This paper presents an integrated techno-economic assessment of a 25.92 MWp gridconnected bifacial solar photovoltaic (PV) plant planned at Ballards Valley, St. Mary,Jamaica. A PVsyst 7.3.1 simulation, a tentative bill of quantities (BOQ), a baseline 598-daydelivery schedule and a 20-year power purchase agreement (PPA) cash-flow model arecombined to quantify energy yield, levelized cost of electricity (LCOE), investmentreturns and debt capacity. The plant (57,600 bifacial 450 Wp modules, 128 string inverters,fixed tilt of 30°) is predicted to inject 43.59 GWh in its first year, equivalent to a specificyield of 1,685 kWh/kWp and a performance ratio of 83.6%; the P50, P75 and P90 annualestimates are 43.81, 43.20 and 42.65 GWh. At a capital cost of US$0.72/Wdc, a flat PPAtariff of US$85/MWh and the conservative P90 yield, the unlevered pre-tax project IRR is15.9% and the consistently discounted LCOE is US$56/MWh at an 8.03% discount rate, sothe break-even tariff lies 34% below the contract price. With 80% debt at 6% repaid overseven years, the minimum debt service coverage ratio (DSCR) is 1.19 and the equity IRR is27.3% before tax. Sensitivity analysis shows that capital cost and tariff dominate projectreturns, while degradation and O&M cost are second-order. A reconciliation with theproject's early-stage screening workbook shows that inconsistent discounting and ahard-coded outlay had understated the IRR (7.4%) and LCOE (US$31/MWh), illustratingthe importance of internally consistent financial screening
