Solar Panels for Factories in Peterborough

Why factory-roof solar pays back in Peterborough

KMM installs commercial solar PV on manufacturing sites with high daytime electrical loads and large clear roof areas across Peterborough and the surrounding Cambridgeshire. Our HQ in Newark-on-Trent sits 60 minutes from your postcode by road, which means a same-week first survey is straightforward. We have run factories solar projects across the UK — the design language is well-established, the engineering decisions are well-rehearsed and the local grid is well-mapped.

The Peterborough factory market

Our commercial work in Peterborough concentrates around Fengate, Lynch Wood, Hampton. Most factories solar enquiries in the area come from operators consuming 200,000-1,800,000 kWh/year, with typical commercial unit rates of 25-31p/kWh. On those tariffs, a sensibly-sized solar PV system displaces 30-55% of total annual consumption and pays back inside 3.5-5 years on continuous-load sites.

System sizes we install on factories

• System range: 80-700kWp typical
• Payback: 3.5-5 years on continuous-load sites (with Annual Investment Allowance (AIA) applied for limited companies)
• Self-consumption profile: Steel-portal factory roofs handle 12-18 kg/m² imposed load. Self-consumption typically 75-90% on 24/5 production lines.
• Common matched load: compressors, CNC, injection moulding, conveyors, HVAC, plate freezers

Grid connection in Peterborough

Peterborough sites typically clear DNO applications inside 8-14 weeks for sub-250kVA G99 installs. G99 standard process — KMM submits as part of project. For sites above 250kVA, KMM designs with G100 export limitation from day one to avoid 12+ month grid offer delays.

Planning and permissions

Roof-mount commercial solar on factories buildings is permitted development under Class J of the General Permitted Development Order — no planning application required. Exceptions: listed buildings, conservation areas and any installation more than 200mm above the existing roof line. Peterborough's planning authority is Peterborough City Council; for unusual buildings we engage their planning department at pre-application stage.

Grants and finance options

Three live finance routes for commercial solar in Cambridgeshire in 2026:

1. CAPEX — you fund and own the system. Best ROI for profit-making limited companies; the Annual Investment Allowance (AIA) can recover up to 25% of capex via corporation tax.
2. Asset finance / lease — 5-10 year fixed monthly payments with full ownership at end of term. Useful for cash-conservative projects.
3. Power Purchase Agreement (PPA) — third-party owns the system; you pay only for the kWh you consume at a tariff well below grid. Zero upfront.

Cambridgeshire has access to specific grant routes — see our grants overview. For ground-mount on agricultural land specifically, regional D2N2 and Midlands Engine business support may apply.

Why a Newark-based installer makes sense for Peterborough factories

• Local presence — our drone-survey crew is on-site within 5 working days from enquiry, not 5 weeks like a national operator
• Drone-led surveys — every project starts with a CAA-compliant drone capture (no ladders, no scaffolding for the survey), 3D model in 48 hours
• One named project manager — same person from survey to commissioning, no call-centre hand-offs
• Honest finance disclosure — every quote shows the published commission and side-by-side comparison of CAPEX vs lease vs PPA
• Tree planted with Woodland Trust for every install
