Off-grid photovoltaic power generation without energy storage

What is an off-grid hybrid power system?

A novel off-grid hybrid power system comprised of solar photovoltaic, wind, and hydro energy sources. Appl. Energy 2014, 133, 236–242. [ Google Scholar] [ CrossRef] Segurado, R.; Krajačić, G.; Duić, N.; Alves, L. Increasing the penetration of renewable energy resources in S. Vicente, Cape Verde. Appl. Energy 2011, 88, 466–472.

Why is solar PV a viable solution for off-grid electrification?

Prices of solar installations have dropped by around 90% in the past decade owing to falling prices of panels and batteries, improved efficiency of units and scale-up of production especially in places like China, which makes solar PV a cost-efficient and viable solution for off-grid electrification 4.

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.

Can hybrid grid-connected solar PV power olive plantation?

Hybrid grid-connected solar PV used to a power irrigation system for Olive plantation in Morocco and Portugal by authors in , the central concerned of the study is to assess the environmental impact of the proposed hybrid system as well as the energy potential relative to conventional powering of the irrigation system with PV-diesel generator.

Should off-grid solar expansion be accompanied by energy storage solutions?

This situation is exacerbated by the fact that off-grid solar expansion needs to be accompanied by energy storage solutions. Current energy storage options viable at scale are lithium-ion batteries (LIBs) and lead acid batteries (LABs), with most off-grid providers switching to LIBs as their lifetime costs are lower than LABs.

Do off-grid hybrid electric generation systems reduce fossil fuel consumption?

Our review was focused on 168 articles published between 2002 and 2019 on the use of off-grid hybrid electrical generation systems as a response to the need to decrease consumption of and dependence on fossil fuels through the integration of different nonconventional renewable resources.
