When it comes to solar panel upgrades, it isn’t always easy to know whether it’s actually worth your money and time. Your old system might still be “working fine”, but that doesn’t always mean that it’s working as well as it could be. With solar tech moving as fast as AI and robots, panels that were cutting-edge 15 years ago are now simply the entry-level option.
At Entire Renewables, we understand this struggle, so we’ve written this blog to try and help you decide whether your panels could do with a little refresh, whether that’s a full-blown solar panel glow-up, or just a little TLC. Let’s dive into the signs that it might be time for an upgrade, what’s changed in solar tech, and what upgrading could mean for your home.
Panels Wear Down Over Time (Even If You Can’t See It)
Solar panels naturally lose a small % of efficiency every year. As temperatures rise and fall, the materials in your panels expand and contract, and years of UV exposure can slowly wear down their coating. None of this is a flaw; it’s just expected wear and tear, but after a decade or two, you’ll likely notice your output isn’t quite what it used to be.
That is why biannual cleaning and regular TLC are crucial. Removing bird droppings, tree sap, and debris from your panels can make a massive difference in getting the most from your solar panels for the longest time. Take a look at our maintenance blog to see if your solar panels are getting the love they deserve. Maintenance truly does matter!
Rising Energy Prices Make Every Upgrade Worth More
We guarantee you’ve noticed the insane surge in energy prices, and as they keep rising and growing more volatile, generating and storing your own power has become more valuable every year, with no signs of stopping. So it’s no surprise that over 172,000 new solar installations were fitted in the first half of 2026 alone as more people turn to greener energy to keep their running costs affordable. At Entire Renewables, our goal is to help people make greener choices, and seeing this solar growth has been amazing.
Many people also don’t realise that pairing solar with a battery system can help them to save even more on their energy bills. Our GivEnergy systems can actually sync with smart tariffs like Octopus Agile and Intelligent Octopus Flux, which automatically buy electricity when it’s cheap and use their own stored electricity instead of the grid when it’s expensive, so you save money without having to think about it or manage anything yourself. To put this into perspective, as a Flux customer you could save £100+ a year compared to the standard tariff!
What An Upgrade Actually Looks Like With Entire Renewables
If you’ve taken a look at our website, are thinking of upgrading, and are unsure which of our solar products would be the most beneficial upgrade for you, we’re here to help break them down for you:
SolarEdge: In older systems, all your panels are wired into one line (often called a string), meaning that if one panel is in the shade, covered by a tree, or not receiving as much sunlight, it drags down the output of the entire line.
With SolarEdge’s system, each panel works independently, so if one gets shaded, it affects only that panel. So if your roof is prone to a bit of shading throughout the day, SolarEdge could be the upgrade you’re looking for.
GivEnergy: GivEnergy battery systems automatically charge up when electricity is cheap and use that power instead of the grid when prices rise, ultimately saving you money with zero effort.
So, if you’re a homeowner who is already on, or wants to switch to, a smart electricity tariff and you want your system to work in the background without any input needed, GivEnergy could be your best bet.
Myenergi: Got an EV? The ‘Zappi’ charger is the world’s first solar-compatible EV charger, meaning you can charge your car before it even touches the grid. You can pair your ‘Zappi’ charger with a ‘Libbi’ battery storage (up to 20kWh and a 10-year warranty) as well as run your home and your car on energy you’ve already got stored.
