The UK solar energy landscape is constantly witnessing significant changes driven by regulatory reforms, technological advancements, and ambitious industry targets.

As part of our new monthly “Latest Developments” blog series, here is an in-depth look at the latest developments shaping the sector as of June 2024:

Latest Developments in Solar 2024

Record-Breaking Growth in Solar Capacity

The UK’s solar capacity has achieved a new milestone, reaching 15.7 GW across 1,454,607 installations by January 2024. This represents a 6.6% increase from January 2023, highlighting the robust growth of the sector. The surge in installations is largely attributed to the increasing number of domestic solar systems, reflecting widespread adoption among homeowners.

Streamlined Regulations for Solar Installations

The UK government has introduced significant changes to planning regulations, making it easier for homeowners and businesses to install rooftop solar panels. These changes include the removal of planning permission requirements for solar installations on flat roofs and the elimination of the 1 MW restriction for industrial rooftop solar systems. This regulatory easing is designed to accelerate solar adoption, reduce installation costs, and help the UK meet its net-zero emissions targets
