It surprises me that people aren't raving about this. It's small, thin, light well designed, with extensions for just about everything you could need it for. But most importantly, it seems to really work.
Straight from the box today, I charged my laptop. This was towards sunset, when the sun was low, through glass, and without any consideration about optimal positioning. The results were fantastic. So I can't wait to see its potential over the next few weeks, in a good position, in strong sunlight.
I guess I'm not saving the planet, but considering how many mp3 players/laptops/cameras, etc... that need charging, I think it could make a real difference with this panel.
Because of its design, I think I should be able to rig some kind of semi-permanent set-up, but also take it away, to charge on the go. So the aim is to completely cut out mains electricity for these small appliances, which I think is feasible, with a little planning about how/when to charge (though this might mean buying the battery that goes with this panel, in order to store for night/cloudy periods.).
So we'll just have to wait and see how it performs in winter... But, for now, couldn't be happier with this.
