Berlin-based start-up Solarworx specializes in the supply of modular, off-grid, solar-plus-storage solutions.
The novel methodology can be used for 71 countries located across ‘sun belt’ areas of east Asia, South Asia, and sub-Saharan Africa. The model relies on 2014 and 2015 geo-referenced datasets in various formats and spatial resolutions, as well as on a population dataset based on global human settlements (GHSL) and World Bank national-level estimates of electrification.
Off-grid PV has become a much more viable solution than diesel power generators to bring electricity to Russia’s remotest regions. Furthermore, solar-plus-storage is able to deliver with no interruption 24 hours per day and seven days per week, while fuel availability means diesel power can only ensure between four and seven hours per day.
Sony lab and LF Energy are developing a new approach to enable peer-to-peer microgrid energy trading, so remote communities can store and distribute energy without connecting to large-scale power stations or distribution grids.
The expedition to Manaslu Peak (8,163m) in Nepal, led by Alex Txikon, will not consume a single liter of fossil fuels thanks to two portable photovoltaic installations. The initiative is being promoted by Eki, a foundation created by Spanish solar company Solarpack and supported by the Basque Energy Agency (EVE).
Researchers in Finland have demonstrated the technical feasibility of an off-grid residential PV system combined with short-term battery storage and seasonal hydrogen storage. The proposed model is applicable only to northern climates, as higher levels of solar radiation in southern locations would mean a reduced need for seasonal storage. It was tested in an existing single-family house in Finland with a 21 kW rooftop array and a ground source 6 kW heat pump.
The U.S.-based Mercy Corps has opened a call for expressions of interest in the installation of mini-grids at three refugee camps on the Somali border.
Bboxx rents out offgrid PV systems and TVs to rural villagers across Africa. Customers can buy electricity under a mobile-based pay-as-you-go model.
The Indian government plans to set up of a 10 MW grid-connected solar project and a range of unique off-grid applications – including solar trees and solar drinking water kiosks – to meet all the energy requirements of town situated next to a 13th-century Hindu temple.
