Another peak of power consumption is coming, and energy conservation naturally becomes a topic that cannot be avoided. How to save energy? Choosing energy-efficient lighting products is obviously an important means.
Don't underestimate this small public lighting(CLASSICLEDLIGHT). According to the data, at present, China's lighting power accounts for about 13% of the total electricity consumption of the whole society. If all the incandescent lamps are replaced with high-efficiency lighting products, the annual electricity saving will be 48 billion kWh. If the whole society realizes the replacement of LED lighting products, it can save about 350 billion kWh per year, which is equivalent to the power generation of four Three Gorges hydropower stations. If you change road lighting to solar street lighting, it is more energy-efficient and environmentally friendly.
"To change a light bulb and change the way we think, we can change the whole world." UN Secretary-General Ban Ki-moon said. A lamp may be insignificant, but the energy gathered can not be ignored. Frugal and healthy, low-carbon life, let's start from now, start from each of us.
When installing public lighting, many friends did not know that the voltage of the battery was 17.5v and the voltage of the battery was 12v. We know that the solar panels are composed of series-connected cells. The voltage of each cell is 0.5v. The 36 cells are 18v. It is generally lossy. The voltage rating is 17.5v, and the voltage rating of the battery is 12V. However, it is about 13v after a full charge. When the battery voltage is lower than 11.6v, it needs to be charged. The battery itself has discharge protection. We know that high voltage can only charge low voltage, and there is a pressure difference before it can be charged. Therefore, the voltage of the panel can charge the battery at around 18v.
In addition, when the system of solar street light is 24v, the solar panel is parallel with two pieces of the same power to charge the 24v battery. The other small series needs to be explained that the total power of the battery board is superimposed, the same power. The series voltage of the battery is doubled and the series current is doubled.
