Pontardawe and Swansea Valley SMEs face the same core solar finance decision that all Welsh commercial operators encounter: outright purchase, a Power Purchase Agreement (PPA), or grant-assisted outright purchase through Ynni Cymru. The right answer depends on business cashflow, tax position and appetite for capital commitment.
The base case: 50 kWp Pontardawe Industrial Estate
The SA8 irradiation baseline is 950 kWh/kWp. A 50 kWp system generates 47,500 kWh annually. At 73% self-consumption on a typical light-manufacturing SME, year-one electricity savings are approximately £9,375. Export income adds approximately £1,539. Total year-one benefit: approximately £10,914. Capex for a 50 kWp standard industrial rooftop at Pontardawe: approximately £43,000 to £47,000.
Option 1: outright purchase with Annual Investment Allowance
AIA allows 100% of capital cost to be deducted against taxable profit in the installation year, providing a 25% tax credit on the full capex. Post-tax capex after AIA relief: approximately £32,250 to £35,250. Post-tax payback at £10,914 per year: approximately 3.0 to 3.2 years. The business owns the asset from day one.
Option 2: Ynni Cymru grant plus outright purchase
A £15,000 Ynni Cymru grant reducing effective capex to £28,000 to £32,000, and AIA tax relief on the net expenditure, produces post-grant post-tax payback of approximately 1.9 to 2.2 years. For businesses that qualify, Ynni Cymru is the most capital-efficient route. FLD co-ordinates survey and proposal preparation to align with programme application windows. Welsh-medium documentation is available for SA8 Welsh-speaking business clients.
Option 3: Power Purchase Agreement
A solar PPA for a Pontardawe SME involves a developer funding the installation at zero upfront capital. The business purchases the electricity at a contracted rate — typically 12p to 18p/kWh, below the 27p grid import rate — for 10 to 25 years. Annual saving versus grid-only: approximately £4,161. The trade-off is lower lifetime benefit: 62% less than outright ownership annually, in exchange for zero capital commitment. Best suited to limited-capital businesses or tenanted premises.
Option 4: commercial loan
At a 5% to 6% commercial loan rate over 7 years, a £43,000 installation costs approximately £690 per month in repayment. At £10,914 per year benefit (£910 per month), the installation is cash-positive from month one. Loan cleared in year 7; full ownership thereafter. FLD works with commercial finance brokers in SA8 and can provide finance comparisons alongside installation quotations.
