stand-alone small solar electric systems

solar modules

A stand-alone small solar electric or photovoltaic (PV) system operates off-grid – in other words, it isn't connected to a electricity distribution grid operated by a utility.


A stand-alone PV system makes sense if any of the following apply:


  • You live in a remote location where it's more cost effective than extending a power line to a grid.

  • You're considering a hybrid electric system – one that uses both a PV (solar electric) system and a small wind electric system.

  • You need minimal amounts of power; e.g., for irrigation control equipment and remote sensors.

    Anyone can take advantage of outdoor solar lighting – a stand-alone PV application.
