Photovoltaic solar energy systems allow the transformation of solar energy into electrical energy anywhere in the world and independently. One of the applications that this technology has had is house electrification.
There are a number of important demands that solar energy companies receive from individuals who want to electrify their homes. The main problem with this type of facility is its high cost of installation in relation to the amount of energy they are able to provide. This factor clashes with the high level of technification and consumption in current households. To realize a solar photovoltaic installation to electrify a house can be interesting and profitable however it is necessary to know the pros and cons of this type of installation.
Why electrify a house with photovoltaic solar energy?
There are several attractions of electrifying a house with photovoltaic solar panels:
Electrical autonomy: This is perhaps the most attractive feature in this type of installation. Having a properly dimensioned and installed solar photovoltaic installation, it is possible to completely dispense with the supply of the grid with its possible breakdowns and tariff increases.
On the other hand, on many occasions this form of electrification is the only possible in isolated areas where it is extremely difficult to reach the general electricity grid.
Long service life and resistance of the installation – Solar photovoltaic systems lack components with mechanical elements that can wear out. This, coupled with the rugged design of the same makes it very difficult to breakdowns. Normally the components undergo rigorous quality controls to ensure their reliability. Thus, photovoltaic solar panels are designed and subjected to rigorous tests to withstand beyond the thermal conditions that they are expected to suffer in their normal use in any climate of the earth.
There are solar photovoltaic installations that have been maintained with good performance since the 70’s of the last century.
Profitability. Despite being normally expensive installations, it is possible to achieve profitability and even income with them.
On the one hand, in many isolated areas, it will be more profitable to carry out a photovoltaic solar installation than to pay for the electricity supply from the nearest electrified zone.
On the other hand, in many countries laws have been established by which electricity companies are obliged to purchase energy produced by renewable methods at a much higher price than the tariff that they themselves sell. The owner of the photovoltaic installation injects all its production into the general grid at a high rate while consuming energy from it at a low rate. In this way, a positive balance of the sale/purchase ratio is obtained, which makes the installation profitable and amortizes it over an average period of 5 to 15 years. From that moment on there will be a net income and net profit.
No less important and perhaps the most sought-after feature of this type of facility is its ability to produce clean, renewable energy and thus prevent a large amount of pollutants from being released into the atmosphere.
Disadvantages of Photovoltaic homes
The main and perhaps only drawback of solar photovoltaic electrification of houses lies in the high cost of its execution. This element may cause many applicants to discard this option.
Types of photovoltaic solar home electrification systems
The systems of electrification of houses by solar energy are two depending on whether or not they have connection to the general electrical network:
Those without a network connection. They are suitable for isolated areas in which it is more expensive to install the electricity network than a photovoltaic installation in itself.
These types of installations consist of the following components:
Solar photovoltaic panels – Components in charge of transforming light into electrical energy
Battery – It is the element in charge of storing electrical energy for the moments when it is necessary, either because there is no sunlight or not enough power.
Regulator- The device that prevents the battery from overcharging when fully charged and the panels continue to generate electricity.
Inverter (optional): is the device that transforms direct current electricity from the panels into alternating current. The vast majority of household appliances operate on alternating current, since it is the type of current that flows through the general network.
However, there are devices available for sale that are ready to operate with direct current and 12 volts.
