The article published on May 12, 2023, explains the working principles and related aspects of solar panels. Solar cells convert sunlight into direct current through the photovoltaic effect, forming modules, panels, and arrays via series and parallel connections. Photovoltaic systems comprise multiple components, including blocking diodes and voltage regulators, and offer advantages such as renewability and environmental friendliness, with broad application prospects.

The article introduces four installation methods for solar photovoltaic modules (sloped roofs, flat roofs, sun-facing roofs, and trendy options), detailing the characteristics and advantages of each method. It also addresses FAQs such as product selection, and highlights Demuda Company's solar-related products, 18 years of industry experience, superior service, stable quality, and extensive cooperation and sales network, showcasing its professionalism.

The article introduces the MPPT controller for off grid solar energy systems. Solar energy is commonly used in remote areas to replace diesel power generation, but traditional controllers are prone to fail to start due to battery depletion. The new MPPT controller supports dual start of battery and solar energy, and can track the maximum power point of the solar panel in real time. Compared with traditional controllers, it can actually improve charging efficiency by 20% -30% and is suitable for unmanned scenarios.

The article provides a detailed explanation of the core principle of MPPT solar controller - by detecting the output voltage of the solar panel in real time, tracking the maximum power point (MPP), and charging the battery with the maximum power. Compared with traditional controllers, its theoretical efficiency has increased by 50%, and in reality, it has increased by 20% -30% due to environmental factors. It has better functions and is expected to replace traditional controllers in the future.

The article analyzes the service life and maintenance methods of photovoltaic panels. Its service life is usually 20-35 years, and the material affects its lifespan. After 25-30 years, it may need to be replaced. At this time, the power generation is about 80% of the initial amount, and proper maintenance can extend its use. Regular inspection of metal brackets, photovoltaic parameters, etc. is required for maintenance, and relevant issues should be promptly addressed to ensure normal operation.
