Photo-voltaic Solar system
The photo voltaic Solar system outside the network and one connected to the electricity grid. In addition to its main components and, key, its advantages and disadvantages.
Solar system connected to the network or outside the network: differences.
Systems outside the network:
- Every domestic solar system will require the corresponding installation of panels that, in turn,
- will have to be accompanied by more components. In the specific case of the systems outside the network,
- they will be the following:
Batteries for the storage of energy
- This is the key element of this modality (and the one that pushes up the costs of it) since
- without a good battery,
- the power supply would be compromised during the night or on cloudy days
- for putting a couple of examples.
- The energy captured by the panels goes to the batteries that, in turn
- will provide the necessary energy to the different household equipment.
- For the above to be possible
- it is necessary that the domestic solar system includes an investor.
- Its function is simply to transform the direct current coming from the solar panels into alternating current.
Battery charge control system
- This is another essential element, since it guarantees that the battery does not suffer overloads.
- This optimizes the management of the energy that accesses and leaves the equipment for domestic storage
- Thus, in this case it would be possible to take advantage of the energy captured from the sun only with the placement of the panels and the incorporation of an invert-er.
- In these alternatives, the network itself would work in a way comparable to batteries:
- when more energy was produced than necessary, the excess would be diverted to the network.
- The scheme would work in reverse at those times when there was a deficit of energy captured by the sun, as after sunset.
Confluence points: hybrid systems.
- As each of the previous systems has its pros and cons, there are also hybrid alternatives for photo-voltaic installations with connection to the network
- with the incorporation of domestic storage batteries. These are basically the following:
Hybrid system for food.
In it, the batteries form the central nucleus. Thus, the panels transfer energy to this equipment and, from there; it would pass to the investor. This would connect with the network and, also, with a secondary system for the supply of energy to the basic equipment of the house, independently and, therefore, safe in the event of any blackout.
Hybrid support system.
In this case, interactive investors are the piece on which the system pivots. The panels are connected to the invert-er, which converts the energy and injects it into the electricity grid. The invert-er would also be directly connected to the storage system and, usually, to the management of charge and discharge of the battery.
What option to choose?
It depends on many things, including the area in which you want to set up the installation, the budget with which you count or your energy needs, among many other factors.
The only case in which the recommendation is clear is when the solar system must be installed in an area where there is no connection to the network, for example in the case of an isolated house. Now, for this, the initial investment will be greater since a good pinch of the domestic systems are taken by the batteries for the storage of energy.
The ARVIUPS Solar energy storage market, it is expected that the costs of these equipment will go down to open up to many more people the possibility of being self-sufficient from the energy point of view.
