Ground-mounted Solar Panels: Alternatives

Jim Shannon Excerpts

Tuesday 14th April 2026 Westminster Hall

[Lincoln Jopp (Spelthorne) (Con)]

I beg to move,

That this House has considered the matter of alternatives to ground mounted solar panels.

It is a pleasure to serve under your chairship, Mr Stringer. I sensed the people coming into the Chamber in the last couple of minutes and I felt a quickening. It was like energy coming together, which is completely appropriate given what we are here to debate: alternatives to land-based solar panels.

The context in which I wish to couch this debate is twofold. One aspect is local and one slightly more geostrategic. People say that in politics, where you sit defines where you stand. Hon. Members may or may not know that I am the proud Member of Parliament for Spelthorne. I sometimes feel the need to remind hon. Members that Spelthorne is not in Lincolnshire or Lancashire; it is, in fact, everything south of Heathrow airport until hon. Members get to the River Thames.

When I was elected, at the last election, to be the Member for Spelthorne, I looked at a very big map of the constituency—hon. Members will be very surprised to learn that I used to be in the Army, and there used to be a very good saying in the Army: “If you don’t know what’s going on, get a bigger map”—and I identified four enormous blocks of blue. That was half of London’s drinking water in four raised reservoirs. Being a practical man, I thought to myself, “Well, there aren’t many votes in there.” I also thought to myself that we cannot really build many homes there.

I did further research and it turns out that in 2016, on the Queen Elizabeth reservoir in a neighbouring constituency, a large technology demonstrator for floating solar was laid down, and ever since it has produced 6.3 MW of power—enough to power about 2,000 homes. That was at the time the largest one in Europe; back in 2016, we were leading. I looked into the situation further in order to see whether we were world-leading, but it turns out that we were not particularly, and that floating solar has been deployed to a greater extent in China, India, Vietnam and Israel. We will come in due course to the benefits of floating solar as an alternative to land-based systems.

I want now to return to the more national context. Frequently, we are led to believe that alternative sources of energy can be something of a zero-sum game—when someone takes one step forward, someone else has to take one step backwards. As I am sure we will hear, in large parts of the United Kingdom there are proposed large, land-based solar farms, frequently on very good agricultural land, so the zero-sum game between food security and energy security needs unpicking.

[Jim Shannon (Strangford) (DUP)]

I congratulate the hon. Member on bringing forward a debate on this massive issue. Is he aware that there are roughly 600,000 acres of unused, south-facing industrial rooftops in the United Kingdom that could be utilised before we industrialise the countryside? The Government must look at those in order to utilise already built heritage and leave our countryside as it is to produce the food that we need.
