I know that there are bigger ones that you can power your laptop from, and actually keep working from it, but they are very expensive for me. So I thought – maybe a small one (that is used for ipods, psp, mobiles etc) would work (not for running your laptop directly from it, but leaving it to charge during the day, and using it in the evening – this is when I use it most) Is it going to work, do you think?
cheers

I use a small solar panel to send this e-mail from Botswana. It powers a laptop , the sat-internet and 5 or so energy saving bulbs 5-6 hours per day. I costs around 150 US. I think its big compared to what you are taking about (50w). Its still cheap
Its made by Shell and BP the small ones, tailor made for consumers in the west might be more expensive.
The catch is it provides 12v which I first need to store in a 12V battery, then invert to 220v using an inverter about the size of a laptop powersuply. From this 220 supply I can now use any charger I like, phone , I pod,light bulbs and laptop.
The standard little ones provides a voltage eg 7.4 V that is tailor made for that device eg Nokia phone. Some might even cater for many different ones.
Mine total cost around 250 USD . But you can’t put it in your handbag.
It suits my lifestyle, I live and work in isolated places, if the sun don’t shine I fall back on the car battery. Its also not that green because of the 12V lead/acid battery. But then all batteries are not green. The lead can be recycled.
The solar panel needs to be baby sitted , moved around to stay in the sun. Might work for me but not for you.
yes why not if it could caves you television to play why
