Solar panels
Portable panels can be integrated into electronic devices and objects (for example, there is a solar refrigerator, oven or table). Portable panels can be integrated in electronic devices (for example, a solar fridge, oven or table). They can also be used standalone as portable fold out modules.
Power banks and photovoltaic panels can be used together to store energy. Sometimes, the “buffer battery” is part of a solar module.
Remember that solar charging efficiency is heavily dependent on weather, season and climate zone. The characteristics can be difficult to meet, especially when the panel is used on the move (on a back pack, in a boat or on the camel’s back).
