PV & Energy storage

Photovoltaics (PV) is a technology that harnesses sunlight to generate electricity through the photovoltaic effect. The primary components of a PV system include solar panels (modules), inverters, and mounting structures. Solar panels, typically composed of crystalline silicon solar cells, convert sunlight into direct current (DC). Inverters then transform this DC into alternating current (AC), making it suitable for use in homes, businesses, or the electrical grid. The mounting structure supports and positions the solar panels to optimize sunlight exposure.

PV systems come in various types, with grid-tied systems being connected to the utility grid and able to feed excess electricity back into it. On the other hand, off-grid systems operate independently of the grid, relying on energy storage solutions during periods of low sunlight. The advantages of PV include its status as a renewable energy source, low environmental impact with minimal greenhouse gas emissions, and the potential for reduced electricity bills by generating power on-site.

However, PV systems face challenges related to intermittency, as energy production is contingent on sunlight availability, varying with weather conditions and time of day. This challenge is addressed through the integration of energy storage systems.

Energy storage plays a pivotal role in capturing and storing energy for later use, contributing to the efficient integration of intermittent renewable energy sources and providing backup power during peak demand.
