Africa off-grid

Phaesun and Solar Cooling Engineering have developed a PV-powered cold room for small-scale farmers in Africa. The solution, which has been installed at a farm in Kenya, includes a 2.8 kW solar array and vapor compression heat pumps.

Zola Electric’s new lithium iron phosphate battery system charges from solar and the grid and can power AC and DC appliances. It has a nominal voltage of 12.8 V and a nominal capacity of 50 Ah.

South Africa scientists have developed an integrated, solar-powered heat pump and refrigerator for use by food vendors in sub-Saharan Africa. The dual system is powered by two 90 W solar modules and repurposes waste heat.

Berlin-based Boreal Light has developed water desalination tech powered by PV for off-grid applications. The solution uses 460 W solar panels from Chinese module manufacturer DAH Solar and produces clean water from direct seawater at a cost of €0.50 ($0.54)/m3.

An international consortium led by Powergrids plans to invest $100 million in three off-grid solar plants intended to power the cities of Gemena, Bumba, and Isiro, which are located in the country’s northern region and currently have no connection to the country’s power network.

Almost 60% of Nigeria’s population currently has access to electricity. But this breaks down as 78% in cities and urban areas, and just 39% in rural communities. The Rural Electrification Agency (REA), established by the government as part of electricity sector reforms in 2005, is tasked with bridging this gap and bringing reliable energy supply to the most remote parts of Nigeria. pv magazine spoke with REA CEO Ahmad Salihijo Ahmad about the organization’s strategy and recent progress, as well as the challenges that remain for rural electrification in Nigeria and the role of PV technology.

A study has attempted to provide detailed analysis of the beneficial impact off-grid renewables, led by solar, are having on people in the world’s least developed countries.

The microgrid utility has raised enough capital from Shell New Energies to deploy systems across sub-Saharan Africa.
