Designing solar that works: Lessons from two very different projects
Today, more and more businesses are turning to solar power to improve sustainability and reduce operational costs. But a successful system is far more than simply choosing the right panels. It requires a bespoke, expert design, as every site, grid connection, and operational requirement is different.
At Carman Contracting, our end-to-end approach ensures that every system we deliver is tailored to the project, the client and the wider energy environment. Two recent projects for clients Tappers Funeral Service and Flexicovers, are perfect examples of how practical expertise can turn very different challenges into successful installations and long-term energy savings.
The increase in solar installations
Solar now plays an important role in meeting Part L, the energy efficiency requirements for buildings, and SAP (Standard Assessment Procedure), which measures a building’s energy performance. Public and private sector organisations are investing in renewables not just for compliance, but to reduce carbon emissions and improve resilience.
This shift has created a strong demand for expert partners who can design and integrate renewable technologies within complex construction environments. For contractors, local authorities, and businesses, working with an MCS (Microgeneration Certification Scheme) accredited installer like Carman provides assurance that systems will meet regulatory standards and deliver energy benefits from the start.
Redesigning for DNO limitations
We recently delivered solar PV systems across two sites for Tappers Funeral Service in Poole. The installation of 134 panels on three new barns at the Harbour View crematorium and burial ground site went without a hitch, but the project at their Parkstone Road head office highlighted the importance of adaptive engineering.
The original design required a three-phase supply, but midway through the installation, the Distribution Network Operator (DNO) notified us that it could not deliver this.
Instead of delaying the project or reducing generation capacity, we redesigned the system to work effectively on a two-phase supply. This required careful management of energy generation to stay within power export limits and keep the system operating safely within grid constraints. To further complicate the project, the client also increased the required generation partway through, requiring flat roof areas to be brought into the design.
This is a clear example of why you need a renewables partner who can problem-solve quickly and effectively. A grid limitation that could easily have disrupted the project was resolved through our technical agility and practical understanding of how to redesign the system without sacrificing performance.
Delivering performance at scale
Amongst Carman’s larger solar installations to date has been the 84 kWp generation project for Flexicovers, a boat cover supplier in Poole. For power generation over 50kW, G99 compliance requires a more detailed application progress and rigorous testing than smaller systems, involving specific ENA (Energy Networks Association) submissions that demonstrate protection settings compliance. With 160 roof-mounted panels, this project presented a very different challenge: instead of redesigning for grid constraints, it required meticulous logistical planning to deliver a large-scale system at the company’s new factory premises in a busy industrial setting.
HGV deliveries, specialist lifting equipment and strict site safety procedures all needed to be coordinated with daily business operations. Moving significant volumes of panels from the ground to the roof required careful sequencing to ensure safe and efficient progress on the project.
With detailed planning and close coordination with the client, we delivered a high-performing PV system that met the site’s energy objectives and minimised disruption. This project demonstrates the value of precise logistics and strong project management in delivering large-scale renewable energy systems.
What these two projects teach us
These are two different projects, but they emphasise the benefit of working with a solar expert. They also demonstrate how a bespoke solution is required for every installation. A one-size-fits-all approach will not work as each project has its own challenges and opportunities, and effective solar design depends on understanding them both.
The project for Tappers shows the importance of adaptive engineering and the ability to redesign a system quickly when conditions change. Our work for Flexicovers highlights the value of strong planning, structured coordination and expert on-site delivery.
The role of storage in maximising performance
Many of our clients are turning to battery energy storage systems (BESS) to unlock the full potential of their solar PV arrays. Storage enables excess energy to be retained on-site for later use, reducing reliance on the grid and improving the return on investment.
The combination of solar PV and BESS is now considered best practice for both commercial and residential projects as it provides greater self-consumption and long-term energy resilience. For each project, our primary focus is to specify, supply and install fully integrated systems that match each client’s usage patterns and objectives.
Why choosing the right partner matters
Solar installations are only successful when they are designed and delivered by experienced, accredited specialists. Knowledge of MCS standards, SAP requirements, and Part L regulations ensures compliance, while complete control and management of planning, design, installation and optimisation reduces project risks.
Carman manages technical challenges and complex logistics to deliver quality, reliable systems for every project. By handling everything, from early design to handover, we make sure that each renewable installation delivers reliable, long-term performance.
