Solar Panels and Battery Packs
Whilst the price of Solar energy isn't yet cheap enough to make it more attractive than pulling power from the grid, it's certainly now useful enough for situations where grid power isn't an option. My usage so far has been when camping and also when sailing - times when connecting to the grid isn't possible and having your own supply becomes more essential, read the info here with that in mind.

The best way to use a solar panel is with a battery pack to use as an energy store. It relieves much of the inconvenience of being tethered to a solar panel for charging and helps you overcome the unreliability of the sun. Plus, they're a handy emergency source of power for the times when you're not carrying the solar panel with you;
