The UK's solar sector is in the middle of an unprecedented surge. 2025 was the strongest year on record for solar deployment, as we saw 269,000 new installations completed across the country. It is the equivalent to a new rooftop solar installation every two minutes. In March 2026, the UK passed the two million solar installations for the first time and over the course of 2025, installed capacity grew by 13.6%. But this is only the beginning as the government targets call for a tripling of the solar capacity to around 60GW by 2030.
This rapid expansion puts real pressure on the workforce. Delivering millions more solar installations across homes and commercial buildings depends on a sustained increase in trained installers, electricians and engineers, and demand for those skills is rising faster than the pipeline of qualified people can keep up. For electricians and electrical contractors, this is a significant opportunity: adding solar PV installation to your skillset positions you at the centre of one of the UK's fastest-growing trades.
The question most electricians ask next is straightforward: which course actually gets you there? GTEC's Solar PV Training course is designed specifically for this purpose, taking experienced electrical operatives through everything they need to design, install, commission, and maintain domestic and commercial solar PV systems. Below, we break down why upskilling matters, what a good qualification should cover, and what it means for your business.
Why do qualified electricians need to upskill to fit solar panels?
A Level 3 electrotechnical qualification is a strong technical foundation, but it isn’t enough to install solar PV systems safely and competently. Solar PV installation introduces a distinct set of challenges that general electrical training doesn't cover in depth, including DC-side design and circuit work, panel and inverter selection, roof-mounting and structural considerations, site surveying, and system commissioning and fault-finding. Get any of these wrong and you're looking at underperforming systems, safety risks, or installations that fail to meet the standards required for certification.
This is where a dedicated, specialist qualification comes in. GTEC's course leads to an LCL Awards Level 3 Certificate in the Installation and Maintenance of Small-Scale Solar Photovoltaic Systems, a nationally recognised qualification built specifically around solar PV competence, rather than general electrical work. It's delivered over three days of practical, hands-on training using purpose-built solar PV rigs and live equipment in a fully functioning plant room, alongside theory covering health and safety, industry regulations, and best practice. Candidates finish with a practical observed assignment and an open-book theory assessment, giving employers and customers confidence that the installer in front of them genuinely understands the system they're fitting.
What makes a good solar panel installer qualification?
Not all solar training is created equal. A genuinely useful qualification needs to cover the full lifecycle of a solar PV project, from initial site survey and system design through to installation, commissioning, and ongoing maintenance and fault-finding. Anything narrower leaves gaps that show up the first time something goes wrong on site.
There are a few specific elements worth checking for
18th Edition Wiring Regulations.
All new electrical installations in the UK must comply with the 18th Edition of the IET Wiring Regulations (BS 7671:2018+A2:2022), and this qualification is one of the prerequisites for undertaking the full assessment on most solar PV courses, including GTEC's.
GTEC's 18th Edition Wiring Regulations course is a three-day classroom-based course leading to a City & Guilds Level 3 Certificate, and it's also required for operatives wishing to join schemes such as the ECS Card Scheme or Competent Person Schemes. If you don't already hold this, it should be your starting point before progressing to solar-specific training.
The Microgeneration Certification Scheme (MCS)
Most energy providers require an MCS-certified installation before customers can access the Smart Export Guarantee, which allows households to sell excess electricity back to the grid. Without MCS recognition, you're effectively locked out of a large share of the domestic solar market. Octopus Energy is currently the main exception to this rule. Installers can work under an MCS umbrella scheme, where a certified organisation handles the paperwork and commissioning, or pursue full MCS certification themselves by demonstrating competency and having a robust quality management system in place. A good course should be MCS-recognised and able to guide you through this next step.
LCL Level 3 certification
As covered above, this is the qualification that confirms solar-specific competence. To complete the full assessment, candidates typically need to already hold their 18th Edition certificate and a Level 3 electrotechnical qualification (or equivalent), making it the natural next step once those foundations are in place.
What are the benefits of qualifying to fit solar panels?
Adding a recognised solar PV qualification to your CV does more than open up a new service line; it changes the shape of your business. With rooftop solar accounting for the vast majority of new UK installations and demand showing no sign of slowing, electricians who can offer solar installation alongside their existing services are positioned to win work that non-specialist competitors simply can't quote for.
There's a commercial case here too. Customers increasingly expect their electrician to be able to handle the full job, including wiring, testing, and renewable upgrades, rather than coordinating multiple contractors. Holding an MCS-recognised qualification also means access to the Smart Export Guarantee market, which covers the large majority of domestic customers looking to install solar.
Beyond the immediate revenue opportunity, solar qualifications are a genuine investment in future-proofing your business. As the UK moves further into its net zero transition and government targets push capacity toward 60GW by 2030, demand for qualified installers will only continue to grow. Electricians who build these skills now are establishing themselves ahead of a market that's still expanding, rather than playing catch-up later.
If you're ready to add solar PV installation to your services, explore GTEC's solar PV installation training and take the next step toward a qualification that's recognised, practical, and built around what the industry actually needs.
