Engineered for reliability. Designed for performance. Delivered by experts.
At Pensdown — The Electrical People — we deliver fully integrated commercial solar panel installations across the UK. Backed by more than 35 years of experience in electrical infrastructure, we offer a technically grounded approach to solar energy that supports long-term cost savings, energy resilience and net-zero ambitions.
From manufacturers, logistics providers and education trusts, to office developers and agricultural business, we design and install solar PV systems that work for your site, your budget, and future plans. Our solar installations are engineered around your building, electrical systems, and operational needs.
A full design-and-build solar solution
We manage every stage of the process in-house, from the initial feasibility survey through to commissioning, handover, and maintenance. We are solar specialists, working as one team to deliver systems that are safe, compliant and built to last.
We begin with a detailed assessment of your property, energy use, roof space or available land, structural conditions, and switchgear capacity. From here, we design a bespoke PV system.
This includes:
• Panel layout
• Inverters
• Mounting frameworks
• Electrical connection routes
• Battery storage
• Monitoring platforms
• EV charging integration.
Pensdown also takes care of DNO applications, planning conditions (where applicable), structural load analysis, and grid compliance, giving you a single point of contact from start to finish.
What’s included in a commercial solar PV installation?
A typical commercial Pensdown install includes:
• Site-specific design with accurate yield modelling and shading analysis
• Panel selection from trusted Tier 1 manufacturers with 25-year performance warranties
• Inverters, cabling, containment, switchgear integration, and surge protection
• Roof-mount, ground-mount or canopy system installation, including scaffolding and access
• DC & AC wiring, full commissioning, NICEIC certification, and O&M documentation
• Optional battery storage, export limitation, EV charge point integration, or BMS compatibility
• Full digital handover pack including schematics, test reports, manuals and warranty info
All work is carried out by our qualified team, with zero subcontracting and strict adherence to current IET Wiring Regulations, MCS standards, and best practice in commercial solar safety and performance.
Planning permission and compliance support
In most cases, commercial solar panel systems fall under permitted development. This depends on the site’s location, roof type, and local planning conditions. Pensdown will advise full planning permission is requirements. If so, we can manage the application on your behalf, including documentation for structural loads and system visibility.
Understanding system size, cost, and return.
No two systems are the same — but for typical commercial installations, we regularly design systems in the 25kW to 250kW range, depending on energy use, roof space, and budget.
We provide a detailed performance estimate and financial model as part of our proposal, including export values (if applicable), degradation rates, and estimated CO₂ savings. Where battery storage or load shifting is viable, we help you understand how best to use your system to reduce grid reliance and avoid peak tariffs.
Financing and funding
While many grants have closed, various commercial finance options are still available.
These include:
• Asset finance
• Power purchase agreements
• Energy leasing.
Pensdown can advise on the most appropriate option for your business based on cashflow, ownership preference and ROI timescales.
