Aims and objectives
This task aims to identify opportunities to increase large-scale deployment of solar energy by addressing the challenges of system design for photovoltaics in agriculture. It will do so by undertaking detailed modelling and design to achieve an understanding of the role of mono, bifacial photovoltaic and flexible technologies in the context of complex environmental factors and the impact on agricultural activities.
• Develop improved yield modelling for AgriPV systems: considering spectral albedo impact on bifacial systems, and with validation using data from a proposed experimental AgriPV system (~50 kW)
• Design and optimization of PV systems considering agricultural land-use: access requirements, ground conditions with varying spectral albedo, impact of soiling, monitoring requirements.
• Reciprocal impact of photovoltaic system and agricultural land use: impact on photosynthetically active radiation, impact on microclimate, potential shading by crops, Soiling impact study with experimental data.
6.2.4 Emerging Applications
Photovoltaic deployment at TW scales will require ultra-low-cost photovoltaics that operates at high efficiency for decades. Complementing the TW scale deployment, there are emerging sectors where photovoltaics may not have the same potential for scale of deployment but will have an increasing and important role and at a higher value point. These areas include the transport, agriculture, space and building sectors. Each of these sectors presents distinct photovoltaic requirements, considered in Table 1. The development of photovoltaics built-for purpose across these sectors presents a growing opportunity for Australia to continue to increase the uptake of renewables, drive reductions in carbon emissions across diverse sectors, increase energy resilience, develop new photovoltaic technologies, capture valuable IP, and diversify the photovoltaic industry in terms of technologies, skills, and supply chains.

CSR Viridian, Lendlease, will need to explore more options in due course.
Research Activities and Plans
• Report on market and techno-economic analysis
• Review and develop digital tools to predict building to city scale opportunities.
• Assess the operation, performance and stabilities of existing and emerging BIPV (in field)
• Target lab scale demonstration of BIPV windows with >40% average visible transmittance, active area efficiencies of >15% and lifetimes of >10,000 hours (Years 2- 4)
• Development of module architectures to support scaling BIPV windows to achieve highefficiency and fulfill design aesthetics criteria (Years 3-8)
