They don't provide any backup, they are purely to make your grid power-meter spinn slower or sometimes even feed back into the grid (when allowed).
The cheaper versions do make economic sense in countries with high electricity costs for home consumers, but its not a "great investment".
Yeah. It seems like a cool idea, but I can't quite understand the ecenomics being it.
I can see it being used as a "trial run" for people considering going solar or off grid in the future, it can be a safe first step, as the parts of these kits would integrate with the whole home systems sold by these same companies.
You just hook it up and your electricity bill will be lower next month. Not sure what is so complicated about that :) I don't think most people are considering it a trial run or plan to upgrade if they live in a small rented apartment with only a balcony.
Valid points. Plus you can bring it with you if you ever move, definitely a huge bonus.
And if the life cycle is 10 years, it will end up paying for itself terms of energy savings.
