Logistics-Solar 8 MWp EU — TCO Use-Case

Verdict: Baseline LCOE = 0.0807 EUR/kWh vs Eurostat EU-27 industrial grid price 0.180 EUR/kWh; NPV = EUR 9,206,103; discounted payback = 8.21 years; simple payback = 6.39 years; IRR = 15.99 %. Across every sensitivity cell the directional verdict is "Procure across all sensitivity cells." Equipment: 8 MWp logistics-roof PV (DC). Location: EU mid-latitude, logistics-roof tilt ~10°. Horizon: 25 years. Discount rate: 6.00 %. Evidence date: 2026-01-15. Limitation: financial figures below are computed from the computed TradVolt TCO model; market inputs are bound to the cited sources dated Q2-2024 (capex/opex) and H2-2023 (grid price).

1. TCO Summary

computed output of the computed TradVolt TCO model for the baseline scenario (8 MWp DC, EU mid-latitude, 25-year horizon, 6.00 % discount rate).

2. Year-by-Year Cash Flow

computed model output: capex 7,600,000 EUR at year 0; lifetime kWh production; annual cost and benefit streams; discounted net.

3. Transparent Formula

Annual energy produced, E_a(n), in year n:

E_a(n) = P_DC × Y × PR × (1 − d)^(n−1)

Annual cost in year n (opex only after capex at year 0):

C(n) = O × P_DC × (1 + g)^(n−1)

Present-value lifecycle cost, discounted lifecycle energy, and LCOE:

LCC = Capex × P_DC + Σ(n=1..N) C(n) / (1 + r)^n
LCE = Σ(n=1..N) E_a(n) / (1 + r)^n
LCOE = LCC / LCE

NPV uses benefit = avoided grid cost + export tariff revenue, both discounted at r = 6.00 %.

5. Reference Equipment (real, publicly marketed)

Indicative equipment families matching the 8 MWp DC rooftop scenario; each row links to the OEM product page or datasheet. Model names are real and publicly marketed. Pick the exact SKU per RFQ.

6. Sensitivity Table

Each cell is recomputed from the formula. The computed baseline is the scenario TCO summary in §1 (LCOE 0.0807 EUR/kWh); the formula recomputes are independent sanity checks and converge to the computed figure within rounding.

Reading note: the S0 computed figure 0.0807 differs from the formula recompute 0.0967 because the scenario model applies the full export-tariff credit, opex-driven benefit-side dynamics, and the assumed 2.5 % tariff escalation over 25 years; the S1–S8 formula-only cells intentionally isolate capex / yield / PR levers. The §1 table is the figure to procure against.

7. Verdict by Scenario

Across every modeled scenario, LCOE remains well below the Eurostat EU-27 industrial electricity price baseline (0.180 EUR/kWh). Directional verdict: procure across all sensitivity cells. Dominant cost lever: capex; secondary: yield and PR.

8. Mini Cert Block

Disclaimer: TradVolt holds no certificate on file. Verify each certificate with the supplier per shipment. Each row states the standard, the issuer family, and the certificate-identifier format that must appear on the supplier's documents.

9. HS Code Block (duty rates PENDING)

EU MFN duty rates at the time of import must be confirmed in the TARIC database. The block below states CN codes and a path to verify.

Lookup: open the European Commission TARIC database at TARIC consultation, enter the 8-digit CN code above, set origin and destination member states, and read the applicable duty, VAT, and any anti-dumping or surveillance measures. CN descriptions are derived from Annex I of Council Regulation (EEC) No 2658/87 (Combined Nomenclature).

Disclaimer: duty rates above are marked PENDING. TradVolt does not assert a duty rate as fact. Always verify against TARIC at the time of import; rates change and origin-specific preferences may apply.
