SolaFin2Go (Solar Finance 2 Go)

Lead Research Organisation: University of Ulster
Department Name: Sch of Built Environment

Abstract

More than 600 million people in sub-Saharan Africa live without access to electricity and 90% of the population directly burn solid fuel for cooking, boiling water, lighting and heating. Significant issues exist in the continued lack of access to proper energy supply giving rise to detrimental socio-economic conditions, poor health and well being and local/global environmental concerns, exacerbated by population growth and urbanisation.

The SolaFin2Go project will address the challenge of providing standalone solar systems to make available cost effective and affordable access to electricity and thermal hot water for off-grid households in sub-Saharan Africa. The objective is to test the feasibility of 'entry level' technological solutions combining novel PV and solar thermal technologies financed through improved business PAYG models (enabled by the innovative FinTech platform through Mobile, Cloud and Blockchain technologies) that fit with household/community circumstances to provide basic electrification and hot water. Combining the partner technologies, resources and knowledge in this study has the potential to create a viable, cost effective off grid standalone solar solution to meet many of the challenges identified by the Sustainable Energy for All (SE4All) initiative and directly relates to the Botswana Off Grid Plan and Energy Efficiencies plan. This unique project combines traditional PV systems with battery storage and solar thermal technologies packaged together under an energy, payment and customer management platform that has customer relationship at the heart of the finance model and also has significant potential to add to economic momentum in rural communities and to Transform Energy Access (TEA) for all.

Ulster University and SolaForm Ltd (a Northern Ireland start up spinout with an innovative near-market solar thermal product offering) have teamed up with dpSun/KRD Global Ltd (Poland/UK based PV Company with experience in microgrids) to combine their expertise to develop unique technology driven solar home solution/s for the Botswana market. EmPowered (Pty) Botswana has many years of experience in the Botswana energy and business markets. EmPowered (Pty) Botswana (Fintech solution provider) is supported by Stanbic Bank (as part of the EU WiSE Projects submission) and Barclays Bank. Combining the technologies, resources and knowledge of the partners in this study has the potential to create a viable, cost effective off grid standalone solar solution.

Planned Impact

The SolaFin2Go project will address the challenge of providing standalone solar systems for available cost effective and affordable access to electricity and hot water for off-grid households in sub-Saharan Africa. The objective is to test the feasibility of 'entry level' technological solutions combining PV, solar thermal (with storage and control) financed through improved business PAYG models (enabled by the innovative FinTech platform through Mobile, Cloud and Blockchain technologies) that fit with household and community circumstances.

This project will bring together UK and African academics and industry partners to undertake R&D of the SolaFin2Go system, which will address the 3 fundamental elements of the energy trilemma: cost, emissions and security of supply in SADC countries. The deployment of the system in a typical traditional dwelling in rural Botswana will permit monitoring of the performance of SolaFin2Go on a targeted end user and serve as a realistic, in-situ example for many local community stakeholders to see the applicability of the system for distributed communities in SADC countries. The partners will seek to maximise the impact of this research with the academic community, government and industry, including working with local SMEs that can produce the various services and components using locally available materials and resource. This will build local capacity and go a long way in ensuring the economic sustainability of SolaFin2Go. The benefits the project will accrue to energy professionals, manufacturers, installation contractors and utility companies. The project will have a direct impact on the following beneficiaries

Academia: The system will further the scientific understanding of thermal 'diodicity' and PV module/laminate fabrication techniques. This work will be of interest to those working in solar heat transfer, PCMs and vacuum technologies, PV fabrication and operation/storage. The FinTech platform will be of interest to those working in energy finance and management, telecommunications, IT, big data and storage. The wider socio-context to the work will be of interest to many involved in the social implications of energy access and financial empowerment in rural/peri-rural communities in sub-Saharan Africa. The project will enrich existing knowledge/understanding of the technologies through the cross-disciplinary collaboration, facilitating knowledge transfer between the UK and African partners.

Industry: Various industrial sectors, in the UK and Africa could benefit from this research; they include SMEs' with interests in solar technologies and energy-finance management. They will be actively sought out, invited to examine material produced in the project dissemination activities.

