ABSTRACT
Renewable energy plays an important role in achieving the ultimate objective of replacing fossil fuels. Solar energy is considered one of the cleanest, most sustainable, and abundant sources of renewable energy, among other renewable energy sources. Hybrid PV/T (PVT) is known as solar energy harnessed by solar thermal collectors and solar photovoltaic (PV) collectors to simultaneously produce heat and electrical power.
This thesis study introduces a PVT-ORC system, which is an organic Rankine cycle (orc) integrated with a hybrid photovoltaic thermal system (PVT), PVT collectors transform solar radiation into useful electrical and thermal energy, and the ORC utilizes the thermal energy from the PVT collector to generate additional electrical power. Thermal energy from the PVT system is also utilized in producing hot water for domestic purposes.
Analysis in this study is done by comparing energy production of a PVT-ORC system with a higher fluid outlet temperature (80℃) to a PVT system with a lower fluid outlet temperature (60℃), the overall performance, efficiency, economic parameters, electrical and thermal outputs are evaluated for an annual simulation cycle.
This system analysis was conducted by solving energy mathematical equations; modelling and simulating of the overall system were done by using engineering equation solver (ees) and system advisor model (sam) software.
The PVT system with Tout at (80℃) produces 1,055,603.7kWh/yr electrical energy and 3,589,828.8kWh/yr thermal energy. The PVT system with Tout at (60℃) produces 1,272,815kWh/yr electrical energy (20.58% more than PVT system with 80℃) and 1,018,612.6kWh/yr thermal energy (71.63% less than PVT system with 80℃) per annum.
The ORC system’s electrical energy output was estimated at 362,780 kWh/yr with R134a as the selected organic fluid. The PVT-ORC system total annual electrical energy output was approximately 1,418,383.7kWh/yr.
The payback period (SPP) was projected at 13.5years and 15.8 years for PVT system and PVT-ORC system respectively.
