Applications
In order to improve the conversion efficiency of solar cells, the
method of automatically tracking the sun is usually adopted, so
that the solar panels are facing the sun. According to the
determination, under the same environmental conditions, the power
generation of an all-round automatic tracking solar photovoltaic
power generation system is about 35% higher than that of a fixed
solar photovoltaic power generation system. Especially for systems
using monocrystalline silicon solar cell modules, due to the high
price, it is hoped to obtain as much solar radiation as possible,
and sun tracking can be considered.
There are three types of solar cell array tracking methods: flat
single-axis tracking, inclined single-axis tracking, and dual-axis
tracking. This courseware introduces single-axis tracking.
