Debunked: The Biggest Myths About Solar Panels in the UK

We bust the biggest myths about home solar systems in the UK, showing how modern solar panel installations and battery storage offer real savings and long-term value.

We bust the biggest myths about home solar systems in the UK, showing how modern solar panel installations and battery storage offer real savings and long-term value.

Are you considering installing solar panels for your home but unsure what to believe? You're not alone. With so many myths flying around, it’s no surprise homeowners across the UK are left wondering: Are solar panels cost-effective? Do they even work in our weather? Are they expensive to run?

Let’s clear things up once and for all.

Myth #1: Solar panels don’t work in the UK because it’s too cloudy

Here’s the truth: solar panels don’t need constant sunshine to work. They generate electricity from daylight – not just direct sunlight – which means they still produce energy even on cloudy or overcast days. In fact, Germany (which gets less sun than much of the UK) is one of the world leaders in solar adoption.

Myth #2: Solar panels are too expensive and won’t pay for themselves

Solar panel prices have dropped significantly in the past decade, and when you consider rising energy costs, solar panel savings can be substantial. Depending on where you live and your energy use, solar panels can save you between £395–£525 a year, according to the Energy Saving Trust. Over time, many homeowners find solar panels do pay for themselves, especially when paired with smart battery storage

Moreover, as technology advances, the efficiency of solar panels has improved remarkably. Modern monocrystalline panels now achieve efficiencies between 19% and 22%, a significant increase from the 15% efficiency common in 2010. This means you're getting more energy output from the same number of panels. At the same time, costs have continued to decline. For instance, the average cost of a 4kW solar panel system in the UK has decreased by approximately 16% since May 2023, now ranging from £5,000 to £6,000. 

Myth #3: They’re expensive to run and maintain

One of the best things about home solar systems is their low maintenance. With no moving parts, solar panels generally only require a light clean once or twice a year and a routine system check every few years. Most systems come with warranties of 20+ years, meaning you’ll benefit from long-term solar panel savings with minimal upkeep. So, no, solar panels are not expensive to run.

Myth #4: You can only save during the day

Not true. Solar panels paired with battery storage allow you to store excess energy generated during the day and use it at night. That means you’re not just saving when the sun’s out – you’re reducing your reliance on the grid 24/7.

An added benefit of battery storage is the ability to take advantage of time-of-use energy tariffs. With the right tariff, such as Octopus Energy's Intelligent Octopus Flux, you can charge your battery during off-peak hours when electricity prices are lower, typically overnight, and use that stored energy during peak times when rates are higher. This approach not only maximises your savings but also enhances your energy independence.
