The Future of Solar Energy in the UK: Insights For Landowners

Solar energy has long been considered a supporting act in the UK’s energy transition. But the reality is changing quickly as technology improves.

As someone who spends much of their time in conversations with developers, landowners and policymakers, I’m seeing first-hand how the future of solar energy is shifting from marginal to material.

This isn’t just about falling costs or rising capacity either. It’s about positioning solar as a pillar of our national energy infrastructure. It’s about proving that solar can deliver flexibility, support decarbonisation and make meaningful use of underutilised land.

The solar projects in development today are not the same as those we saw ten years ago. They’re smarter and more integrated. And sometimes, they’re hybridised with battery storage. Developers are starting to pursue these projects with clearer funding, more sophisticated data and greater urgency than ever before.

I’ve personally seen a notable uptick in landowners exploring solar for the first time. This is particularly true of those who’d previously focused on wind. I’m also seeing developers offering higher lease rates and faster due diligence turnarounds.

All of this suggests that the future of solar energy in the UK is no longer in the background of the UK’s energy mix. It’s a strategic part of meeting the country’s net zero obligations.

So, landowners who move quickly may find themselves in a rare, advantageous position.

Where Are We Now?

Solar power currently provides about 5 per cent of the UK’s electricity and sits at just under 20 gigawatts (GW) of installed capacity. That may sound modest compared to wind, but solar is on a steep trajectory.

As of Q2 of 2025, 2.6 GW of new renewable capacity was added to the UK development pipeline (of which more than a half was solar). Plus, applications for solar and storage projects increased by more than 250 per cent year-on-year.

Solar’s strength lies in its adaptability.

It’s fast to build, scalable at everything from rooftop to utility scale (AKA large-scale solar farms that generate electricity for the grid), and increasingly compatible with storage and hybrid systems. That means it can fill gaps in supply, respond to demand peaks and support decentralised energy goals.

The UK government’s Solar Roadmap, published in 2025, sets out a clear ambition: 45 GW of installed solar capacity by 2030, and 70 GW by 2035.

Hitting those targets would require a major acceleration in solar deployment (particularly of large-scale, ground-mounted projects). But from what I’ve seen in the last few years, developers are clearly moving in that direction.

So, land availability is now the central concern.

What’s Driving the Future of Solar Energy?

Several major shifts are reshaping what’s possible and likely for solar in the next decade.

Technology is getting smarter

Advances in module design (including bifacial and perovskite panels) are boosting overall output per acre.

When you bring in smart inverters, better site tracking and more integrated asset monitoring, it’s easy to see why solar projects are becoming more efficient and bankable than ever before.

Battery storage is also changing the economics of the sector.

While solar once struggled with intermittency, co-located battery systems now let developers shift exports to when value for energy is higher.

For landowners, this means more consistent income streams and better long-term returns.

Solar is becoming more investable

Levelised cost of energy (LCOE) for solar has continued to fall, making it one of the cheapest forms of new generation (even without subsidies).

Pair that with streamlined planning in many parts of the UK and a more predictable regulatory environment, and it’s clear why investors are starting to get more excited about solar.

More developers are now offering upfront premiums, competitive lease rates, and options for hybrid wind-solar or solar-storage configurations.

Hybrid projects are the new frontier

Hybridisation is one of the most unique parts of the future of solar energy in the UK.

Developers are no longer thinking in terms of single technologies. Instead, they’re designing sites that combine solar with batteries or agriculture (agrivoltaics).

These projects can also be combined with wind to create multi-revenue models that maximise land use.

For rural landowners in particular, this opens new doors.

A parcel of land that developers once saw as less-than-ideal for wind could now host a co-located solar and storage system. Or perhaps a dual-use setup that maintains farming operations beneath solar canopies.

Either way, there are far more options on the table for landowners going forward.

What Are the Risks and What Needs to Change?

Now, no energy transition is frictionless.

Despite serious momentum over the last few years, solar still faces several constraints that make boosting capacity across the UK more difficult:

• Grid capacity remains a critical bottleneck. In many areas, connection timelines still exceed five-to-seven years on the lower end.

• Planning friction persists. This is particularly true in areas where local authorities lack the experience or confidence to approve large-scale photovoltaic (PV) projects. It’s improving, but current progress is still slow.

• Land-use conflict is also real. As solar expands, so do questions about biodiversity, landscape impact and community consent.

These aren’t fatal flaws by any means, but they’re important to navigate.

Policy support alone won’t unlock solar’s potential unless we pair it with grid reform, investment in planning capacity and clearer community benefits.

What Should Landowners Do Now?

For landowners, the question isn’t just whether to consider solar, it’s when. And in my opinion, the answer is now.

Developers are actively seeking grid-adjacent land, especially in areas that were previously overlooked or underutilised. Sites with light sloping topography, good southern exposure or proximity to substations are in higher demand than ever before.

And land that may not have been viable five years ago could now be quite commercially attractive. If you pair this with batteries – or if your site has an existing feature that makes it ideal for an upgrade or replacement solar project – it could make your land even more appealing.

Even if your site isn’t ready to host panels tomorrow, an early feasibility assessment can secure your place in the queue. As the National Energy System Operator (NESO) provides Grid connection offers on a first-come, first-served basis, it’s wise to get your foot in the door sooner rather than later.

Looking Ahead

The future of solar energy in the UK looks bright.

It’s now a present-day opportunity backed by improved national policy, better technology and a stronger market appetite. Solar won’t displace wind as the UK’s main renewable energy source anytime soon. But it’ll play a defining role in the next generation of clean power projects across the country.

Whether that’s through hybrid systems, smart grid integration or new land use models, solar is becoming one of the most agile and investable parts of the UK’s energy landscape.

If you’re a landowner, the window is wide open. But it won’t stay that way forever. Sites that secure grid access and developer attention early are more likely to attract favourable lease terms and avoid delays down the line.
