A detection system and method for a household rooftop photovoltaic power station

Abstract

The invention discloses a residential house roof photovoltaic power station detecting system and a method thereof. The system includes a pressure water module, a photovoltaic panel detecting module, a grid-connected inverter detecting module, a charging watt hour meter detecting module and a control main module. Voltage and current on different sides of a photovoltaic panel and a grid-connected inverter and pulses of a charging watt hour meter are collected. The states of electric devices are judged and pressure water is let in for cleaning the photovoltaic panel, and data is uploaded. According to the invention, all the electric devices of a residential house 5kwp roof photovoltaic power station are detected. Therefore, power generation capacity and gain of the system are improved. Practical values in aspects of accurate positioning and timely dispatching of professional maintenance workers are achieved.

Description

technical field [0001] The invention relates to the application of operation and maintenance of new energy electrical equipment by using the sensor detection technology of the Internet of Things, and in particular to a detection system and method for a household rooftop photovoltaic power station. Background technique [0002] Most areas on the earth can receive sunlight all year round. Compared with nuclear power and thermal power, solar energy is inexhaustible. In the past ten years, the rapid development of photovoltaic power generation technology has provided a broad stage for people to use solar power to generate electricity. The photovoltaic power stations built earlier are basically large and medium-sized centralized photovoltaic power stations, covering an area of ​​more than 1,000 mu with an installed capacity of more than MW; these large and medium-sized centralized photovoltaic power stations are manned for inspection and have a complete set of operation and maint...

Problems solved by technology

However, this type of system or cleaning equipment is very powerful, but the cost of the equipment is also very expensive, such as the photovoltaic dust automatic cleaning machine is as high as 10,000 yuan

For households who expect to receive 400 to 500 yuan of income per month, especially those in need, these large and medium-sized photovoltaic power station technologies cannot be directly copied and used

The photovoltaic panels and grid-connected inverters of residential rooftop photovoltaic power plants are typical high-tech equipment. It is impractical to rely on household inspection and judgment by households. It is impractical for households to climb directly on the roof or stand on ladders Cleaning by hand is extremely unsafe.

[0006] At present, grid-connected inverters and billing watt-hour meters with advanced functions have remote data interfaces, which can upload the inspection results of corresponding links to remote places to achieve partial inspection results, but grid-connected inverters and billing watt-hour meters themselves also need The object to be inspected, and the photovoltaic panel is the original equipment for power generation, which needs inspection and maintenance
