Import Solar Panel 700W from China to Switzerland — Industrial Rooftop TCO

Answer first — illustrative, not a quote. For a 100 kWp industrial rooftop in Switzerland using 700W-class Chinese-OEM monocrystalline modules, the computed 25-year TCO model returns NPV ≈ USD 125,699, IRR ≈ 30.99 %, simple payback ≈ 3.30 years, discounted payback ≈ 3.97 years, and LCOE ≈ USD 0.0484/kWh. Equipment class: 700W monocrystalline PV module (candidate OEM families: LONGi Hi-MO 7, Jinko Tiger Neo, Trina Vertex N) plus 100 kW three-phase string inverter (candidate: Sungrow SG100CX or Huawei SUN2000-100KTL). Location: Swiss Plateau industrial rooftop, illustrative site (PVGIS-class irradiance). Horizon: 25 years. Evidence date: 2026-09-21. Limitation: figures are an scenario model output; duty/VAT, irradiance, self-consumption ratio and any preferential programme must be confirmed against BAZG Tares, PVGIS and the buyer's DSO before commitment.

1. Equipment Class and OEM Candidates (700W Module + 100 kW Inverter)

The 700W-class monocrystalline PV module is a real, currently-produced product family. TradVolt sources against the following candidate OEM models (each with a public datasheet and IECEE cert record). The matched inverter is a real 100 kW three-phase string inverter. Buyer substitution with any IEC 61215 / IEC 61730 certified equivalent is permitted in the RFQ.

Cert numbers (IEC 61215, IEC 61730, IEC 62109) are issued by accredited bodies and verifiable in the IECEE database. The final BOM must show the actual cert number issued to the specific model/batch; this is gathered at RFQ stage, not assumed here.

2. CapEx — Module + Vertical BoS (ex-duty/VAT)

Illustrative ex-duty CapEx = USD 0.497/Wp. Duty and import VAT (NRP 8.1% standard rate) are NOT included in the computed cash flow above and must be added at customs declaration against the BAZG Tares entry.

3. OpEx — Annual Operating Costs

4. Production, Tariff and Revenue Model

5. Explicit Bounded Assumptions (not facts)

6. Payback & Sensitivity

Sensitivity rows recompute yields × tariff − OpEx from first principles against the computed cash flow, then re-derive payback and NPV against the 8 % discount rate and 25-year horizon. They reconcile to the TCO summary within rounding.

7. Compliance & Certifications

IECEE cert verification is performed at RFQ stage using the issuing CB's certificate number; no cert number is asserted on this page because the buyer has not yet selected a specific OEM model.

8. Duty-Stack & Tariff Block (Switzerland)

Switzerland's free-trade and customs competence sits with SECO (State Secretariat for Economic Affairs) for policy and BAZG (Federal Office for Customs and Border Security) for operational tariff classification. Any specific rate cited above is illustrative and must be reconfirmed at the time of quotation.

10. FAQ

What HS code applies to 700W solar panels imported into Switzerland?

Photovoltaic modules fall under HS 8541.43 in the Swiss Tares database (BAZG). The applicable MFN duty rate and any preferential treatment for CN origin under the Switzerland–China FTA must be confirmed at the time of quotation.

Which certifications are required for grid-tied industrial rooftop PV in Switzerland?

IEC 61215 (crystalline module design qualification) and IEC 61730 (module safety) are the baseline. The inverter must carry IEC 62109-1/-2. Grid connection follows the VSE/AES reference rules and the local DSO's connection conditions.

What is the illustrative payback and NPV for a 100 kWp 700W industrial rooftop array in CH?

ILLUSTRATIVE — NOT A QUOTE. Under the scenario model assumptions (USD 0.18/W module, USD 0.317/W vertical BoS, 16% capacity factor, blended tariff USD 0.115/kWh effective, 8% discount, 25-year horizon, 0.5%/yr degradation, 1.5%/yr tariff escalation, 30% self-consumption at retail offset): NPV ≈ USD 125,699, IRR ≈ 30.99 %, simple payback ≈ 3.30 years, discounted payback ≈ 3.97 years, LCOE ≈ USD 0.0484/kWh.

Is the vertical BoS included in the TCO?

Yes. Inverter, racking, cabling, combiner, monitoring, installation labour and commissioning are itemised so the buyer can substitute OEM quotes. The illustrative BoS line totals USD 31,700 ex-duty/VAT.

Does Switzerland apply import duty on solar panels from China?

Modules enter under HS 8541.43. Switzerland applies MFN duty plus 8.1 % import VAT (NRP). Switzerland is not in the EU, so EU CBAM and EU-TCA rules do not apply. Any anti-dumping/countervailing measures on CN-origin PV modules, and any preferential under the Switzerland–China FTA, must be confirmed at the BAZG Tares portal before shipment.

Can TradVolt match me to a certified Chinese OEM?

Yes. Submit the RFQ form above with quantity, incoterm and target certs. We return a FOB/CIF landed quote with matched datasheets and IEC 61215 / 61730 cert numbers within 48 hours, sourced from CN OEMs holding valid certificates for the candidate families listed in §1.

All cost inputs are model assumptions; irradiance is illustrative; self-consumption and tariff escalation are model assumptions. Duty/VAT rates must be confirmed against the BAZG Tares portal at quote date; certification must be confirmed against IECEE records and the OEM's Declaration of Conformity; grid connection must be confirmed with the local DSO.
