IRENA estimates that some 133 million people accessed lighting and other electricity services using of-grid renewable energy solutions in 2016. This includes about 100 million using solar lights (<11 watts), 24 million using solar home systems (>11 watts) and at least 9 million connected to a mini-grid (Figure 1).
Off-grid renewable energy systems are not connected to the utility electrical grid. These systems have no wires bringing electricity on or taking electricity from the site. Instead, all of the electricity used at this site is generated on site by renewable energy sources such as the wind, sun, water, and/or the use of biomass.

This recommendation suggests moving beyond ''energy for fiat money'' model of off-grid energy economy towards ''energy for in-kind things'' economic structures. Such an approach could assist in the development of new energy exchange models that can function without the need for fiat money and utilize locally available goods and
In this study, off-grid renewable energy systems are defined as systems in which both electricity as well as heating and cooling demands are met by renewable energy. As shown in the subsequent results section, the review focuses on systems with 100% renewable energy but also discusses off-grid systems that import fossil fuels and

The generation of excess electricity beyond the storage capacity is a major challenge for energy efficiency in off-grid hybrid renewable energy systems (HRESs). This problem is more severe for high renewable penetration systems, which rely on intermittent solar and wind resources to supply demands with unstable peaks.
