Isolated photovoltaic installations can be defined as a current generation system without connection to the electrical network, that is, there is no link with the common network, thus providing us with energy solely and exclusively from the sun. In our article today we will delve into this interesting photovoltaic system that continues to make a strong impression on the market.
What are isolated photovoltaic installations?
Isolated photovoltaic systems are ideal for locations that do not have access to the common electrical network. Although if there were, an isolated photovoltaic installation will always be less expensive and more efficient, since laying an electrical network is quite expensive and, in addition, the payment of the bill for consumption continues to increase.
Isolated installations are used more and more for all kinds of uses. For example, from the simple lighting of field sheds, warehouses, etc., to supplying all types of consumption in homes and buildings, pumping and water treatment, signaling and communications, agricultural and livestock activities, all types of industry and even Street lighting.
The community has understood that it is a new energy model that is advancing by leaps and bounds, and that it allows us to have enough energy in an ecological and completely usable way, starting from a natural element such as the sun. Without a doubt, it is fascinating that as human beings we have reached this point of understanding of what this type of alternative energy means today in our lives, especially photovoltaics. In addition, the increasing use of this type of installation and the incorporation of more and more technology has caused prices to drop to the point that they are currently the most profitable option in many cases.
Elements that make up isolated photovoltaic installations
Basically, an isolated photovoltaic installation is made up of elements such as photovoltaic solar panels , a charge regulator and a solar battery. In the case of the battery, this is an element whose task is to store the energy provided by the solar panels. Therefore, it is the one that will provide us with energy during the hours that there is no sun.
On the other hand, the charge regulator also plays an important role in any photovoltaic system. This is in charge of controlling the charges in the battery, regulating the overloads or discharges that could affect the accumulator, so one depends on the other. These types of configurations generate electricity in direct current, like the one we can use in a vehicle through the cigarette lighter socket.
Now, the most common configuration in homes is the one made up of photovoltaic solar panels, a charge regulator, batteries and an inverter. This last element fulfills the role of converting the energy stored in the batteries into perfectly consumable alternating current. This alternating current is the same as the one supplied by the electricity company and therefore it is the one we use for any appliance or other normal equipment in a home.
Of course, there are other types of configurations such as solar pumping. This is made up of 3 elements: solar panels, inverter or solar variator and the pump. In this case, an accumulator is not required, but this limits the possibility of pumping water only during sunny hours.
Thus, we can find several configurations in isolated photovoltaic installations, they are options that give us the opportunity to choose the one that best suits our needs and budget, for the benefit of a better use of energy that will result in savings for our economy.
