UK solar is entering a new phase

By Darren Lewis | 20-11-25

I recently read an article that pointed out something we are seeing every day on the ground.

Even with all the challenges around weather, regulation and grid capacity, UK solar is still pushing forward. In some ways, it is progressing faster than anyone expected.

What interests me is not the headline about growth, but what sits behind it.

Progress in imperfect conditions

The UK is not the easiest environment for solar. We all know that.

Shorter days, variable weather, planning delays, grid bottlenecks — none of this is new.

And yet, even with those limitations, the market keeps expanding. More ground-mount sites. More large-scale portfolios. More demand from investors.

That tells me the industry is moving into a phase where installation is only the first half of the job. The second half is how well we run what is already built.

Performance matters more than capacity

There are moments now where solar covers a sizeable share of the UK’s electricity demand. That is a major shift.

But as solar becomes a larger part of the supply mix, the expectations rise. A small loss in performance is no longer a minor inconvenience. It becomes a measurable financial impact and a reliability concern.

That is why the operational side of solar is becoming just as important as deployment.

If an asset is not managed proactively, the gap between potential output and actual output grows very quickly.

Challenges are real — and manageable

The article pointed out several pressures facing the industry. They are accurate. Weather reduces predictability. Policy moves slowly. Grid infrastructure is behind where it needs to be.

But these factors do not decide the success of an asset.

How you operate the site does.

When you react late, the problems grow.

When you monitor closely, intervene early and plan long term, these challenges become part of the landscape rather than threats.

That is where good O&M earns its value.

What this means for the next chapter of UK solar

We have reached a point where the UK solar industry is maturing.

The headlines are still focused on new capacity and ambitious targets, but the real difference will be made in day-to-day operations.

The winners will be the companies treating assets with the care and attention of ownership. The ones who look past the installation and focus on performance, reliability and long-term value.

Because that is where the real opportunity is now.

Because we care.
