 All systems include one or more solar modules of different sizes and various appliances. Frequently used categories are '''multi-user systems (MUSs) or PV mini-grids''', '''[[Solar Home Systems (SHS)|solar home systems (SHSs)]]''' and&nbsp;'''PicoPV systems'''.
-PicoPV systems are small independent plug-and-play appliances providing light and/or additional electrical services, like charging mobile phones and mp3 players as wel as powering radios,&nbsp;small televisions, small fans etc. These systems in any case can replace candles and kerosene lamps.

 The distinction between SHS and PicoPV is not&nbsp;an absolute one. Fundamentally, since the respective names refer to different aspects&nbsp;that don't exclude one another: very small systems (picoPV) just as well can serve a household. On the other hand since the range of products classically called "pico PV" (small capacity plug-and-play devices) is ever- expanding and now (2015) includes plug-and-play devices with capacities that historically were considered the lower end of SHS.

-*[[Solar Cells and Modules|Solar Panel:]] The PV panels for the lights are mostly made of polycrystalline or mono-crystalline silicon. The peakpower of the solar panel ranges from 0.3 Wp for a solar lantern with an integrated panel up to nowadays 80 Wp for&nbsp;the bigger plug-and play systems.

 Many models of PicoPV systems also allow for the operation of other small electric devices such as a ''small radio, small loudspeakers'', or a ''MP3-player''. In general, the size of the module and the storage capacity of the battery determine the range of electric appliances which can be connected to the system. If required even a ''small TV'' or a ''little fridge'' can be operated. One example is the seven inch solar LCD Colour TV of Free Energy Europe which consumes less than 10 W . In addition, various standard plugs USB-ports are also on the rise. They facilitate the operation of a huge range of small USB-devices like for example small fans.
