Solar assembly test method and device thereof

Abstract

The invention discloses a method for testing a solar energy component and a device thereof. The invention is characterized in that: a, performance parameters of the solar energy component are measured; b, longitude and latitude of the measured place are obtained by a GPS positioning system; c, meteorological data in the NASA database is transferred according to the longitude and the latitude, so as to obtain the data of annual illumination and temperature; d, annual generated energy of the component at the measured place is calculated according to the step a and the step c; the device comprises a processor, an A/D convertor, an electronic load and a sensor group, wherein, the processor receives the signals measured by the sensor group by the A/D convertor, the electric load which is connected on the sensor is taken as an artificial load of the measured component; the device is characterized in that the device also comprises a GPS positioning module which is connected with the processor by the data interface on the processor. The invention utilities the detection data of the GPS positioning system to transfer the NASA meteorological data and realizes the prediction of annual generated energy of the measured component, thus being beneficial to the construction and maintenance detection of the power station.

Description

technical field [0001] The invention relates to an electrical testing method and a device thereof, in particular to a testing method for testing the performance of a solar module and a testing device for realizing the testing method. Background technique [0002] At present, fossil energy is gradually exhausted. Due to the universality, longevity and cleanness of sunlight, solar power generation will be an important source of future energy composition. Photovoltaic power station is a kind of energy production device that utilizes the photovoltaic characteristics of solar cells, receives radiated sunlight, generates photogenerated current, and supplies various loads through adjustment, transformation, storage, and distribution. Its basic components are: ① solar cell array ; ② storage equipment; ③ charge and discharge, inverter control mediator; ④ transmission, transmission, distribution equipment. Among them, the solar battery array (also known as solar modules), composed of...

Problems solved by technology

[0004] However, the above tests on components are applicable to the daily maintenance of components after the power station is established. In the feasibility demonstration stage before the construction of the power station, the first consideration is the selection of the location of the power station and the number of components required to form the power station. Among them, the location of the power station Natural and geographical conditions need to be considered: meteorological data (solar radiation energy resources, etc.), longitude, latitude, altitude, geology, earthquake, flood, temperature, wind speed, longest rainy days in a year, thunderstorms, sandstorms, hail, air cleanliness (acid rain ), environmental impact, etc., according to the local solar irradiance (as far as the surface of our e
