Your Commercial Solar Roadmap
Discovery & Consultation
We begin with a discovery session to understand your energy goals, building use, and ROI expectations. Once aligned, we book a tailored consultation to present the ideal system setup, based on your site, targets, and operational priorities.
Finance Strategy Call
Next, we bring in our finance team to explore every available model, from CapEx to PPAs and lease-backed solutions and show you what’s possible. You’ll see clear comparisons, projected returns, and the fastest path to value.
Site Inspection & Project Kickoff
We meet on-site to carry out a detailed inspection, finalise the system design, and confirm all technical details. Once planning and DNO approvals are cleared, contracts are signed, and we move straight into installation.
Minimal disruption to business operations.
High-quality components and workmanship.
Maintenance And Monitoring
Post-installation, we monitor system performance and handle maintenance, ensuring your solar system operates at peak efficiency, while you enjoy ongoing savings.
Real-time monitoring for optimal performance.
Prompt support and troubleshooting.
Fully Funded Solution
Flexible financing options
We provide businesses with a fully funded, all-in-one solar solution that covers everything from design and installation to ongoing operation and maintenance.
Currently, around 80% of the UK’s industrial energy still comes from carbon-based fuels.
Our flexible 15-25 year Power Purchase Agreements (PPAs) let your business benefit from solar energy without the financial or operational complexities of building your own system.
