Techno-economic analysis, also known as techno-economic assessment (TEA), evaluates a product, process, or service with a focus on economic aspects. It weighs the technological advancement against the financial costs. A mathematical model is developed first based on which parameters such as initial investment, running cost, and business model are analyzed. A TEA is typically used in the following examples: Evaluating the economic feasibility of a technology: With a TEA, the developed technology can be analyzed and evaluated to determine whether it can affect economic gains for the given set of conditions.Guiding research and development: Sensitivity analysis can help determine the impact of a variation in output variables with the change input variables. This analysis, when carried out with a TEA, can help in segregating the targeted research outcomes with the highest chances of yielding financial gains.Quantifying uncertainty and risk: When dealing with financial aspects related to business, uncertainty in the model needs to be taken into account. Sensitivity analysis can be employed for determining economic uncertainty. The parameters that impact the model uncertainty the most can also be detected.

Wood is a valuable component of C&D waste. It is reported that one-fourth of the world’s virgin wood is used in construction (Yeheyis et al. 2013). In some countries such as Canada, Sweden and Denmark wood constitutes a significant proportion of the C&D waste (Trochu, Chaabane, and Ouhimmou 2018). Recycling of wood waste to produce wood composites, particleboard, and biofuel are among the most efficient wood waste management practices that can potentially alleviate the environmental burdens of C&D wood waste (Akhtari et al. 2021; Hossain and Poon 2018). However, there is a need to ensure the feasibility of converting C&D wood waste to biofuel and other products, because lack of economic incentives impedes any effective management plans for C&D waste (Yuan et al. 2011). Therefore, techno-economic analysis should be performed for evaluating new technologies and different waste diversion scenarios (Lan et al. 2021). Techno-economic assessment helps decision-makers investigate the economic feasibility of projects using the net present value (NPV), internal rate of return (IRR), payback period, and cost-benefit ratio of projects as the primarily indicators (Kaoma and Gheewala 2021; Zhao, Leeftink, and Rotter 2010).

Based on the conclusions drawn from this study, some suggestions for future work include (i) investigating the interaction between several passive and active cooling to improve the PV-T performance, (ii) experimental testing of the proposed configuration, (iii) optimising the design parameters to further increase energy and exergy efficiencies, (iv) techno-economic assessment of the proposed technology, (v) examining the lifetime and stability of the PV-T system under harsh environment, and (vi) investigating the scalability of the proposed cooling system for large-scale PV-T systems.
