solar panel

The Solar manufacturer in Australia is a process that consists of several stages. We are going to explain how a solar panel system is installed in your home and what needs to be done, from the project to commissioning and registration.

Stages prior to the installation of solar panel:

The first step in the process of installing solar panels is to obtain a photovoltaic installation proposal based on the possibilities of the home and an analysis of the current consumption generated by the home.

The second stage consists of having a team of professionals who know how solar panels are install carry out a preliminary study of the type, orientation, and surface of your roof, as well as the possible associate shadows to determine if all the requirements for the installation are met. Installation of solar panels selects the installation that best suits it and your consumption habits. This will help to obtain better performance from the photovoltaic installation.

Once this is done, a series of procedures and licenses must submit to the corresponding town hall for which. In most cases, we must wait for their approval. In addition, the corresponding fees and/or taxes that apply in each case must paid. It should be consider that you can count on bonuses for self-consumption facilities.

By having all the previous steps cover, you can now carry out the photovoltaic installation on your roof.

How is the installation of solar panel carried out?

We explain the methodology, step by step on how Solar Panel in Australia are assembled. However, we must consider that it is a meticulous process and that it must done with the greatest care by the responsible technician to guarantee the optimal functioning of the system and avoid future problems.

First step: Mount the supports of the photovoltaic installation

Before placing the solar panels on the roof, it is necessary to place the supports for them on the roof. Depending on its typology and inclination, the type of structure to use will vary. For example, the support structure will notthe same on a roof whose modules are place coplanar to it. Than on a flat roof in which the modules have to tilte in a certain way to obtain the greatest possible efficiency from the system. In addition, ballast the structure to avoid the so-called “sail effect” (that is, make sure that the panels and structure do not “fly away” due to the effect of the wind).

Second step: Fixing the cover and solar panel

Once the structure is located, we must fix it to the roof and place the photovoltaic panels on it. Depending on its type and inclination, this process is carry out in different ways.

The most usual thing is that the roof is incline (in Spain most roofs are inclined between 20º and 35º. Which favors the performance of our installation) and of Arabic type tile. However a different case may occur, such as tiles slate or flat roofs covered with asphalt cloth, among others. The anchoring of the support structure will vary depending on the roof on which it will anchore.

Once the structure is anchored on the roof, the modules are place and fix to it. After which they are interconnect with each other, to finally connect to the inverter.

Third step: The connection to the electrical inverter

The interconnection of the panels is carried out in series between the modules of the same row or string. And in parallel to connect the rows together depending on the panel/inverter configuration. This is done using so-called MC4 connectors to connect the modules in parallel, or directly to the inverter. It is important to tighten the connectors strongly, since a bad connection will have a negative impact. On the overall performance of the installation. Causing possible problems such as the so-called hot spots. Which can also affect the structure of the panel itself.

In this way, the total electrical generation of the module system is conduct to the same point, whose destination is to reach the inverter.

Finally, a parallel connection is made, Which can be made directly in the inverter. Thus completing the direct current (DC) part of the installation. And thus conducting all the energy collected by each panel through solar radiation in form of electrical current to the inverter. Which will be located at a point near the electrical panel of the house.

Finally, the inverter is connect to the electrical panel. As if it were a separate circuit in the home, thus completing the alternating current (AC) installation part.

Fourth step: Connecting the batteries

If you are going to choose to store the Solar energy in Australia that you generate, apart from how to install solar panels in your home, you are also interested in how to connect the batteries.

First you must have a hybrid inverter, capable of managing the charging and discharging of the batteries, since they are the most expensive and delicate element of the system. The storage capacity of your batteries will be based on your demand and the installed photovoltaic field.

There is more than one way to do it, depending on the voltage and capacity needed. The connection of the batteries can be done in parallel, in series or in series and in parallel, always with the same batteries. In the case of parallel connections, the capacity of the batteries is doubled, but maintains the same voltage. In the case of the series connection, the results obtained will be the opposite: the capacity of the batteries is maintained, but the voltage is doubled. And finally, if you opt for a series and parallel connection, both the capacity and the voltage will double.

Conclusion

Connect the batteries. Now that we have told you how solar panels are installed, you know that the installation of photovoltaic panels is laborious and complicated work for anyone unfamiliar with electrical knowledge, so it is always recommended to leave it in the hands of professionals in the sector with experience in this type. of montages.
