The UK's solar energy market is entering a major growth phase. Large-scale projects are adding significant renewable capacity to the national grid from the Gate Burton Energy Park to the Mallard Pass Solar Farm. Over 660 solar PV projects have been approved in the past year, representing 3.8 gigawatts (GW) of clean energy capacity. These projects are helping the UK meet its net zero targets and opening doors for businesses of all sizes to participate in large scale energy projects.
The case for renewable energy has never been stronger. With energy price volatility, tightening carbon regulations, and growing pressure from stakeholders, many UK companies are rethinking their approach to energy procurement.
But not every business can install solar panels on-site, whether due to limited space, tricky infrastructure, or landlords who aren’t quite on board and shorter lease terms.
Virtual Power Purchase Agreements (VPPAs) provide access to large-scale solar power without the upfront capital or logistical hurdles. You get clean energy credentials and contribute to national renewables growth.
How VPPAs and solar farms work together
A Virtual Power Purchase Agreement (VPPA) is a long-term contract that allows businesses to purchase renewable energy from solar or wind farms, without needing to connect to them physically. Instead, the clean energy enters the grid, while the business receives the associated renewable energy certificates and price benefits.
This model offers multiple advantages for UK businesses:
- Price stability amid fluctuating wholesale energy markets
- Progress towards sustainability and ESG goals
- Support for new renewable infrastructure
One high-profile example is Vodafone, which signed a VPPA covering five UK solar farms. The deal will deliver 216 GWh of renewable electricity per year, helping the company meet its environmental targets while ensuring the solar farms have the financial backing to move forward.
VPPAs underpin the delivery of new solar capacity. They provide developers with long-term revenue visibility, enabling project financing and construction.
How UK businesses benefit from off-site solar and VPPAs
Engaging in a VPPA means more than just cleaner energy for UK businesses. It’s about gaining control over energy strategy, delivering real progress on net zero targets, and creating a positive brand narrative.
Benefits of solar VPPAs for businesses include:
- Fixed-price, long-term energy procurement
- Reduced exposure to energy market volatility
- Tangible ESG and carbon reduction outcomes
- Enhanced corporate reputation with investors and customers
The model is scalable and collaborative. Multiple businesses can now share in the output of a single solar farm site, making clean energy more accessible and financially viable for companies of all sizes.
Energy from solar farms isn't just for big businesses
There’s a common misconception that corporate renewable energy deals, primarily through VPPAs, are only feasible for large, multinational companies. The reality is changing fast.
Thanks to the growth of shared solar projects and more flexible contracting models, mid-sized businesses can now access large-scale renewable energy projects. Many solar farms are designed to accommodate multiple buyers, allowing companies to purchase just the portion of energy that matches their needs. Think of it as adopting a part of a solar farm.
This means:
- You don’t need a massive energy footprint to participate
- Contracts can be structured to suit your scale and goals
- Smaller businesses still gain the same long-term pricing, carbon reductions, and reputational benefits
Whether you’re a regional manufacturer, a logistics firm, or a professional services company with sustainability goals, solar VPPAs are becoming a realistic and strategic option. It’s for forward-thinking businesses of all sizes.
Whats involved in developing a solar farm
Before entering a VPPA or solar project, it’s essential to know the solar farm stacks up, financially, legally, and operationally.
At Green Shield Group, we work with both solar developers and energy off takers. For developers, we ensure projects are viable and investment-ready. For off takers, we secure long-term clean energy at the right price through well-structured VPPAs.
With insight across planning, grid, pricing and ESG, we align both sides to create smart, sustainable partnerships.
Our solar farm feasibility study helps de-risk early-stage projects and gives off takers confidence in what they’re buying into.
Conclusion: why the time for solar is now
The UK’s solar energy landscape is evolving quickly. From supportive government policy to a surge in large-scale solar farms, the conditions are right for businesses to act.
Virtual Power Purchase Agreements provide a commercially sound, environmentally responsible way to participate in the future of renewable energy. They offer energy price certainty, sustainability credentials, and the opportunity to support the UK’s clean energy transition.
This is the moment to move for businesses looking to lead – not just comply.

Frequently Asked Questions (FAQs)
1. Do I need solar panels on my building? No panels needed. VPPAs connect you to off-site solar farms, so you can benefit from clean energy without installing anything on-site.
2. Are VPPAs just for big companies? Not anymore. Shared VPPAs now make renewable energy accessible for mid-sized and smaller businesses too.
3. How do VPPAs support sustainability goals? They help reduce Scope 2 emissions and support net-zero targets by directly funding new renewable energy projects.
4. Can companies share a solar farm? Yes. Many VPPAs are structured so multiple businesses share the output, making it more affordable and scalable.
5. How long does setup take? Typically a few months from initial talks to contract. It’s quicker if the solar farm is already in development.
