New Homes (Solar Generation) Bill

Debate between Nesil Caliskan and Adam Thompson

2nd reading
Friday 17th January 2025 Commons Chamber

[Adam Thompson]

I thank the hon. Member for her intervention, and I will cover some of those points shortly. I broadly agree with the sentiment of what she said.

The Bill’s aims, in promoting the installation of solar panels on all new homes, feed into the Government’s overall intent, and I am pleased about that. I note, however, that it is undeniable that solar farms, especially the larger ones, are much more efficient than rooftop solar for a whole spectrum of reasons. Rooftop solar panels are constrained by the size, orientation and structural limitations of individual buildings, while solar farms are optimised for maximum energy generation. The difference in output can be as high as 30%. Economies of scale mean that the cost to install, maintain and centralise the supportive infrastructure notably reduces the ratio of cost per unit of energy generated by solar farms. That is not to say that I do not support rooftop solar, because I very much do, but solar farms are a highly scalable, cost-effective means through which to achieve the green energy transition.

[Nesil Caliskan (Barking) (Lab)]

Is that not exactly the point—we need to do both, because that creates a subsidy for more opportunities to have rooftop solar panels?

[Adam Thompson]

I completely agree. It is not about one solution versus another, but a diverse, broad array of solutions, all feeding into a grand, greener future.
