What is photovoltaics?5 answersPhotovoltaics (PV) is the process of converting sunlight directly into electricity using solar cells. PV systems absorb sunlight and continuously convert it into electrical energy without any pollution or noise. They are reliable, safe, and cost-effective, making them suitable for applications in remote areas. PV materials are abundant, and the Earth receives a vast amount of sunlight energy, making it an inexhaustible and renewable energy source. Building a PV infrastructure can reduce dependence on international energy politics and volatile fossil fuel markets. PV technology has a long history, with the first observation of the photovoltaic effect dating back to 1839. Over the years, advancements have been made in solar cell manufacturing, integration, and research, leading to the development of efficient and sustainable photovoltaic systems.
How does photovoltaic work?5 answersPhotovoltaic cells convert sunlight directly into electricity by utilizing the photovoltaic effect. When sunlight enters a photovoltaic cell, the photons release electrons that can flow through an electrical load connected to the cell's terminals. Solar panels, which consist of photovoltaic cells made of semiconductor materials like silicon, convert sunlight into direct current (DC) electricity. The output power of a photovoltaic assembly can be utilized in different modes, such as grid-connection and isolated island operation modes, by controlling the grid-connection industrial frequency circuit and the off-network variable-frequency circuit. In a photovoltaic system, the electric power supplied to a DC motor by the photovoltaic modules is measured and adjusted to achieve the peak power based on the ambient temperature and incident solar radiation intensity. Overall, photovoltaic technology offers a reliable and environmentally friendly way to generate electricity from sunlight, with applications ranging from small-scale urban use to large-scale power stations.
