Last year there were 1.5 million solar panel installations in the UK. Our solar capacity is increasing by 5.9% year on year, so if you’re considering making the switch, you’re not alone!

In the drive toward energy independence, solar power is a clear front-runner. With energy prices constantly fluctuating, the idea of slashing electricity bills while reducing our carbon footprint is appealing. 

But one key question often surfaces: should you hire professional solar panel installers, or risk doing it yourself with a DIY solar kit?

On the surface, DIY might seem cheaper and more straightforward. But scratch the surface, and the risks, hidden costs and complexities become hard to ignore. Here’s a breakdown of what truly sets professional solar panel installers apart, and why going pro almost always pays off in the long run.

1. A Design That Actually Works

Solar panels aren’t one-size-fits-all. The unique energy needs of your home, the angle of the roof, sun exposure, and even local weather patterns all influence what system will work best.

DIY kits offer little to no room for customisation. This means you might end up with panels that underperform, or worse, waste money on a system that doesn’t meet your needs.

Professional solar panel installers like our team start with a detailed site survey and energy assessment. We factor in how your system will be used, roof structure, areas of shade and long-term goals. Then we design a bespoke system that maximises efficiency and savings. That means you're getting the right solution from the start.

2. Proper, Safe Installation

A solar panel installation isn’t just about bolting panels to a roof. It involves electrical wiring, mounting hardware, weatherproofing and integration with your home’s electrical system. Mistakes can cause electrical faults, leaks in your roof and even fires!

DIY kits often oversimplify such steps, leaving critical gaps in safety. The reality is that YouTube tutorials can’t replace someone with years of experience.

Certified solar panel installers like our team are trained in both roofing and electrical work. They follow industry best practices and adhere to UK regulations such as the Microgeneration Certification Scheme (MCS) and Part P of the Building Regulations. This means a safer, higher quality installation with fewer surprises down the line.

3. Enjoy Higher Quality Equipment

DIY kits often include low quality panels, inverters and mounting systems. These components may be less efficient, have shorter lifespans, or come with limited warranties.

Professional installers have access to commercial-grade solar technology. At Jem Energy, for example, we use Tier 1 solar panels and high-efficiency inverters from trusted manufacturers. They perform much better and last for decades.

4. Warranty Protection and Ongoing Support

DIY kits usually come with a basic product warranty, but that only covers the equipment, not the installation. If something goes wrong during or afterwards, you're on your own. And if a component fails, removing and replacing it could void the warranty entirely.

Professional installers typically offer a workmanship warranty (often 5–10 years) on top of the manufacturer’s warranties. This means you're protected on all fronts. Plus, reputable companies like Jem Energy offer post-installation support, annual checks and remote monitoring.

5. Connecting to the Grid

Connecting your system to the National Grid isn’t as simple as flipping a switch. It requires getting permissions, inspections, and compliance with regulations like G98/G99 standards in the UK.

Most DIY installers run into roadblocks when it’s time to notify their Distribution Network Operator (DNO) or apply for the Smart Export Guarantee (SEG). Without proper sign-off, your system may not be legal, or worse, it may not be connected at all.

Jem Energy ensures everything is compliant and ready to go, so you can start saving from day one.

6. Long-Term Savings

Professional installers often help with accessing finance, green energy grants, and energy tariffs. All of these are savings that DIY buyers might miss. For example, qualifying for SEG payments usually requires installation by an MCS-certified installer. You won’t have that chance if you go it alone.

Jem Energy can walk you through available incentives and help structure your investment to get the fastest ROI. 

7. Better Peace of Mind

Your peace of mind is always worth it. When you hire trained solar panel installers, you’re not gambling with your investment or your safety. You’re getting a solution that works, supported by experts who are accountable if anything goes wrong.

Solar power is a long-term investment , not just in energy, but in your home’s value and your carbon footprint. Trusting professionals ensures that investment is sound.
