Stand alone solar lighting (often referred to as ‘off grid’) is a completely self contained and free standing independent system with its own energy generation means (solar panel), and energy storage capacity (battery). The advantage of this is that no cabling or trenching is necessary.
Stand alone requires a battery in each pole, and with correct battery and solar panel sizing, will keep operating through prolonged bad weather
Should the lighting project be remote and a long distance from the grid, stand alone solar lighting is often a superior option, as not having to trenching and cabling can save considerable money up front.
