Abstract Experience shows Africans in rural settings value outcomes (e.g., light, TV, refrigeration, productive use of power, water pumping and irrigation, agri-processing) & not simply access to electricity. Because of the high rates of poverty in rural Africa and the cultural inhibition to saving, access to energy is of no value unless appliances and equipment are included in a PAYG or leasing plan. This project provides the R&D to create a complete range of high-efficiency, appliances (generally DC), and equipment that match these PAYG controlled Solar/battery Power Systems (SPS).The concept is design to create jobs, improve incomes, and expand the local economy. This will focus on the productive use of power that increases the productivity and value add for rural smallholders and micro-enterprises. An innovative business concept of leasing (with no deposit) Businesses-in-a-BoxTM (BinaB) has been developed. Each BinaB will comprise of 3 aspects:Physical hardware comprising high-efficiency DC end-use equipment coupled to a modular and upgradeable PAYG solar power system sized to meet the required duty cycle and sharing commonality of parts.A business model demonstrating economic viability both for African business and the Distributed Energy Services Company (Africa Power and SAfP) (DESCO) leasing the systemsSupport services including as appropriate: training, business expertise (e.g. agronomist for drip feed irrigation), access to relevant business inputs, complete on-going maintenance, and refurbishment.The plan is to source, adapt and/or develop equipment that meets the specification and test for viability. Prototypes will be deployed to Tanzania to test the business model and develop the required service packages in conjunction with relevant business partners. This will involve running equipment tests and economic models in multiple iterations of size and ways of use, product improvements, with the expectation that we will produce working PROTOTYPES for 4-6 businesses systems, with full business model evaluations for both customers and the DESCO. Around 50-100 BETA test units will be manufactured and field trialed and reported with sufficiently innovative designs be protected by patents, design rights, copyright, and/or trademarks.In addition, the range of solar power systems (SPS) will be extended. A unique feature of these series is that systems can be field upgraded by adding multiple PV panels, expanding the size of the box, inserting a larger battery, and approximately every second upgrade adding daughter control boards to handle the increased power draw and currents. This keeps the small systems low cost, whilst having full capability at larger systems with maximum re-use of the smaller systems components. Systems will be designed and tested with 50-100 BETA trial systems for each of the sizes developed. Furthermore, the PAYG system will have new apps and software packages delivered with full specification & user manual documents.As well asthe BinaB systems, upgradable domestic solar home systems, making use of the extended range of SPS, will be developed with lower costs by sourcing efficient, cheap but robust appliances (small fridges, fans, lights, mosquito repellents), low maintenance batteries and denser packaging to reduce shipping costs. Prototypes will be manufactured in different size configurations (100-200) for BETA field trials in Tanzania. All the above new products will increase the revenue and profitability (and Energy Access in SSA) of the DESCO's in Africa including Africa Power's subsidiary companies including increased sales of its PAYG software and support services. Africa Power (UK) sources all the products for its subsidiaries with appropriate transfer pricing, thus increasing revenue and profits in UK. Cost reductions can be used to increase sales by attracting a poorer demographic or increase profits or a combination thereof
