We had an excellent four months (11/3 to 15/7) generating 2037kWh from our 4kW system. After 13 years. Paid £1559.60 on the FiT. Amazing. 
‘Twas a very good investment. 


Daikin Altherma 3H HT 12kWh ASHP with Mixergy h/w cylinder; 4kW solar PV with Solic 200 electric diverter; Honda e and new Hyundai Ioniq 5 N electric vehicles with Myenergi Zappi mk1 charger

@julianc Our solar PV has produced more this August than either 2023 or 2024 - long may the increases continue! Regards, Toodles.

My system installed in July 2024 has produced 6.4mWh in 2025 so far and produced 2.2mWh in 2024. Details on my Enphase public page here: https://enlighten.enphaseenergy.com/web/uXk45334506/today/graph/months?public=1

@agentgeorge err… Pass! I dunno what caused that! I’ll have to give it some thought. Puzzled Toodles.

I have puzzled over those home consumption figures and though I can’t now recall the ratios of arbitrage for the various price changes over these 3 years nearly, I can only conclude (without peering through all the energy bills to determine the costs per kWh for those different time periods - and my eyesight would be knocked out for the day doing so) that different rates that I would have set in the Tesla app dictated where the solar energy was sent daily. The other factor being that there may well have been some of OE’s ‘savings days’ or whatever that influenced the figures. Sorry not to be more informative on historical information; memory ain’t wot it wos, (did I mention I am 78?😉). Anyway, in case it is of any help to throw some light on the subject, here are the Tesla bar charts over the period

of which I speak. Regards, Toodles.

Further, these bar charts may throw a few more lumens on the matter… Regards, Toodles.
