Solar Panels for Factories in Essex
Factories are the ideal solar candidate: high daytime electricity consumption that perfectly matches solar generation, delivering self-consumption rates of 60-80% or higher — without any battery storage.

Why Solar Works for Factories
Manufacturing operations consume the most electricity during production hours — precisely when solar panels generate the most power. This alignment means factories achieve the highest self-consumption rates of any commercial building type, typically 60-80% without battery storage. Every kilowatt-hour consumed on-site saves the full retail electricity rate (22-27p/kWh), rather than the much lower export rate (5-8p/kWh).
Essex has approximately 4,000 manufacturing companies employing over 40,000 people. The county's industrial heartland centres on Basildon, which has the highest concentration of industrial space in Essex. Burnt Mills Industrial Estate, Pipps Hill (home to Amazon and Argos distribution), and the Cranes Farm Road corridor (CNH Industrial, FedEx) represent a massive concentration of manufacturing energy demand.
Ford's Dunton Research & Development Centre has already installed a 5.2MWp solar array — one of the largest commercial installations in Essex — demonstrating the viability and scale possible for factory operations.
Factory roofs are typically robust steel structures designed to carry significant loads, making them well-suited to solar panel installation. Pitched metal roofs use direct-fix mounting brackets, while flat sections use ballasted systems.
Typical System Specifications
Roof-mount on steel structure, 50kW-250kW
| Size | Annual Generation | Estimated Savings | Payback |
|---|---|---|---|
| 50kW | 45,000 kWh/yr | £8,000-£12,000/yr | 4-5 years |
| 100kW | 90,000 kWh/yr | £17,000-£25,500/yr | 4-5 years |
| 250kW | 225,000 kWh/yr | £42,500-£63,750/yr | 4-6 years |
Financial Benefits
The Annual Investment Allowance provides 100% tax relief on solar investments up to £1M, effectively reducing costs by 25% at current corporation tax rates. Factories with high self-consumption rates see the fastest payback periods — often under 4 years. The 10-year business rates exemption on new rooftop solar further improves returns.
Factories Solar in Essex
Basildon has the highest concentration of industrial space in Essex. Burnt Mills Industrial Estate, Pipps Hill Retail Park (Amazon, Argos distribution), Cranes Farm Road (CNH Industrial, FedEx), and Festival Business Park are all prime candidates. Ford's Dunton R&D Centre already has a 5.2MWp solar installation. Essex has approximately 4,000 manufacturing companies employing 40,000+ people.
Key Benefit
Factories consume most electricity during production hours, perfectly matching solar generation for self-consumption rates of 60-80% — maximising savings without battery storage.

A typical 100kW factory system generates around 90,000 kWh/year. With 70% self-consumption at 24p/kWh, annual savings reach £15,000-£20,000. Payback is typically 4-5 years, with 20+ years of savings thereafter.
No. Solar installation takes place on the roof and at the distribution board. We schedule electrical connections during planned shutdowns or outside core hours. Production continues uninterrupted.
Often yes. Asbestos cement roofing is common on older Essex factories and does not automatically prevent solar installation. We arrange a licensed asbestos condition survey before any work. Where the material is stable and undisturbed, solar can often be installed without disturbing it. Where the roof needs replacing, we can coordinate a combined re-roofing and solar programme that may qualify for the same AIA tax relief treatment.
Excess generation is exported to the grid under the Smart Export Guarantee, earning 5-8p/kWh. Battery storage can also store energy for use when production resumes, maximising self-consumption.
Solar panels are a standard building improvement. We provide all certification (MCS, NAPIT) required by insurers. Most commercial policies cover solar as standard building fabric.
