Photovoltaics, commonly referred to as PV, is the direct generation of electricity from light.

'Off-Grid' PV - more correctly referred to as stand-alone or autonomous PV systems – in basic terms, are automatic battery chargers.

  • PV modules convert daylight into electricity – which is then stored in a battery.

  • Electricity in the battery is available throughout the night, periods of bad weather and through the seasons.

  • The energy in the battery can be used for an extremely broad range of services.


Daylight goes in one end, electricity comes out the other – a PV based system ensuring continuous operation, 24 hours a day, 365 days a year. 

Generic value

  • No fuel required

  • very low operational cost

  • no external connections

  • No emissions

  • Very reliable (no moving parts)

  • Silent

  • low (unskilled) maintenance

  • Automatic operation (for fixed location systems)


When designed and deployed correctly, energy services enabled by autonomous PV are typically the lowest ownership cost option.

Stand-alone PV solutions can be personal or national, urban or rural, portable or fixed infrastructure.

From calculators to satellites, proven value exists at every scale for individuals, organisations and nations.

Systems can enable hundreds of services such as personal lighting and mobile phone charging, electrical devices for schools, hospitals and businesses, and national communications or entertainment networks. In fact, there is a PV value proposition for every person on the planet.

There are more applications of stand-alone PV than there are apps for smartphones.
