Off-Grid Solar Appliances, a range of energy-efficient electrical appliances that are appropriate for both off-grid or weak-grid areas1 where low-capacity power systems
are not suitable for the use of conventional appliances. These devices are typically compatible with a DC-powered system and should be more energy-efficient than traditional counterparts. In this report, our focus is onTVs, fans, refrigeration units, and solar water pumps. At this early stage of data collection
for appliances, only a small subset of all available appliances are considered, as only the solar-powered appliances are accounted for. Our scope is further narrowed to focus on those appliances most suitable for purchase
by individual customers on a household or micro-enterprise level. In the case of solar water pumps, this means they must be less than 3kW and solar-powered, while for refrigeration, large commercial scale walk-in units are not considered.
The distinction between Cash and PAYGo Sales Sales are split into two categories, based on whether the products are sold to a customer either:a. As a cash sale, in a single transaction to the customer. Note that this category also typically includes products purchased via tender by governments and humanitarian agencies.b. On a Pay-as-you-go (PAYGo) basis, when the customer pays for the product in installments over time or pays for use of the product as
a service. This includes products sold by distributed energy service companies (DESCOs) and microfinance institutions (MFIs), as well as those sold as lease-to-own.Following the confidentiality rule, the split in sales volumes is shown for any single data point where at least three separate manufacturers have reported data for both cash and PAYGo products. Otherwise, when only one of the two payment categories passes this confidentiality rule, only the combined total is shown.
Off-Grid Solar Lighting Products
This segment consists of systems that include
a solar panel, a battery,f and at least one light source. This means that products that are sold as components such as individual panels, lights, batteries or mobile phone chargers, are not included.Data has been grouped into product categories to present sales in a segmented manner that provides the most value and information to the market.
The categories of all products with less than 11Wp solar module capacity is determined by the services provided by the product in question. An example of this would be the number of light points and the possibility of mobile charging. Each of these categories is represented by an indicative wattage range of PV module that is typical for most products providing these services. Panel wattage in watt-peak (Wp) is used to categorize off-grid solar lighting products with solar modules of 11 Wp and above. The definitions of these categories are presented in Table 4.The level of energy access these off-grid solar lighting products provide is shown using the multi-tier framework for measuring energy access. This framework was developed by the World Bank’s Energy Sector Management Assistance Program (ESMAP)6 under the Sustainable Energy for All initiative.
Off-Grid Solar Appliances
This segment of the report features a range of off-grid solar appliances (TVs, fans, refrigeration units, and water pumps) sold targeting customers living in off- or weak-grid areas.At this early stage of data collection for appliances, only a small subset of all available appliances are considered, as only the solar-powered appliances are accounted for. Our scope is further narrowed to focus on those appliances most suitable for purchase by individual customers on a household or micro-enterprise level. In the case of solar water pumps, this means they must be less than 3 kW and solar-powered, while for refrigeration, large commercial scale walk-in units are not considered. Companies and sector experts assessed howbest to categorize and present the findings in this report to offer the greatest possible clarity for each appliance type and its sub-categories. The Global LEAP Awards’ categorization for refrigerators and solar water pumps was adopted,as it was designed to recognize high standards
of technical performance, energy efficiency, and innovation specifically for off-grid appropriate appliances. Using this product categorization means the data in this report is presented as clearly and consistently as possible across the sector. In future rounds, we may review the solar water pumps categorization and the terminology of the refrigeration units’ section, due to the continued growth and evolution in these appliance areas.Two out of four appliance types were segmented not only by their size (e.g. the diameter in inches for the fans), but also by the typology of products (e.g. table fans vs. ceiling fans). The categorization below was adopted as a way of future-proofing and we accept that for now, most of these single categories will not be shown, as the three data point rule hides all the data points where less than three responses have been collected.
