Solar energy, often called solar power, is the incredible force we tap into from sunlight. Through a phenomenon called the photovoltaic effect (every day’s a school day), we can transform the sun’s rays into electricity. It can power everything from your telly to your fridge, lights, and all your favourite appliances.
And in association with solar experts egg, we’re giving away one solar panel system worth £4,500! The lucky winner of our prize draw will not only get the system, they’ll also get free consultation and installation from egg – and they’ll be saving money long into the future too.
The prize draw is open until 30 April 2025 to current O2 customers who are UK residents age 18+ and are homeowners. Terms and exclusions apply – see below.
That’s right – while you’re probably already aware of renewable energy’s many environmental benefits, people don’t talk as much about the everyday financial benefits of clean energy. Better yet, installing solar panels is more accessible than ever.
With energy prices increasing, there’s never been a better time to consider adding solar panels to your home. The experts at egg have been powering the change to green energy for its customers for more than 10 years, helping people from all walks of life to make greener choices with its award-winning products like solar panels, battery storage and electric vehicle charging solutions.
With summer on the way, and the price of solar declining by around 90% since 2010, there’s never been a better time to switch. And if you’re not lucky enough to win the prize, as an extra helping hand, as an O2 customer you can now claim a £500 discount when you sign up for egg’s solar solutions through this link. Just another way of making stress-free solar a reality. Redemption mechanic, eligibility and terms apply (see below for details).
Armed with the right information, you can decide if solar energy is the right choice for your home. So, how else can renewable energy save you money? Here are three financial benefits of installing solar panels:

Installing solar panels means generating your own energy, saving it for later with battery storage, or selling the leftover energy by sending it back to the national grid. With just 6 solar panels, you could generate up to 2,848 kWh each year. This could save you between £140 and £3401 a year off bills at current Energy Price Cap rates. Obviously, it varies based on factors like location, energy usage and system size. That’s money you can put towards the things that truly matter to you.
But what about the burning question: how long until I start seeing those savings? Patience is key. It typically takes a few years to recoup your initial investment, but after that, it’s smooth sailing to the land of savings. Just think of it as a long-term commitment to both your wallet and the environment.
A smart way to maximise the return on investment is a home battery that stores any extra solar energy you generate so that you can use it later – even after the sun goes down. Perfect for these summer months on the way.
Did you know homes with solar panels are valued 6.1%-7.1% higher than those without? A study by Swansea University2 found that, on average, a house with solar panels could sell for £14,062 to £16,368 more than a house without.
The government, private energy companies and non-profit organisations are all gearing up for a fossil-free future which makes solar panels a desirable feature for many home buyers. The peace of mind of knowing that you aren’t reliant on the grid is often a sought-after selling point for potential homeowners.

With such a push for transitioning to green energy, the UK government is incentivising people to make the switch to solar. One such scheme is the Smart Export Guarantee (SEG), a government-backed scheme that pays households and businesses for the excess solar electricity they export to the grid.
UK residents can also claim reduced VAT for energy-saving products such as solar panels for up to 5 years. The UK government’s decision to scrap VAT on solar panels and other renewable energy technologies will save a typical family with rooftop solar panels more than £1,000 on installation and £300 annually on their energy bills.3
These are just the financial benefits of installing solar panels in your home. When it comes to the environment, a solar system will reduce your reliance on oil and gas, which will reduce your home’s carbon footprint. 4
