A solar system typically generates DC current which can easily be stored in batteries. However, with the emergence of solar powered isolated grids and stand-alone systems, Direct Current (DC) appliances could become the better alternative. Traditionally electrical appliances run off Alternative Current (AC), since they are designed to be connected to the grid. Appliances and supplies relevant for specific medical interventions and practices.Appliances or product groups needed for the operational environment (i.e.The application of energy, that is derived mainly from renewable resources to create goods and/or services either directly or indirectly for the production of income or value.Energy consuming products that can operate in resource-constrained settings, or that are designed to operate in off-grid energy system, such as low-voltage DC solar home systems or AC/DC mini-grids.Medical Equipment (In the Context of Healthcare Appliances) Infrastructure (In the Context of Healthcare Appliances) Off-Grid Appliances' Related Definitions Table.1: Important Definitions Concept The increasing awareness of the ability and potential of distributed renewable energy systems for powering productive use appliances.The increase in uptake of solar home systems, which are large enough to power household appliances.With accordance to the 2018's off-grid appliances market survey, the off-grid solar market continues to grow rapildly.
Therefore, there is a huge potential for manufactures to produce off-grid appliances based on clean energy, not only for daily use, but also for income generating purposes. Īccess to energy not only improves the quality of life, but also aids in conducting various income generating activities. These households are capable of affording not only simply solar lanterns, but also other appliances such as Solar Home System (SHS). However, there is a growing market for other, significantly more energy intensive, appliances such as TVs, refrigerators, fans and solar pumps.Īccording to GOOGLA, 47 million households in Africa and Asia that are not connected to electricity enjoy an annual income of 3650 – 18250 USD. Currently the most popular off-grid products are small appliances such as solar lanterns and solar lights. The sum spent on off-grid appliances is expected to rise from around 500 million USD today to 4.7 billion USD in 2020.
All of these technologies are outdated, costly and energy inefficient as well as causing negative health and environmental impacts.Īccording to a report from IRENA (2015) some 20 million households have access to electricity through solar home systems, 5 million households through renewables-based mini-grids and 0.8 million households through small wind turbines. In 2014, 27 billion USD were spent in Africa and Asia on lighting and mobile phone charging with kerosene, candles, battery torches or other fossil-fuel powered technologies.
