Museum Solar 150 kWp LatAm — Use-Case & TCO

Verdict (base case): A 150 kWp rooftop PV system at a Latin American cultural museum returns NPV = USD 344,424.69, simple payback = 2.30 years, discounted payback = 2.64 years, IRR = 44.50 %, LCOE = 0.0455 USD/kWh over a 25-year horizon at an 8.00 % real discount rate — GO. Equipment family: Jinko Tiger Neo 550 Wp monocrystalline modules paired with three Sungrow SG50CX string inverters, on a K2 Systems low-ballast flat-roof rail kit. Evidence date: 2026-01-15. Limitation: figures are computed outputs of TradVolt's scenario TCO model for the named equipment family and the scenario inputs below; they are not a customs, engineering, or financial recommendation. Module/inverter datasheet manuals are JS-rendered on OEM sites — exact manual revision is confirmed at RFQ.
