    Octopus Energy Saving Sessions

    With radical reduction in cost of PV panels there will be enough solar farms to make electricity practically valueless on bright summer days. Battery costs are now also reducing fast, so payments for using overpriced home batteries are unlikely to give reasonable investment returns. A home...

    When does V2H charging on a rapid charger become better then grid connection? (Assuming lots of PV+batteries) Or have a generator rather then paying standing charge.

    Powerwall / battery storage: can you share how you use it with UK energy tariffs?

    I was assuming Fogstar Energy 15.5Kwh 48V Battery for £2500 the inverter cost depends on the wattage you want, but a hybred inverter is not much more then a basic PV inverter (if installing PV).

    Powerwall / battery storage: can you share how you use it with UK energy tariffs?

    Can get 2 to 3 times the capacity with Fogstar batteries on a 3rd party inveter for the cost of a PW. Could be much better option if have heatpump and wish to move all electricity usage to ofpeak.

    Long term it would be better if all charging control was var the chargers, but that would require old chargers to be replaced and Octopus to surport all makes of smart chargers. I don't know how many Tesla are connected to chargers Octopus can't control and how that number changing.

    I would like to see 3 rates, with a higher rate between 3pm-7pm and daytime rate being reduced for other times. So people with limited battery capacity use them when it is best for environment. I not convinced its economic for Octopus to reduce ofpeak rate more as so many people are now...

    Hertz in the US discontinueing Tesla's from Fleet

    A rental EV target in 6 years time does not require action for 4 years, a good case can be made that many of the issues will be fixed by others within that time, so no point doing it now if they only care about 6 years time.

    Solar Panels UK - is it worth it?

    I read the FAQ as being their policy now, and the T&Cs as being written so they can change policy if too many people behave in a unhelpful way. For example if 1000s of Tesla powerwalls started to automatically export just before cheap rate.

    They will 1st decide how to load the transporter based on how the cars had been loaded in the ships, then assign the cars based on the cars arriving on each transporter.

    If large battery capacity it needs a lot of PV output to make Flux better then IO. Agile seems to be overpriced compared to night time IO, few nights are cheaper on Agile then IO. It is even worth people with storage heaters (in large home) buying the cheapeat EV so they can run the heaters...
