Mathematical modeling of photovoltaic thermal PV/T system with v-groove collector

Photovoltaic technology is one of renewable energy technology very hopeful, especially photovoltaic thermal system or PVT system. A PVT system solar air collector produces hot air and electricity simultaneously. In this study, indoor and outdoor investigation comparison of PVT system solar air collector has tested at the National University of Malaysia. The indoor and outdoor investigation conducted with variation mass flow rates from 0.01 kg/s to 0.05 kg/s at the solar intensity of 820 W/m2. Indoor and outdoor evaluation is conducted to precisely evaluate the performance improvement theorized by the researcher. The comparison between the indoor and outdoor outcome purposed to confirm each testing and attraction decision. The outdoor investigation outcomes were agreement with indoor results. Indoor investigation outcomes reliably with outdoor investigation outcomes indicated by accuracy results.

The converted Solar energy as electrical and thermal energy was named photovoltaic thermal (PVT). The aim of this study is to the analysis of different length and depth channel effect of photovoltaic thermal with ∇-groove collector by a mathematical model. The matrix inversion was used to analyze the energy balance equation. Simulation results were conducted below the solar intensity of 800 W/m2 and mass flow rate between 0.0069 kg/s and 0.0491 kg/s. Electrical and thermal efficiency was done to assess the effect of different length and channel depth of PVT system with ∇-groove collector. The effect of different length and depth of ∇-groove collector for electrical and thermal performance is caused by changed mass flow rate. The effect Increasing of the mass flow rate of collector increased the thermal and electrical performance of the ∇-groove collector.

Summary This work introduces a novel hybrid system which uses the cooling water of a concentrated PV/T as a preheated water for lithium bromide‐water‐based Kalina cycle. The PV/T is a combination between solar photovoltaic cells and solar thermal collector. The solar cells convert the sunlight into electricity, and the remaining heat gets absorbed by the collector for additional power generation. As well as, extracting the excess heat from PV cells enhances its electrical efficiency. The Kalina power cycle is mainly driven by concentrated solar parabolic collectors (CSP). The advantage of combining these 2 systems is to employ the heat rejected from the concentrated solar‐based PV cells for further electricity generation, thus increasing the system overall efficiency. The system of concentrated solar collectors is divided into 2 parts to avoid getting very high temperature for the PV cells: concentrated solar collectors with PV cells and without PV cells. Due to the high temperature of water which returns from the Kalina cycle, a cooling tower is employed to cool the water before entering the concentrated PV/T system. The mathematical model of the proposed system has been presented and simulated to investigate the effect of the main controlling variables on the proposed system performance: generator temperature, solar radiation, wind speed, and the ambient temperature. The results show that the amount of solar radiation is the primary variable for the investigated system energy productivity, while the design temperature of generator is found to be the most parameter that affects the system overall efficiency. While the overall efficiency is around 18% to 23%, combining PV/T with the proposed solar Kalina cycle increases the system overall efficiency by 22% to 27%. The electrical conversion efficiency of the proposed system is 40% to 68% much more compared to PV/T alone system.
