How to detect surface dust on solar photovoltaic panels?

At present, the main methods for detecting surface dust on solar photovoltaic panels include object detection, image segmentation and instance segmentation, super-resolution image generation, multispectral and thermal infrared imaging, and deep learning methods.

What are the components of a photovoltaic system?

The photovoltaic system consists of three main components; PV panels, charging controller, 12v 9A.h. battery, DC pump, and other electrical components (such as wires and MC4). Three panels were used to generate power to operate the pumping system. Each panel has a rated power of 100 W as shown in Fig. 1 and datasheet in Table 1. The Pv panels.

How to detect solar photovoltaic panels?

Among them, algorithms such as YOLO [11, 12], Faster R-CNN , and RetinaNet [14, 15] in object detection methods can accurately mark the position and boundary of solar photovoltaic panels in the image, but due to the need for a large amount of computing resources, they have high requirements for hardware and environment.

How to install photovoltaic panels on a rooftop?

The rooftop installation of photovoltaic panels can be accomplished using three mounting methods: independent support, enclosed attachment, and forced cooling. However, the enclosed attachment method may lead to temperature concentration and reduced photovoltaic performance.

What if the surface of solar photovoltaic panels cannot be maintained?

However, at the macroeconomic level, by 2020, the global installed capacity of solar photovoltaics has reached 707.5 gigawatts, with China accounting for 35.8 % . If the cleanliness of the surface of solar photovoltaic panels cannot be effectively maintained, it will result in huge economic losses.

Do rooftop photovoltaic panels reduce indoor heat gain?

Rooftop photovoltaic panels can serve as external shading devices on buildings, effectively reducing indoor heat gain caused by sunlight. This paper uses a numerical model to analyze rooftop photovoltaic panels' thermal conduction, convection, and radiation in hot summer areas as shading devices.
