Real world insights
Insights from the field, observations from live assets, and a closer look at how renewable infrastructure performs in the real world.


Government support and what it means in practice
Government support is accelerating large-scale solar in the UK, but approvals and capacity alone don’t guarantee performance. As more assets come online, the focus shifts to how they are managed, maintained, and integrated into an increasingly complex energy system.

When heat doesn't mean higher performance
Warm weather may look ideal for solar generation, but higher temperatures can reduce panel efficiency and place additional strain on electrical components. This piece looks at what really happens during hotter conditions, and why understanding site behaviour matters just as much as sunlight.

Consistency Over Time
When people talk about solar performance, the conversation usually centres around numbers; monthly output, targets, whether a site is over or under where it should be. And that’s all useful, it gives you a snapshot of how things are going at a given moment. But over time, what tends to matter more isn’t whether you’ve had a particularly strong month, it’s whether the site behaves consistently.

Why performance will define the next decade of UK solar
Something interesting is happening in the UK solar market, and it is easy to miss if you are only looking at headline capacity numbers.
