What about a rechargeable battery pack?
I thought about a Pi in a birdhouse, and cables were going to be a problem,
but I did find a 4AA battery pack could work

kind regards

Hi All
I have recently set up one of my raspberry pis and a cheap webcam to film
some flowers growing on my window sill however going to plug them in last
night I realised the nearest plug socket is miles away.
It isn't feasible to move the flowers so thought I would take a look at
solar methods and thought it best to ask you all in case any of you had any
experience with it or thoughts.
Any help would be great
David

Hi John
Thought that may have been the case, will just have to run more cables
around I think. Isn't too much of an issue but the room is already starting
to look like PC World with the amount of computers in it already :-)

Hi David,
I wouldn't bother with a solar charger - in my experience they don't charge
as quickly as they discharge. The pi itself draws 350mA without a network
load going on, and the webcam can pull a further 0.5A depending on how it
works... You're looking at nearly a 1A supply to be safe there.
If you really can't run power to it (could you not attach an extension lead
to skirting boards and/or run it over door frames etc), then maybe you'd be
better off with some kind of high-capacity SLA or similar, and a 5v
regulator from that... You could then 'float' that with a solar panel, and
may have better luck.
The other issue with solar chargers is that a lot of them refuse to both
charge and discharge at the same time...
Just my ?0.02.
John
