Minigrid

Researchers in Sweden investigated the complex non-linear tradeoffs between capacity expansion costs and reliability levels of off-grid PV mini-grids and found that capacity expansion based solely on cost-minimization may result in several reliability issues.

In the assessment of scenarios for a sustainable and resilient energy transition in isolated systems in the Amazon, a portion of photovoltaic generators should be installed centrally in order to guarantee a central system of high performance, availability and reliability without clearing any further forest areas, while another significant portion of the generators should be installed distributed over rooftops and in agrivoltaic projects.

MySol Grid Zambia, a subsidiary of Engie Energy Access (EEA), has secured $7.5 million of debt from the Facility for Energy Inclusion (FEI) to build 60 minigrids. The projects will provide electricity to more than 40,000 people in rural areas.

Chris Sparkes, lead technician at UK solar installer Solar Fast tells pv magazine simply throwing money at the PV industry will not suffice.

“Productive use of electricity” (PUE) has been the buzzword in the African solar industry for the past two years. The African Solar Industry Association (AFSIA) has prepared a catalog of solar-based PUE solutions for the continent, including a plethora of new solar off-grid and on-grid systems.

India’s Vivasvan Solar has designed a foldable solar structure mounted on a trolley. The system has mechanisms to prevent damage to the panels during transit and is especially useful for agricultural farms.

Germany’s Fraunhofer Institute for Solar Energy Systems (ISE) is demonstrating how a solar-powered refrigeration unit and dryer could be self-sustaining and improve food security in Kenya.

The minigrid space continues to attract a lot of attention from development partners in Africa. Minigrids can actually generate profits, so there is no doubt that commercial finance players will eventually jump on the bandwagon, according to the Africa Solar Industry Association (AFSIA).

Kenya’s government plans to build 137 solar minigrids across remote locations in the East African country. The project received $150 million in funding from the World Bank.

Discovery Battery’s new lithium iron phosphate battery system has a nominal voltage of 51.2 V and a capacity of 100 Ah. Up to six 5.12 kWh battery modules can be stacked in a single enclosure, and up to four enclosures can be connected in parallel for a total capacity of 120 kWh.
