Subject is relevant and interesting, as I was exploring the increased polarisation, and reached similar conclusions. It hit me hard, so I’ll check it out later.

tnx4 sharing

nicely done.

In the USA there are silly rules that you can only get 120% capacity of your last years worth grid consumption as solar installed.

Yes , I can see how that impacts the process. indeed checking the rules and doing some prior info digging is essential.

It’s also important to check whether solar overcacity is worthwhile in the UsA. Her3 it is not( anymore).

I believe it would attribute to cheaper of free energy and to more peace. I am agreeing with you.

And I imagined a all encompassing " worldgrid" across all continents and islands. We did it with phone networks, now we should do energy.

Need to wire the whole world. Let’s go.

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.

You need to find out;

1. energy usage
2. insulation options and materials
3. costs /benefits
4. energy contracts and energy incentives.
5. check out current physical electricity wiring and fuses in the house
6. 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. 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.

(Ed: layout)

Basically why the grid exists to begin with

Agreed this is the best option. Economy of scales and our consumers wishes should dictate the Grids plan to incorporate cheap energy ( and emergency) storages.

And, also like you said, change your energy life style and insulate your house wherever you can.

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, battery, would already create more independence (at around € 3K to € 10 K in Europe) .
