Crowdfunding in energy begins as a response to reduced investments (both governmental and private) into the transition to decarbonized energy systems and to the spread of innovative business models and approaches conductive of greater participation of citizens and communities in distributed renewable energy projects. This chapter presents results of a worldwide overview of the use of crowdfunding in the energy industry. Evidence gathered from available energy crowdfunding platforms highlight a very new, but quite dynamic sector. The crowdfunding tool has been applied in most of its forms, ranging from peer-to-business lending to pure donation, with strong environmental and social mission and the explicit aim of increasing participation of citizens in sustainable energy investment. Evidence also shows that, despite maintaining their environmental and clean energy focus, some energy platforms have begun to move from niche, grass root initiatives into larger projects and collaboration with energy private sector and institutional finance.
Westacott P, Candelise C, 2016, Assessing the impacts of photovoltaic penetration across an entire low-voltage distribution network containing 1.5 million customers, IET Renewable Power Generation, Vol: 10, Pages: 460-466, ISSN: 1752-1416
Deployment of grid-connected photovoltaics (PV) in the UK has increased rapidly. By 2014 there were over 650,000 installations (over 5 GWp), spread over different market segments (on site of existing domestic and non-domestic electricity demand customers, or connected directly to the network, e.g. solar farms). This rapid deployment and diverse market segmentation raises questions about impacts upon the electricity network. Here the authors present a novel geographical information system framework which maps current PV deployment and electricity demand to sensitive spatial resolution and by market segment. This is used to understand how current PV deployment affects power flows between the high-voltage (HV) and low-voltage (LV) network. The analysis reveals that overall, current LV PV generation is significantly below summer daytime LV demand – with over half of the areas investigated showing electricity demand five times greater than peak PV generation. Interestingly a small number of areas exhibit peak PV generation greater than demand, where reverse power flow from LV to HV may occur. The framework is hence capable of identifying the areas where network impacts are likely to occur and will also be useful to consider how integration strategies, such as energy storage and demand response could facilitate further PV deployment.

Westacott P, Candelise C, 2016, A Novel Geographical Information Systems Framework to Characterize Photovoltaic Deployment in the UK: Initial Evidence, Energies, Vol: 9, ISSN: 1996-1073
Globally, deployment of grid-connected photovoltaics (PV) has increased dramatically inrecent years. The UK has seen rapid uptake reaching over 500,000 installations totalling 2.8 GWpby 2013. PV can be installed in different market segments (domestic rooftop, non-domestic rooftopand ground-mounted “solar-farms”) covering a broad range of system sizes in a high number oflocations. It is important to gain detailed understanding of what grid-connected PV deploymentlooks like (e.g., how it deployed across different geographic areas and market segments), and identifythe major drivers behind it. This paper answers these questions by developing a novel geographicalinformation systems (GIS)-framework—the United Kingdom Photovoltaics Database (UKPVD)—toanalyze temporal and spatial PV deployment trends at high resolution across all market segments.Results show how PV deployment changed over time with the evolution of governmental PVpolicy support. Then spatial trends as function of local irradiation, rurality (as a proxy of buildingand population density) and building footprint (as a proxy for roof-area) are analyzed. We findin all market segments, PV deployment is strongly correlated with the level of policy support.Furthermore, all markets show a preference to deploy in rural areas and those with higher irradiation.Finally, local clustering of PV in all market segments was observed, revealing that PV is not spreadevenly across areas. This work reveals the complex nature of PV deployment, both spatially and bymarket segment, reinforcing the need capture this through mapping.

Houari Y, Speirs J, Candelise C, et al., 2013, A system dynamics model of tellurium availability for CdTe PV, Progress in Photovoltaics: Research and Applications, Pages: n/a-n/a, ISSN: 1099-159X
The routine availability of key component materials has been highlighted as a potential constraint to both extensive deployment and reduction in production costs of thin-film photovoltaic (PV) technologies. This paper examines the effect of material availability on the maximum potential growth of thin-film PV by 2050 using the case of tellurium (Te) in cadmium telluride (CdTe) PV, currently the dominating thin-film technology with the lowest manufacturing cost. The use of system dynamics (SD) modelling allows for a dynamic treatment of key Te supply features and prospects for reductions in PV demand via material efficiency improvements, as well as greater transparency and a better understanding of future recycling potential. The model's projections for maximum Te-constrained CdTe PV growth by 2050 are shown to be higher than a number of previous studies using static assumptions—suggesting that a dynamic treatment of the resource constraints for CdTe inherently improves the outlook for future deployment of this technology. In addition, the sensitivity analysis highlights certain complex correlations between the maximum potential CdTe growth by 2050 and the rated lifetime of PV modules as well as the reported size of global Te resources. The highest observed sensitivities are to the recovery rate of Te from copper anode slimes, the active layer thickness, the module efficiency and the utilisation rate of Te during manufacturing, all of which are highlighted as topics for further research.

Gazis E, Candelise C, Winskel M, 2013, Cost Leadership or Diversification? Assessing the Business Strategies of PV Manufacturers Using Case Studies from the USA and the UK, 28th European Photovoltaic Solar Energy Conference and Exhibition
The recent explosive growth of the PV sector combined with the multiple technological advancements have allowed for extensive experimentation in terms of applications and business models. This paper follows on a previous market assessment and offers a mapping of the various business strategies adopted by PV firms. It investigates real case-studies to analyse the benefits and dangers related to diversification through product and market differentiation. Finally it provides insights for the growth potential of such firms taking into consideration not only the techno-economic characteristics that are intrinsic to each one, but also the wider socioeconomic environment. The analysis combines literature research with original empirical evidence gathered using interviews with PV experts and comparative firm-level case studies. It then draws upon innovation studies, technological transitions and business literature to provide a novel analytical framework for the understanding of the factors facilitating or hindering the successful commercialisation of innovative PV applications. This work is part of the EPSRC’s Supergen PV21 Consortium (PV Materials for the 21st Century) and as such it draws upon leading expertise in TF PV technologies.

Photovoltaics (PV) are currently the prevailing solar energy harvesting technology, and integration of such systems in the power generation mix has been promoted by several governments through policy intervention. Thin film (TF) technologies in particular are considered to have the potential for low cost manufacturing and diverse applications beyond the conventional flat-plate modules. However, future development of the TF PV sector will depend not only on intrinsic factors including technological advances and market characteristics, but also on the interaction of the sector with the incumbent power regimes and the pressures from the energy landscape. This paper provides a summary of the ongoing work on a market assessment and an innovation systems-based analysis of TF PV technologies, with particular focus on product differentiation for innovative applications. It also offers a novel framework for the analysis and the understanding of the potential and the barriers for TF innovation within current and evolving PV and energy markets, so helping to inform policy decisions on TF innovation and niche market management. This work is part of the EPSRC’s Supergen PV21 Consortium (PV Materials for the 21st Century) and as such it draws upon leading expertise in TF PV technologies
