With a rising chorus of voices calling for more solar industry recruits to perform the energy transition, Nigeria already has a skilled base of PV engineers and, with a little help filling the few gaps they have in their knowledge, the nation can step into the breach immediately, as Testimony Gabe-Oji, chief technology officer for Abuja-based installer Green Energy Spectrum, explains.
Solar energy is not only key to the energy transition and the reduction of greenhouse gas emissions; it is also a way to empower remote and rural communities that are isolated from easy access to electricity. Across the globe, distributed solar solutions are being implemented to improve the well-being of individuals, communities, and businesses by providing access to clean, affordable energy. Huawei technology is at the heart of many of these solutions, as the following case studies from Africa and the Middle East demonstrate.
Former start-up Husk, which originally based its business on renewables powered by rice industry waste products, has agreed to develop seven solar-plus-storage mini-grids across rural communities in Nasarawa state.
The ARM-Harith Cities and Climate Transition Fund will feature public and private finance, according to the joint venture behind it.
U.S.-owned, Nairobi-based mini-grid developer PowerGen has already rolled out seven local solar networks in the West African country, funded by equity investors who will recoup their cash when all 28 systems are sold to CrossBoundary Energy Access.
A report commissioned by EU lender the EIB has dismissed the role solar mini-grids can play in achieving universal electrification by 2030 and signaled distribution to individual households should be the way forward, including sales to the residents of UN refugee camps in East Africa.
State-owned China Xinhua Power Development has booked a $53 million discount on seven solar farms as developer Kongsun seeks to pay down debts, and Canadian Solar has landed a 45 MWh energy storage contract in Colombia.
With ‘shovel-ready’ projects across India, Africa and Latin America in line for a mix of grants, cheap loans, equity investment and financial guarantees from this year, the two bodies hope to trigger $20 billion in total funding and bring reliable power to a billion people.
An international research team has designed a residential solar-plus-storage system based on gravity. The system was built with a solar power generator, a bulk booster charge controller, an inverter, a solenoid device, a deep cycle battery, a pulley block, a geared motor, a microcontroller, and wire ropes. Its creators said the system is ideal for regions with high solar radiation. They found that, due to its high electrical requirements, the system needs to rely on high-power solar modules with an output of over 500 W.
Energy efficiency, electrification of heating and transport, and the provision of clean cooking facilities are all going in the wrong direction as the Covid crisis deprived millions in sub-Saharan Africa of electricity use, according to a report by the IEA, IRENA, WHO, World Bank and UN Statistics Division.
