Since the electricity produced by the PV array is direct current, an inverter is used to convert it to alternating current so that we can utilize it easily. Inverter units installed with different protection devices ensure the safety of the system and automatically switch the load and available power. These are used to store solar energy.
This article overviews the main principles of storage of solar energy for its subsequent long-term consumption. The methods are separated into two groups: the thermal and photonic methods of energy conversion. The compari- cal and electrochemical reactions is given. arly along with the growt h of gross domestic produc t (GDP). about 2.0%.
Inverter units installed with different protection devices ensure the safety of the system and automatically switch the load and available power. These are used to store solar energy. They are the most important components of a solar photovoltaic system. The success of a solar photovoltaic system largely depends on the battery storage system.
The working principle of solar panels is to use the photoelectric effect, also known as the photovoltaic effect. Photovoltaic effect refers to the phenomenon that an object generates electromotive force due to the absorption of photons. The photovoltaic effect occurs when sunlight or other light strikes the PN junction of a semiconductor.
The semiconductor device that transforms solar light in electrical energy is termed as ‘Photovoltaic cell’, and the phenomenon is named as ‘Photovoltaic effect’. To size a solar PV array, cells are assembled in form of series-parallel configuration for requisite energy , , .
Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been underway since very beginning for the development of an affordable, in-exhaustive and clean solar energy technology for longer term benefits.
