Recently, PV panels have been the talk of the town in the UK due to rising energy prices and growing awareness of environmental concerns. But what’s the real deal with these panels? Are they truly a smart investment, or simply another passing trend?
On this page, we aim to cut through the noise for you so you can have a much clearer picture of what solar panels can offer.
Let’s get started so you can find out if PV panels are more than just some bright idea!
Overview: Advantages and disadvantages of solar energy systems
There are many benefits that come with solar photovoltaic systems. When you produce your own power, you reduce your reliance on the power companies and contribute to a cleaner environment. Solar panels can increase your home’s resale value, making it an attractive investment.
As with anything, there are some potential disadvantages to think about. The initial costs can be high and not every roof is ideally suitable for solar panels. Additionally, if you’re planning on moving, or have low electricity costs, the financial benefits may be less significant. Installation and maintenance challenges can also pose issues. In any case, these disadvantages can be overcome and we’ll outline some solutions below.
Overall, it’s important to weigh up the pros and cons of solar panels wisely before making your final decision. Below, we’ve included a table showcasing the pros and cons of PV panels:
Advantages of solar panels: Why going solar is usually worth it
#1: You have significant savings on your energy bills and you’re less affected by rising energy costs
According to Statista, solar panels are becoming one of the cheapest ways to produce electricity, which is why their use is increasing worldwide. In 2005, the world only had around five gigawatts of solar power.
By 2022, that number increased to 1.18 terawatts. In the same year, China alone, installed around 415 gigawatts of solar photovoltaics. Indubitably, solar has grown in the last few years and remains one of the most heavily funded renewable energy sources.
One of the most attractive benefits of PV panels is undoubtedly the financial benefit of saving on your energy bills. Here’s how it works: solar panels turn sunlight into electricity, meaning you can generate your own power right at home. The more electricity your panels produce, the less you need to buy from the grid.
With PV panels, the average UK household can save up to £1,300 a year on energy costs. If we look at this over time, those savings can really add up, especially with energy prices on the rise. In fact, after 11 years, a solar panel investment should be worthwhile, as most households break even, accordingly.
When looking at just the numbers, for many people, installing PV panels can reduce their energy bills by as much as 80%, and that’s quite a chunk if you think about it.
But the benefits don’t stop there.
When considering the pros of solar panels, it’s important to think about the long-term advantages. They’re not just saving you money today—they’re a smart investment for the future too.
#2: You have control over your power and you’re less reliant on utility companies
Another pro to keep in mind with solar panels is the freedom they give you over your electricity supply.
Instead of having to depend on the grid (that’s controlled by the utility companies), you can generate your own power directly from your rooftop. This means you’re no longer at the mercy of fluctuating energy prices or any unpredictable loss in power.
With solar panels, you become less reliant on the utility companies because you’re generating your own energy. Plus, if you have battery storage, it’s even more beneficial.
This is because battery storage gives you a way to save any extra energy your PV panels produce during the day so that you can use it at night or during a power outage. So if the grid goes down – or when you’re faced with less daytime hours during the winter months – you can rest assured that your lights will stay on and your appliances will be running.
With PV panels, you’re in control: you use the sun’s energy to power your home, store any extra energy and rely less on the power grid.
#3: You contribute to a greener planet for the future generations
When looking at the pros and cons of solar panels, you can’t look past one of the best advantages to using PV panels and that is helping make the planet greener for our future generations. Solar energy is renewable, so it doesn’t run out like fossil fuels.
When you make the switch to harness the power of solar, you limit the need for harmful fossil fuels. This, in turn, lowers greenhouse gas emissions, which slows down climate change. This will benefit your home and help your community by promoting a shift toward cleaner energy and slowing down the effects of climate change.
#4: With solar panels installed, your home’s value increases, and it can sell faster
Incredibly, there are pros that many may not realise. Installing panels doesn’t just save you money on energy bills. It can also increase the value of your home. When we look at all the benefits of PV panels, we can’t help but share Marco’s Story.
Homes with panels are oftentimes more attractive to potential buyers because they see the long-term savings and smaller environmental footprint that comes with solar energy. As mentioned, energy prices continue to rise, so a home with lower utility bills is a big draw.
Additionally, some buyers appreciate the idea of supporting renewable energy, making your solar-powered home even more worthwhile. This means if you ever do decide to sell, having PV panels could give you a competitive edge while contributing to a greener future.
#5: You maximise your savings by leveraging government grants
One of the great things about going solar in the UK is that you don’t have to cover the full cost of installation on your own.
The government offers solar panel grants and incentives that help lower the upfront cost, making it more affordable for homeowners and businesses to switch to solar energy. These financial supports can reduce the initial investment, making solar panels a smart option for many.
Here are some of the key grants and incentives available in the UK:
- Smart Export Guarantee (SEG): This program pays you for the excess electricity your solar panels produce and send back to the grid
- VAT Reduction: Homeowners can benefit from a reduced VAT rate of 0% for solar panel installation, which directly cuts down on the overall costs
These schemes can make solar panels much more affordable, so it’s worth checking if there are local incentives in your area as well.
For more information on grants, visit Gov.UK or your local government’s website.
By taking advantage of these incentives, you’ll significantly lower your installation costs and make the switch to solar even more appealing.
#6: You can turn excess solar energy into additional savings with Net Metering
If you live in a location that offers net metering, then you can save even more with solar panels.
When looking at the advantages of PV panels, net metering lets you send any extra electricity your panels produce to the grid, and in return, you get credit for it. This means when your panels aren’t generating power (at night or on cloudy days) you can use those credits to lower your utility bills.
