Solar panels have become increasingly common around the world to generate electricity. But, often, we wonder how do these panels work? Solar panels are a source of clean and renewable energy and they help in reducing our dependence on fossil fuels. In this article, we will explain how solar panels work.

Solar panels consist of photovoltaic (PV) cells, which are responsible for converting sunlight into electricity. These cells are made up of layers of silicon and other materials, which absorb the photons in sunlight. When these photons are absorbed, electrons are freed from their atoms, and the movement of these electrons generates an electric current. This current is then collected by wires in the panel and sent through an inverter, which converts the direct current (DC) into alternating current (AC) that can be used to power homes and businesses.

The efficiency of a solar panel is determined by the amount of sunlight it receives. The efficiency of solar panels range from 15% to 22%. Other factors like the type of PV cells used, panel size, and manufacturing process also affect the efficiency of a solar panel.

Solar panels can be installed on rooftops or on the ground, in areas where sunlight is ample. They require minimal maintenance and have a lifespan of 25 to 30 years. Though installing solar panels can be expensive, it offers long-term benefits, like significant savings on electricity bills.

Solar panels have a significant positive impact on the environment too. They do not emit greenhouse gases and are a sustainable source of electricity. Additionally, the generation of solar electricity does not deplete natural resources and does not produce any waste.

In conclusion, solar panels work by converting sunlight into electricity using photovoltaic cells. They are efficient, have a long lifespan and are environmentally friendly. With solar power generation becoming cheaper and more popular, it is likely that we will see more installation of panels in the future. By investing in solar power, we can reduce our dependence on fossil fuels and create a better future for ourselves and our planet.
