THE THEORETICAL EVALUATION ON PHOTOVOLTAIC-THERMOELECTRIC (PV-TEG) CO-GENERATION SYSTEM PERFORMANCE
Keywords:
PV-TEG Hybrid, Thermoelectric Generator, MPPT, Incremental ConductanceAbstract
TEG is an electrical device that produces energy as a result of the difference in hot and cold
junctions. There are many studies that have been conducted on the use of TEG in solar PV
systems. PV cell depends on solar irradiation and temperature while TEG depends on the
temperature difference. TEG uses heat waste produced from solar PV systems and produces
extra energy. A simulation study was conducted using MATLAB software where the solar PV
system and TEG are connected in parallel. In this study, the maximum power point tracking
converter using the Incremental Conductance (Inc) method is used to achieve the optimal energy.
Another consideration is the solar PV system is limited to non-shading conditions. The obtained
results show that the PV-TEG co-generation system produced 17% more energy when compared
to a standalone PV system. By modifying the temperature and irradiance, the efficiency of PV-
TEG co-generation is also compared to PV standalone.
