Purpose:
installation of alternative energy solar houses, the goal is: Get
dare power of inexpensive solar panels.
The facility consists of a controller, and one or neighborhoods become solar panels solar cells composed of several
You are responsible for producing electricity.
Overview:
These facilities are installed in areas where there are large winds and snow that can be damaged and all panels must be covered or that places them in the sun, avoiding nearby objects will produce shadows or transfer on the arrival of solar rallos.
normally used in remote homes that do not arrive at the common electrical grid.
To install such facilities must take into account the place where it is located, there are tables to know how many days of autonomy
of each area, it is necessary to calculate the necessary batteries.
photovoltaic solar energy is the second most used at home after combustion generators.

Converter 1.3.1 Panels:
solar panel is defined as the union of several cells called photovoltaic. Depending on the installation that you want to join you must obtain cells for proper tension, each cell can produce a voltage usually half a volt. Solar panels have
sandwich are made of a glass layer, another vinyl acetate, the cells that want to put another layer of organic substrate and finally another set of layers of glass.
solar panels are the cells connected in series, the voltage varies with the number of cells that are made.

photovoltaic cell:
silicon itself has no electrons more or less, has four electrons in the last layer and you're done, then ... How do I get to have a positive and negative silicon? Then through doping. Doping is to introduce other polluting materials in smaller quantities or impurities in the parent material as in this case silicon. So if we introduce phosphorus into silicon have an electron get more each time, as phosphorus has five electrons in the silicon top layer and you get negative, otherwise, if we introduce aluminum under an electron or hole because aluminum has three electrons in the last layer. 1.3.2
Controller:
This system basically has three functions:
* Avoid overloading the battery that may cause damage
.
* Prevents battery discharge during periods of insufficient sunlight.
* Ensure the functioning of the system the point of maximum efficiency.
The regulator maintains a constant supply voltage and circuit and battery charging. There are two types
the parallel or shunt and series, the most used are the shunt, the series are for larger installations.
Accumulator:
The reservoirs can be used to accumulate and consume energy in times of low solar radiation or night, these teams of accumulation are the batteries.
The battery consists of two compounds usually (Lead Acid). They are built in modules called vessels, which have two electrodes, the positive and negative, each vessel can reach to 2 volts.
The amount of energy that can storing a battery depends on its ability to be measured in A / h.
Batteries are composed of a series of electrode plates of lead.
Converter:
are the most advanced of all quantum energy converters are the most promising way to electro-solar power. This process is also called internal process of issuing photo. Fundaro-tally is produced by photo emission has a lower threshold for photon absorption and the light changes from birth to be electricity without going through a stage of thermal energy. Besides there are other photovoltaic cells, but PV is the only one that has a high optical absorption and the electrical resistance low enough to be able to convert solar energy into useful energy saving mode. Because there is a wide choice of semiconductors with the appropriate range of spectral absorption, we can select an appropriate material to cover the solar spectrum. These semiconductors are made by attaching positive and negative parts of silicon, which currently pays the most. All today's solar cells have in common three features: 1. An optical absorber that converts photons into electron-hole pairs. 2. An internal electric field to separate these charges. 3. Contacts at the ends of the semiconductor for connection to an external load.
Part converters photon absorbing semiconductor is chosen so that it has a band gap similar to the solar spectrum. We could not catch a solar cell with a low energy band gap but it seems ideal to soak up most of the spectrum, but the emf of the cell is limited by the energy band gap, and if this energy is small electromotive does so. It is unlikely that a photon has twice the energy that the Fermi level so there will always only a single electron-hole pair per absorbed photon and the photon excess energy dissipates.

1.5 Plan and schemes
Wiring diagram all devices that make the installation: Solar Panels

There are different types of plates. Also according to the geographical area to install the board requires different angles. Where possible it is that the midday sun rays from reaching the photovoltaic panel at right angles, giving an angle of + 15 degrees to the cardinal point where the sun sets. In this way we take more atardeser rays.
solar panels, mostly deliver a load voltage of 17 VDC This, when connected to the load, stabilizes in 14 VDC also recall that the panels can be connected in series Tenson raising to 24 VDC power generated is regulated by a device, voltage regulator, which does not allow to overload the battery bank and keep them afloat. Then the stored energy can be connected to a load at 12 to 24 VDC or investors using raise and turn it into 220 VAC
PV is the promoter to get the energy in space:
