With the aim of diversifying different energy sources and achieving net zero emissions, hybrid renewable energy sources (HRES) represent the future of the world. However, several HRES simulation software do not integrate the Photovoltaic/thermal (PV/T) system. This article designs an optimal design model for a tri-hybrid Photovoltaic/thermal/hydroelectric (PV/T/H) system for a rural locality in the North Cameroon region.

Article Synopsis
  • - This paper investigates the use of vegetable oils (rapeseed and jatropha) as heat transfer fluids in Parabolic Trough Solar Concentrators, exploring six different configurations by combining these oils with SiO and AlO nanoparticles.
  • - Using a 1-dimensional PTSC model and validated through numerical methods in Matlab, the research shows that rapeseed oil improves thermal efficiency by about 4.21% over jatropha.
  • - The study finds that increasing the volume fraction of nanoparticles enhances thermal efficiency, with specific combinations like AlO/rapeseed leading to significant improvements, but highlights that nanoparticle effects on heat capacity must also be considered for optimal performance.

To assess the production potential, economic profitability and ecobalance of the photovoltaic/thermal (PV/T) system in Cameroon, different configurations of HTF based on water, vegetable and synthetic oils, coupled with different forms of titanium dioxide () are used. A numerical code is written in Matlab. The PV/T model connected in direct contact PV-absorber is validated and a multi-objective optimization of the system is performed.
