Solar and Wind Energy

Solar panels and wind turbine There are two main types of solar panels for 1) electrical systems and solar panels 2) solar water heating panels. We will discuss later, for heating water. At this time, we speak of photovoltaic (PV) panels to provide electricity. Photovoltaic systems convert sunlight directly into electricity. “Photo” refers to light and “voltaic” to electricity. A photovoltaic cell consists of a semiconductor material, typically crystalline silicon, which absorbs sunlight. You have seen solar cells at work in the simple mechanisms such as watches and calculators. You’ve probably seen the signs on the road. More complex solar cell produces electricity for homes and solar grid. The grid is a source of energy available to your local power company.

Photovoltaic cells are generally grouped into modules or panels, which contain about 40 cells. About ten modules are a photovoltaic generator, or group of panels.

Information on how PV panels work

Most solar panels contain a protective top layer, two layers of silicon circuits with a collection set special treatment of the upper layer and layer of a polymer support.

The top layer of silicon is treated to make it electrically negative, the back layer is treated to electrically positive. When the sun beats electrons of silicon, the electrons move to the bottom layer of silicon and the crowd of electrons in the upper layer. The electrons released from the upper layer is collected by electrical contacts on the surface of the upper layer and passed through an external circuit, providing power to the electrical system fixed to the panels.

New technologies will see in a later chapter, the different uses less expensive materials than silicon in solar panels to capture sunlight more affordable. Most photovoltaic solar panels to go in parallel with the south-facing slope of the roof of the roof of the northern hemisphere, the sun roof and the north of the southern hemisphere. Some of the panels can be mounted on poles or in the countryside, but such an investment would be prohibited by local legislation or an apartment, “the rules of the association. An important aspect is how many high-sun hours, the system receives. There will be solar panels to move in the shade of a non-Sun 9-15 (ideal)? Climate is stormy, foggy, dusty power? System vary depending on geographic location. People in the U. S. Northeast, for example, we need More solar panels on the roof to provide the same amount of solar power as anyone in Arizona.

Since solar energy systems to produce electricity only when the sun is shining, many consumers also be combined with the solar array power supply, which provides additional power when solar panels do not produce enough. This type of solar system called the grid-tied system.
