Customer case history:

  • Marcos in Hathern, Leicestershire
  • Had a 7kwp solar PV system with a Powerwall 2 installed in 2022
  • His annual electrical data for 2023 was:
  • House consumption – 3169kwh
  • Solar generation – 6288kwh
  • Powerwall released – 1094kwh
  • Imported electricity – 365kwh @24p/kwh
  • Exported power sold to Octopus – 3221kwh @15p/kwh
  • Nett account position at the end of 2023 £395 in credit

“ I am so happy with my Powerwall 2 and PV system from Carbon Legacy. I am not a big consumer using only 3,169kwh in 2023. But with the PV/Tesla Powerwall system reducing my imported power to only 365kwh and the Octopus “Outgoing Export tariff” I ended up £395 in credit at the end of 2023. I could not ask for more!”