#7: Solar panels require minimal maintenance and offer long-lasting durability
Another significant benefit of solar panels is how little maintenance they need.
When looking at the pros and cons of solar panels, it’s good to know that once installed, most panels can last up to 30 years. This gives you decades of reliable energy with minimal effort. They’re designed to handle all kinds of weather—rain, snow, and even hail—so you don’t have to worry about them being damaged easily.
Most panels come with long-term warranties that guarantee their performance, so if anything does go wrong, you’re covered (panels from Soly have guarantees of up to 25 years). Overall, solar panels are a set-it-and-forget-it investment, giving you peace of mind while they quietly work in the background.

#8: By adopting solar energy, you’re setting an example in your community
Going solar doesn’t just benefit you, it can also inspire those around you to make the switch too.
When looking at the pros of solar panels, we can’t help but think about the fact that people in your community will see the savings and the environmental benefits of your PV panels setup, they may be motivated to follow your lead. This ripple effect can lead to a collective reduction in energy demand, aiding in preventing blackouts and reducing the need for new power plants.
Disadvantages of solar panels: Reasons to think-twice before investing in solar energy
#1: Solar panels may not suit every roof
When we look at the possible cons of solar panels, unfortunately not every roof is perfect for them. The direction and angle of your roof can affect how well the panels work. If your roof is shaded by trees, buildings, or chimneys, it might not be able to get as much sunlight and be as effective.
Additionally, the condition and type of roof you have could make the install process a bit of a challenge. Sometimes, structural issues could translate to needing extra work or reinforcements.
Not sure if your home would be suited to a solar set-up? Soly is here to help! Using our advanced satellite technology, we can assess your roof’s suitability via a quick phone consultation and guide you through the process.
#2: Solar energy isn’t ideal if you’re planning to move soon
If you’re thinking of moving soon, solar panels might not be the best investment. The cost of installing them might not be fully recouped before you move, and not all buyers might see the value in them.
Some incentives for solar panels also require long-term ownership, so you might not benefit from them if you’re planning to relocate soon. Removing and reinstalling solar panels can also add additional costs.
This truly doesn’t have to be among the cons of solar panels and could be considered an advantage if you look at it with a fresh perspective: If you don’t plan on moving soon, you’ll benefit from the energy savings and potential increase in property value. If you do move, there are always benefits to be gained from your solar investment in the meantime.
#3: Low electricity costs can mean limited solar savings
If you already have low electricity costs, the savings from solar panels might not be as significant. In areas with lower utility rates, it could take longer to see a return on your investment. The amount you save depends on how much energy you use and produce.
We could easily convert this disadvantage of PV panels into something that reflects a positive gain: That’s because even with low electricity costs, it’s still beneficial to save on your energy bill and gain energy independence. Plus, any savings you make add up over time, and you’re contributing to a cleaner environment.
#4: High up-front costs can be a barrier without financing
When looking at the pros and cons of solar panels, the initial cost of solar panels can be a disadvantage. Inevitably, the cost is quite high. The average 3.5kW PV system solar installation cost is around £7000.
For a full solar PV system the cost includes the panels, installation, and permits. When added together, the solar installations for a solar batter and solar panels typically cost around £8200 – £9800.This might make it hard for some people to afford.
While prices have come down over the years, the upfront expense can still be viewed as a challenge.
To explore a breakdown of the costs, have a look at our UK Solar Panel Prices 2024 guide which offers more detailed information about the costs involved when it comes to installing solar panels.
Importantly, however, there’s hope when it comes to handling this cost barrier. To help with these costs, there are government grants, financial incentives, or loans, you can reduce the initial investment.
Additionally, Soly has financing options such as Ideal 4 Finance and our new option that allows you to pay a £500 deposit, with the rest due only after the system is installed and fully operational. This makes solar energy more accessible for all.
#5: Solar panels don’t generate power at night
When looking at potential solar energy disadvantages, they do need daylight to generate power and can’t produce electricity at night.
Despite this, a solar energy system can still produce electricity year round. The panels will work, even on cloudy days and in winter. This ensures you’re still benefiting from solar energy, even though they don’t generate power at night.
Take it a step further and combine your solar panel system with a solar battery. This is a form of solar energy storage and will allow you to store that surplus energy generated during the day for use when the sun goes down.
#6: Some solar panels contain toxic materials
When looking at potential drawbacks to PV panels, there are some panels that use materials like cadmium or lead, which can be harmful during manufacturing and disposal.
This is why it’s important to choose panels made from safer, environmentally-friendly materials and check for certifications and recycling programs to manage these risks.
Despite these concerns, the overall environmental benefits of using solar panels—such as reducing your carbon footprint—far outweigh the impacts from their production. Solar panels help reduce CO2 emissions and contribute positively to the environment.
In fact, if you look at our guide: “How Much CO2 Emissions Can Be Saved With Solar Panels“, you can get a better idea of the CO2 savings while factoring in panel production.
#7: Solar panel installation can be difficult
Looking at the cons, installing solar panels can be quite complex. It can be a complex process that requires specialised labour and equipment.
In any case, installing a solar system it yourself can be challenging and risky. Roof space could be an issue for some homes and businesses.
To make things easier, hire professional installers. This way, you can avoid any unnecessary stress and ensure a smooth installation process.
Finding reliable solar installers can also be challenging
The quality of solar panel installation can vary widely. It’s essential to research and review potential installers to find reputable ones. Check their credentials, certifications, and insurance, and compare quotes to ensure fair pricing and reliable service.
