How to extend the lifespan of solar streetlight batteries?

First, it is important to avoid overcharging. The lifespan and performance of solar streetlight batteries are closely related to the thermal buildup inside the battery, which primarily comes from the power loss during internal electrochemical reactions. This can be simply observed by looking at the product of charging voltage and charging current. In the oxygen recombination reaction, the float charging current increases, generating more heat. During constant voltage charging, the float charging current also increases with rising temperature, further raising the temperature. Thermal runaway is a unique phenomenon caused by the structural design of valve-regulated sealed batteries. Thermal runaway can lead to serious issues such as battery dehydration and bulging of the casing, and in severe cases, it can render the battery unusable. To avoid overcharging, it is essential to strictly adhere to the charging voltage values provided in the manufacturer's manual. Current combined power sources can be set up and managed intelligently; it is important to first set them correctly and secondly ensure that unauthorized personnel do not change them casually.

The role of monitoring poles and the characteristics of monitoring poles.

The role of monitoring poles and the characteristics of monitoring poles.

We all know that monitoring poles play a significant role in our lives. Because of this, we need to pay attention to many issues during the construction of monitoring poles. Not only should we produce high-quality monitoring poles, but we also need to ensure everyone's safety. Next, let me introduce the effects of monitoring poles in our lives.

Work that needs to be done well when installing solar street lights

Work that needs to be done well when installing solar street lights

The hoisting and positioning of solar streetlight poles (especially high poles) is a key project in the installation of solar streetlights. The planned pole positions are mostly determined by calculations, but on-site, there may be situations where the actual positions of the solar streetlight poles do not match the plans, requiring adjustments on-site. Additionally, it is important to assess whether the construction site is suitable for the entry of transportation and hoisting vehicles, whether the hoisting equipment can be positioned for work, and whether there are power outages or temporary traffic interruptions. Only through on-site inspections can a feasible hoisting plan be developed.

The reason why solar street lights do not light up during continuous rainy days.

The reason why solar street lights do not light up during continuous rainy days.

Solar street lights: As the name suggests, they use solar energy to provide electricity for street lights. During the day, solar street lights use solar panels to convert solar energy into electrical energy, which is stored in batteries through a solar street light controller. At night, the controller manages the power supply from the batteries to the light source. Recently, many regions across the country have experienced continuous rainy weather. In such conditions, the efficiency of converting solar energy into electrical energy is very low, even to the point of no energy conversion. So how can we ensure power supply to the light source? What are the main reasons for solar street lights not lighting up during continuous rainy days?

The advantages of solar street lights compared to ordinary lighting street lights.

The advantages of solar street lights compared to ordinary lighting street lights.

Solar energy is recognized as an excellent alternative power source. Its use helps reduce CO2 emissions, thus achieving the goal of environmental protection. Many countries, such as Denmark, Finland, Germany, and Switzerland, consider climate change to be a major factor driving the research, development, and sale of solar energy. In countries like Austria, initiatives to build collectors independently have promoted the active development of solar energy equipment. Norway has installed over 70,000 small photovoltaic systems, with about 5,000 new installations each year, mostly in remote towns, mountainous areas, and coastal resort regions. Finns also purchase several thousand small (40-100W) photovoltaic systems annually for their summer cottages. Additionally, some countries are making efforts in the commercialization of high-performance solar power windows, solar water heaters, energy storage devices, transparent insulation materials, daylighting solutions, and building-integrated photovoltaic systems.

The installation process of solar street lights.

The installation process of solar street lights.

Open the box containing the solar panels, place the solar panel on the cardboard on the ground to receive sunlight, then align the holes of the solar panel bracket (if the holes of the solar panel are too small, use a drill bit to enlarge them). Use bolts with washers, pass them through the holes, then add washers and tighten the nuts. Use two 17mm wrenches to tighten all four bolts.
