Abstract

A solar photovoltaic panel test platform includes a test section and a signal processing section. The test section has a frame, a light-emitting unit disposed on the frame, a first angle adjustment unit and a second angle adjustment unit arranged on the frame, an air-cooling unit mounted on the first angle adjustment unit for connecting with a first solar photovoltaic panel, and a water-cooling unit mounted on the second angle adjustment unit for connecting with a second solar photovoltaic panel. The signal processing section is connected to the first and second angle adjustment units, the light-emitting unit, the air-cooling unit, the water-cooling unit, and the first and second solar photovoltaic panels. The signal processing section serves to receive sensing signals and transmit control signals. The solar photovoltaic panel test platform can provide different illuminations, angles of incidence and heat dissipation modes to test the efficiency of the solar photovoltaic panels.
