Solar Energy Surge: How the World's Cheapest Power Source Is Transforming the Electrical Industry
Solar energy has officially become the cheapest source of electricity generation in many parts of the world. For the electrical industry, this represents both a transformation and an opportunity.
The Numbers Tell the Story
Global installed solar capacity surpassed 1.5 terawatts in 2024, more than doubling since 2020. In the UK, solar generation continues to grow year on year, supported by falling panel costs and government incentives. Lithium-ion battery costs have fallen dramatically over the past decade, making solar-plus-storage systems increasingly viable for residential and commercial customers.
What This Means for Electricians
Every solar panel installation requires a qualified electrician. From roof-mounted residential systems to large-scale commercial arrays, the electrical work demands specific competence in DC systems, inverter technology, and grid connection requirements.
The Skills Gap
The supply of qualified solar installers is not keeping pace with demand. Training takes time, and many established electricians have not yet added solar PV skills to their portfolio. This creates a premium for those who hold the relevant qualifications.
Getting Qualified
The City & Guilds 2922 qualification covers everything needed for solar PV installation, from system design through to commissioning and MCS registration. Combined with the 2923 battery storage qualification, electricians can offer complete renewable energy solutions.
The Future
Industry projections suggest solar capacity will continue to grow rapidly. For electricians, investing in solar skills now positions them at the forefront of the energy transition with strong demand for decades to come.
