Embracing solar power is a proactive step homeowners can take in response to climate change concerns. As solar energy emerges as a favoured sustainable choice, many investment options can be overwhelming.

This naturally leads to the question: Do solar panels truly offer homeowners tangible financial savings? But before we get to that, let’s see how much investment is needed to install a solar panel.

How Much Are Solar Panels?

Solar panels are gaining traction in the UK for their affordability and efficiency. Prices range from £5,000 to £11,000, depending on the system size and other factors. In 2023, a typical 250W solar panel costs between £400 and £500. However, the total expense hinges on the system’s overall type and scale.

For homes, a 4kW system, costing around £6,400, is widespread. It occupies about 29 square metres of roof space. Thanks to advancements in technology, solar panel prices have significantly dropped.

While a system’s initial cost rises with its electricity generation capacity, the long-term savings grow proportionally. For example, a 3kW system might be more affordable upfront, but a 6kW system will yield more significant savings over 25 years.

Additionally, since April 2022, the UK Government’s temporary VAT exemption on energy-efficient measures offers further savings.

How Solar Panels Save You Money

The UK government offers solar panel grants to support individuals in their solar ventures. Introduced in 2010, the Feed-in tariff rewards homeowners for generating renewable energy. Payments vary based on the size of the installed solar system. There are two main tariffs:

  • Generation Tariff: Paid per Kw, based on the solar system’s size. You earn for both the electricity you generate and the amount you export back to the grid, as well as for the renewable energy you consume.
  • Export Tariff: Also paid per Kw, it offers a fixed rate for each unit of electricity you export to the grid, allowing you to sell unused electricity.

A solar photovoltaic (PV) system costs between £4,000 and £6,500, potentially saving over 1,200 kg of carbon emissions. The Feed-in Tariff can yield returns between £500 and £1,000.

While initial costs may seem steep, the Feed-in Tariffs ensure long-term savings and significant carbon emission reductions. As living costs rise, solar energy offers a hedge against increasing electricity prices.

With decreasing solar panel costs and the potential for increased home value, solar energy is both an environmentally and economically sound investment.


Solar panels offer a quick return on investment, leading to savings and other benefits like increased property value, reduced utility bills, and federal tax credits that mitigate installation costs.

Impressively, some solar panels achieve a 22% energy conversion rate, which can significantly reduce monthly electricity expenses. These panels consist of solar cells, typically made from semiconductors like silicon. When light hits these cells, they produce electricity, which ceases once the light source is removed.

With energy prices expected to remain high, solar energy emerges as a smart, cost-effective choice that also reduces your environmental impact. For a precise solar panel quote, visit the ECOfootprint website.
