Solar street lamps driven plate with the working principle of solar cells

We all know solar street light; The brain; And the important role of solar controller. So, solar street light to stable work, a powerful brain alone are not enough. Today, we have to chat is really stable electricity - the output of the parts Battery

we all know that the solar street light. The brain; And the important role of solar controller. In this case, the powerful brain enough for solar street light stability. Today, we will discuss the battery, it is really stable power output component. Why it is necessary to configure solar panels power battery? This is because the photovoltaic power generation system is not as stable as we thought. In order to prevent the input energy load loss caused by unstable, the configuration of the battery is very necessary. Ordinary battery including the sealed lead-acid battery, solar street lamps ordinary lead-acid battery, gel battery, lithium iron batteries, alkaline nickel cadmium battery, etc. Voltage is usually 12 v or 24 v. The development and application of lithium batteries also provides many possibilities to reduce the component configuration is empty. Since the battery is so important, the bigger the capacity, the better? In order to clearly understand this, we must review its working process. The battery at night was the first thing you should do and rainy days to load power supply equipment. On the other hand, it should be stored panels generate electricity during the day. If the capacity is very big, the battery discharge process will take longer than charging process, lead to continuous power loss. Large capacity, of course, also a lot of waste. Based on this, battery capacity should be carried out according to the actual load matching. In general, 4 ~ 6 times higher than ordinary power load, the battery voltage is lower than 20% ~ 30% of solar panels. With the progress of technology, cell type and performance have greatly improved. Battery solar street lamps have high circulation cycle count, low self-discharge rate, long service life, deep discharge capacity, high charging efficiency, etc, basically can be less maintenance or free maintenance. As a powerful storage battery as a power supply, solar street light another role will appear, the light source. The next issue we will discuss with you the solar street lamps light source.
