UK Solar Capacity Surges in 2025: What does this mean for Solar Power in the remainder of 2025 and beyond?

In a recent report by Solar Power Portal, it was announced that so far in 2025, the UK has installed over 2GW of new solar capacity. That is more than the entire total installed in 2024. This rapid progress signals a growing shift toward clean energy, and it’s happening faster than expected.

At Day 1 Connectivity, we have seen a similar trend emerge so far this year, with an increase in the number of homes, farms and businesses turning to solar and battery storage as a cost effective, sustainable energy source. We are proud to be part of this momentum.

Why This Matters

The 2GW mark isn’t just a technical achievement, it’s a sign of shifting mindsets. Across the UK, more people are recognising the benefits of energy independence, not just for sustainability, but for long-term cost control and reliability.

Take our recent project at a farm in Harefield, where we installed a 15kW EcoFlow battery paired with 9kW of solar generation. The system delivers instant off-grid capability, allowing the farm to reduce reliance on the national grid and stabilise its energy costs, all while contributing to a cleaner future.

What does this mean for the remainder of 2025?

The outlook is bright. Here’s what we expect as solar growth continues:

Ongoing momentum: Solar capacity is likely to exceed expectations in 2025, driven by rising awareness, evolving tech, and falling costs.
Greater focus on storage: Battery systems will become increasingly central to smart energy strategies, especially in rural and off-grid settings.
More support for homes & farms: As government and industry adapt to this growth, additional incentives and grid flexibility may follow.

The time to Act is Now.

If you’ve been thinking about solar and battery storage, there’s never been a better time to get started.

At Day 1 Connectivity, we deliver high-performance solar and battery systems that provide real-world benefits from the moment they go live. Whether you’re looking to lower bills, boost resilience, or support your sustainability goals, we can help make it happen.
