The Core Advantages of Solar Street Light Solar street lights are getting more popular these years. It is a dependable source of lighting the streets all over the world. Solar street lights work by using solar power, storage battery and the solar charge controller. It controls the charging and discharging of the battery. The control methods are divided into two types: light control and time control. When the sun shines on the surface of the solar cell, the electric energy generated by the solar cell charges the battery through the controller; at night, the ray of light gradually weakens, and the working voltage and working current of the solar cell continue to decrease. When the working voltage is lower than the set voltage of the controller, the controller will start the load. Then the solar street light will turn on. When it reaches the setting time or the ray of light is too strong, the controller will automatically turn off the load and the solar battery starts to charge. This process will circulate constantly. Today's solar street lights are high-tech. Solar street lights are controlled by intelligent solar charge controllers, which can automatically adjust the brightness of the lights according to the natural brightness in one day and the brightness people need in various environments. At present, the production technology of most of solar cell modules can ensure that the performance of solar street lights will not decline for more than 10 years; solar cell modules can generate electricity for 25 years or longer. The maintenance cost of solar street lights is low. In remote areas which are far away from cities and towns, the maintenance or repair of conventional power generation, power transmission, street lights and other equipment is very expensive, while solar street lights only require periodic inspections, and their maintenance costs are less than conventional power generation systems. Compared with conventional street lights, solar street lights are safer, because they are ultra-low voltage products. Solar street lights use low voltage, the power generation effect is stable, there is no need to consider the hidden dangers such as electric shock or fire, and there is no need to consider the problem of circuit design, as long as it is installed as required. Solar energy, the energy source of solar street lights, is a kind of renewable and environmentally-friendly energy. It is endless and does not pollute and radiate the environment. Solar street lights use no fuel to operate and work purely on solar energy. Solar energy is unlimited and imperishable and is the perfect green lighting solution. Non-renewable energy sources like coal, gas, oil, etc. can eventually run out. People are becoming conscious about the fact that the use of solar lights helps in reducing the carbon footprints of individuals, homes and businesses. If solar street lights are used in residential quarters, it can reduce property costs and also reduce the cost of owners. Moreover, solar street lights are easy to maintain and do not require electricity, so it is more cost-effective than conventional street lights. Solar street lights only need to be invested once. Generally, the investment cost can be recovered in two to three years and users can obtain the profits. Solar lighting technology has evolved over the years. Researchers and scientists are still working towards making the solar panels more effective. In the future years, solar panels costs are expected to be less expensive.

Commercial Application of Solar Street Light Solar street lights are fast growing in popularity all over the world. Not only solar street lights are inexpensive mediums of lighting up the roads, but they are also sustainable and environmentally-friendly. Each solar street light system consists of several core components. A modern solar street light has embedded solar panel, inbuilt lithium-ion batteries, battery management system, night and motion sensors as well as automatic controls. The fully automatic device comes with LEDs, inbuilt and replaceable Lithium-ion battery and passive infrared (PIR) sensors. A typical solar street light is weather-proof and water-resistant, has low insect attraction rate and low glare and has a longer life. This is why people consider using solar street lights to their advantage and do their part to conserve energy, optimize your off-grid system and decrease your costs, such as maintenance and monthly electricity bills. (Mexico installation case) Thanks to advances in solar panel, battery, and LED technologies, commercial solar outdoor lighting is now more reliable than its grid-tied counterparts, and it provides a higher quality of light for a lower cost. Indeed, the cost of solar outdoor lighting has benefitted from synergies in technological innovation in three key areas: Reduced cost of solar panels: In recent years, the cost of photovoltaic panels has dropped precipitously. Improved battery technology: The growth in the hybrid and electric car markets has improved battery technologies and as a result, compact, highly efficient, longer-lasting rechargeable batteries come out. Improved LED efficiency: LED lighting is also gaining in efficiency, which translates to more light with less power, or greater efficacy (more lumens per watt), which equates to a reduced cost for the same lighting output. As a result of these trends, commercial solar outdoor lighting is now more economical than grid-tied options in many situations. These include situations in which the existing electrical infrastructure is remote or nonexistent, such as perimeter security and greenfield construction, or in which there is a reluctance to disturb the existing paving or landscape — i.e., parking lots, roadways, outdoor storage areas, parks and trails, playgrounds, and campuses. Solar street lights are beneficial for the lighting needs of parking lots and parks as they help to illuminate signs, pavilions and trails. Many airports are powered with solar LED lights at their runways for safe aircraft operations. Stadiums can also be powered with commercial solar street lights to provide high power lighting during cricket or football matches at night. Solar street lights are also being placed on national highways, port terminals, truck rest points, warehouses, industrial and construction sites, rural areas and other municipal applications. Since solar street lights are independent of the grid and with no electricity cost, they can be installed easily in a remote street or highway where there is no access to grid electricity. Commercial solar street lights require no external wires or trenching for their installation and need only minimal upkeep. Therefore, installation and maintenance costs will be lower when compared to conventional street lights. Most often, authorities and civic sources hesitate to implement outdoor lighting systems due to budgetary restrictions. Since solar energy is free and available in abundance, solar street light is a cost-efficient long-term investment. Commercial solar street lights operate automatically with dusk to dawn feature and do not need any type of manual intervention to switch on or switch off the lights. The lights should be installed in a shadow-free area where the panels can receive direct sunlight throughout the day. Road Smart’s solar street lights are engineered to a commercial grade, built to last the test of time and practically maintenance free. Installation is typically quick, easy and often at a lower cost compared to expensive electric cable trenching. We spare no effort to produce high-quality solar street lights and provide excellent service for customers. (Singapore installation case)View Detail

