1. What is Solar Light?
The device that converts solar energy into electrical energy and uses this electrical energy to achieve lighting is called solar light. Since the solar lamp uses solar energy as energy, it does not produce waste gas or waste. Therefore, as a new type of safe and environmentally friendly lighting fixtures, solar lamps will be more and more popular with users.
2. How Solar Light Works?
Solar cells are made using the principle of photovoltaic effect. During the day, solar panels receive solar radiation and convert it into electrical energy, which is stored in the battery through the charge and discharge controller.
When the night illumination is reduced to about 101ux (the open circuit voltage of the solar panel is about 4.5V. After the charge and discharge controller detects this voltage, the battery provides power for the LED light).
The solar panel opens circuit and the battery provides power for the LED light , So realize the lighting function. When the illuminance rises to about 110 ux in the early morning (the solar panel is short-circuited and the charge and discharge controller detects it, the battery stops powering the LED lights). The battery stops powering the LED lights.
The main function of the charge and discharge controller is to protect the battery. The above is the most basic working principle of solar lights. To achieve intelligent control of solar lights, solar lights manufacturers can install timers and motion sensors for solar lights. In this way, in the absence of solar radiation, the solar lamp is more energy-efficient and the lighting time is longer.
3. Advantages of Solar Lights
As the earth’s resources become increasingly scarce, the cost of basic energy investment is rising, and various safety hazards and pollution are everywhere. In this environment, solar lighting products have been applied subsequently. Here, we compare the advantages and disadvantages of solar lighting and mains lighting from several aspects, so as to reflect the advantages of solar lamps in the future.
3.1 Installation aspect: the installation of mains lighting fixtures is complicated: the construction of mains lighting fixtures has prescribed operation steps. First, excavate the cable trench, and then lay the concealed pipe, thread the cable through the pipe, and backfill the cable trench. Finally, install and debug. If there is a problem with any of these lines, extensive rework is required. Moreover, the terrain and lines are complicated, so the cost of labor and auxiliary materials is high. Solar lighting fixtures are easy to install: When solar lighting fixtures are installed, there is no need to lay complicated lines, just make a cement base and fix it with stainless steel screws.
3.2 Maintenance cost: In addition to the installation cost and material cost of the mains lighting. A lot of expenses will be required later. For example: electricity bills, maintenance of later lines and lamps. If the line is aging, it needs to be re-laid, which will be a lot of expense. Solar lamps only require a one-time investment, during which no electricity bills or even maintenance costs are incurred.
3.3 Safety aspects: There are hidden dangers in mains lighting fixtures: mains lighting fixtures need to lay cables, and they are high-voltage electricity. There is a possibility of electric leakage on the ground, which may cause electric shocks on rainy days. As time goes by, cables also cause safety hazards due to aging. Solar lighting lamps are safe, because it is a low-voltage product, the voltage will not cause harm to the human body, so the solar light is safe and reliable. And the solar light does not need to be wired, so there is no possibility of leakage.
In summary, solar lighting has no hidden dangers, energy saving and no consumption, green environmental protection, easy installation, automatic control and maintenance-free.
4. Structure of solar lights
Solar light fixture is composed of four parts: crystalline silicon solar panel, maintenance-free valve-controlled sealed battery, super bright LED lamp, intelligent charge and discharge controller.
4.1 Crystalline silicon solar panels
Monocrystalline silicon solar panels and polycrystalline silicon solar panels are the two most widely used crystalline silicon solar panels for solar lamps. Here are the differences between monocrystalline silicon solar panels and polycrystalline silicon solar panels, and their advantages and disadvantages.
The working principle of crystalline silicon solar panels: sunlight radiates on the semiconductor pn junction to form new hole-electron pairs. Under the action of the pn junction electric field, holes flow from the n zone to the p zone, and electrons from the p zone to the n zone , After turning on the circuit, a current is formed.
Monocrystalline Solar Panels:
4.1.1 Its efficiency is about 22%.
4.1.2 The average life span is 15 years, up to 25 years.
4.1.3 The manufacturing process is complex and consumes a lot of energy.
Polysilicon Solar Panels:
4.1.4 Its efficiency is about 18%.
4.1.5 The average life span is 10 years, up to 15 years.
4.1.6 The material is easy to manufacture and save power consumption.
In summary, the efficiency and lifetime of monocrystalline silicon solar panels are higher than that of polycrystalline silicon solar panels, but the cost is much higher. Polysilicon solar panels are accepted by the majority of solar lights manufacturers and suppliers because of their low price, high conversion rate, and long life.
