Solar Renewable Energy Malaysia 太阳能绿色能源 Solar Power: Introduction

A. How Solar Works :

Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current This entire process is known as the Photovoltaic Effect.

An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricity to supply all of its power needs. Assisted by an inverter, a device that converts the direct current (or DC current), generated by a solar panel into alternating current (or AC current), solar panel arrays can be sized to meet the most demanding electrical load requirements. The AC current can be used to power loads in your home or commercial building, your recreational vehicle or your boat (RV/Marine Solar Panels), your remote cabin or home, and remote traffic controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more.

B. Solar Components :

A solar photovoltaic power generation system is composed of a solar photovoltaic panel, a solar energy charge controller and a storage battery (pack). And an inverter should be equipped if a 220V output power supply is needed. The function of each component is illustrated below:
