Is a 2 kilowatt solar system enough to power a home? Is the cost reasonable for the system?

Similar questions: kilowatt solar system power home cost reasonable.

Depends on the size of house and its electrical energy needs. Also a "2 kilowatt" solar system usually means that the system is capable, when brand new, and with the panels freshly washed, of putting out 2 kilowatts DC when the sun is at right angles to the panels. Average that out over 24 hours, and cloudy days and after storing in a battery and then conversion to AC it's more like a 150-watt system, which is barely enough for a garden shed.

If the house has AC and electric heat, you need a system that's at least 20 times as large.

Again, the question of where you live is very important. If you live in Western Oregon or Washington it will not return the cost ever. If you live in Phoenix or Sacramento it could pencil out.

There might be times that you need more, but it could provide a significant part of what youu need and it might work for some. The significant items are refrigerationa nd AC in the summer. Other than that the new light bulbs and fans will not use that much.

But you need to give some numbers for a cost evaluation.

If you want to heat with solar power, which I do not recommend, one would have ways to heat liquids and store it in massive storage units in the home - not with solar electricity.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
