Photovoltaic industry chain

Design and Installation of Solar PV SystemsModern society relies on energy for daily needs like industry, heating, transport, and agriculture, mostly met by non-renewable sources (coal, oil, gas). However, these cause environmental harm, are unevenly distributed, and face price volatility due to limited reserves—driving demand for renewable energy.Solar energy, abundant and capable of meeting global needs, stands out. Standalone PV systems (Fig 1) offer energy independence from utilities.

DefinitionA photovoltaic (PV) cell is a semiconductor device that converts light into electrical energy. The voltage induced by the PV cell depends on the intensity of the incident light. The term "photovoltaic" originates from its capability to generate voltage ("voltaic") through light ("photo").In semiconductor materials, electrons are bound by covalent bonds. Electromagnetic radiation consists of tiny energy particles called photons. When photons strike the semiconductor material, electrons
