How Many Homes in the UK Have Solar Panels?

At a glance

The adoption of solar panels in the UK has grown significantly over the past decade as homeowners embrace renewable energy to reduce their carbon footprint and lower energy bills. According to recent data from the UK Government, over 1.6 million homes in the UK are equipped with solar panels.

That number represents around 4% of all households. The distribution of solar panel installations, however, varies widely across different regions due to factors such as sunlight availability, local government policies and economic conditions.

National Overview of Solar Panel Adoption

As of 2025, the UK has a cumulative installed solar capacity of approximately 15 GW. The majority of these installations are in England, with smaller but growing numbers in Scotland, Wales and Northern Ireland.

The adoption rate reflects not only the increasing affordability of solar technology but also a growing awareness of its environmental and financial benefits.

Regional Breakdown of Solar Panel Installations Across The UK

1. South East England

The South East leads the UK in residential solar panel installations. With its relatively high levels of sunlight compared to other regions, combined with strong local support for renewable energy initiatives, this region accounts for approximately 20% of the total residential solar installations. Popular counties such as Kent, Surrey and Hampshire are notable for their high adoption rates.

2. South West England

Known for its sunny climate, the South West is another hotspot for solar panels, contributing around 15% of the national total. Counties like Devon and Cornwall have embraced solar energy due to their favourable conditions and active local campaigns promoting renewable energy.

3. East of England

The East of England, encompassing areas such as Essex, Norfolk and Cambridgeshire, contributes around 12% of the UK’s solar installations. This region benefits from a good balance of sunlight and government incentives, making solar energy a popular choice for homeowners. Green Energy Electrical installs solar panels and battery storage systems across Essex and the East of England region – helping our area make the switch to renewable energy.

4. Midlands

The Midlands region accounts for approximately 18% of solar installations in the UK. Despite having less sunlight than southern regions, the area has seen significant growth in solar adoption due to proactive local government policies and energy savings programs.

5. Northern England

In Northern England, including Yorkshire and Lancashire, solar adoption rates are lower but steadily increasing. These areas collectively account for about 10% of the nation’s installations. 

6. Scotland

Scotland’s solar capacity accounts for approximately 6% of the UK’s total. While the country’s climate offers less sunlight, there is still a growing interest in solar panels, particularly in urban areas like Edinburgh and Glasgow. Scotland’s commitment to renewable energy has spurred growth in the sector.

7. Wales

Wales contributes around 5% to the national total, with solar installations growing steadily across the region. Rural areas in particular have adopted solar panels as part of broader efforts to integrate renewable energy into local communities.

8. Northern Ireland

Northern Ireland accounts for about 2% of the UK’s solar panel installations. While adoption rates are lower, interest is growing due to increasing energy costs and local government incentives.

The Road Ahead

As the UK continues to push towards its net-zero goals by 2050, solar panel adoption is expected to increase across all regions. Advances in solar technology, declining costs, and government support will likely bridge the gap between high- and low-adoption areas. Additionally, innovations in energy storage systems, such as battery storage, will make solar energy more accessible and reliable for homeowners nationwide.
