Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what plans does his Department has to support the growth of solar energy in the UK.

Solar PV has been a UK success story, with rapid deployment over the last 10 years. Over 99% of the UK’s solar PV capacity has been deployed since May 2010, and over a million homes have installed solar on their roofs.

Solar is a key part of the Government’s strategy for low-cost decarbonisation of the energy sector. Achieving our ambitious 2050 Net Zero target will require significant increases in renewable electricity generation, and we will need to increase deployment across a range of technologies, including solar PV. Our recent Energy White Paper stated that we will need sustained growth in the capacity of solar over the next decade alongside onshore and offshore wind.

That is why the Government announced on 2 March 2020 that large scale solar PV projects will be able to compete in the next Contracts for Difference (CfD) allocation round. The round is planned to open in December 2021 and will aim to deliver up to double the renewable capacity of the last round, potentially providing enough clean energy for up to 10 million homes.

We also support small scale solar projects through the Smart Export Guarantee scheme, which requires electricity suppliers to offer a tariff to buy electricity exported to the grid by small low-carbon generators – typically households that have installed solar panels.

Solar is also an important part of the Government’s strategy for energy efficient buildings and reducing fuel poverty. The Public Sector Decarbonisation Scheme, the Social Housing Demonstrator Fund and the Green Homes Grant Local Authority Delivery Scheme all include solar panels as an eligible measure.

In April next year we aim to launch the Green Heat Network Fund, which is intended to run for three years and will focus on helping new and existing heat networks to adopt low and zero carbon technologies. We recently consulted on proposals for the scheme design and our consultation document looked at the ways in which a number of low-carbon technologies, including solar thermal, might be treated. The consultation document can be found on gov.uk (https://www.gov.uk/government/consultations/green-heat-network-fund-proposals-for-the-scheme-design ). The consultation period ended on 29 January and we aim to publish the Government’s response later in the summer.

Taken together this support reflects our commitment to reach our net zero ambition, through a sustainable, diverse, energy system.
