If you’re looking to reduce your carbon footprint and save on energy bills, installing solar panels in your home is a great option.

While many people choose to hire a professional to install solar panels, it is also possible to go down the DIY solar panels route and buy and install them yourself in the UK.

In this article, we will take a look at the steps involved in buying and installing solar panels yourself.

Step 1: Determine your energy needs

The first step in buying is to determine your energy needs.

This will help you determine how many solar panels you need to generate enough electricity to power your home.

You can do this by looking at your past energy bills and calculating your average energy usage.

Step 2: Choose a solar panel supplier

Once you have determined your energy needs, it’s time to choose a solar panel supplier.

There are many suppliers to choose from in the UK, so it’s important to do your research and choose a reputable company.

Look for a supplier that offers high-quality solar panels and provides good customer service.

Step 3: Purchase your solar panels

Once you have chosen a supplier, it’s time to purchase your solar panels.

Make sure you buy enough panels to generate the amount of electricity you need.

Don’t forget to buy essential accessories like a mounting system and an inverter. The inverter transforms the solar panels’ DC power into usable AC power for your home.

Step 4: Install your solar panels

Installing solar panels yourself can be a bit challenging, but it is possible. It’s important to follow the instructions provided by the manufacturer carefully.

Here are the basic steps involved in installing solar panels:

  • Install the mounting system: This is the frame that holds the solar panels in place. You will need to attach the mounting system to your roof or other structure.
  • Connect the panels: Once the mounting system is in place, you can connect the solar panels together using the provided connectors.
  • Install the inverter: The inverter should be installed close to your home’s main electrical panel. It will need to be wired into your electrical system.
  • Connect to the grid: Connect your solar panels to the inverter and then link the inverter to the grid, a task usually carried out by a licensed electrician – a highly recommended step.

Installing solar in the UK has its advantages and disadvantages when compared to hiring a professional company to do it.

Here are some of the pros and cons to consider:

Pros of DIY Solar:

  1. Cost: One of the main advantages of DIY Solar is cost savings. Hiring a professional installation company can be expensive, and doing it yourself can save you thousands of pounds.
  2. Learning experience: It can be a great learning experience. It can give you a better understanding of how solar panels work and how to maintain them.
  3. Control: You have complete control over the entire process. Select the specific solar panels you desire and oversee the installation to ensure it meets your satisfaction.

Cons of installing solar panels yourself:

  1. Safety concerns: Installing solar panels can be dangerous, especially if you don’t have experience working at heights. You could fall or injure yourself while working on your roof.
  2. Lack of warranty: If you install solar panels yourself, you may not receive the same warranty or guarantees that you would get from a professional installation company. This means that you may have to pay for any repairs or replacements out of pocket.
  3. Time-consuming: Solar can be time consuming, especially if you don’t have experience doing it. This could mean that you spend several weekends or even months completing the installation.
  4. Building regulations: In the UK, you must adhere to strict building regulations when installing solar panels. If you’re not familiar with these regulations, you may inadvertently violate them, which could result in costly fines or legal issues.

Installing solar panels on your home can significantly lower your electricity bills while also reducing your carbon footprint.

But is trying to install solar yourself a wise DIY project or best left to the professionals?

While the idea of solar DIY can seem attractive, there are many benefits to having solar panels installed correctly by qualified installers.

The positioning and placement of solar panels on your roof is crucial for collecting maximum sunlight.

Professionals use specialised tools and software to survey your home and strategically design a system for optimum efficiency.

Attempting the technical specifications and calculations yourself without solar training risks an inefficient system.

Professionals also have extensive experience fitting panels on a wide range of roof types from tiles to slates.

They know the quickest and most secure installation techniques to get your system up faster.

DIY mistakes like shoddy panel connections, damaged roofing or poor alignments mean the system won’t function as intended.

Solar installers are familiar with all the current regulations surrounding permits, building codes, utility requirements and safety standards.

If you DIY and overlook any of these rules, you risk compliance issues, fines, needing to re-do work or even voiding insurances due to unpermitted works.

Improper electrical connections can also pose safety hazards.

Solar rebates such as the Smart Export Guarantee require the system be installed by a certified professional to qualify.

DIY solar means missing out on thousands in guaranteed extra income over the system lifetime.

Professional certifications also unlock access to more competitive solar loans.

Leading installers provide guarantees ensuring your system will perform as expected, often producing a minimum amount of solar energy.

DIY systems won’t carry any such assurances. You take on all the risks of underperformance.

Workmanship and system defects will require you to cover repair costs rather than the installer.

From cleaning panels to dealing with inverter issues, solar systems require regular maintenance.

Installers include maintenance services so you get continued support long after installation.

You’ll handle all troubleshooting solo with DIY solar without any technical guidance.

For the significant investment in a solar system that you expect to rely on for decades, avoiding DIY risks and using qualified professionals who design, install, and back the system is strongly advised.

Paying more upfront for an expert job delivers superior ROI.
