ABSTRACT = {As an important new energy, solar energy has been extensively used in
the world and different types of solar energy systems have been used in different
fields. The photovoltaic power generation system has obvious advantage and high
stability compared with other energy systems. Furthermore, the small-scale photovoltaic power generation system has a wider application in the field of power generation due to the performance of high efficiency. In this paper, the optimization
research and system evaluation of small-scale photovoltaic power system have
been studied in different areas by simulation and experimental methods. Based
on the determination of photovoltaic model system, four typical geographical
locations are selected and PVsyst is applied to the simulation study. The annual
power output is 4829 kWh, 3489 kWh, 4455 kWh, 2766 kWh and the solar
energy utilization efficiency is 14.91%, 14.79%, 17.66%, 15.77% for Mexico
City, Xinyang, Changchun and London respectively from the simulation results.
The results show that the radiation conditions, the optimum tilt angle, the minimum spacing and different geographical locations are the main reasons for the difference of power generation and solar energy utilization efficiency. Subsequently,
Changchun is selected as the experimental area to carry out experimental research
and verify the conclusion of the simulation study. The volt ampere characteristic
curve and power output curve show that the photovoltaic system has no defects,
hot spots, partial shading and damage. The annual total power generation of
Changchun is 4119 kWh. Hence, the simulation results are in good agreement
with the experimental results. Consequently, the application of small photovoltaic
power generation system requires to fully consider the regional conditions and
key parameters (optimum tilt angle, minimum spacing, etc.) to obtain better
power generation efficiency.},
