Solar (or photovoltaic) cells convert the sun’s energy into electricity. Whether they’re adorning your calculator or orbiting our planet on satellites, they rely on the the photoelectric effect: the ability of matter to emit electrons when a light is shone on it.

Silicon is what is known as a semi-conductor, meaning that it shares some of the properties of metals and some of those of an electrical insulator, making it a key ingredient in solar cells. Let’s take a closer look at what happens when the sun shines onto a solar cell.

The instantaneous output power (U*I) of the solar cell module moves on this U-I curve. The output of the battery pack is affected by the external circuit. Maximum power tracking technology is to use power electronic devices with appropriate software to make the battery pack always output maximum power. If there is no maximum power tracking technology, the output power of the battery module cannot reach the optimal (large) value under any circumstances, thus reducing the utilization rate of the solar battery module.

Independent research and development of high-efficiency MPPT intelligent computing control box The company's core technical advantages, the control system and the use of TI28035 chip, make the utilization rate of solar energy to be 99%. Compared with ordinary solar panels, it can save 30%~50%, and improve the conversion efficiency of light energy to electric energy at a high speed.
