Photovoltaic solar electrification of households

There is a significant number of claims received by solar energy companies by individuals who want to electrify their homes. The main problem with such facilities is high cost installation in relation to the amount of energy that are capable of providing. This factor collides with the high level of technology and consumption that have existing homes. Make a solar photovoltaic installation to electrify a home can be interesting and profitable however you need to know the pros and cons of this type of facility.

Why electrify a house with photovoltaic solar energy?

Advantage

There are several attractions to electrify a house by means of photovoltaic solar panels:

– Electric range: It is perhaps the most attractive feature such facilities. Counting with a properly sized and installed solar photovoltaic installation is possible to dispense entirely supply network with possible breakdowns and increases rates

– On the other hand often it results electrification thus be the only possible in isolated areas where it is extremely difficult arrival of the electricity grid

– Long duration and strength of the solar photovoltaic installation-The lack of components with mechanical parts to wear out. This coupled with durable design of these makes them very difficult breakdowns. Normally the components undergo rigorous quality control to ensure reliability. And photovoltaic solar panels are designed and rigorously tested to withstand beyond the expected thermal conditions that may occur in normal use in any climate of the earth

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

– Cost effectiveness. Despite being normally expensive facilities, it is possible to achieve profitability and even income with them.

-On The one hand in many isolated areas, it is more profitable to a photovoltaic solar installation pay wirings from the nearest electrified area.

– On the other hand in many countries they have established laws by which utilities are required to buy the energy produced by renewable methods at a rate much higher than the price they sell themselves. The owner of the PV system injects its entire production to the grid with a high rate while it consumes energy at a lower rate. You manage to make profitable purchase installation and amortized over a period of time ranging from 5 to 15 years on average – this way a positive balance of sales ratio is obtained. From that point there will be an income and net profit.

ecological aspects

No less important and perhaps the most sought after features of this type of facility is its ability to produce clean, renewable energy and thus preventing the release into the atmosphere a lot of pollutants.

drawbacks

The main and perhaps only drawback of solar photovoltaic electrification of houses is the high cost of implementation. element which can make many applicants dismiss this option.

Types of solar photovoltaic electrification of households
Electrification systems home solar energy are two depending on with or without connection to the electricity grid:

Isolated systems:

Those without network connection. They are suitable for isolated areas where it is more expensive laying the power grid to make a photovoltaic system itself.

These types of facilities consist of the following components:

– Solar panels fotovoltaicos- components responsible for transforming light into electrical energy

– Battery- is the element responsible for storing electrical energy for times when it is necessary either because there is no sun or light enough power

– Regulator- is the device that prevents the battery suffers overload when has the full load and panels continue generating electricity.

– Inverter (optional) is the device that converts direct current electricity from the panels into alternating current. The vast majority of appliances running on AC power as it is the type of current flowing through the grid.

However, there are equipment for sale prepared to work with DC and 12 volt which could dispense with this component

Systems connected to network

PV systems are already electrified areas with the overall network. You can see two types of applications:

– Solar photovoltaic production aiming at auto-supply network support at times when missing energy or to dump the surplus energy

– Injection to the network of all production of the PV system as a normal consumption of the network is done. This option is certainly the most interesting economically when there are laws that take precedence production of electricity from renewable sources. In these cases you’ll want to sell as much as possible to the network at a high rate recovering it when we need energy, but at a much lower rate.

These types of facilities consist of the following components:

– Solar panels fotovoltaicos- components responsible for transforming light into electrical energy

– Investor: This is the device that converts direct current electricity from the panels into alternating current. In these types of facilities should be employed investors of the highest quality (sine investors) that convert the current from the panels into another identical to the network characteristics. This is usually specific converters for this application.

– Contador- element which represents the amount of electricity injected into the network (must be an independent meter that records consumption is done on the network)
