My understanding is there is less of a need for massive grid upgrades in this model due to the use of storage. Rather than having to be able to distribute peak loads from solar, requiring a larger connection, you can smooth out the supply a

Thanks for the answers. I used to work for a EV smart charging company (Kaluza) that ran a V2G trial. V2G was financial success for the users, but I always thought the wall box was a potential blocker. I don't think the 2kW output is a

Very interesting - I did not know this was possible. A few questions: 1. Does the solar inverter do away with the need for a V2G or V2H unit? 2. What are the limitations vs a dedicated V2G/H unit? 3. Is generator input on your solar in

I only found out about the WELLBY due to this report. I don't have the time or expertise to evaluate it, so I'm interested in why you find it "iffy"?

Apologies, the 2029 figure was the annual install amount. Total estimated installed amount is 400 GWh. Solar Power Europe says "780 GWh by 2030 to fully support the transition". From the page[1]: > By 2029, the report anticipat

To provide some numbers on the storage side of things. On European battery storage [1]: * 2024 - 21.9 GWh installed. * 2025 - 29.7 GWh predicted to be installed. * 2029 - Between 66.6 GWh and 183 GWh to be installed for 2029. Total capacity
