Comparison Test: Solar Lights Battery With or Without Protection Board

By |2022-04-12T09:52:32+00:00April 12th, 2022|Technical Support|

As we know, solar lights are used in outdoor applications. They charge under sunlight and discharge during the night automatically, without any human intervention during their ordinary operation. What if the sunlight is very strong causing the battery over-charged? What if many rainy days last making the battery over-discharged? The battery is easily damaged under over-charged/discharged conditions. As a result, it is very important to have the battery protection board built into the solar lights battery pack, so that they can operate normally. What is the battery protection board? The battery protection board is a circuit board that can protect the battery pack. It is mainly composed of electronic circuits like control IC, MOS swifts, capacitors, resistors, and so on. When the cell current or voltage exceeds its rated value, the battery protection board can immediately swift off to keep the cell in safety. What is the function of a battery protection board? 1) Overcharge protection When a certain voltage is reached which exceeds the rated safe voltage, it will stop the battery charging. 2) Over-discharge protection When the battery voltage drops to a certain voltage that is lower than the rated safe voltage, it will stop the battery from discharging. 3) Overcurrent protection When

5 Reasons to Use Solar Lights for Security

By |2022-03-19T08:42:12+00:00March 19th, 2022|Newest Articles, Technical Support|

Nowadays, LED solar lights have been gaining popularity due to their flexibility to be installed in even remote areas without an electrical power supply. The solar lights' lighting output can bring safety and security to residents. There are 5 advantages to implementing led solar lights into people's daily life. 1. Reduce potential hiding places or dark areas while people are passing by. Solar lights can enhance safety for pedestrians by lighting up the pathways/parks/parking lots, where there may be some risks of hurting people. For example, puddles, broken glass, big obstacles, etc. 2. Being awared from a distance whether anyone or animal is moving or not. Most solar lights work with motion sensor functions. The solar lights will operate 100% brightness when something moves in the sensing area. Once the motion is detected, it lasts for a few seconds with the best brightness, so that people can have clear visibility of what's moving in that area. Provide clear visibility of areas from a distance to see anyone moving in or around the area. 3. Provide assistance to safety devices such as cameras in the area. When there is movement in the area, the solar light will provide higher

Vital Factor to Solar Panel Quality: Low Light Performance

By |2022-02-25T07:56:03+00:00February 25th, 2022|Newest Articles, Technical Support|

With the booming solar photovoltaic industry, more and more people are using solar systems in their homes, or solar-powered items in daily life, like solar-powered heaters, solar garden lights, etc. Sometimes, people will focus on the solar panel quality as they want more lighting at night, as a better solar panel enables more energy stored in the batteries, which can ensure long-lasting time. It is well known that the power of the solar panel is a vital factor to decide the solar panel quality. The wattage is higher, the working current is higher, the charging efficiency is better. Most people choose solar panels by comparing solar panel power. However, if we dig inside the discharging characteristic of the solar panel, we will find that solar power is one of the factors that affect the solar panel quality, but not the only one. Here is an example: Assume that we have two solar panels A & B, they are all with the voltage 6V, power 30W, theoretically their charging performance is same. But is it correct? Based on an ideal algorithm, within a standard sunshine daytime, the rated output current is I=30W/6V=5A. However, it will never get a constant 5A current through the whole day.

What is the real power of solar lights?

More and more people prefer to buy solar lights for their gardens, backyards, patios. LED solar lights are widely used in people’s houses. At the same time, there are much more shops online selling different kinds of led solar lights. There are solar street lights, solar floodlights, solar garden spike lights for options. However, there is one main doubt that exists when people are buying solar lights: What is the real power of solar lights? It is very common that people find the same lamps with super different powers. Take this lamp as an example, some shops are selling it in 60w, some are selling it in 200w, but they are the same in size and even have the same qty of LEDs chips inside. Is the 100w better than the 20w one? Why is the 100W selling at a lower price than the 20W one? In the market, the solar light power marked at no generic standard creates so much confusion for people who are trying to buy solar lights online. What’s worst is that most people can’t test the real power of solar lights without professional electrical knowledge of the solar

How to make the solar lights batteries work longer?

By |2022-02-26T06:17:17+00:00January 8th, 2022|Newest Articles, Technical Support|

Nowadays, solar lights are becoming more widely used whether in rural or urban areas. Solar lights use green and renewable energy, they absorb power from the sun and convert it into electricity stored in batteries, then discharge to the led light when the solar light works. However, some people are still worrying about problems that may happen when using solar lights, one of the reasons is that they think it is a headache to change the batteries after 2-3 years of use. How to make the solar lights batteries work longer? Here are some tips: Avoid the batteries being overcharging. The lifespan of the solar light battery is closely related to the heat accumulation generated inside the battery, and the heat source inside the battery mainly comes from the power loss of the internal electrochemical reaction. In the oxidation reaction, the float current will increase to generate more heat. During constant voltage charging, the float current will increase with the temperature rise, which will further increase the temperature. If the batteries are being overcharged, the high temperature will bring serious harm to the batteries, such as battery water loss, shell "bulging", In severe cases, the battery will be scrapped. To prevent overcharging,

Solar Street Lights – Avoid Wasting Energy In the City

By |2022-02-26T06:17:10+00:00November 10th, 2021|Technical Support|

Solar street lights are lighting devices that transform solar radiation into electrical energy through photovoltaic solar panels during the day. This energy is stored in batteries so that when its use is demanded at night the streetlights are turned on. The components of the solar street lights are the following: 1- Photovoltaic solar panels: they are responsible for capturing and transforming the Sun's energy into electricity. 2- Batteries: they are in charge of storing the energy captured by the Sun. 3- Control plates: they are used to manage the switching on and off of the luminaires. They automate the use of the solar street light to avoid unnecessary costs of the energy produced. 4- Lamps: they transform the energy stored in the battery into the light. Advantages: Solar street lights have a series of advantages over conventional street lights, among which the following stand out: 1- They are independent of the electrical network, so the operation and maintenance costs are lower. 2- They feed on a cheap and inexhaustible source of energy. 3- They can be installed in isolated places even if the power grid does not reach them. 4- Reduces the risk of accidents as there is no wiring. Currently, more and more
