Thinking about going solar? Whether you’re a homeowner looking to cut energy bills or a business owner aiming for a greener footprint, understanding the solar panel installation process is the first step.
In this guide, we break down how solar panels are installed, what it means for your property, and what you can expect at every stage – from your initial quote to switching on your fully fitted solar panel system.
We’ll also cover solar panel installation costs, financing options, and why choosing the right solar panel installers in the UK matters more than ever. So if you’re ready to explore renewable energy with a trusted partner, this guide is built for you.

Installing solar panels involves a carefully planned process that ensures your system is safe, efficient, and tailored to your property. Here’s a step-by-step guide to the solar PV installation process used by accredited solar panel installers in the UK.
Every solar panel installation begins with a detailed site assessment. An accredited installer will inspect your roof’s size, condition, pitch, and orientation to make sure it’s suitable for a solar panel fitting. They’ll also check for shading from trees or buildings that could reduce efficiency.
Key checks include:
Once your property is approved, the installer will design a custom solar panel system based on your energy needs and roof layout. This includes:
You’ll receive a full breakdown of what’s included in the system, expected energy output, and estimated savings.
On the day of installation, scaffolding is constructed to safely access the roof. Next, the installer fits the mounting system, which is securely attached to your roof tiles or joists.
Then, the solar panels are installed on the roof, clipped into place on the mounts, and wired together either in series or parallel, depending on the system design.
Most solar panel installations in the UK are completed in 2–3 days for residential properties.
The inverter is installed inside your home or business (typically in a loft, utility room, or garage). It converts the DC electricity generated by your panels into usable AC electricity.
If you’ve chosen to include a solar battery, it will also be connected at this stage to store excess energy for use in the evenings or during power outages.
Once your system is installed, it’s connected to the national grid. Your installer will complete all necessary safety checks and system tests, and apply for G99 approval with your Distribution Network Operator (DNO) – a requirement for grid-tied solar systems.
You’ll then receive:
After installation, you’ll be shown how to monitor your solar panel system’s performance, either through a digital app or an inverter display.
The best solar panel installers in the UK offer ongoing support and optional maintenance packages to keep your system performing at its best. Routine cleaning and annual inspections are the usual recommendations.
Solar panel installations are a perfect choice for many properties in the UK. Ideally, your roof should be south-facing, unshaded, and pitched at 30°, though east- and west-facing roofs can still perform well.
Tiled, slate, and even flat roofs can support a solar panel system, provided there’s enough structural integrity and space. During a site survey, installers will assess roof angle, size, shading from trees or buildings, and overall condition to ensure your setup will be safe and effective.
Even if your roof isn’t perfect, modern solar panel technology and expert design can still make it a smart option. A professional installer can confirm suitability and provide a custom quote tailored to your property.
A solar PV installation can cost anywhere between £6,000 and £15,000 in the UK. This entirely depends on things like:
Still have questions about the solar PV installation process? Check some of the most common ones below:
How long does it take to install solar panels?
Most standard residential solar panel installations take 2 to 3 days to complete. Larger or more complex systems, such as commercial or battery-integrated setups, may take slightly longer.
Do I need planning permission for solar panels?
In most cases, no. Solar panels are considered permitted development in the UK, so you typically don’t need planning permission. However, exceptions apply if your property is listed, in a conservation area, or part of a flat or shared building. Your installer will confirm this during the survey stage.
Can I install solar panels on a flat roof?
Yes, you can install solar panels on a flat roof using tilted mounting frames. These angled supports help maximise sunlight exposure and ensure proper water drainage. While flat roof installations can be slightly more complex, they’re a common and effective option – especially for commercial buildings.
Will solar panels damage my roof?
No, solar panels won’t damage your roof when installed by a qualified professional. In fact, they often protect the roof beneath from weathering. Installers use secure mounting systems that are designed not to compromise the structure or waterproofing of your roof. Pre-installation checks ensure everything is safe and suitable.
What are the benefits of solar energy?
Solar energy comes with a whole range of benefits, including:
What are the main types of solar panels?
There are three primary types of solar panels used in the UK, each with unique benefits:
