Just solar? Or solar and battery storage?


Solar panels and battery storage has soared in popularity over the last few years, largely due to the money households save on rising energy bills.

Around 970,000 UK households have solar panels installed. That is about 970,000 households saving money and reducing their reliance on the grid.

Make your money back

A home solar and battery system will soon pay for itself in as little as 4.1 years due to soaring electricity prices according to new data from the Carbon Brief.

The average payback period for solar panels in 2021 was 15 years or more! That’s a big difference and saving. These stats are based on the payback period for a £4,300 rooftop solar system, with a power capacity of 3kW.

In 2020, the average payback period was 16.7 years, but under the current price cap, this reduces to 11.1 years. When energy prices increase again, the payback period will get even shorter.

How long do solar panels last?

You can expect your panels to last for at least 25 years. What is more, solar panels don’t simply stop working after 25-30 years.

They will continue to produce electricity, however, at a lower rate due to panel degradation. Panels are designed and continue working way beyond their guarantee period.

When will I break even?

This is an important question when you are thinking about buying solar panels. Thankfully the time frame is getting shorter and you will break even faster. The exact answer depends on a number of factors including:

  • Where you live
  • How much your solar installation cost
  • Your energy usage, Price of electricity
  • If you have battery storage
  • If you are part of the Smart Export Guarantee scheme

Example: It would take a typical household in the UK with a 3.5kW solar panel system that costs £5,500, and 9+ years to recoup the costs of installing panels.
