Portable photovoltaic assembly power simulation device

Abstract

The invention discloses a portable photovoltaic assembly power simulation device. The portable photovoltaic assembly power simulation device comprises a device main body; an irradiance sensor, an LCD,a numeric keypad, a temperature sensor, a control module and a power source module are arranged in the device main body; the irradiance sensor is disposed on the front surface of the main body; the temperature sensor is connected with the back surface of the main body through a wire; the LCD is disposed at the middle portion of the main body; the numeric keypad is disposed at the lower portion ofthe front surface of the main body; the control module is disposed at the upper portion of the interior of the main body; and the power source module is disposed at the lower portion of the interiorof the main body. According to the portable photovoltaic assembly power simulation device of the invention, the initial characteristic parameters of a photovoltaic assembly are entered, the quantity of irradiation received by the photovoltaic assembly and the temperature of the backboard of the photovoltaic assembly are acquired in real time, and therefore, the real-time power of the assembly under a theoretical condition can be theoretically calculated; and since the actual power of the assembly can be measured, the working state of the photovoltaic assembly can be easily analyzed, and corresponding maintenance measures can be adopted.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module power testing, and more specifically refers to a portable photovoltaic module power simulation device. Background technique [0002] With the development of modern industry, the global energy crisis and air pollution problems are becoming more and more serious. The traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more serious. At the same time, about 2 billion people in the world do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human...
