In order to explore the effect of waves on the power generation performance of floating photovoltaic modules at sea
photovoltaic modules with rated power of 595 W were selected as the research object. Based on theoretical analysis and physical model experimentals
the effects of maximum swing angle of 5°-30°
swing period of 5~10 s and irradiance of 200~900 W/m on the power generation performance ratio were compared and analyzed. The results show that with the maximum swing angle of the photovoltaic module increasing from 5 to 30
the ratio of the power generation of the swing photovoltaic module to that of the fixed module with a 0° tilt angle
defined as the power generation performance ratio
decreased by 5.16 percentage points. The ratio of the power generation of the swing photovoltaic module to that of the fixed module with an 18° tilt angle
referred to as the power generation performance ratio
decreased by 5.30 percentage points. Furthermore
the decline rate gradually accelerated with an increase in the maximum swing angle. Compared with the influence of the maximum swing angle on the maximum swing angle on the performance ratio
the effect of swing period variation is relatively insignificant
and the power generation performance ratio of the module increases with the extension of the swing period. The power generation performance ratio of the module decreases with increasing irradiance. When the irradiance increases from 200 W/m² to 900 W/m²
decreases by 4.61 percentage points and decreases by 5.48 percentage points.
