Optoelectronics Technology Co., Ltd. Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. LED lamp power supply efficiency input power minus the output power value of this parameter is particularly important lights solar system, the greater the efficiency, the lower the value, it means that a large part of the input power is converted to heat that comes out; if it is installed in the lamp will produce a very high temperature, combined with our LED light efficiency than the one distributed by the heat, it will produce a higher temperature superposition. Our power all internal electronic parts life will be shortened with increasing temperature. Efficiency is decided so that the life of the most fundamental of the power factor, efficiency can not be too low, otherwise the power consumed in the heat too. More efficient than non-isolated isolated, usually more than 80% can, however, about the efficiency and light board matching connection. Optoelectronics Technology Co., Ltd.

The solar modules used solar panels facing the square is usually placed equator, there is a certain inclination relative to the ground plane. 2. Fixed-area panels, and solar irradiance is proportional to the current and almost independent of temperature 60w solar lights, and the voltage (power) decreases with increasing temperature; general crystalline silicon plate voltage drop 0.5 / ℃, so the battery board to be installed in a ventilated place to keep cool, and a location not too many components to install. 3. Any part of an array of photovoltaic panels can not be shaded solar lights, solar panels if there is shade lights solar panels much money, they will not produce and will form a reverse bias current, which means that the cover assembly fever will consume power, over time, the formation of the fault. (This is called the heat island effect. Prevent heat island effect, generally inclined to put the solar panels, the solar cell surface can not be attached to the obstruction.) 4. accidentally blocked inevitable, it required a bypass diode protection. If all the components in parallel, you do not need a bypass diode; if required output voltage 24V (or higher), you must have two (or more) components in series, then you need to add a bypass diode to control the photovoltaic system current. Either blocking diode in each parallel branch, but also between the array and controller dry road, but a number of branches and connected into a large system, it should be in every branch on the way with a blocking diode to prevent slip fault or current shadowing caused by a strong current branch weak current flowing tributary of the phenomenon (controller without this feature). Small systems in the dry road with a blocking diode enough, both of which are not available because each diode will be down 0.4 ~ 0.7V is 6 percent a 12V system. 10w solar lights, solar street Ou Park, Xinjian County, solar street lighting is provided by the EU can Optoelectronics Technology Co., Ltd. Nanchang. Nanchang Ou Optoelectronics Technology Co. (www.okled.cn) Jiangxi Nanchang, solar and renewable energy leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Europe may photoelectric leadership with the staff warmly welcome all inquiries negotiations to create Europe can photoelectric a better future.
