Ground-mounted Solar Panels: Alternatives

John Hayes Excerpts

Tuesday 14th April 2026 Westminster Hall

[Edward Morello]

My hon. Friend is 100% right. Wherever possible, we should generate and use on site. The problem so often—I will come to this point in my speech—is that the value of anything that is exported to the grid fundamentally underlines any kind of investment model when we are looking at on-site generation.

[Sir John Hayes (South Holland and The Deepings) (Con)]

I sent a note, which you were kind enough to mention, Mr Stringer, to apologise for entering the debate late, but I am delighted to be able to contribute.

The hon. Gentleman must surely know that renewables need to face the same tests of cost-effectiveness as all other kinds of generation. For example, the concentration of offshore wind, with very large turbines, a single point of connection to the grid and large amounts of energy, contrasts with the peppering of the country with onshore turbines in small numbers and with multiple connections to the grid. Similarly, putting solar on grade 1 land is just not sensible. Does the hon. Gentleman agree?

[Edward Morello]

I can certainly agree with the argument that putting solar on grade 1 land should be avoided wherever possible. The right hon. Gentleman may be interested in the recent report of the Joint Committee on the National Security Strategy on our adversaries’ attempts to cut subsea cables, and on the implicit danger of having so few connection points with such concentrated areas of offshore generation, as we have seen with recent Russian activity. I will happily pick up that point with him afterwards.

About two thirds of UK solar capacity is ground-mounted, but there are concerns about where developments are located, particularly those built on high-quality agricultural land. I echo the comments of the hon. Member for South Northamptonshire (Sarah Bool): I have never met a farmer, especially in West Dorset, who got into farming because they wanted to grow solar panels. Farmers want to produce food, but we must acknowledge that after years of pressure on farm incomes and pressure on them by this Government, some see solar as one of the few reliable ways to keep their farm operating.

We are asking more and more of our countryside. We want it to produce food, support biodiversity, generate renewable energy, capture carbon, provide housing, and support tourism and recreation. We need guidance to identify where solar is most appropriate, steer it away from the best agricultural land wherever possible, and encourage dual-use schemes that allow land to generate energy while still supporting farmers and nature—

[The Minister for Energy (Michael Shanks)]

It is a pleasure to speak in this debate. I congratulate the hon. and gallant Member for Spelthorne (Lincoln Jopp) on securing it, particularly because I unfortunately missed his Adjournment debate, which I heard was one of the most enthusiastic Adjournment debates we have ever had on this topic. I was delighted to hear him repeat much of that same speech, because I did of course read it in Hansard. The map joke was there in the Adjournment debate, and it was there again today. We appreciated it all the same, and it was great to hear it in person. I thank him for securing the debate, and I genuinely thank him for the enthusiasm he has shown for floating solar. I will come back to that in a moment.

I was also pleased to hear the hon. and gallant Member say that he believes in climate change. That should not be breaking news to anyone, but when we hear Conservative Members stand up and confirm that science is in fact science, it is none the less a relief to me. I was delighted to hear that. However, the challenge—and I will come back to this point—is that, as much as there is a recognition that climate change is a threat, there is also a distancing from any of the actions that would help us to tackle it, and that is simply not a sustainable position for anyone to hold.

If we think about food security, water security and national security, all of them would be put at huge risk by not tackling the climate crisis. This is a very real challenge for us to deal with at the moment. That more dangerous and insecure world is exactly why we are embarking on the clean power mission.

[Sir John Hayes]

While the Minister is on the subject of science, would he turn his attention to agronomy? He will know that only around 15% of the land in the United Kingdom is grade 1 and 2. Much of that is in the east of England and, indeed, in my constituency in Lincolnshire. Lincolnshire has been targeted by solar developers, with countless large solar plans in the offing. Will the Minister recognise that those two things cannot be squared? We cannot have the most productive and versatile land being used up for solar at the cost of our food security.

[Michael Shanks]

I was going to come to the trading of statistics later in my speech, but let me do it now, because there is a fundamental point around the disingenuous trading of statistics on land use. My hon. Friend the Member for Bournemouth East (Tom Hayes) made a valiant effort at trying to correct that, but let me give Members some sense of this. At the end of 2024, ground-mounted solar panels covered an estimated 0.1% of the total land area of the UK. Even if we achieve the ambitious targets that we have set out in the clean power action plan, they will be expected to cover 0.4% of the total land area and 0.6% of agricultural land. That is if we achieve our hugely ambitious targets.

The arguments that I will make in this speech are exactly those that the previous Government made when they spoke from the Dispatch Box. There was a bright-eyed and bushy-tailed Energy Minister who spoke about the dramatic rise in global energy prices following the invasion of Ukraine, the urgency of building a renewables-based system, and how critical it is for us to meet our 70 GW target for solar in the UK by 2025— the previous Government’s target was a fivefold increase.

The now shadow Minister, the hon. Member for West Aberdeenshire and Kincardine (Andrew Bowie), pretends that that was not the Conservatives policy for 14 years, and we now hear a litany of ideas—roadside solar, rail solar, floating solar—but none of them was driven forward in the 14 years that they were in government. Forgive me if I think that it is a little bit rich for them to be oppositionist, not having driven any of it forward when they were in government.
