How to judge the degree of dust accumulation on photovoltaic panels
In this work, we propose a methodology that uses a machine learning approach to estimate different levels of dust accumulation in photovoltaic panels. . The dust deposition on the surfaces is a complex phenomenon which depends on a large number of different environmental and technical factors, such as location, weather parameters, pollution, tilt angle and surface roughness. Hence, it becomes crucial to investigate the key parameters which. . Thus, it is necessary to develop techniques that allow us to assess the level of dust accumulation in the panel surface in order to schedule a proper maintenance and avoid losses associated with the reduction of the delivered power and unexpected faults. Solar panels generate electricity when sunlight reaches their photovoltaic (PV) cells. This study presents a comprehensive review and analysis of the influence of dust deposition. . [PDF Version]
How many wind levels are needed for household wind power generation
To operate practically and efficiently, domestic wind turbines generally require steady wind speeds of at least 10 to 15 mph. Sites with average wind speeds below this range may not be suitable for wind power generation unless equipped with auxiliary systems (such as batteries or. .

Microgrid levels are divided into
The Microgrid Exchange Group defines a microgrid as "a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode." [PDF Version]
