Equipment installed
- 27 x Solfit 425W dual-glass all-black solar panels (in-roof GSE system)
- 1 x SigEnergy Sigenstor 8kW single-phase hybrid inverter
- 2 x SigEnergy 8.76kWh batteries
- 1 x SigEnergy HomePro SP-F single-phase gateway
Solar Panels Generation
Typical UK generation on a good day:
- Summer: up to 45–55kWh per day
- Spring / Autumn: around 20–35kWh per day
- Winter: around 5–10kWh per day
Battery:- 17.52kWh of total usable battery storage
Estimated Electricity Coverage (Typical Household Usage)
Approximate self-sufficiency levels (will vary by usage):
- Summer: 80–95% of electricity covered
- Spring / Autumn: 50–70% covered
- Winter: 20–40% covered
Even in winter, batteries and smart tariffs still reduce costs significantly.
The Sigenergy Gateway transforms the system into a true smart energy hub, by providing seamless backup power during grid outages and boasting an automatic changeover with no manual intervention once the system detects grid loss.
Flexible tariffs for smarter savings
Charging the batteries overnight on off-peak tariffs allows:
- Lower-cost energy to be stored and used at peak times instead
- Full usage of your solar install, batteries will still be used to their maximum capacity even when solar generation is down to 20-40%
- Consistent savings even during low-solar winter months
