6 things you must know about commercial solar street lights

   Why use commercial solar street lights?

Commercial solar sign lighting is essential to maintaining 24/7 visibility for your business, whether you're retrofitting an existing lighting system or installing a new one, opting for solar lighting has the same benefits as the lighting they provide obvious.

1. Electricity bills keep going up, whether your business is big or small, new or old, the savings are earned.

2. Solar power is free, don't think you need to live where the sun shines. This is a common misconception, and one need only look at New Jersey, the second largest consumer of solar energy in the US, to see that you don't need to live in a desert to use the sun's energy efficiently. Saving money on traditionally using electricity for business sign lighting is just the first way solar power can boost business profits.

 3. Easy to install, unlike traditional grid lighting, solar lighting is easy to install with little or no electrical knowledge and can be done by almost anyone with just a few simple tools. This means business owners can avoid the high cost of hiring contractors to do the complex electrical work associated with traditional lighting, which is required to comply with local building codes and insurance regulations.

5 key elements that determine the quality of solar street lights

1. Photovoltaic panels

The photovoltaic panels determine the brightness of the lamps. First of all, the light source needs enough electricity to drive. The 1W light source needs about 300mAH of electricity to light up for 1 hour. When your photovoltaic panel can input enough power to the battery, the battery can provide enough power to the light source, and the lamps can be set according to the setting. When your photovoltaic panel can not input enough power to the battery, the battery can not provide enough power to the light source, and the brightness of the lamp will dim.

So what kind of photovoltaic panels should be used? First of all, the photoelectric conversion rate of photovoltaic panels should be high. At present, the photoelectric conversion rate of polycrystalline silicon cells (the main material of photovoltaic panels) in large-scale production can be achieved > 18%, and the photoelectric conversion rate of photovoltaic panels used in solar lamps is measured to be more than 17%. The power of the board should be sufficient. What is enough? In a sunny environment, the electricity generated by the photovoltaic panel can fully charge the battery in about 5 hours, which is considered sufficient. The actual conversion rate of the integrated solar street lights produced by ZGSM can reach more than 23%.

2. the battery

The battery plays a major role in the life of the lamp. At present, the life of photovoltaic modules is basically more than 20 years; the life of the light source has also reached 30,000 to 50,000 hours, and the life of 10 years is calculated based on the lighting time of 10 hours per day; the theoretical life of the new ternary lithium battery is 1200 times completely The life of charge and discharge, lithium iron phosphate battery can be charged and discharged more than 2000 times, which is equivalent to a service life of 6-8 years.

3. led light source

The more light sources, the better. The electricity of the solar lamp is supplied by the battery. How much power it can achieve depends entirely on the capacity of the battery. When the battery can only light up 20 watts for 10 hours, whether you have 50 lamp beads or 500 lamp beads, its actual Power can only be up to 20 watts. Anyone who has studied physics knows that the longer the distance of the circuit through which electricity passes, the greater the resistance, and the more lamp beads will only produce a longer circuit. The larger the resistance, the more power is wasted, so the more lamp beads, the more Well, enough is enough.

4. the lamp body shell

The lamp body shell using die-cast aluminum is more durable and waterproof. At present, the shell materials of solar lamps on the market are basically divided into two types: one is a plastic shell and the other is a cast aluminum shell. The cost of plastic housing is low, but it has a short life and poor waterproof performance when exposed to the sun outdoors; the die-casting aluminum housing is durable, has good water resistance, and has good heat dissipation of lamps. We use die-casting aluminum housing for outdoor projects and must It is a thick cast aluminum casing, but the disadvantage is that the cost is higher.

5. Control system

The control system plays a key role in the life of the battery and controls the brightness of the lamps. Here first popularize the functions and functions of the control system. Most solar lamps will have functions such as remote control, light control, time control, full brightness, half brightness, and automatic adjustment, which requires a control system. Due to the limitation of the battery, we know that solar lamps cannot achieve 100% power lighting like the mains lamps, and the capacity of the battery becomes lower in continuous rainy days, and it cannot work as well as when it is fully charged. It needs a The intelligent system intelligently adjusts the output of electricity according to the capacity of the battery, so that the lamp can work in a good working condition to ensure its life. In addition to the basic functions of remote control, light control, time control, full brightness, semi-brightness, and automatic control, the control system we use also requires it to control the input and output according to the real-time capacity of the battery, so as not to overcharge the battery. Over discharge, to protect the battery life and make it more durable.
