Components Of A Solar Photovoltaic System

Here s your chance to discover what goes into both grid direct and battery based pv system designs.

Components of a solar photovoltaic system.

A photovoltaic pv system is a power system designed to supply usable solar power by means of photovoltaics consisting of several components such as dc ac power inverter battery bank system and battery controller and auxiliary energy sources. A charge regulator or controller for a stand alone system. A solar energy system produces direct current dc. Pv modules groups of pv cells which are commonly called pv panels.

Solar pv systems occasionally produce energy at times when it isn t needed for example if a home is empty. Mounting your pv panels is of critical importance. The basic components of a home solar power system. Pv modules which together form a pv array with racking a grid direct inverter listed to ul1741.

They are typically made of silicon crystal slices called cells glass a polymer backing and aluminum framing. It comprises the solar array and the balance of system components. Pv panels which cost anywhere from 2 40 per watt to over 5 per watt are the single biggest expense of a pv system. The type of component in the system depends on the type of system and the purpose.

Ground mounted systems tracking vs. 1 roof attachments 2 mounting rails and 3 module clamps. For example a simple pv direct system is composed of a solar module or array two or more modules wired together and the load energy using device it powers. Centralized systems rooftop vs.

Utility systems distributed vs. Overview of the main components photovoltaic array. Solar panels can vary in type size shape and color. In most cases the size of a pv module refers to the panel s rated output wattage or electricity generating potential.

Their placement and. Fixed tilt systems and new constructed vs. In addition to pv mod ules the components needed to complete a pv system may include a battery charge controller batteries an inverter or power control unit for alternating current loads safety disconnects and fuses a grounding circuit and wiring. An inverter for a utility grid connected system and when alternating current ac rather than direct current dc is.

Pv systems can be categorized by various aspects such as grid connected vs. Stand alone systems building integrated vs. Following are the major components of a grid direct system. Each of these components can vary in size weight and material so manufacturers typically provide detailed information to aid in component selection and system design.

The most common loads are submersible water pumps and ventilation fans. Solar mounting systems are composed of three parts. Rack mounted systems residential vs.
