Are Solar Panels Worth It? A 2025 Guide for UK Homeowners

With over 1.5 million UK homes now fitted with solar panels, it's clear that UK homeowners are looking for ways to combat rising energy costs and embrace renewable energy. Expert consumer sites like MoneySavingExpert.com regularly analyse the market, and the consensus is that a solar investment can be fantastic-but you need to understand the numbers behind your solar project first.

This guide will walk UK homeowners through the key costs and benefits of solar panels, explain the challenges of this clean energy source, and show you how to truly maximise the power from your solar investment.

The Costs vs. The Savings: What to Expect from Solar Panels

When considering solar panels, the first thing to weigh up is the initial investment in a solar panel system against the long-term savings on your energy.

  • Upfront Cost: According to the Energy Saving Trust, a typical solar panel system has an average cost of around £6,100. This price for new solar panels can vary depending on your location in the UK and the installer you choose for your solar setup.

  • Bill Savings: By using the electricity your panels generate, a typical household can save between £190 and £350 a year on their energy bills. This direct saving on your electricity bills is a major benefit of generating your own solar power.

  • Export Payments: Any solar electricity you generate but don't use is exported back to the grid. Through the Smart Export Guarantee (SEG) scheme, suppliers will pay you for this power, adding another income stream from your panels.

However, with a hefty initial cost for the panels, the break-even point for a solar system can be 10 years or more. For many UK homeowners, this is a long time to wait to recoup their solar investment.

The Hidden Challenge: Wasted Solar Energy

The biggest factor in how quickly you break even is how much of your self-generated solar power you actually use. As MoneySavingExpert rightly points out, "To max your savings, use most of your electricity while you're generating it."

This presents a fundamental problem for most households with solar panels:

  • Peak Generation: Your solar panels produce the most electricity and solar power in the middle of the day. This is when your solar generation is at its peak.

  • Peak Usage: Your household uses the most energy and electricity in the evening.

When you're out during the day, a huge amount of that free solar energy you've generated is sold back to the grid for a low price. Then, just hours later, you're forced to buy expensive electricity back from the grid to power your home. This means the full potential of your panels isn't being realised.

The Solution: Store Your Power with Solar Battery Storage

So, how do you use your solar power in the evening? You store it with battery storage.

A solar battery is the key to unlocking the full power of any solar panel system. It stores the excess solar energy and electricity your panels generate during the day. This stored energy can then be used to power your home for free throughout the evening and night.

By adding batteries to your solar system, you can:

  • Drastically cut your electricity bills by using your own stored solar energy instead of buying power from the grid.

  • Maximise your solar investment by using virtually all the power your solar panels generate.

  • Gain energy independence with a reliable source of renewable energy and clean energy.

The main consideration is the additional upfront cost for batteries. Finding a high-quality, reliable battery storage solution at the right price is essential to complement your solar panels.

"Installing solar is a great start but it’s only half the story. Without a battery you’re not getting the full ROI. We created Volta to fill the gap, so every homeowner can finally get the most out of their savings and be in control of their energy."
