A 100W solar high mast light with 4 pieces of 25W lights is a robust outdoor lighting solution designed for illuminating large areas using solar energy. Here's a breakdown of what that entails:
Key Features and Components:
* Total Power Output: The system delivers a total of 100W of LED lighting, distributed across four individual 25W LED luminaires. This configuration allows for good light distribution and coverage.
* Solar Panel: A high-capacity solar panel (or multiple panels) is essential to capture sufficient solar energy. For a 100W lighting system, the solar panel wattage would typically be significantly higher (e.g., 200W, 320W, or more) to ensure adequate charging of the battery, especially on cloudy days and to power the lights for extended periods. The type of panel (mono-crystalline or poly-crystalline) affects efficiency.
* Battery: A robust battery bank, often LiFePo4 (Lithium Iron Phosphate) for its longer lifespan and stability, is crucial for storing the energy captured by the solar panels. The battery capacity (measured in Ah or Wh) determines how long the lights can operate without sunlight. For a 100W system, common battery voltages might be 12.8V or 25.6V, with capacities ranging from 48Ah to higher.
* LED Luminaires (4 x 25W): These are the actual light sources. LED technology offers high efficiency, long lifespan (often 50,000 hours or more), and excellent light output (lumens per watt). They typically have an IP (Ingress Protection) rating of IP65 or IP66, indicating resistance to dust and water.
* High Mast Pole: This is the tall, sturdy pole on which the solar panel, battery, and LED lights are mounted. High mast poles typically range from 6 meters to 30 meters or more, depending on the required illumination area and height. They are usually made of hot-dip galvanized steel or aluminum for durability and corrosion resistance. Some designs allow for the lights and solar panels to be lowered for maintenance.
* Charge Controller (MPPT): An MPPT (Maximum Power Point Tracking) charge controller optimizes the charging process from the solar panel to the battery, ensuring maximum energy harvest and protecting the battery from overcharging or deep discharge.
* Automatic Operation: Most solar high mast lights come with a dusk-to-dawn sensor, automatically turning the lights on when it gets dark and off at dawn. Some systems also include dimming features to save energy during certain hours.
* Mounting Structure: This includes the brackets and hardware needed to securely attach the solar panels, luminaires, and battery to the pole.
Applications:
100W solar high mast lights with 4x25W lights are ideal for illuminating large outdoor areas where grid power is unavailable or expensive, or where an environmentally friendly lighting solution is desired. Common applications include:
* Highways and major roads
* Stadiums and sports complexes
* Industrial zones and factories
* Airports
* Large public spaces and parks
* Parking lots
* Mining sites
* Port areas
Advantages:
* Energy Independent: Operates entirely on solar energy, reducing reliance on the grid and eliminating electricity bills.
* Environmentally Friendly: Reduces carbon footprint and promotes sustainable energy use.
* Low Maintenance: LEDs have a long lifespan, and the systems are generally designed for minimal upkeep.
* Easy Installation: Compared to traditional grid-connected lighting, solar systems can be quicker and more cost-effective to install in remote locations.
* Reliable: Designed to operate in various weather conditions, with sufficient battery backup for cloudy days.
Considerations for Purchase:
* Pole Height: Determine the appropriate pole height based on the area to be illuminated and desired light spread.
* Autonomy: Ensure the battery capacity provides enough backup for desired hours of operation, especially during prolonged cloudy periods (e.g., 2-3 days of autonomy).
* Lumen Output: While the total wattage is 100W, consider the actual lumen output of the LEDs for the desired brightness.
* Warranty: Check the warranty offered on the solar panels, battery, LEDs, and controller.
* Manufacturer Reputation: Choose a reputable manufacturer with a track record of quality solar lighting solutions.
* Certification: Look for relevant certifications (e.g., MNRE, BIS, IEC, CE, RoHS) to ensure quality..
