What is a solar panel payback period?

A solar panel payback period is the length of time it takes for the savings on electricity bills to equal the initial investment made in a solar energy system. Before we delve into the payback periods of solar panels, let's discuss how much you could expect to pay for a solar panel system in the UK.

How long do solar panels last in the UK?

Domestic solar panel systems in the UK typically have payback periods ranging from 5 to 7 years, though, as we've already covered, this can be shorter or longer depending on multiple factors. Commercial solar installations can see payback periods as short as 1 to 3 years, sometimes even less for larger systems.

How much does it cost to install solar power?

Installing solar power requires an initial investment in hardware and labour for the installation. The most expensive item will be the solar panels themselves. According to the latest government data, solar panels in the UK cost £6,000 to provide rough power for the average household.

How long does it take to recoup solar panels?

If we proceed to calculate the solar panel payback time based on these figures, we come to the conclusion it would take 9 years to recoup the costs. Now, let’s consider a system size of 5.2 kWp with battery included, also in Glasgow:

How do I register a solar PV system?

If you’re planning to install a solar PV system in your home, you must register it with your Distribution Network Operator (DNO). The DNO is the company responsible for bringing electricity to your home. Usually, your installer will register the device for you.

How much does a solar panel system cost?

Solar electricity is low carbon, renewable energy. A typical home solar panel system could save around one tonne of carbon per year, depending on where you live in the UK. That’s the equivalent of driving 3,600 miles, or from London to Bristol 30 times. The average domestic solar panel system is 3.5kWp and costs around £7,000.
