Solar PV
Not every project is straightforward.
Our Solar PV options
Ground-Mounted Solar PV
Working with our specialist Solar Mounting division, we design and deliver ground-mounted solar systems that perform on tricky terrain, tight sites, or working land.
From uneven ground and contaminated sites to active farmland — even sheep grazing — we create layouts that make the most of your land.
Our in-house engineering team takes ownership from day one, ensuring layouts are practical, systems are efficient and every installation is built to keep working effectively for decades.
Why choose Alt for ground-mounted solar?
Mounts designed for your land and operations
Systems engineered for decades of reliable performance
Solutions that adapt to site challenges
Ready to connect with battery storage and monitoring systems
What we do
Carry out feasibility studies and plan site layout
Carry out relevant ground survey work
Engage directly with your local electricity network
Design and deliver detailed technical solutions that meet your project’s requirements
Provide access to commercial arrangements to protect long-term value and returns
Check every system against industry standards for safety, structural integrity and performance
Roof-Mounted Solar PV
Installing solar on a live building isn’t just panels and brackets. It takes careful planning, coordination and smart engineering. Our roof-mounted systems are built for operational sites where safety, access and continuity matter.
From warehouses and commercial buildings to schools, hospitals, public sector facilities, and new developments, we integrate solar into your existing infrastructure while keeping your operations running smoothly. This includes fire strategies, insurance requirements, and compliance with standards such as RC62.
Why choose Alt for roof-mounted solar?
Work continues with minimal disruption
Connects with batteries to store power and cut peak costs
Explore different ways to fund your solar project, including CAPEX, leasing or PPA
Keep track of performance and spot issues quickly
What we do
Coordinate with electricity networks for safe connection
Handle planning and compliance requirements
Assess structure and manage roof loads
Provide access to funding options, including combined roof refurbishment and solar
Check every system against industry standards for safety, structural integrity, and performance

Frequently asked questions
PV stands for “photovoltaic,” which refers to the process of converting sunlight into electricity. Solar PV systems use panels made of semiconductor materials to capture sunlight and generate direct current (DC) electricity for use in buildings.
Solar PV systems generate electricity from sunlight to power business operations. The energy produced can be used on-site, reducing reliance on the grid and lowering energy bills. Any excess electricity can sometimes be exported back to the grid to generate revenue, depending on system setup and agreements.
Solar PV systems help businesses reduce energy costs, lower carbon emissions, improve energy independence and generate revenue. They also protect against rising electricity prices and can enhance sustainability credentials, which is increasingly important for customers, investors, and regulatory compliance in the UK.
Savings depend on system size, energy usage, and site conditions, but many UK businesses can reduce electricity bills by 20–50%. Over time, solar PV offers strong return on investment, especially when combined with energy storage or by maximising on-site energy consumption.
Most commercial buildings can support solar PV, especially those with large, unobstructed roof space. Factors like roof orientation, structural integrity, network capacity and shading are assessed during a survey to determine suitability and system performance potential.
Our installation timelines can vary depending on system size and complexity, but most commercial solar PV projects are completed within a few weeks. This includes DNO application, planning, design, and installation, with minimal disruption to daily business operations.
Solar PV systems require minimal maintenance, typically limited to occasional cleaning and routine inspections” to “with recommended routine inspections and occasional cleaning”. Suggest amending to something like “we can provide O&M services to support businesses track performance and identify issues.
Most solar panels have an average lifespan of 25-30 years. While energy output gradually declines over time, high-quality panels often continue producing electricity well beyond their warranty period with proper installation and minimal maintenance.
