Solar Panels High Output
The solar panel - The different technologies
The solar panel - The different technologies
There are three types of solar cells: monocrystalline polycrystalline thin films.
Mono and polycrystalline cells are made from wafers cut from blocks of silicon, which are then modified through a process known as "doping." This involves heating the cells in the presence of boron and phosphorus, which alters the structure of silicon So making a semiconductor. This method is the same as that used to manufacture computer chips.
Once the wafers were doped, then a heavy fine Power cable electrically conductive collection applied to each side of them.
thin-film technology uses a differenttechnique, and is in the deposition of layers of different materials directly on metal or glass. Thin film panels are the most common type of amorphous silicon, which is everywhere in the world watches and calculators right of the grid connected photovoltaic systems network wide.
flexible panels are Technology amorphous derivatives. They are made of metal or a substrate of thin plastic and can be rolled up or attached to curved surfaces. They are commonly used for camping and boating, but in general, are very expensive base dollarper watts, although designed for the largest gathering buildings are in competition with conventional rigid panels.
On the use of hardware, LCD panels use much more a semiconductor material panel output equivalent thin film. This is because a large amount of material lost in the cutting process the ball or silicon wafers tickets (wafers). The cut is made with a diamond saw, which could well have a sheet thicker than the wafer resulting if more half of silicon may be lost in this process.
Amorphous panels do not have this problem and you can use less than 1% on a panel crystal semiconductors. An example is the Kaneka thin-film modules. They have a thickness of active material only 0.3 microns.
Versus a typical thickness of the crystal cell 100 to 200 mm, it is only 1/600th of silicon, and does not take into account silicon lost by the cutting process for crystal cells.
Why is silicon used a theme?
There are two reasons. The first is the intrinsic energy energy Silicon is very necessary to highlypurified silicon used in solar panels.
The second is that the silicon of high quality suitable for this type of use is often limited due to demand the same in both solar cells and integrated circuits, which keeps the price than it should be.
The small amount of silicon used in solar panels to thin films which allows them to be more profitable, and one wonders why this is not the case now, despite the strong demand for solar panels in general are most likely has many to do with it!
Qualifications Panel
A number of different reviews on solar panels, we will So have a look at what they are and what they mean. Evaluation (peak) Power: This is the maximum sustained power of the group, assuming level Insulation (intensity of light falling on the panel) a kilowatt per square meter. In general, the classification of solar panel is peak power.
Nominal voltage (Vn): The voltage that the panel system is designed to be used in a panel of 12 volts is designed for a 12 volt system, but tensions are well above 12 volts. Some panels can be reconnected to accommodate six or 24 volts.
Other panels are designed for interactive systems on the network, and nominal output of 48 volts or more.
Peak voltage potential (Vp) is the voltage measured on the panel when the panel is the production of peak power.
current maximum energy (IM): The maximum available current from the panel of peak power.
Open circuit voltage (Voc): The maximum voltage available from the panel without charge. It is generally around 21 volts for a cell 36, 12-volt units. short circuit current (Isc): The current obtained when the panel output is short circuit with a level of solar radiation 1000 watts per square meter panel temperature of 25 ° C.
Temperature at rated power: This is the temperature that the types solar panels on the panel manufacturer. Most panels are scheduled for full power close to 25 ° C, which is a realistic figure that the temperature panel under typical Spanish can be up to 70 ° C. Figure 1 shows how temperature affects the energy production of cells crystal panels.
Current-voltage (IV) curves: These are graphs of output voltage against the current of different levels of sunlight and temperature. They can tell a lot about a panel's ability to cope with rising temperatures and cloudy weather performance. Examples of IV curves can be seen in Figure 1.
Obviously, the most important qualities to do the calculations for a power system are voltage and current at maximum power. A system rarely scores are calculated electrical control panel, since it is a function of both voltage and current. Some panels are rated at voltages slightly higher or lower than others, which affects amount of power available. The open circuit voltage and short circuit ratings of power are important in terms of security, particularly the tension par. A set of six panels in series, while having a nominal 72-volts, can generate over 120 volts DC, more than enough to be dangerous.

How can I reduce the production of amplifiers in a solar panel?
I built my first solar cell to power a block power which has a sealed battery 28 amps-hour AGM. The transformer can be charged with a solar panel (via a DC port), but says he can use a maximum of 2.5 amps. I was thinking of making solar panels is connected in series to add the necessary tension of 14.2 to charge the battery. I can only find solar cells of 3.5 amps (average) or higher. This means that the end result would be the construction group is a panel Solar volts@3.5 14.2 amps. This is a booster for many energy package says it is not more than 2.5 amps of charge current. Is it possible to get the amp without playing with stress? Maybe a charge controller or something? This is new territory for me and you would appreciate any help.
To 14.2 volts should be good for charging a battery of 12 volts. The draw of 2.5 amps from your power supply is less than the 3.5 amps that the group publishes. This works until the battery is fully charged. At what time should be disconnected. This is a charge controller would be desirable.
