  • I’m very ignorant on this subject, but couldn’t you just sell excess to grid and get it back for a minimal markup?

    Sure, but it depends on the incentives in your country. Afaik, excess energy could be sold, but you’ll have to checkout your local incentives and energy suppliers for specifics. In most parts of Europe, the are scaling down the prices for excess energy. Therefore, battery systems are being forwarded in some cases as sort of solution for solar panels maintaining like ca. 80% +? integrity efficiency over 20 to 30 years.

    For example, I read that in The Netherlands the solar panel market has crashed completely or is crashing. Note here that saturation of the market ( many existing solar panels) can also cause that.

    Then , after doing that, check your kwh usage, and buy solars according to that.

    Hope this is helpful, but seems you need to go outthere and do some exploration on the topic.

    1. energy usage
    2. insulation options and materials 3 costs /benefits 4.energy contracts and enegy incentives.
    3. check out current phisical electricity wiring and fuses
    4. DIY or professional? 7 . budget etc

    TLDR: dont buy solarpanels if you want to be rich. And buy them according and after you’ve done everything possible to insulate your house, whether in the colder or warmer climates. The efficiency, added value, and comfort reached by insulation outweighs everything else.

  • How big a battery would we need in order to be completely self-sufficient?

    Exactly. Haven’t read all details of the link,so I react your comment, and have immersed myself a bit in this earlier.

    You need to change your way of thinking and energy usage. Start with your daily energy supply and then change your energy consumption pattern to day time use Then, with for example a dynamic energy contract or if you can spare solar energy, buy or store cheap electricity in your storage ( battery ). The energy management system ( charge / uncharge and which cells) is very important.

    Also, realize that battery life is tied to charge cycles and need replacing like every 10 years when talking about the better quality Lithium battery . Sodium systems could and maybe should be used in parallel, if you want more storage, safety and longevity (20 years).

    It is yet all quite expensive, though imo having a half day reserve ( like 5 - 10 kwh) at ( around € 3K to € 10 K in Europe) battery, would already create more independence.

    Who aRe you?

    (Γνῶθι σεαυτόν, gnōthi seauton)

    It’s like the famous question: " If a tree falls in the forrest, but you are not around, does the falling tree still makes a sound?

    A fundamental question now in quantum theories, that they still can’t answer afaik