Smart Solar LED Street Light Design Scheme Solar street light consists of solar controller, light source, solar panel, battery, light poles, and other components. In the design, we should pay attention to the following issues. 1. Solar street light system controller. Usually, a solar charge and discharge controller have functions such as overcharge protection, over-discharge protection, light control, time control, and anti-reverse connection. However, a better solar controller is more than that. For example, the solar controller we developed for our street lamp not only have above functions, but also can achieve single-string charge technology, dual-route control technology, MPPT technology, smart control technology, etc, which enable street solar lights higher intelligence and more stable. 2. The choice of the light source. According to the actual needs of the lighting situation, the appropriate power and light source should be selected. Based on recent years' practice and the development of LED, energy-saving and environmentally-friendly LEDs are now commonly used as light sources. Led power for rural road and city street lighting is generally 10 watts to 80 watts. 3. Selection and configuration of the solar panel, which must be determined according to the power consumption and solar radiation conditions. There are big differences in sunshine conditions between different regions. The design of the bracket which connects solar panel and lamp body is also important. The optimal inclination angle and wind resistance design should be considered during the selection. 4. Selection of the battery. The calculation of the design capacity of the battery is simpler than the peak wattage of the solar module. According to the daily power consumption of the load, and the rainy days that require continuous load, plus the first night's work, the battery capacity is reasonably determined. Besides, it should be noted that a higher quality solar street light usually adopts lithium battery for its advantage such as high energy density, good safety performance, long cycle life, clean and pollution-free. 5. The surface treatment of solar street light poles. The general requirement is hot-dip galvanized spraying. Such a lamp pole has high self-cleaning, corrosion resistance and aging resistance, and is suitable for any climate environment.

Design An Off-grid Solar Power System Solar energy is the most abundant of all renewable energy resources and can even be harnessed in cloudy weather. Nowadays more and more people are turning to solar. Some are considering to install off-grid solar power system. A complete off-grid solar power system has all the necessary equipment to generate, store, and supply solar energy onsite. As off-grid solar power systems operate without a connection to any external power source, they are also referred to as stand alone solar power systems. Off-grid solar power systems are ideal for remote rural areas and applications where other power sources are either impractical or are unavailable to provide power for lighting, appliances and other uses. An off-grid solar power system is made up of several key components. To be truly off-grid, your system needs to have batteries to store the energy you generate. It will also need solar panels to generate energy and some other equipment to bring it all together. A typical off-grid solar power system design will look something like this: 1. Solar panels and mounting kits for roof or ground mounting.2. Power inverter to turn DC current stored in your batteries into usable AC current.3. Charge controller to manage solar energy conversion.4. Batteries to store the energy you generate.5. Monitoring system so you can manage power generation and usage.6. Cables, fixtures and fittings. So, how to design an off-grid solar power system for your own need? This article will talk about it and offer you some information. First, calculate your total electricity needs This is one of the most important steps you can take to ensure you will not waste your money on an oversized system or end up with a system that isn’t able to sufficiently meet your energy need. In order to correctly determine the energy need, you can use a load calculator or work directly with professional personnel. Enter each appliance you will be powering with your energy system, how often you use it per day, as well as the appliance’s relevant specifications. Try your best to remember every appliance you will be using with your power system. Second, determine the number of solar energy storage batteries you will need. You will need to figure out how many batteries you need to properly store all of that energy as well as meet your power and current energy needs. During this process, make sure to ask yourself questions like whether you only need enough storage for a day or two, or if you need to have enough storage for more days. Besides, the battery types should be taken into consideration, too. Among the few major battery types, the most advanced option today is the lithium-ion battery, which packs more energy capacity per unit volume, and also offers some other pros such as greater safety and reliability. Thrid, determine the number of solar panels. After you know how much energy you need to produce per day from your load calculations, you need to calculate how much sunlight will be available for you to harvest from, otherwise known as “sun hours.” The number of “sun hours” is determined by how many hours the available sun in a given location shines on your panels at a specified angle throughout the day. Then, you need to select your solar charge controller and solar inverter. A solar charge controller is a device that regulates current between your solar panels and the batteries. Its job is to ensure a smooth current between panel and battery and to ensure batteries are not overcharged. The final major piece of off-grid power system design is selecting a solar inverter. An inverter’s job is to turn DC energy stored in your batteries into AC power. As a general rule, to run a home that is constantly in use, we suggest you to use a pure sine wave inverter. The above is about how to design your own off-grid solar power system. Hope you will learn something from this article.View Detail

