What does a solar cell produce, AC or DC?

A solar cell produces direct current (DC) electricity.

A solar cell is a device that converts the energy from the sun into electrical energy. It is made of semiconductor materials, such as silicon, which absorb photons from sunlight and convert them into electrons, creating a flow of electricity. Because the natural output of a solar cell is direct current (DC) electricity, it typically needs to be converted into alternating current (AC) electricity using an inverter before it can be used to power household appliances or fed into the electrical grid. However, some direct current equipments such as DC motors or LED lights could be powered directly by the solar cells. Additionally some systems can be set up to convert the DC to AC power on site for the purpose of consumption or distribution.

Solar cells are often grouped together to form solar panels, which can then be used to power a wide range of applications, from small-scale residential systems to large-scale commercial and industrial systems. The efficiency of a solar cell refers to how much of the energy from the sun it is able to convert into electrical energy. Today's typical solar cell has an efficiency of around 15-20%, meaning that it converts about 15-20% of the energy it absorbs from the sun into electricity.

Solar panels are typically composed of many solar cells connected in series and/or parallel to form a larger electrical output. The number of solar cells used in a panel and how they are connected will determine the panel's voltage and current output.

Solar power is an example of renewable energy. This is because the sun's energy is constantly replenished and will not run out like fossil fuels will. One of the main advantages of solar power is that it does not produce any emissions, making it a clean and sustainable source of energy. It also can be used in remote location where grid power is not available.

In addition, the cost of solar technology has decreased dramatically in recent years, making it more accessible and cost-competitive with traditional forms of energy. This has led to a significant increase in the adoption of solar power around the world.
