With the gradual development of society, streetlights serve not only as a source of illumination but also as a canvas for design elements added by more designers. However, considering that a significant portion of China still comprises rural areas, installing streetlights can present various challenges. Rural households are dispersed, making collective electrification quite difficult. The emergence of solar streetlights has alleviated this awkward situation, providing solutions by directly converting solar energy into electrical power. What should users be aware of when purchasing solar streetlights? Here is an introduction from Century Sunshine Lighting.
Key considerations when purchasing solar streetlights:
First, consider the wattage: The wattage of solar lighting fixtures is determined not by the LED beads but by the controller! The controller acts like the brain, transmitting signals to your hands to exert force. The fixture adjusts its brightness based on the controller. If the controller’s power can reach 50W, then the fixture will indeed illuminate at 50W. However, the controller is typically housed within the fixture, so whether one can find a controller of sufficient power depends on the honesty of the seller.
Next, consider the battery: The battery for solar fixtures is also a specialized area. There are two types of batteries—lithium iron phosphate and ternary lithium batteries. Like the controller, these are usually not visible, so it’s crucial to inquire clearly. First, ask which type of battery is being used, and then inquire about the voltage. In normal situations, batteries operate at 3.2V, while there are also custom engineering applications at 12V. If you are purchasing a home-use lamp and someone offers you a 12V option, you should walk away. Generally, 12V is used at heights of about ten meters; installing it at a height of three or four meters would be an attempt to overcharge you, as you likely won’t notice the difference. (The price of a 12V battery is approximately four to five times that of a 3.2V battery, and their sizes differ significantly.) If you are customizing specifically for someone, then disregard this advice.
Lastly, consider the photovoltaic panel: When purchasing, remember not to ask about wattage; instead, directly ask about the size. For instance, a 50W photovoltaic panel has dimensions of 670*530mm, a size that cannot be altered. If a seller provides you with a different wattage while using the same dimensions, you are likely being deceived.
