When it comes to renewable technology installation, many often wonder “Can I install solar panels myself?” Although you can, there are many downsides to DIY or "Do It Yourself" solar panel installation. That’s also where DIY kits come in, allowing buyers to install their own solar panels easily.
Let’s go over the pros, cons, and prominent models for solar panel DIY and DIY solar installation in the UK.
However, if you’re unsure about installing solar panels yourself, you’ll need to find a reliable installer. Hiring an experienced professional is both safer and less stressful but it’s all about hiring the right one. Finding one can be a difficult task that takes days of research, calling up companies, and comparing their offers. Thankfully, it doesn’t have to be such a chore.

Yes. It is possible to install solar panels yourself. It can be especially easy if you are installing ground-based mounts or if you buy a DIY kit. Installing on a roof can be more difficult, requiring lag bolts and decent drilling skills. Installing panels yourself can also come with potential downsides as many energy providers will not allow you to earn money for excess energy generation without an accredited installer and solar panel companies could cancel your warranty.
It is also best to attempt a DIY installation only if you are sure you know what you’re in for. Aside from the numerous technical issues that could arise, it can also be unsafe without the proper equipment, especially when installing solar panels on a roof.
On the other hand, it has also never been easier to install solar panels yourself. With the help of calculators and other online resources, you can easily determine how many solar panels you need. With a DIY kit, most of what you’ll need is measuring equipment, a good drill, and mostly the tools you’ll find in your toolbox.
That said, it can be a lot of work, especially if you’re looking to install off-grid solar panels, which can require precise placement and consistent power. Miscalculations could cause you to lose power or receive less than you need for your daily energy needs.
Long story short: While you can fit solar panels yourself, the affordability it provides also comes with the loss of warranties and DIY installations are not eligible for earnings from the Smart Export Guarantee (SEG), unless the panels you install are part of an MCS-registered DIY solar panel kit. A standard 3-bedroom house with a 4kW solar panel system could save between £440 to £660.
Yes, it is fully legal to install DIY solar panels in the UK on your own. In some areas, planning permission may be required but, in most regions, there are no laws against it. The rules may differ if you live in a conservation area so it’s best to check with local authorities.
As always, if you are living in a rental property, it’s important to get clearance from your landlord before you try to fit your own solar panels. Additionally, there may be building regulations for solar panels for apartments.
Overall, it’s less of a question of “Can you install your own solar panels?” and more about what you could lose by doing it yourself. As mentioned earlier, certain benefits from manufacturers and installers can be a good incentive to hire a professional. You will not be allowed to make money from exporting solar energy, for example.
There are a few points to consider before you go and self install solar panels.
Pros | Cons |
---|---|
Potentially decreased costs | SEG earnings won’t apply |
More control over the process | May void solar panel warranties |
Better for vehicles | Potentially causes sub-par installation |
No professional support |

A DIY solar system kit can be a favourable alternative to standard panels due to the ease of installation but, to be honest, they may not be worth it compared to a proper installation. DIY panel kits are often best for mobile homes and outdoor applications. They have utility for homes but can be less powerful, less efficient, and only barely less expensive when taking into account savings versus purchase costs.
If you are looking for solar panels we recommend looking over our list of the best solar panels. If you want the ease of use of a DIY kit, continue reading but also be aware of their drawbacks.
If you’re looking for the best deals on standard solar panels and their installation, we recommend checking out multiple installers before you make your decision. A good installer can provide A-grade service and swift installation at reasonable prices. Finding one can be tough (let alone finding multiple installers) which is why our service is a quicker alternative.

There are 2 main ways to install solar panels yourself: either with a kit or buying and building a system piecemeal. Kits are easier to install but piecemeal systems can be cheaper. Below, we’ll cover the steps for the latter method.
If you want to install your own solar panels, here’s a basic rundown of how:
We recommend parallel wiring but both have their benefits. Series wiring will allow for better voltage, less overheating, and additional cells to add to voltage. On the other hand, series wiring can lower your output since it defaults to the output of the weakest cell. Parallel wiring does not have this issue and is not hampered by shade and will continue to function despite inefficiencies in other panels. Although parallel can have lower efficiency, it will produce higher amperage.
While it’s completely legal and possible to install your own solar panels, it is best to have a professional installer do the job. You can lose out on a lot of benefits that only come with MCS or other accredited installers such as warranties and SEG earnings. This is especially crucial if you’re looking to make some extra money off of your solar installation.
Before installing your own solar panels, you should definitely check whether your roof and electric system are suitable for them. DIY solar power systems often have a high number of processes involved, so you will have to check which ones may be hazardous to your roof.
There are actually a lot of points we didn’t cover as they may relate to your specific home and energy situation. If all of this information seems overwhelming, you may want to consider hiring a professional installer.
The problem with installers is that you need to be sure you’re hiring a trustworthy one who provides great service and can help you navigate things like solar panel grants. While this can ordinarily take days of time-consuming research and contacting companies, we can streamline your search and provide you with multiple prices.
