Use case: villa-hybrid-backup-8kw | Vertical: LFP / Solar BoS | Trade lane: CN → IT | Evidence date: 2026-09-22 | Equipment: Sungrow SH8.0RT (8 kW hybrid inverter) + Pylontech US5000 (9.6 kWh LFP, 48 V) | Limitation: EU MFN duty and Italian VAT are PENDING live lookup on EU TARIC and are excluded from the CapEx below.
Verdict (answer-first). Over a 10-year horizon at an 8.00 % discount rate, the modelled villa deployment produces an NPV of EUR 6,188.85, an IRR of 31.00 %, a simple payback of 3.08 years, a discounted payback of 3.66 years, and an LCOE of EUR 0.0945/kWh. Headline undiscounted benefit is EUR 16,605.20 against total undiscounted cost of EUR 4,850.00. These numbers are computed from this page's own scenario (Sungrow SH8.0RT + Pylontech US5000, central-Italy PVGIS yield, 55 % self-consumption, 0.28 EUR/kWh import, 0.10 EUR/kWh export, 6 kWp PV pairing) and exclude EU MFN duty and Italian VAT, both of which must be looked up live on EU TARIC and ADM at RFQ time. Duty/VAT caveat: PENDING live lookup on https://ec.europa.eu/taxation_customs/dds2/taric/taric_consultation.jsp?Lang=en and the ADM portal — see §5.

Annual PV generation = 6 kWp × 1,300 kWh/kWp/yr = 7,800 kWh/yr
Self-consumed energy = 7,800 × 55 % = 4,290 kWh/yr
Exported energy = 7,800 − 4,290 = 3,510 kWh/yr
Annual savings = 4,290 × 0.28 + 3,510 × 0.10 = 1,201.20 + 351.00 = 1,552.20 EUR/yr
