Frequently Asked Questions
How much does commercial solar cost in Northamptonshire?
Commercial solar in Northamptonshire costs £750–£1,050 per kWp installed in 2026. A 100kWp system on a Northampton warehouse or Wellingborough factory costs £75,000–£105,000 and generates approximately 97,000 kWh/year (970 kWh/kWp). At 30p/kWh with 70% self-consumption, annual savings are £20,370. Payback is 3–4.5 years, falling to 2.5–3.5 years after Annual Investment Allowance at 25% CT rate.
Who is the DNO for Northamptonshire?
Northamptonshire is served by National Grid Electricity Distribution (NGED), covering all NN postcodes. For commercial solar with grid export above 3.68kW AC per phase, a G99 application to NGED is required. Standard processing is 65 working days. The A45 and M1 logistics corridor in Northamptonshire has seen significant new commercial development, and some areas may require NGED capacity pre-checks for large systems.
Why is Northamptonshire good for commercial solar?
Northamptonshire is one of the UK's largest logistics and distribution hubs — the Golden Triangle (M1/A14/A5 junction) hosts Amazon, DHL, DPD and hundreds of 3PL operators with massive flat-roof distribution centres ideal for 250kWp–2MWp solar installations. The county's manufacturing heritage (footwear, food, automotive) also gives good commercial solar demand. Central England location gives solid irradiance (~970 kWh/kWp) with competitive installation costs.
