Precision engineering meets renewable energy
Solar and energy storage solutions that reduce costs and carbon, maximise returns and deliver compliant, future-ready energy systems.
Alt-Group delivers tailored solar, storage and integrated energy systems to businesses, communities, developers and the public sector. From feasibility and design to installation and long-term management, we help clients cut costs, unlock value and support sustainability goals.
We design and deploy fully integrated solar and battery storage systems tailored to your site, your goals and your future. Every system is engineered in-house to deliver maximum efficiency, reliability and returns — today and for the long term.
Powering Sites. Maximising Returns.
Engineered to suit all sites and built for lasting performance. Our rooftop and ground mount systems are designed to integrate seamlessly with your operations, maximise efficiency and reliability whilst delivering long-term energy and financial returns.
Smarter storage for greater control.
Our battery systems optimise self-consumption and reduce peak costs, while unlocking extra solar potential even on constrained grid connections — fully engineered for safe, reliable, long-term performance.
Turn parking into power.
Our solar carports provide energy, shelter and optional EV charging, designed and installed to meet commercial and public-sector expectations for smarter energy use.
Built for you. Built to last.
Every site is different, so our ground-mounted systems are designed to fit your terrain, not fight it. Sloping, rocky, contaminated or tight spaces—we engineer solutions that perform, last for decades and are made right here in the UK.
Insight before you invest. Before you invest time or budget, we assess your site, energy profile and commercial goals to identify the right solution. Feasibility studies and financial modelling give you a clear picture of what’s achievable and the returns you can expect.
Clarity before you commit. From grid applications and planning to structural and ground assessments, we validate every element upfront. We ensure your project is compliant, build-ready and set up to succeed before construction even starts.
Engineering that performs. Our in-house engineers create designs built for the real world. Electrical, structural and system optimisation are all covered, so installations are safe, reliable and high-performing. Ready-to-Build (RTB) designs let you move confidently from plan to project.
Safe and efficient delivery. From rooftop arrays to utility-scale ground-mount systems, we deliver projects that last. In-house teams, strict CDM compliance and proven delivery models keep construction safe, efficient and high-quality — no corners cut, no over-engineering.
Keep your system performing. Your system is an asset, not a project to forget. Our in-house teams monitor, maintain and optimise installations throughout their life, ensuring maximum uptime, reliable generation and long-term returns — all backed by a practical, hands-on approach.
From farms and factories to public services, developers and property portfolios, we design solar and storage solutions that deliver measurable impact today and long-term value tomorrow.
Alt-Group delivers tailored solutions across Agriculture, Public Sector, Commercial and Real Estate projects, bringing deep sector-specific expertise.
Long-term partnerships with leading organisations reflect our reliability, quality and consistent delivery on complex energy projects.
From feasibility to design, construction and O&M, we manage every stage to minimise cost, risk and ensure timely delivery.
Quality assured processes, MCS, NICEIC, Safe Contractor, Achilles accreditations and CDM compliance with robust H&S standards give peace of mind on every project.
We optimise energy performance, reduce carbon and deliver long-term renewable assets that align with ESG and net-zero goals.