4.2 Maintenance-Free Valve Controlled Sealed Battery
Solar light batteries currently used: sealed lead-acid batteries, lithium batteries. Lead-acid batteries used to be mainly used for solar street lights. Because of their large size, heavy weight, and small capacity, they were gradually eliminated by solar street lights manufacturers. Lithium batteries, small in size, light in weight, and large in capacity, are widely used by solar light manufacturers. Solar street lighting manufacturers gradually use lithium batteries replace lead-acid batteries. Here are a few points about the advantages of lithium batteries.
4.2.1 High capacity. With high storage energy density, it has reached 460-600Wh/kg, which is 6-7 times that of lead-acid batteries.
4.2.2 Long life. The service life is more than 6 years, and the battery 1C (100% DOD) with lithium iron phosphate as the positive electrode can be used for 10,000 times of charging and discharging;
4.2.3 Light weight. The weight of the same volume is about 1/5 of the lead-acid battery.
4.2.4 Wide temperature range. It can be used in the environment of -20℃–60℃.
4.2.5 Green and environmental protection. Lithium batteries do not contain toxic and harmful heavy metal elements such as lead, mercury, and cadmium.
4.3 Super Bright LED Lights
The lamps used in solar energy are mainly outdoor lamps, including street lamps, flood lamps, courtyard lamps, wall lamps, signal lamps and lawn lamps. Because the battery capacity is limited by the volume of LED lamps, the power of solar LED lamp is not very large. So solar lights manufacturers must use ultra-bright LED chips to meet the brightness requirements. At present, the brightness of solar lights exceeds 170lm/W. A few top solar street lights manufacturers have produced solar street lights exceeding 225lm/W.
4.4 Intelligent charge and discharge controller
The main function of the charge and discharge controller is to protect the lithium battery. Over-discharge and over-charge of lithium batteries will cause the decomposition and destruction of lithium-ion active materials, which cannot be reduced. Therefore, both overcharging and overdischarging lithium batteries will cause serious damage to battery performance. When the charging capacity of the lithium battery reaches 95% of the nominal value or the discharge capacity reaches 10% of the nominal value. The charge and discharge controller will open the circuit to stop the charging and discharging of the lithium battery. Together with the light sensor, the charge and discharge controller controls the solar panel to charge the lithium battery during the day and controls lithium battery to power LED lights at night.
5. Types of solar lights
With the development of solar panel technology and the decrease in cost, most outdoor lamps can now be made into solar lamps. As best solar light manufacturers and suppliers, KYDLED has sufficient technical experience. The following are the main application solar lights:
5.1 Solar street lights: Applied to village roads and country roads, it is one of the main applications of solar street lighting devices. Due to the limited power of solar street lights, there are not many cases of using solar street lights as lighting solutions on urban arterial roads. However, with the complementation of municipal lines and the technological advancement of solar street light manufacturers, the application of solar street lights on main roads will increase.
5.2 Solar garden lights: used in lighting and decoration of urban roads, commercial and residential communities, parks, tourist attractions, squares, etc. It is also possible to change the above-mentioned commercial lighting system into a solar lighting system according to user needs.
5.3 Solar flood lights: Main application scope: billboards, highways, railways, bridges and culverts, squares, buildings, courtyards, etc. The use of solar floodlights greatly facilitates installation. You can install it wherever sunlight can reach.
5.4 Solar signal lights: The role of navigation, aviation and land traffic lights is very important. In many places, the power grid cannot supply power, and solar signal lights can solve the power supply problem.
5.5 Solar lawn lights: Used in squares, parks, green spaces and other places, using various shapes of low-power LED point and line light sources to beautify the environment. Solar lawn lights can get better landscape lighting effects without destroying the green space.
5.6 Solar wall lights: Wall lights are generally installed on stairs, halls, walls and other parts of public buildings. Using solar wall lights can avoid complicated wiring procedures.
