How to choose the right solar street lights for your driveway, yard, rural roads, or urban streets? The solar street light industry is deep, and picking the wrong one can lead you into a trap.
First off, I need to set the record straight; the so-called 1,000W, 2,000W, or even 500W online are all misleading, as current industry technology cannot achieve that. Typically, only tower cranes, rooftops, and other high-rise facilities use a few kilowatts of electricity. Installing a 1,000W light fixture at home is like having a small solar panel, as the fixture can be used for grilling. Moreover, looking at a 1,000W light fixture for even a brief moment can cause dizziness, and prolonged exposure can lead to blindness. So, don't believe the claims of hundreds or thousands of watts; they're just fooling you.
Let's get back to the topic at hand. Many people are unsure how to choose solar-powered lighting fixtures; they simply believe that more surface LED beads are better, and the higher the rated watts, the brighter the light. However, this is not the case. This misconception has been fostered by some merchants engaging in false advertising. In fact, when purchasing solar street lights, you can ask the following questions: the actual power of the lamp (if it's several kilowatts, there's no need to discuss it), the battery capacity, and the size of the photovoltaic panel. Asking these questions will generally prevent you from being deceived.
Firstly, the wattage: The wattage of solar lighting is not determined by the LED beads, but by the controller! The controller acts like the human brain, transmitting signals to make your hand exert force. The lighting adjusts brightness through the controller. If the controller's power rating reaches 50W, the lighting can also shine at 50W. However, controllers are typically housed within the lighting fixture. Whether you can purchase a controller with full power depends on whether the seller speaks the truth or not.
Next is the battery: The battery for solar lighting is also a science. We mentioned before that there are two types of batteries, lithium iron phosphate, and ternary lithium batteries. These, like controllers, are things you can't see, so it's even more important to ask the right questions. First, ask what type of battery is used, and then ask about the voltage, such as 3.2V, which is commonly used for daily operations, or 12V, although the latter is more for custom engineering orders. If you're buying a home light and they tell you it's 12V, you can say goodbye to that. Generally, 12V is used at heights of about ten meters, and installing it at home at three to four meters with 12V is almost like trying to overcharge you, because you can't tell the difference. (The 12V battery is four to five times more expensive than the 3.2V battery, and also four to five times larger.) If you have someone custom order it, then disregard my advice. Here's a picture for reference: on the left is a 3.2V battery, and on the right is a 12V battery, both with the same Ah rating.
Just solar panels: When purchasing, remember not to ask for how many watts, but rather ask for the size directly, like a 50W solar panel's size is 670*530mm. This size cannot be changed; if the same size is offered with a different wattage, congrats, you've been scammed (if you want to know more sizes, leave me a message here; I won't list them all out).
Next up, let's delve into the topic: How to choose suitable and practical solar street lights to avoid being scammed!
Firstly, for outdoor use, LED lighting is mostly used now, and the brightness is quite good. Don't worry about choosing the right one; as long as it's not a few dollars, the brightness is fine. Mainly consider how large an area you need to illuminate and how long you plan to use it. If your yard is large and requires more light, buy a model with a larger battery and solar panel, don't focus on the fixture! Solar panels are usually matched with the battery. If the power isn't sufficient, there's no need for a large solar panel, as the item still requires costs. Generally, spending a bit more will ensure better components, and using higher-quality batteries and solar panels can extend the lifespan to three to five years. If you solely chase the price, you're likely to end up with subpar products. Personally, I think if you're going to buy, buy something better; if not, don't buy at all. Buying something that doesn't work well is not just a waste of money but also frustrating.
Village and town roads are generally about 5-6 meters wide, with the main roads being around 10 meters. In this case, the height of your lamp post is what matters. We commonly use 6-meter posts, so I'll explain based on that. A 6-meter lamp post can be chosen based on the spacing. If your lamps are closely spaced, smaller, lower-wattage fixtures can be used. If there's a lamp every 50-60 meters, brighter lamps are definitely needed. Typically, a 6-meter lamp post with a 50W light source is sufficient (for information on battery and solar panel sizes, please leave a message here, no examples will be given). If unsure how to judge, here's a simple trick: look at the illuminated area. Place the fixture about 6 meters away and see how far it illuminates. A 50W fixture usually covers a distance of about 30 meters without any dark spots. If the distance isn't reached, it indicates an issue with the fixture. (The image shows a 30-meter spacing with no dark areas.)
Most city road projects are contracted by construction companies, who provide drawings and specifications for lighting fixtures. Pricing depends on the client's requirements, and some are publicly bid. However, these also come with drawings, so you just need to quote and bid based on the drawings.
