The benefits of fluorescent lightingWhen the fluorescent lamp normally emits light, only a lower current is allowed at both ends of the lamp, so the voltage added to the lamp is slightly lower than the power supply voltage, but the fluorescent lamp needs a higher voltage breakdown when it starts to work, so the ballast is added to the circuit, which can not only produce a higher voltage when starting, but also stabilize the current when the fluorescent lamp works.

Photovoltaic arrayPhotovoltaic array is a DC power generation unit composed of a number of photovoltaic modules or photovoltaic panels assembled together in a certain way mechanically and electrically and with a fixed support structure.
