Solar panels are an eco-friendly way to generate heat for homes, businesses and can even gain you money if excess energy is generated. The Government’s Smart Exposure Guarantee (SEG) is a scheme which pays households for the solar energy they generate which is not used by the house itself.

The SEG scheme means some energy suppliers need to offer tariffs which pay a set rate for each Kilowatt-hour (kWh) of electricity you export.

How much you can get is – like most household bills – dependent on which supplier you go for, and you can opt to look around to find the best rate for you.

Solar panels are an addition to your roof, but don’t usually need planning permission – there are a couple of exceptions, however – if your house has a flat roof, is in a conservation area or is listed.

You may need to get approval from your local council’s building control team, so it is best to check before proceeding.

How many Solar panels do you need to heat a house?

Solar panels are affixed to the roof and take in sunlight, converting it into usable energy.

The number of panels you would need to power your home depends on several factors such as

  • The size of your home
  • Your average daily energy consumption
  • The sun hours in your area
  • Your roof size advise 12 solar panels are needed for a 3kW solar installation, and 24 panels for a 6kW installation.

Your average energy consumption is important to consider when looking at installing solar panels, so you should look at the total Kilowatt-hours (kW) you use or plan to use in your home.

Sun hours in your area is an important factor, and varies across the UK, with the south typically seeing more sunlight than the North of England.

And of course, the number of panels you can install is dependent on the size of your roof, and whether your roof can support the weight of the panels.

To determine the size of the panels you need for your house, you need to know the following:

  • How much energy do solar panels with different capacities generate?
  • The capacity of your roof: how much space in square meters is available?
  • Dimensions of solar panels per size or brand

How much do solar panels cost?

Like the number of panels you may need, the cost of installing them will vary.

This is dependent on brand, size of panels and the number of panels you want to install.

The cost can range from £1,500 to £8,000 for solar panel system sizes from 1 kW to 4 kW.

Another added cost may be the installation of a solar battery storage system – which can store unused energy generated by the panels.

According to greenmatch, households which install solar panels with a battery storage use about 80 percent of the energy they generate while households without a battery storage use only 40 percent of the energy they generate.

While it may cost more in the short term, the system can save you thousands in the long run.
