And, of course, 'they' forgot to mention the Solar Panels use to re-charge the Batteries .... but well done!!

"energy production capacity has increased from 7 kWh to 56 kWh,"

I don't know if the units there are Olympic Pools or Football Fields.
You would need to know how many days it took to generate that power,
to figure something out.

It looks like the things are sprouting.

" 250w each, monocristalinne Bosch cells." <=== power rating assumes a lot of light

"I would say 7 kWh." <=== so the two sets of panels [12x"250W"] do that much "in a normal day"

Preparing yet more panels. On his way to the 56 kWh per day level (summer). It's going to take more than this.

Gee Whiz. I didn't know how to take your post, Paul!! ;-P

On a 30kW day, I make about $2 .... after having spent about $10,000 so >about 500 very very good days just to cover costs.

Wealth might take just a little while .... by which time, I'll need to >replace my panels ..... and then the Battery .... and then ......... ;-P

But, still, just think of all those GHG I've saved the world from. ;-)

I hope the environmental aspect wasn't the main reason you went to all
that expense, 'cos it's all a massive scam:

Search for 'power wall'

err . . . 'DIY powerwal'.

RL

Will do.

The person in the story, may have a powerwall too.

The individual in the story, seems to be on a tear, with regard
to free energy and running his own "electric company". The installation
isn't big enough to be self-sufficient during the winter.
The powerwall charges off mains, instead of using the solar panels.
The powerwall comes with an interface for solar panels, a limited
number of chains of them. But doing an equivalent using used laptop
batteries is a lot cheaper.

But used batteries, besides holding little charge, can lose their charge
fast

You have to grade the batteries before re-use.

Then you deploy them in mixed/matched groups of AH ratings.
You could aim for about 80% of label capacity, for first
commissioning, at < 25% of the initial material cost (new).
Batteries are rarely retired due to their own age - more
frequently it's the device, connectors, software or dumb
user at fault.

Batteries with higher AH will do more work in the parallel
block, and age more quickly, but the mixed blocks will show
similar properties, on avarage. That is the aim.

Expense is in labour, which for DIY projects, is moot.
