Solar for Businesses in Pembrokeshire

For businesses across Pembrokeshire, rising electricity costs, rural grid constraints, and increasing sustainability expectations are having a direct impact on profitability and long-term planning. Solar for Businesses in Pembrokeshire provides a practical, commercially proven way to reduce energy costs while strengthening operational resilience.


At Carbon Zero Renewables, we design and install commercial solar PV and commercial solar battery systems for organisations operating across Pembrokeshire — from agricultural enterprises and food production facilities to industrial units, offices, retail premises, and hospitality businesses.

Our focus is simple: deliver solar systems that perform reliably, generate measurable savings, and remain commercially valuable for decades.


Why Commercial Solar Works Particularly Well in Pembrokeshire


Pembrokeshire’s mix of rural, industrial, and coastal business environments makes it especially well suited to commercial solar.

Key local advantages include:

  • Large roof areas and land availability
  • High daytime electricity usage in agriculture and industry
  • Rural grid capacity limitations
  • Growing pressure to demonstrate sustainability


For many Pembrokeshire businesses, solar is no longer a “green upgrade” — it is a strategic infrastructure investment.

Commercial Solar PV Systems for Pembrokeshire Businesses


A commercial solar PV system generates electricity on-site, allowing businesses to reduce reliance on grid imports and stabilise long-term energy costs.


Commercial systems are engineered around:

  • Verified consumption data
  • Operating hours and load profiles
  • Roof structure or land availability
  • Grid connection and export limits


Many Pembrokeshire businesses achieve self-consumption rates of 70–80%, meaning the majority of generated electricity is used directly within the business rather than exported at lower rates.

The Cost & ROI of Commercial Solar

The cost of solar for businesses varies depending on system size, roof type, and installation complexity. But falling panel prices and improved efficiency mean solar now offers a strong return on investment for all sectors—from hospitality and farming to retail and light industry.

System Size (kWp) Estimated Cost (inc. VAT) Ideal For Estimated Annual Savings/Income Typical Payback Period
10kW £11,500 - £14,000 Small shops, farm offices, cafes £1,800 - £2,300 5 - 7 years
30kW £27,000 - £34,000 Guesthouses, workshops, schools £5,500 - £7,000 4 - 6 years
50kW £44,000 - £53,000 Hotels, factories, leisure centres £9,000 - £11,500 4 - 6 years
100kW+ £78,000+ Large industrial units, food processors £18,000+ 3 - 5 years

Commercial Solar Batteries: Strengthening Energy Control


Adding commercial solar batteries enables businesses to store excess generation and use it later, improving returns and resilience.


Battery storage helps Pembrokeshire businesses:

  • Reduce peak electricity charges
  • Manage grid constraints
  • Improve energy security
  • Increase solar self-consumption


Carbon Zero Renewables designs scalable battery systems that can expand as operational needs change.
