Langkah desain
1. PV capacity: max(5kWx1.3, 10kWhx1.5/(4hx0.8)) = 6.5 kWp
2. Battery: 10kWh x 1d / 90% DoD / 95% = 15 kWh (16S1P)
3. Battery life: ~8,000 cycles @ 90% DoD
4. String design: 1 strings x ~12 modules (temp-corrected 3-18/string)
5. DC voltage drop: 0.5% (PV1-F 4mm², 30m run)
6. Mounting: tilt 25.9° · row spacing 3.4m
7. Performance ratio (PR): 0.98 soiling x 0.97 mismatch x 0.98 wiring x 0.975 inverter x 0.92 temp = 0.836
8. Inverter: hybrid 5kW
9. LCOE (full-cost): $0.1426/kWh over 25 yr (O&M + WACC + inverter replacement + degradation)
10. Turnkey cost: FOB 3,709 → installed 8,308 (50% soft + 12% landing)
11. Payback / IRR / NPV: 12.2 yr · IRR 5.9% · NPV $-1,415 · DSCR 0.92
Catatan desain
Pricing basis: BOM shows FOB equipment price (ex-works). Economic figures (LCOE/IRR/payback/DSCR) use an estimated turnkey cost that adds typical freight/duty and EPC/installation/soft costs — see Economic basis.
Payback period: ≈ 12.2 yr simple payback at $0.12/kWh tariff (full-cost basis).
Levelized cost (LCOE): $0.1426/kWh full-cost over a 25-year life (O&M + WACC + inverter replacement + module degradation included).
String design: 1 strings × ~12 modules/string — temp-corrected Vmp/Voc stay within the inverter MPPT window ✓
DC voltage drop: ΔU 0.5% < 2% ✓ (4mm² PV1-F, 30m run).
Mounting: Tilt 25.9° optimized for the site latitude; row spacing 3.4m avoids winter shading.
Battery life: 15 kWh at 90% DoD ≈ 8,000 cycles (~22 yr of daily cycling).
Note: Final system design must be confirmed by a licensed local engineer against site conditions and local grid codes.
Economic basis (indicative): Turnkey cost = FOB equipment + interconnection + landing (freight/duty 12%) + EPC/installation/BOS/soft costs (50% of installed). Pre-tax, year-1 DSCR, indicative only — not a bankable financing model.
