Four sets of photovoltaic power generation systems were built: monocrystalline V-trough concentration, polycrystalline V-trough concentration, monocrystalline flat-panel, and polycrystalline flat-panel photovoltaic power generation systems, and experimental tests were carried out. The results show that under the same meteorological conditions, whether using monocrystalline silicon solar cells or polycrystalline silicon solar cells, the maximum and average electrical power of the V-trough concentrated photovoltaic power generation systems are greater than those of the flat-panel photovoltaic power generation systems. Among them, the maximum and average electrical powers of the monocrystalline V-trough concentrated photovoltaic power generation system are greater than those of the polycrystalline V-trough concentrated photovoltaic power generation system. The maximum and average electrical efficiencies of the monocrystalline V-trough concentrated photovoltaic power generation system are 3.70% and 1.48% higher than those of the monocrystalline flat-panel photovoltaic power generation system, respectively. The maximum and average electrical efficiencies of the polycrystalline V-trough concentrated photovoltaic power generation system are 3.13% and 1.99% higher than those of the polycrystalline flat-panel photovoltaic power generation system, respectively. The maximum and average surface temperatures of the solar cell in the monocrystalline V-trough concentrated photovoltaic power generation system are 1.13°C and 3.27°C lower than those in the monocrystalline flat-panel photovoltaic power generation system, respectively. The maximum and average surface temperatures of the solar cell in the polycrystalline V-trough concentrated photovoltaic power generation system are 0.95°C and 3.61°C lower than those in the polycrystalline flat-panel photovoltaic power generation, respectively.