Policy Makers: This project will demonstrate the potential for independent solar technologies combined with an innovative energy, payment and customer management platform for harnessing and supplying solar energy locally as well as the economic and environmental benefits of utilising the abundant solar resource. This improved understanding will be highly beneficial to policy makers. The consortium will highlight the benefits and findings of this study to policymakers in the UK and Africa through dissemination activities.

Society: SolaFin2Go will reduce the use of fossil fuel and greenhouse gas emissions It will support financing and empowerment of the 'unbankable'. Local community structures will develop through accelerating the transition to modern energy services in remote and rural areas, while also offering the co-benefits of healthy living, improvement of living standards, contributing to climate change, as well as positive effects on income growth and distributive equity in communities. The project will also enhance the electrification of communities which will improve communications and facilitate greater quality and availability of education.
 
Description The main aim of the award was to "test the feasibility of 'entry level' technological solutions combining novel PV and solar thermal technologies financed through improved business PAYG models (enabled by the innovative FinTech platform through Mobile, Cloud and Blockchain technologies) that fit with household/community circumstances to provide basic electrification and hot water". The study has successfully achieved this aim through completion of the following work:
• A review of Sub-Saharan African household energy demands was undertaken and used to establish a design target for the daily electricity and hot water outputs of an entry-level stand-alone solar energy system.
• Design targets were used together with climatic data to establish a rational approach for the sizing of photovoltaic and thermal solar collectors; and battery and hot water energy storage elements.
• Prototype entry-level stand-alone solar energy systems were designed and a trial prototype was tested in the laboratory under solar simulated conditions to characterise performance, validate operation, and enable design optimisation.
• Three optimised system prototypes were fabricated, shipped to Botswana, and installed for field trials at a primary school and two nearby houses in an off-grid rural village where residents rely on petrol generators and firewood for their energy.
• A remote data communications system based on LoRaWAN and 3G/GPRS cloud technology has been deployed to support the field trial and enable ongoing performance data collection and system status monitoring. Users have expressed that they highly value access to system status data (battery charge state etc) which has enabled them to moderate energy usage appropriate to available resources.
• Fintech development has been accelerated during the award period. User interfaces for customer inbounding (biometrics, physical address, personal data collection) have been developed and cost estimates for next-stage development (databases and whole-system API) have been refined.
• Results from field trial tests over a 6-month period (representative typical annual seasonal variance) indicate that:
o Sizing and design of the household system are appropriate to intended use and that electricity and hot water supplies are reliable. Opportunities for value engineering to minimise capital costs have been identified.
o Sizing of the school system is appropriate to typical use, but several design improvements are required to improve electrical supply reliability.
o Electricity usage has increased steadily over time, a finding which is in keeping with work of other investigators in the field.
o Hot water usage has also increased over time, a finding which does not appear to have been reported elsewhere.
• A technoeconomic evaluation involving field trial performance data, prototype capital costs, value engineering, and market assessment, has been undertaken. This clearly defines the size of the market gap which the SolaFin2Go solution aims to fill. It also demonstrates that the system is affordable and cost effective.
The findings of the study have given the team's commercial partners confidence to pursue the concept. Measured performance data, cost analyses, and practical experience will inform the next stage of SolaFin2Go product development towards commercialisation. Field trial findings will be reported in peer reviewed journals to enable them to be used by a variety of professionals (academics, product designers, policy makers, investment analysts etc) working in the rapidly growing energy access field.
Exploitation Route The following dissemination activities will be carried out:
Project Website- A dedicated project website is set up to contain information related to project aim and objectives, to share project outcomes to general publics, stake holders and policy makers, project events
Social Media- The consortium is created and maintained project profiles in popular social media platforms including Twitter, Facebook, LinkedIn and videos on You Tube. Twitter account is used to update project activities, to showcase events and disseminate news, results etc. Videos on You Tube targeted at the consumer and the wider stakeholder group.
Non-electronic Media - Non-electronic media, such as promotional leaflet and brochures will be prepared to disseminate project outcomes at international conferences and fairs; the press releases and publications in broadcast media will be used to increase public awareness towards clean affordable energy access.
Conference attendance and publications - Project findings and results will be presented at a European International conference (such as International Conference on Solar Technologies & Hybrid Mini Grids to improve energy access conference 2020, ARE Energy Access Investment Forum) and published in scientific journals.
