STA Appoints Chris Hewett as New Chief Executive


Chris, who has been leading on policy for the STA since June, brings 25 years’ of experience having previously headed up the Environment Agency’s climate change team. He has previously also worked for Green Alliance, IPPR and the Finance Innovation Lab at senior level.

STA Chair Jonathan Selwyn said;

We are delighted to have appointed Chris to the role of Chief Executive. He brings tremendous experience and skills to the Association at this critical juncture. Solar is poised to play a lead role at the heart of the UK’s smart energy transformation, but making the economics of solar work today depends on pursuing every opportunity to boost markets, including securing effective regulatory change.

“The Board has been hugely impressed by Chris’s intelligent & strategic approach, and we look forward to working with him in championing solar’s remarkable potential during the coming years

Chris Hewett said;

I am honoured to be leading the solar industry into its next phase of growth.

As we move away from a subsidised market, our role at the STA will be to showcase the brilliance of the solar and storage industries, to identify and promote effective new business models, to safeguard quality, and to secure a level playing field in terms of policy and market frameworks.

“The solar industry is bursting with people and companies who are passionate about what they do and who remain utterly committed, despite current challenges. That is why it is such an exciting sector to work in and why I am confident we will prevail sooner rather than later. There are few more enthusiastic advocates of solar than Paul Barwell, who I am succeeding. Paul led the solar industry in the UK through unprecedented growth which has been a fantastic achievement that I am determined to build on

Chris will begin his new role at the beginning of January.  In the meantime, he will continue to work alongside current CEO Paul Barwell, who will help the transition with the executive and the Board and will leave at the end of January.


In a move which further strengthens the STA, and which recognises her huge contribution to the industry over many years, Leonie Greene has been promoted to a Director role in the organisation. She will be working closely with Chris and the Board to further develop the STA’s forward strategy as well as continuing to lead on parliamentary and external affairs.


The STA will be reviewing its strategic plan early in the New Year and members will be invited to contribute to this at the AGM in Spring.
