Portable solar
Portable solar options come in a variety of styles to
suit a variety of needs. Many portable items exist which make use of
solar technology to fulfill their purposes. For instance, a variety
of solar powered handheld lights can charge during the day for nightly
use.
Perhaps the most useful options are portable solar panels. These can
be used to charge or power a variety of electronics, from MP3 players
to laptops to speaker systems. Panels may fold-up, roll-up, or be built
into such things as bags or clothing.
Portable solar options do not necessarily involve creating electricity.
Some exist simply to harness heat. An example of this is a portable
solar shower, which can be taken on camping trips to provide a nice
hot shower regardless of location. Another example is a portable solar
oven which can heat food through the concentration of solar thermal
energy.
