Thread: Nuclear

There is a lot of very useful information being posted here by I suspect, people who are more than qualified to comment. Thanks for sharing the benefit of your knowledge.

Would anyone be prepared to hazard a guess at the size & cost of a off grid stand alone power system to provide for the average household? This needs to be big enough so that the way power is consumed from the stand alone system is the same as being connected to the grid.

How much solar & battery power? Do you add some wind power to the system? Do you need a standby generator?

That would depend on the consumer, A hunter's hut or a decadent mansion ?
A 5 kw system with a reasonable battery bank would require most people to think about how they use their power .
Cost is basically related to quality & size .
I would consider a gen backup as essential .

I did say average household.

This is what I’d be using. My company has just built a 1 GW gas fired plant in Texas and they are working on these zero emissions design. As interim why not use gas?

Depending on consumption, to go off the grid maybe about 6.5kW of solar panels and 6kW of batteries with total cost from about $16k depending on the batteries chosen. We already have solar hot water.

To stay on the grid and eliminate power bills you might need about 6-7kW of solar panels wired to power the house first and export the excess to the grid during the daytime, earning a rebate of about 20 c/kW hour.

All those figures are only estimates depending on variables, of course.

No need for a generator.
I have looked at small wind generators similar to those on yachts in the $2-3k range. Main benefit is at night to replace some power drained from the batteries to run the house.
