Panel Solar

Introduction

A solar panel (also solar module, photovoltaic module or photovoltaic panel) is a packaged, connected assembly of photovoltaic cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each panel is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a panel determines the area of a panel given the same rated output - an 8% efficient 230 watt panel will have twice the area of a 16% efficient 230 watt panel. Because a single solar panel can produce only a limited amount of power, most installations contain multiple panels. A photovoltaic system typically includes an array of solar panels, an inverter, and sometimes a battery and or solar tracker and interconnection wiring.

Description

The solar panels are formed by a great quantity of photovoltaic cells connected in series parallel to increase the tension and the current that they can deliver, encased with polymers resistant to the radiation ultraviolet and mountings after a surface of special glass that offers protection against the environmental pollution and against the sudden changes of the climate (frosts, rains, hail, etc.). Generally, the later face of the modules is constructed by a material of recognized resistance to the climatic conditions adverse, as for example anodized aluminum, and is sealed by silicone to work adequately in the open air.