The Characteristics of Solar Street Light Battery The common storage batteries are divided into four types. The gel battery is like the upgraded version of lead-acid battery. Compared with lead-acid battery, it doesn’t need maintenance. There is colloid electrolyte instead of sulfuric acid electrolyte inside the gel battery. It performs better than lead-acid battery in storage capacity, discharge capacity, safety and service life. It can adapt to low-temperature environment such as the cold northern region. The gel battery is shock-resistant and can be used in severe environment. The service life is double or even more than that of ordinary lead-acid batteries. The battery lead plate of lead-acid battery is made from lead and lead oxide. There is sulfuric acid electrolyte inside the lead-acid battery. The biggest advantage of it is stable voltage and low cost. Ternary lithium ion battery has a lot of advantages. It features high specific energy, small size and fast charging. But its price is high. Its deep cycle times are about 500-800 times, and its life span is similar to that of gel batteries. The temperature range for use is -15℃-45℃. Lithium iron phosphate battery also has many advantages. It features higher specific energy, small size, fast charging, long service life and stable performance, but the price is the highest of all storage batteries. The solar street light is safe and durable. There may be potential safety hazards during the using process of traditional street light due to poor construction, aging of materials and power outage. Instead, the solar street light converts the low-voltage direct current into electricity. Therefore, there will be no potential safety hazards when using the solar street light. The installation is flexible and convenient, which is convenient for users to choose and adjust the capacity of solar street lights depend on their own needs. The off-grid solar street lights is more independent and flexible in acquiring the power. The solar street light will be directly affected by the weather conditions. Continuous cloudy and rainy days will affect the lighting. As a result, the street light will fail to meet the the illuminance requirements of national standards, or even fail to turn on. The lighting time may be too short at night due to insufficient light during the day. It is difficult to maintain solar street lights. The heat island effect of the solar panels cannot be controlled and detected. The service life cannot be guaranteed. The illumination range is narrow. The currently used solar street lights have been inspected by the China Municipal Engineering Association and measured on the spot. The general illumination range is 6 to 7 meter.View Detail

The Classification of Solar Lighting Solar lighting uses solar energy as energy, realizes photoelectric conversion through solar panels, uses batteries to store electricity during the day, and supplies power to the light source through the solatr controller at night to achieve functional lighting. As we continue to move towards renewable energy sources, solar street lighting becomes an ever increasing and popular choice on the market. Taking away the need for power from the grid, these self-sufficient devices are able to capture the energy of sunlight. This powers a rechargeable battery inside that runs a lamp throughout the entire night. Solar street lighting is traditionally fitted on a raised platform to optimise the amount of sun exposure. Photovoltaic (PV) panels are either mounted alongside the light or connected within the pole to capture said sunlight. In essence, the unit becomes mostly self-sufficient and provides a host of benefits for users. Solar engineering lighting 1.According to the lighting power: The lighting power ranges from 10W to 200W. The application scenes range from rural roadways to highways and other roads. At present, the most common one is the 6-meter solar street light used in new rural areas. 2. According to the product characteristics of different manufacturers, solar engineering lights can be divided into split solar street lights, solar panel lights, and all-in-one solar street lights. In China, low-end split solar street lights still dominate the market; in foreign countries, solar panel lights are more popular due to logistics costs and ease of installation. Solar civil lighting 1.From the aspect of use, solar civil lighting can be divided into functional lighting and decorative lighting. When people look for functional lighting, they will pay more attention to the brightness and effect of lighting (such as continuous lighting); it is more suitable for areas with a lack of electricity or low electricity, or areas that require brightness. These areas are mainly concentrated in Southeast Asia, Africa, or rural areas. When people look for decorative lighting, they will pay more attention to the contrast of the atmosphere, and attaches great importance to the integration of lights and the environment, so there are relatively high requirements for the shape of the product and lighting effects (light direction, light type and color temperature, etc.), and there are certain requirements for brightness. It is more suitable for urban or more developed countries; 2.From the aspect of main light types and application scenarios, solar civil lights is divided into flat panel lights, flood lights, post lights, solar household lights (both indoor and outdoor), wall lights, lawn lights, buried lights, other garden lights, etc. Solar lighting solutions have a long-term good impact on the environment, help shape urban and rural neighborhoods, and promote the economic and social development, in addition to many other advantages such as cost and performance. Going solar is a means for public stakeholders to deliver a better service than simply “switching to green energy.” Related Articles:Road Smart IoT Intelligent Solar Street Lighting System IntroductionRoad Smart Medium-high Efficiency Solar Street Light AdvantagesThe Characteristics of Solar Street Light Battery Tags:Solar Street Light Solar Energy Storage Solar PanelView Detail
