Why do solar panels need inverters? Solar cells need inverters because their DC output needs to be converted into AC power. The main reason for this is that most of our household appliances need AC power to work properly. Therefore, the inverter completes the conversion. It receives DC power from solar cells. Then, the inverter uses various electrical and electronic components to oscillate the DC input at a frequency of 50 or 60 Hz. The output of the inverter is a sine wave current, called alternating current. When the DC power of the solar cell is converted to AC power, our household equipment can use it to operate normally. What is a solar cell? Solar cell is a prismatic or rectangular device that can convert light energy from the sun into electrical energy. This energy generation process will occur through the photovoltaic effect. Solar cells are the simplest form of pn junction diodes, whose electrical characteristics change with exposure to the sun. Solar cells are photovoltaic or photovoltaic cells, which operate with photovoltaic effect to generate direct current. When these cells are combined, they form a solar module. A single solar cell can only produce a small amount of current. A single solar cell can only produce an open-circuit voltage of about 0.5 V DC. Therefore, when you combine multiple solar cells in one direction and plane, you create a module. They can also be called solar panels. When a single solar cell is combined into a panel, we can use a lot of solar energy.
