Solar photovoltaic panels, the common types of solar panels are monocrystalline and polycrystalline. If the customer does not have a dedicated measuring instrument when purchasing, they can choose the simple method to measure the area. The larger the area, the greater the panel power.
The selection of light sources is an important step for solar street lamps. Nowadays, there are very few dedicated light sources for solar street lamps. To minimize the loss of limited energy, direct current light sources should be selected as much as possible. The common light sources nowadays include DC energy-saving lamps, high-frequency electrodeless lamps, low-pressure sodium lamps and LED light sources.
Solar street lamp drivers are products specially developed for LED street lamp systems, used to provide stable power supply for LED lamps. By adopting advanced electronic power supply technology, two output modes, namely high-efficiency enhancement and ultra-energy-saving pulse width modulation (PWM), have been designed. LED lights can be turned on in high-efficiency and enhanced mode when needed (during the first half of the night when there are many people and vehicles) to provide good lighting, while at other times (during the second half of the night when there are fewer people and vehicles), they can be output in ultra-energy-saving mode to save battery power.
Solar panels can be classified into monocrystalline and polycrystalline. The price of monocrystalline is higher than that of polycrystalline. Since the customer did not have professional measuring instruments when purchasing, it is advocated to use the scale area for measurement. The larger the scale area, the larger the scale of the solar panel, which is directly proportional to the power of the solar panel. To select the appropriate solar panels and batteries based on the power of the lamp and the duration of sunlight, parameters need to be obtained through scientific calculation.
The commonly used types of light sources include: trichromatic energy-saving lamps, high-pressure sodium lamps, low-pressure sodium lamps, leds, and ceramics, which store electrical energy. It adopts ultra-bright LED lights as the light source and is controlled by an intelligent charge and discharge controller. Ordinary electric lighting is used instead of traditional street lamps, which can ensure normal operation for more than 15 days in rainy and cloudy weather.
Its system consists of LED light sources (including drivers), solar panels, batteries (including battery insulation boxes), solar street lamp controllers, street lamp poles (including foundations) and auxiliary material lines. This article analyzes and compares the light sources of solar street lamps. The specific selection should refer to the road conditions and customer requirements. It should be noted that all kinds of light sources have certain power, limitations and general standards. When choosing power, try to select the power of a common light source.
