Does Celtic Freeport designation actually help commercial PV in SA61 / SA62?
Yes - the Celtic Freeport (Milford Haven and Port Talbot) unlocks Enhanced Capital Allowances on qualifying green plant investment within the designated tax sites. On-site PV forms part of the reduced-tax investment envelope for qualifying operators.
Do First Milk / cheese-making processes really suit rooftop PV?
Very well - cheese pasteurisation, cutting, packing, chilling and CIP loads are continuous daytime electrical. Dairy processors across Pembrokeshire regularly deliver 85%+ self-consumption on rooftop PV, driving 5–7 year payback.
Is west-Wales grid capacity really an advantage over the M4 corridor?
Meaningfully yes - SP Manweb's 132 kV Pembrokeshire network has been reinforced substantially to handle Milford Haven generation. Sub-MWp G99 applications with export limitation clear in 10–14 weeks in most cases, and multi-MWp is deliverable subject to network study.
Is Pembrokeshire actually top-band irradiance?
Yes - SA61 / SA62 sits comfortably in the UK 'south' irradiance band at 1,000–1,080 kWh/kWp/year, and the western maritime climate delivers cool operating temperatures that further improve panel efficiency versus the M25 corridor.
