Solar streetlights are a popular choice for public street lighting due to their energy efficiency and sustainability. However, choosing the right LED chips is crucial for the performance and longevity of the lights. In this article, we will discuss the importance of selecting the right LED chips for solar streetlights.
First, let’s see the Solar Panel Selection for LED Street Lights.
Solar panels are the backbone of solar streetlights. The efficiency and size of the solar panel have a direct impact on the performance of the lights. When choosing a solar panel for LED street lights, it is important to consider the efficiency of the panel. Higher-efficiency panels will produce more power and require less surface area to generate the same amount of energy.
For example, a 300-watt solar panel with 20% efficiency will produce more power than a 350-watt solar panel with 15% efficiency. Additionally, the size of the solar panel should be determined based on the lighting requirements and location of the street lights.
How about the Wattage for Solar Street Lights?
The wattage of solar street lights is an important factor to consider as it affects the brightness and duration of the lights. The ideal wattage for solar streetlights depends on the location and lighting requirements. For example, a street with heavy traffic and high lighting requirements will require higher wattage than a residential street with low lighting requirements.
Calculating the wattage needed for solar street lights can be done by considering the required brightness level, the location of the lights, and the number of hours of operation needed. For instance, a residential street with low lighting requirements may only need a 50-watt solar street light, whereas a commercial area with high lighting requirements may require a 150-watt solar street light.
What do you need to consider when you are designing a Solar Street Light System?
Designing a solar street light system involves selecting the right components and designing a system that is efficient and durable. The key components of a solar street light system include the solar panel, battery, LED chips, and controller.
When designing a solar street light system, the solar panel should be sized based on the wattage of the LED chips and the location of the lights. The battery should also be selected based on the wattage of the LED chips and the number of hours of operation needed.
For instance, if you are designing a solar street light system for a public street lighting area that requires 12 hours of operation per night, and you have chosen 30-watt LED chips, you will need a solar panel that can generate enough power to charge the battery during daylight hours and support the LED lights for the entire night.
Based on the efficiency and size of the solar panel, you may need to choose a battery with a capacity of 100-120 Ah to ensure optimal performance. The size and capacity of the battery will also be influenced by other factors such as temperature, the number of days without sunlight, and the charging and discharging efficiency of the battery.
In conclusion, choosing the right LED chips for solar streetlights is crucial for the performance and longevity of the lights. Factors such as solar panel selection, wattage, and system design should be considered to ensure the system is efficient and effective. By selecting the right components and designing a quality system, solar street lights can provide sustainable and reliable lighting for public areas.
Here comes the most important part: Lumens per watt for solar LED Street Lights.
When choosing LED chips for solar streetlights, it’s essential to consider the lumens per watt (lm/W) ratio. Lumens per watt refers to the efficiency of the LED chips in converting electricity into light. The higher the lumens per watt ratio, the more efficient the LED chip is, and the less energy it will consume. For outdoor solar street lights, an optimal range for lumens per watt is between 130 and 160 lm/W.
If you need to illuminate a street with an area of 100 square meters, you’ll need a minimum of 10,000 lumens. With an LED chip with lumens per watt ratio of 130, you’ll require around 77 watts. However, with an LED chip with lumens per watt ratio of 160, you’ll require just over 62 watts, saving you energy and costs.
Then how to Calculating Battery Capacity for Solar Street Lights?
Calculating the required battery capacity for solar streetlights is crucial to ensure reliable and long-lasting performance. The battery capacity required depends on factors such as the location of the solar street light, lighting requirements, and weather conditions.
One of our customers need to power a solar street light that requires 100 watts of electricity for 12 hours per night and there are three rainy days in a row, you’ll need a battery capacity of at least 100 x 12 x 3 = 3,600 watt-hours (Wh). It’s important to factor in a safety margin of 20% to 30% to ensure the battery can handle unexpected power demands.
After the technical information, let’s see what the equipment and Components for Solar Street Lights need.
To design an efficient solar street light system, you’ll need to understand the key components and equipment required. These include solar panels, batteries, controllers, and LED chips.
Eg.
A typical solar street light system might include a 100W solar panel, 50Ah battery, 10A controller, and 30W LED chip. The solar panel converts sunlight into electricity, which charges the battery. The controller regulates the flow of electricity from the battery to the LED chip, ensuring optimal performance and preventing damage to the battery.
The Voltage and Materials in LED Solar Street Lights:
LED solar streetlights use direct current (DC) voltage, typically 12V or 24V. The lower voltage is safer and more efficient than high-voltage alternatives. The materials used in LED solar street lights should be durable and efficient, capable of withstanding harsh outdoor conditions.
For example, LED chips should be made of high-quality materials such as gallium nitride (GaN) or silicon carbide (SiC) to ensure maximum efficiency and longevity. The solar panel should use high-efficiency photovoltaic cells and a durable frame to withstand wind and weather. The battery should use high-quality materials such as lithium-ion (Li-ion) or nickel-cadmium (NiCd) for optimal performance and lifespan.
In conclusion, solar street lights offer an eco-friendly and cost-effective solution for outdoor lighting. However, choosing the right LED chips is crucial for ensuring optimal performance and efficiency. Factors such as solar panel selection, wattage, battery capacity, equipment and components, lumens per watt, voltage, and materials must all be considered when designing a solar street light system.
By taking these factors into account and selecting high-quality LED chips, it is possible to create a solar street light system that provides reliable and long-lasting lighting for public areas.
Remember to consult with a professional or experienced vendor to ensure the best results. With the right combination of components and careful design, solar street lights can be a great solution for outdoor lighting needs.
