Annual consumption: 2,700 kWh (Ofgem typical medium household). Winter 60% / Summer 40%.
System: 4 x Storm 178W flexible solar panels (TopCon monocrystalline), total 0.71 kWp. Microinverter: Hoymiles HMS-800W-2T (800 VA, 2 MPPT, 96.7% peak efficiency).
Orientation: Modelled at 90-degree vertical mounting (typical for fence or balcony railing). This is a conservative estimate. Tilting panels to a more favourable angle will increase generation.
Year 1 generation: 525 kWh (estimated for London, based on typical balcony/fence mounting).
Panel degradation: 2% in year 1, 0.7%/year thereafter (conservative estimate for flexible ETFE panels).
Seasonal generation split: Winter 28% / Summer 72% (Thames region profile).
Self-consumption rate: 100% year-round. System output is well below household demand, so all generation is consumed on-site.
Electricity tariff: 30 p/kWh peak (average smart time-of-use daytime rate), 7 p/kWh off-peak (overnight rate), 3% annual inflation.
Battery: Hoymiles HiBattery 1920 AC (HB-1920-AC-SV), 1.92 kWh usable capacity, LiFePO4 cells, AC-coupled, 87% round-trip efficiency, IP66, 6,000+ cycle life, 10-year warranty.
Battery arbitrage: Off-peak grid charging at overnight rates, peak discharge during daytime. 365 days per year at full capacity (1.92 kWh). Solar generation is consumed directly by the household and does not charge the battery, leaving full battery capacity available for grid arbitrage year-round. Battery operates at 800W maximum output, sufficient to offset household base load during peak hours.
87% round-trip efficiency.
Battery arbitrage savings assume the customer is on a smart time-of-use tariff with off-peak overnight rates. Actual returns may be higher or lower than projected
depending on tariff availability and usage patterns. All figures are estimates based on the assumptions above and should not be considered as guaranteed
returns.
