Solar energy has come a long way from being seen as niche or experimental. Today, it’s one of the fastest growing energy sources in the UK – helping homeowners reduce bills, improve energy independence and future proof their properties.
At SolarTherm UK, we’ve been designing and installing bespoke solar and battery systems since 2010 across Essex, Kent and the wider South East. In this guide, we break down 10 lesser known solar facts – backed by real world experience – to help you understand what solar can truly do.
Solar Power Is Now Among the Cheapest Energy Sources
It’s a common misconception that solar is expensive. While there is an upfront investment, the cost of solar PV has dropped significantly over the past decade. In many cases, generating your own electricity is now cheaper than buying it from the grid – especially with rising UK energy prices. For homeowners in Essex and Kent, this makes solar one of the most cost effective long term energy solutions available.
Solar Panels Can Last 25+ Years
Modern solar panels are built for longevity. Most systems come with performance warranties of 25 years or more and in reality, they often continue generating electricity well beyond that. As there are no moving parts, maintenance requirements are minimal. A well installed system will quietly produce energy for decades to come.
Solar Technology Dates Back to 1839
The science behind solar energy isn’t new. The photovoltaic effect – the principle that allows solar panels to generate electricity – was first discovered in 1839 by French physicist Alexandre-Edmond Becquerel. What’s changed is efficiency, affordability and scalability – making solar viable for everyday homes across the UK.
You Can Earn From Your Solar System
Solar doesn’t just save money – it can also generate it. With schemes like the Smart Export Guarantee (SEG), homeowners can get paid for exporting unused electricity back to the grid. When paired with battery storage, you can maximise how and when your energy is used or sold. At SolarTherm UK, we design systems to optimise both savings and returns – not just install panels.
Sunlight Reaches Earth in Just 8 Minutes
The energy powering your home travels around 93 million miles from the sun to Earth in approximately eight minutes. That’s an incredible reminder of just how powerful and abundant solar energy is – and why it remains one of the most reliable renewable sources available.
Solar Energy Isn’t Just Electricity
When people think of solar, they often think of solar panels generating electricity. But solar energy can also be used for heating. Solar thermal systems capture heat rather than light and are often used for hot water systems or large scale industrial applications.
You Don’t Always Need Complex Technology
Solar energy can be harnessed in simple ways too. For centuries, people have used reflective surfaces and clever design to capture and use heat from the sun. While modern PV systems are far more efficient, it shows that solar energy is fundamentally simple – and incredibly versatile.
Ancient Civilisations Used Solar Design
The Romans were early adopters of passive solar design. Buildings like bathhouses were constructed with large south facing windows to capture sunlight and retain heat. This same principle is still used today in energy efficient home design – combined with modern solar PV systems for even greater impact.
Solar Panel Efficiency Has Improved Dramatically
Early solar cells converted less than 1% of sunlight into electricity. Today’s domestic solar panels can achieve efficiencies of around 21-23%. This means more power from fewer panels – making solar viable for a wider range of UK homes, even with limited roof space.
The Right Installer Matters More Than You Think
While some schemes promote “group buying” to reduce upfront costs, the reality is that solar isn’t a one size fits all product. Every home has different energy usage, roof orientation and future needs (such as EV charging or battery storage). That’s why at SolarTherm UK, we design fully bespoke systems tailored to each property – ensuring maximum performance, not just minimum cost.

FAQs
Is solar worth it in the UK?
Yes. Even with the UK climate, solar panels generate significant electricity throughout the year. With rising energy prices, most homeowners see strong long-term savings.
Do solar panels work on cloudy days?
They do. Solar panels generate electricity from daylight—not just direct sunlight—so they still produce energy even in overcast conditions.
How many solar panels do I need?
This depends on your energy usage, roof size, and system goals. A typical UK home might need between 8–14 panels, but a tailored assessment is essential.
Should I get battery storage with solar panels?
In many cases, yes. Battery storage allows you to store excess energy and use it later, increasing your energy independence and reducing reliance on the grid.
How long does installation take?
Most residential solar installations are completed within 1 days, depending on system size and complexity.
