Renewable energy statistics just keep topping each other. Solar power is getting cheaper. Battery storage capacity is getting better. And wind farms are getting bigger.
2019 saw the world’s biggest (at the time) offshore wind farm come online, as well as construction of the biggest offshore wind farm in the US off the coast of Atlantic City.
But a new figure blows all of these out of the water. Last week, British renewable energy developer SSE announced construction of Dogger Bank Wind Farm off the eastern coast of England in the North Sea.
With a capacity of 3.6 gigawatts (GW), Dogger Bank will be three times bigger than the world’s biggest existing wind farm, the nearby 1.2 GW Hornsea One.
Located near a seaside town called Ulrome, which is 195 miles north of London, Dogger Bank will have three separate sites—Creyke Beck A, Creyke Beck B, and Teesside A—each with a 1.2 GW capacity, and construction is slated to take two years.
The project is a collaboration between SSE and Equinor, a Norwegian energy company.

Domestic solar power installed cost should be around $30000 + $1 /watt. If you are really* using 50Kwh / day you'll need at least 10Kw.
Deep-cycle lead-acid is about $150 /Kwh, but you need to double it and only use half the capacity if you want them to last, so call it $300 /Kwh.
How much storage you need depends on how tolerant you are to load shifting.
* The average household only uses about 25Kwh /day.

oops. That should have been $3000 + $1/watt

Hmm, that is way cheaper than what Ive been seeing. What is the catch? I was looking at this: http://offgridpowerboom.com/goal-zero-yeti-3000-review/ [offgridpowerboom.com]
It's a 3 kWh generator (ie, special battery) for $3k.

That Yeti is cool for camping, but is not what you would connect to fixed solar/battery installation.
Deep cycle AGM lead-acid batteries : 12V x 100Ah = (approx) 1Kwh

Might of been a little low on the panels, or maybe Home Depot is a bit high :
