Solar photovoltaic off-grid power generation trends

Are PV and wind-power technologies a viable option for off-grid hybrid systems?

In terms of trends, the studies show a mature development of PV and wind-power technology for off-grid hybrid systems independent of the latitude, which is preferred as they are proven and accessible methods.

Where does off-grid renewable power come from?

Off-grid renewable power can come from a variety of sources, ranging from large isolated power grids to solar lights and solar home systems.

How big is off-grid solar PV?

In the last decade (2008–18), the globally installed capacity of off-grid solar PV has grown more than tenfold, from roughly 0.25 GW in 2008, to almost 3 GW in 2018. Off-grid solar PV is a key technology for achieving full energy access and achieving the Sustainable Development Goals.

How can solar PV be adapted to off-grid applications?

Thanks to its modular and distributed nature, solar PV can be adapted to a wide range of off-grid applications and to local conditions, ranging from lanterns to household systems to village-powering mini-grids.

Is off-grid electricity production growing?

Off-grid electricity production from renewables, although largely unrecorded in most countries, is believed to be expanding rapidly. By combining information from surveys, administrative data and desk research, the International Renewable Energy Agency (IRENA) has attempted to illuminate major trends in off-grid renewable energy deployment.

How has the solar PV industry evolved in recent years?

The evolution of the solar PV industry so far has been remarkable, with several milestones achieved in recent years in terms of installations (including off-grid), cost reductions and technological advancements, as well as establishment of key solar energy associations (Figure 5).
