Solar for a Net Zero Home

How do I make my home net zero?

A net zero home generates as much clean energy as it consumes over a year. For UK homes, the path: (1) Reduce demand: insulate (loft + walls + floor), LED lighting, efficient appliances. (2) Electrify heating: air source heat pump (COP 3-4) + smart thermostat. (3) Generate: 6-8kW solar panels (15-20 panels). (4) Store: 10-13kWh battery for evening self-use. (5) Offset transport: EV charged from solar. Total cost: £15,000-£25,000 (after BUS grant). Annual energy cost: £200-£500 (vs £2,500-£4,000 for a conventional home). True net zero = your solar generates ≥ your total electricity consumption over 12 months.
