Solar Photovoltaic

Photovoltaic Solar Energy

The solar photovoltaic systems can convert solar energy into electrical energy anywhere in the world and independently. One application that has had the technology is the electrification of houses

Why electrify a house with solar photovoltaic?
Advantages
There are several attractions to electrify a house by means of photovoltaic solar panels:

Independent power: It is perhaps the most attractive feature in this type of facility. Counting on a photovoltaic solar installation is properly sized and installed can dispense altogether supply the network with their potential failures and their rate increases

Moreover in many cases this form of electrification becomes the only possible in isolated areas in which it becomes extremely difficult the coming of the electricity grid.

Long duration and strength of the installation: the solar photovoltaic components with no mechanical parts to wear out. This coupled with the rugged design makes these faults are very difficult. Normally the components undergo strict quality control to ensure reliability. So solar photovoltaic panels are designed and subjected to rigorous testing to withstand more than the expected thermal conditions which may affect its normal use in any climate of the earth.

– There are solar photovoltaic installations are maintained in good yield from the 70s of last century.

Profitability

Although it is usually expensive facilities, is possible and even profitable income with them.

On the one hand in many isolated areas, be more profitable to make a solar photovoltaic power lines that cover from the nearest electrified area. Moreover, in many countries have established laws by which power companies are obliged to purchase energy produced by renewable methods at a price well above the rate which they themselves market. The owners of the photovoltaic inject its entire production to the general network with a high rate as it consumes power at a low rate. In this way we obtain a positive balance of the relationship of sales – to achieve profitable purchase installation and amortized over a period of time between 5 and 15 years on average. From that point there are income and net profit.

Ecological aspects

No less important and perhaps the most desired features of such facilities is its ability to produce clean, renewable energy, thus preventing the release into the atmosphere a large amount of pollutants.

Disadvantages

The main and perhaps only drawback of solar photovoltaic electrification of houses lies in the high cost of implementation. These elements that can make many applicants discard this option.

Types of solar photovoltaic systems for electrification of households

Electrification systems solar houses are two in terms of whether or not connected to the electricity grid:

Isolated systems:

Those without a network connection: Are indicated for isolated areas where it is more expensive electricity network tended to make a photovoltaic system itself.

These types of facilities consist of the following components:
Solar photovoltaic panels: Component will transform light into electrical energy.

Battery: Is the element responsible for storing electrical energy for times when they are needed either because there is sunlight or not enough power

Control: Is the device that prevents the battery suffer overload when the load is complete and the panels are generating electricity.

Investor (optional): Is the device that converts DC electricity from the panels into alternating current. The vast majority of appliances and works on AC power that is the kind of current flowing through the mains.

However appliances are on sale for operating on DC and 12 volts with what this component could be dropped

Network-connected systems

PV systems are electrified areas and the overall network. You can see two types of uses:
-Solar photovoltaic production aiming at auto supply network support at times when energy is missing or to dump the surplus energy.

-Injecting a network of all production of the photovoltaic system while doing a normal consumption of the network. This option is undoubtedly the most economically interesting when there are laws favoring the production of electricity from renewable sources. In these cases interest to sell as much energy as possible to the network by retrieving a high price when we need it, but at a much lower rate.

These types of facilities consist of the following components:
Solar photovoltaic panels: Component will transform light into electrical energy.

Investor: This is a device that converts DC electricity from the panels into alternating current. In these types of facilities must be used investors of the highest quality (inverters sine) which convert electricity from the panels in another identical characteristics to the network. This is usually specific converters for this application.

Counter: Element which represents the amount of electricity injected into the

network (must be an independent accountant that records the use made of the network).

NEED FOR EFFICIENT USE ELEMENTS AND LOW CONSUMPTION

In theory it is technically possible to make a solar photovoltaic installation to meet any demand of energy for very high that is. However the fundamental limitation of these facilities it is the high cost of them.
Make a solar photovoltaic installation for a home is often an important demand of economic outlay. Our current society is accustomed to wasting energy. We live surrounded by several other components that require a constant flow of energy. Electrify a house conventional middle class of any country will require an initial outlay that will make it unacceptable for many people, though in future it can be amortized.

To carry out effective facilities at a price so exorbitant it becomes necessary to take efficiency measures and savings to achieve greater utilization of each kW produced. With the use of appropriate elements of consumption and the development of habits that prevent energy waste, you can achieve a very significant reduction of apprehension surface which results in a significant reduction in the cost of installation.

Among the most suitable for energy savings include:
Lighting: It is first important to maximize natural light from the sun during the day.

For times when it is not possible and you must use artificial lighting is recommended avoided at all incandescent bulbs, which, although a priori are the most economical are also the most wasteful of energy. Incandescent bulbs convert much of the energy they receive into useless heat.
For more adequate lighting are saving light bulbs, although in the store are more expensive than incandescent, due to much lower power they have (save up to 80%) and long duration are the most economical.
They are also fluorescent tubes suitable for spaces where there is a constant on and off for while consumption once lit is not very high at the time of latching when consuming a significant amount of energy.
As important as having the right components is the use made of them. It will avoid leaving lights on in rooms where no one and no light stays on in terms of activities that will develop in them.

Appliances: To reduce the power consumption of appliances shall be to acquire those that are low consumption which in principle are not more expensive than conventional ones. This type of appliances is becoming common to find in supermarkets and manufactured by the big brands

Special attention must be paid to the refrigerators which are large energy consumers. Must be kept clean the grill back and try to renew them every 10 years it is estimated that a refrigerator consumes more than 10 years twice as a new one. The proper and efficient use of electrical appliances is also a major factor. We shall always strive to maintain a perfect condition and used only when strictly necessary (washing machines and dishwashers with full charge)

The sparing use of elements would save 65% energy without changing any habit of consumption.
