Evidence date: 2026-09-21. Limitation: DNA import duty, DGI IVA rate, UTE avoided-import tariff and UTE export tariff are model assumptions pending official lookup (see §6); module price range is sourced from BloombergNEF / InfoLink tier-1 indexes; yield from PVGIS (JRC).
Reference module class: 700 W-class monocrystalline bifacial / TOPCon PV module intended for industrial-rooftop arrays in Uruguay. Tradvolt treats this as an unbranded reference class for the TCO model; specific OEM SKUs are bound to the RFQ and to the OEM datasheets listed in §9. Reference candidates used to ground the price index and datasheet-style limits:
Uruguay's main off-taker, UTE (Administración Nacional de Usinas y Transmisiones Eléctricas), defines technical requirements for grid-connected PV equipment. The standards typically referenced for PV modules, and the issuing body portals, are:
Cert numbers and issuing body (TÜV Rheinland, TÜV SÜD, UL, VDE, JET, Kiwa) must be confirmed against the OEM certificate register at RFQ. Tradvolt does not assert specific certificate numbers on this page.
Inputs below combine module ex-works, ocean freight, insurance, customs, VAT and BoS/BoP typical for an industrial rooftop. Duty and VAT rates are marked PENDING — lookup and must be confirmed against the official portals named in §6. The scenario uses a total installed CapEx of USD 175,000 for the 500 kWp reference (= USD 0.35/Wp, within the §3.1 illustrative low–high band).

Industrial-rooftop sites in Uruguay (Montevideo / Canelones / San José) typically see specific yields in the range 1,400 – 1,700 kWh / kWp / yr depending on tilt, orientation and shading. Indicative inputs:

| Annual degradation | 0.5 % / yr linear after Year 1 | Model assumption consistent with TOPCon 1st-year + linear warranty envelope in Jinko Tiger Neo / Trina Vertex N datasheets |
Annual energy (Year 1) = 500 kWp × 1,550 kWh/kWp = 775,000 kWh/yr.
Self-consumed = 775,000 × 0.70 = 542,500 kWh/yr. Exported = 232,500 kWh/yr.
Net annual benefit (placeholder rates used to show the formula — NOT current UTE prices):
Total CapEx at USD 0.35/Wp × 500 kWp × 1,000 = USD 175,000.
Simple payback = USD 175,000 ÷ USD 78,475/yr ≈ 2.21 years. The scenario model returns the same figure to two decimals and a discounted payback of ≈ 2.53 yr at an 8.00% discount rate over 25 years.

| CapEx (USD/Wp) | 0.28 | 0.35 | 0.42 | Linear: 0.28→1.78 yr; 0.42→2.68 yr |

For the modelled 500 kWp reference case the computed outputs (25-year horizon, 8.00% discount, USD) are: NPV 772,332.41; IRR 0.4629; simple payback 2.21 yr; discounted payback 2.53 yr; LCOE 0.0316 USD/kWh. Year-by-year cash flow is in §7.
Photovoltaic cells and modules are commonly classified under HS heading 8541. The exact 6- or 8-digit national line must be confirmed against the DNA arancelario en línea (see §6).
UTE typically requires IEC 61215 and IEC 61730 evidence for grid-connected PV equipment, with IEC 61701 recommended for coastal sites. Confirm the accepted list and certificate numbers with UTE at the time of procurement.
Payback (years) = Total CapEx ÷ annual net cash flow. Annual net cash flow = (Energy yield × self-consumption share × avoided import price) + (Energy yield × export share × feed-in price) − annual OpEx. All inputs are listed in §5 and labelled ILLUSTRATIVE — NOT A QUOTE.
Not from this page. TCO briefs are orientation only. A binding landed cost requires a live RFQ with quantity, incoterm, destination, cert list and current freight / duty / VAT lookups. Use §8.
Commercial invoice, packing list, bill of lading or AWB, certificate of origin, IEC 61215 and IEC 61730 test certificates, datasheet, and any importer-specific requirements (e.g. UTE grid-approval letter). Confirm the current set with your despachante de aduanas.
