Problems solved by technology

For this reason, some solar simulator manufacturers adopt the method of changing the input power of the simulator to adjust the radiation intensity of the output light source. Although this method can realize the change of the radiation intensity, it also makes the distribution of the output spectrum more or less occur. has changed, the accuracy of the test method is not high

Abstract

The invention discloses an indoor testing system for a low-power condensing assembly. The indoor testing system comprises a transient I-V characteristic tester and an adjustable condenser, wherein the transient I-V characteristic tester and the adjustable condenser are opposite in position; the adjustable condenser comprises a reflecting material, a fixed bracket, an adjusting slide bar and a rotatable reflecting plate; one end of the adjusting slide bar is movably connected with the fixed bracket; the other end of the adjusting slide bar is movably connected with the back surface of the rotatable reflecting plate; and the reflecting material is arranged on the front side of the rotatable reflecting plate. According to the indoor testing system for the low-power condensing assembly disclosed by the invention, by virtue of the adjustable condenser which can be flexibly adjusted, the low-power condensing conditions of 1 to n times can be simulated; and by virtue of a novel indoor testing method, I-V characteristics of the assembly in the condensing condition can be tested in the standard test condition of a photovoltaic assembly; and the adjustable condenser can be used by matching with a conventional I-V characteristic tester, so that the applicability is high.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic component testing equipment, and in particular relates to an indoor testing system for low power concentrating components. Background technique [0002] Concentrating photovoltaic systems have always been concerned by researchers because of their potential to reduce the cost of solar power generation. For high-power concentrating systems of tens to hundreds of times, multi-junction high-efficiency cells are the mainstay. In actual use, the 2-10 times low-power concentrating system has the advantages of relatively low requirements for sun tracking accuracy, battery cooling effect, etc., and high system reliability, so it has certain market prospects. At present, there are few domestic and foreign researches on this aspect of testing. For example, IEC has only one standard on concentrating photovoltaic testing: IEC62108:2007, which has relatively general requirements for electrical performance...
