 solar panels to generate enough electricity to cover its annual needs. This is based on an average energy consumption of 2,900 kWh per year and an average efficiency of 15% for solar panels.

However, the exact number of solar panels you need will vary depending on your individual circumstances. For example, if you have a large house or a high energy consumption, you may need more panels.

To get a more accurate estimate of the number of solar panels you need, you can use a solar panel calculator. These calculators take into account all of the relevant factors to give you a personalised estimate.

Here are some additional things to keep in mind when calculating the number of solar panels you need:

• The orientation of your roof is important. South-facing roofs receive the most sunlight, so they are the best for solar panels however, East and West are a usable space when unshaded.
• Any shading on your roof will reduce the amount of electricity your solar panels can generate. Solar PV Optimisers will offset this problem.
• The type of solar panel you choose will also affect the number of panels you need. More efficient solar panels will generate more electricity per panel, so you will need fewer of them.

If you are unsure how many solar panels you need, it is best to consult with Mr Solar who have over 11 years experiance.
