No it won't catch on until its longer lived. It needs batteries to be more
robust and long lived.

I often wonder if solar panels have been accelerated life tested? I know
they are used on spacecraft, but one has to assume these are pretty
ruggedised and reliable devices, as you won't get many service engineers out
there.

Isn't it just conventional battery technology packaged in a different way?
The cost effectiveness will depend on the initial cost of the device (£3K)
and how long before you have to replace it (a 1000 charge/discharge cycles
in 3 years?)

I see no quoted figures for efficiency.

The success of the project seems to be dependant on _Government_ subsidies
for green energy and the falling price of Lithium. In the UK there are no
Government subsidies - just the 15% green/social tax on all our
gas/electricity bills.
