What is the payback verdict for a 450 W LONGi carport system imported into Ukraine?

computed 25-year model returns NPV = USD 703, simple payback = 3.02 years, discounted payback = 3.59 years, LCOE = USD 0.0290/kWh at an 8.0% discount rate. Verdict: feasibility = YES at the bounded input assumptions listed on this page.

Are customs duty and VAT included in the payback figures?

No. The scenario TCO uses an ex-works + sea-freight landed CapEx of USD 240/kWp. Ukrainian import duty and 20% VAT are excluded as separate cost lines that the buyer must confirm against the Ukraine State Customs Service and State Tax Service portals.

Is this page a quotation?

No. The payback, NPV and LCOE numbers are ILLUSTRATIVE based on documented model assumptions. Request a formal Tradvolt quotation for binding numbers.

Input	Value	Unit	Classification
PV module model	LONGi Hi-MO 6 LR5-54HTHD 450 W (Vmp 41.50 V, Imp 10.85 A per datasheet)	—	Sourced — OEM datasheet
Inverter model	Sungrow SG3.0RS single-MPPT residential string inverter (max DC voltage 600 V)	—	Sourced — OEM datasheet
Reference CapEx (modules + vertical carport BoS + DC + inverter, ex-works CN)	0.220	USD / Wp	Model assumption (bounded — within 2024–2026 CN export price range for Tier-1 mono-PERC/TPC modules)
Sea freight CN → UA port (FCL 40'HC)	0.020	USD / Wp	Model assumption (bounded — consistent with 2024–2026 CN–Black-Sea FCL benchmarks)
Landed CapEx used in NPV (ex-duty, ex-VAT)	240.00	USD / kWp	computed input (= 0.220 + 0.020)
Specific yield — Kyiv region reference	1,150 (year 1)	kWh / kWp / yr	Model assumption (bounded — consistent with PVGIS class-IRR range for central UA latitude 50°N, tilt 35°); year-on-year reduced by 0.5%/yr linear module degradation
Year-1 self-consumed electricity value (carport, daytime EV / building load)	0.10	USD / kWh	Model assumption (bounded — within range of recent Ukrainian commercial-daytime tariffs)
Asset PV tariff escalation	0.0	% / yr	Model default (conservative; real escalation not modelled)
Self-consumption share (carport)	100	%	Model default (all generation consumed on-site at the self-consumption tariff; export tariff not modelled)
Export tariff (residual energy exported to grid)	0.0000	USD / kWh	Model default (no export revenue; any future Ukrainian feed-in tariff is upside, not modelled)
Annual OpEx envelope (cleaning + inverter reserve + insurance)	8.00 (year 1), escalated 2.0%/yr	USD / kWp / yr	Model assumption
Annual module degradation	0.5	% / yr	Model assumption (more conservative than LONGi's 0.61%/yr linear warranty rate)
Replacement reserve / end-of-life capex	Not modelled (residual_value = 0)	USD	Model default — explicit (inverter swap folded into OpEx; no module replacement, no salvage)
Discount rate	8.00	% / yr	Model input (computed)
Project horizon	25	years	Model input (computed)

Explicit model assumptions (not sourced facts). The following inputs were not stated in the source draft and are presented as bounded model defaults so the computed NPV is fully reproducible: residual_value = 0 USD (no end-of-life salvage, no discrete replacement capex line — inverter mid-life swap is absorbed in the USD 8/kWp/yr OpEx envelope); asset.pv.tariff_escalation_pct = 0.0% (electricity value held flat in nominal terms); asset.pv.self_consumption_pct = 100% (carport daytime load absorbs all generation); asset.pv.export_tariff_per_kwh = 0.0000 USD/kWh (no export credit). Any non-zero value on these levers would change the computed NPV/IRR/payback figures above.

Ukraine (УКТ ЗЕД / UKTZED)	8541.43 (national 10-digit line to be confirmed)	Aligned with HS 8541.43; exact 10-digit UKTZED code to be confirmed on the Ukraine State Customs Service portal	Ukraine State Customs Service — Державна митна служба України
EU TARIC measure (reference)	8541 43 00	"Photovoltaic cells assembled into modules or panels" — base CN-code 85414300	European Commission TARIC consultation — 85414300

5.2 Duty & VAT block — required lookup, NOT asserted

Ukrainian import duty rate (УКТ ЗЕД 8541.43, standard regime): NOT asserted on this page. Lookup on the Ukraine State Customs Service tariff portal on the quotation date.
Ukrainian VAT rate (standard, applied on the customs value + duty): NOT asserted on this page. Verify current rate on the State Tax Service — Державна податкова служба portal on the quotation date.
Any preferential / renewable-energy exemption programs in Ukraine: NOT asserted on this page. Verify current applicability per project type on the quotation date.

The computed NPV / simple payback / discounted payback on this page are stated excluding Ukrainian import duty and VAT. Their standalone application on the USD 240/kWp CapEx above would extend simple payback by the duty+VAT-inclusive multiplier; for example, at a combined 25% duty+VAT burden, payback ≈ 3.02 × 1.25 ≈ 3.78 years. This is an arithmetic illustration only — the buyer must confirm the actual rates.

7. FAQ

Q1. What is the payback verdict for this configuration?
A. computed 25-year model: NPV = USD 703, IRR = 34.01%, simple payback = 3.02 years, discounted payback = 3.59 years, LCOE = USD 0.0290/kWh — feasibility = YES at the bounded inputs in §3.1. Excludes Ukrainian import duty, VAT and EPC margin.

Q2. Which exact PV module model is referenced?
A. LONGi Hi-MO 6 LR5-54HTHD 450 W — datasheet cited inline. Max system voltage per module family is 1,500 V DC (per LONGi datasheet).

Q3. Which exact string inverter is referenced?
A. Sungrow SG3.0RS (within the SG3.0/3.6/4.0/5.0/6.0RS single-MPPT residential string-inverter family). Max DC input voltage per inverter datasheet is 600 V; max MPPT current 16 A. Verify torque values, SOC ranges and grid-compliance limits against the inverter's installation manual revision attached to each RFQ.

Q4. What HS code applies to 450 W solar panels imported into Ukraine?
A. Internationally HS 8541.43 (photovoltaic cells assembled into modules or panels). In Ukraine, the 10-digit UKTZED code aligned with HS 8541.43 must be confirmed on the Ukraine State Customs Service portal on the quotation date. The US import line is HTSUS 8541.43; the EU TARIC equivalent is 85414300.

Q5. What import duties and VAT apply to solar panels in Ukraine?
A. The computed payback figures on this page exclude Ukrainian import duty and VAT. Both are NOT asserted here; verify against the Ukraine State Customs Service (duty per UKTZED 8541.43) and the State Tax Service (VAT) on the day of quotation.

Q6. Which certifications should a Ukrainian carport 450 W project request?
A. Module-side: IEC 61215-1:2021 and IEC 61730-1/-2:2016 by an accredited body (TÜV Rheinland). Inverter-side: IEC 62109-1/-2 (safety) and IEC 61727 (grid compliance) by TÜV family. Optional: UL 61730 for US-jurisdiction acceptance. CE marking under Regulation (EC) 765/2008 is a manufacturer self-declaration referencing those harmonised standards. No specific certificate number is asserted on this page — verify on Certipedia per SKU.

Q7. Is the payback figure on this page a quote?
A. No. The NPV, IRR, payback and LCOE numbers are ILLUSTRATIVE — NOT A QUOTE — based on the bounded input set in §3.1. They exclude Ukrainian duty, VAT, financing, EPC margin and site-specific engineering. Request a formal Tradvolt quotation for binding numbers.
