How solar panels work

The core principle of solar panels is the "photovoltaic effect". When sunlight radiates to the surface of the solar panel, the semiconductor material (usually single crystal silicon) in the cell absorbs photon energy, causing the electrons therein to transition and form a potential difference, thus generating a DC current. This process does not require any mechanical movement and relies entirely on the conversion of light energy into electrical energy. Multiple cell cells are formed into solar panels in series and parallel, and the output voltage and current can be flexibly configured according to application requirements. The generated electrical energy can be directly powered, stored in a battery, or converted into alternating current through an inverter, and is widely used in off-grid systems, home photovoltaics, transportation lighting, agricultural power and other fields.

This not only means that the power generation capacity per unit wattage is stronger, but also improves the overall system efficiency in actual applications.
Monocrystalline silicon has better low-light response capabilities, and can continue to produce electricity even in cloudy days, early morning or evening environments with poor lighting conditions to ensure the stable operation of the system. This reliability is of great value for users in remote, off-grid, or in unstable areas.
Strong weather-resistant structural design, adapted to various complex environments:
In terms of materials and process, this series of solar panels also demonstrates outstanding professionalism. Each panel uses anodized aluminum alloy frame, which has good corrosion resistance and structural strength, and can withstand extreme climate influences such as long-term outdoor wind and sun, salt spray corrosion, and is widely used in harsh environments such as seaside, desert, and plateau.
The panel surface is covered with high light transmittance tempered glass, which not only improves the transmission efficiency of sunlight, but also effectively protects the battery cells from external shocks, dust or water vapor. The glass surface has anti-reflection and self-cleaning characteristics, which can reduce the power generation loss caused by dust coverage to a certain extent and reduce the frequency of manual cleaning.
The overall structure design is waterproof and sealed and has excellent waterproof and dustproof grades (usually IP65 and above). Even in complex environments such as rainy season, windy and snowy weather, it can operate stably for a long time and extend its service life.

Its metal structure is dense and a uniform oxidative protective layer can be formed on the surface to prevent rust. Even if exposed to humid and salty air, corrosion problems are not prone to occur. While maintaining high strength, it has a low density, so that the entire lamp body remains lightweight on a solid foundation, which is easy to install and maintain. It is especially suitable for improving construction efficiency in large-scale lamp projects.
Based on the raw materials, DDK also carried out two fine processes: high-temperature spraying and anti-corrosion treatment on the surface of the lamp body. The powder coating is evenly adhered to the surface of the lamp body through electrostatic spraying technology, and then cured at high temperature, so that the coating has strong adhesion and is not easy to fall off. It not only increases the aesthetic texture, but also effectively blocks the direct corrosion of the metal by air and water vapor. The surface coating has added UV-resistant and salt spray components to improve the stability of use in natural environments such as acid rain, high salt spray, frost, and greatly extend the outdoor service life. It is especially suitable for high-humidity areas such as coastal ports, mountain parks, and Jiangnan wetlands.
