It is abundantly clear that, where appropriate, solar panels can put unused roof space to good use and are an important technology in helping to reduce carbon emissions so I was pleased when the previous Conservative Government committed to widespread deployment of rooftop solar. Indeed, 99 per cent of all rooftop solar has been installed under a Conservative-led government.
Our ambition for 70 gigawatts of solar capacity by 2035 required a significant increase in both ground-mount and rooftop solar and we were clear that the extensive deployment of rooftop solar, on domestic, industrial and commercial property to make effective use of available surfaces, was a priority with the potential to help protect agricultural land and our rural landscapes.
In November 2023, the Department for Housing, Communities and Local Government announced expanded development rights, making it easier for more homeowners and businesses to install rooftop solar panels without the need for planning permission in most cases.
The last Conservative Government also consulted on plans for a Future Homes Standard that would ensure all new homes can be built zero-carbon ready, including by using solar panels where appropriate. I sincerely hope the new Government will take the views gathered during the consultation into consideration and press forward with the last Government's work to encourage more solar panels on new homes.
Like you, I believe the Labour Government must support the deployment of rooftop solar across the country and it is very welcome news they are continuing the Solar Taskforce created by the last Government to bring together key players from government, industry, regulatory and other relevant organisations to drive forward an increase in solar power.
Regarding the New Homes (Solar Generation) Bill, I understand this would see solar panels mandated on all new homes. While I share the view that solar has an important role to play in helping us decarbonise the power sector, it is worth noting that some roofs are not suitable for solar panels due to structural strength, difficulties with maintenance access or the direction of the building. I therefore support work to encourage the use of solar panels on new homes where appropriate.
As you may be aware, the Labour Government decided not to support this Private Members’ Bill on the 17th January and I have provided the link to the debate transcript here: New Homes (Solar Generation) Bill - Hansard - UK Parliament.
Finally, I would like to say how proud I am that the UK is the first major economy to halve its emissions, cutting them by 50 per cent between 1990 and 2022 while growing our economy by 79 per cent. I believe, however, that our route to net zero must balance ambition with realism. I am aware this Labour Government has not yet made any estimate as to the amount of non-residential building roof space that is available and suitable for the installation of solar panels. Without knowing this, tripling existing solar capacity by 2030 will be incredibly difficult. I look forward to examining the Government's plans when its 'Solar Roadmap' is published.
