Photovoltaic | Viessmann

Viessmann are Photovoltaics (PV) converts light into electricity using semiconducting materials that reflect the effect of photovoltaic photochemistry, and electrochemistry. The photovoltaic effect is used to commercially generate electricity and photosensors.

A photovoltaic system uses solar modules, each comprising a number of solar cells, which generate electricity. PV insulation can be installed on the floor, on the roof, on the wall or in the float. The mountain can be adjusted or used a solar tracker to track the sun in the sky.

Solar PV has certain advantages as a power source: once installed, its performance does not produce pollution and there is no greenhouse gas emissions, it shows simple simplicity in terms of energy requirements and silicon has high availability in the Earth crust, although other elements are required in the PV system. Silver-like production will eventually hinder further technological growth. Other disadvantages such as constant power generation and the need for power companies to compensate for more solar energy in combination to provide more reliability. General power supply to control peaks of need and possible uncertainties. Production and installation causes pollution and emissions of greenhouse gases and there are no effective recycling systems when they are at the end of their life span of 10 to 30 years.

Each PV cell is usually small, usually producing about 1 or 2 watts of energy. These cells are made up of different semiconductor materials and are usually less than the thickness of four human hairs.In order to withstand the outside for many years, the cells are bonded between protective elements with a combination of glass and / or plastics.

Modules can be used individually, or a few can be linked to create arrays. One or more identical members are then connected to the electrical grid as part of the complete PV system.

PV modules and arrays are one part of the PV system. Systems include solar panels that point to solar panels, as well as components that take up current modules generated by the modules and convert them into alternating current (AC) power that is used to power all electrical appliances in your home.

The largest PV systems in the country are located in California and generate energy for resources to be distributed to their customers.

 Soon solar cells were being used to power the satellites in space and with little things like counters and clocks. Today, electricity from solar cells has become increasingly competitive in many regions and photovoltaic systems are used in large scale to help grid power.

Silicon Solar Cells

These cells are usually assembled into large modules that can be placed on the roofs of residential or commercial buildings or used on floor racks to create large, scale-assisted systems.

Thin-Film Solar Cells

One of the most widely used photovoltaic technologies is known as small film solar cells because they are made of very thin layers of semiconductor material, such as cadmium telluride. Copper indium gallium diselenide. The thickness of these layers is only a few micrometers — that is, half a million feet.

Photovoltaics is the direct conversion of light into electrical energy using semiconducting materials such as silicon. The effect of photovoltaic is an important subject learned in physics and chemistry.
