Solar power of the common technique is to ask the rural solar street light

Many solar power has a lot of questions, so what are the common technical problems? Let the price of solar street lamps manufacturer to introduce to us. As a kind of both environmental protection and energy saving treatment plan, LED lighting in their car, family, office building,

many people have many questions about solar power. The main common technical problems? Then make a reasonable price to introduce our solar street lamp manufacturers. As a kind of environmental protection and energy saving treatment scheme, led lighting has been in the car, home, office buildings, hotels, airports, and street lamp and so on a wide range of applications to find his own position. However, in addition to the cost barrier, also need to deal with the large-scale commercial application, such as color and flash of light, heat, uniformity and other technical problems. In addition, the emphasis on clean energy and reduce the cost of solar panels also caused the boom of the solar industry at that time. Q: electricity is collected by solar panels to recharge the battery what is the main plan? The answer: solar panels as a practical way of commercial and residential electricity generation, now has been widely accepted by people. However, despite the technological progress, the cost of solar panels is still very expensive. The most costly from panel itself. Here, the size of the panels ( And its cost) Will increase with the increase of the required power output. Therefore, in order to create a more small size and better cost-effective processing plan, in a larger extent, it is very important to improve the function of the panels. In general, solar panels have energy to recharge the battery, which in turn will provide terminal application circuit used to support the operation in the absence of sun. Planning in order to better complete the solar battery charger, it is necessary to understand the characteristics of the solar panels. First of all, the solar panels will leak, because of its large glue battery will discharge through the panels in dark conditions. In addition, every four solar panels has the characteristics of large power point curve, so when the load characteristics and panels do not match, energy extraction will be reduced. Our goal is to continue at a higher power point loading of solar panels, to make full use of existing solar energy, which in a larger extent, reduce the cost of panels. Usually, can choose the panels in series schottky diode leakage problems to solve the panels. Reverse leakage reduced to very low values; However, the schottky diode (dc voltage drop Under the condition of high current consume a large amount of power) Will still constitute the energy loss. Therefore, require expensive radiator and elaborate layout to keep schottky diode at low temperature. Dealing with this kind of power consumption of a more useful method is to use based on the ambitions of the metal oxide semiconductor field effect transistor diode instead of schottky diode. This will reduce the dc voltage to 20 millivolts, and significantly reduce power consumption, at the same time reduce the complexity of the cooling layout, shape size and cost. Fortunately, due to some supplier of integrated circuits is now producing ambition diode (of this specification For example, the LTC4412 LingLiTe) , the policy can be easily completed. However, there are still two questions, namely: float charging pressure control battery charge; And the better power points loading panels; 。 These problems can usually be by selecting the switching mode charger and efficient step-down regulator to solve.
