liviusAre you already convinced of the advantages offered by solar panels? The face of TV Sieg Dendoncker (33) certainly does. On Instagram, he stands proudly with the installation of solar panels he placed on the roof of his house with his own hands. After all, anyone who chooses to install solar panels themselves can save up to thirty percent on their installation. But is it wise to install the panels yourself? Construction site Livios It explains what you should pay attention to.

If you are planning to install solar panels on your entire rooftop yourself, then of course you should first check if the effort is worth it. The main reason to do this, of course, is to save on installation costs. You only pay for your materials. However, there are still some extras you should take into consideration.
What do you need to take into consideration?
In the first place, you have no guarantee that the installation was done correctly. Therefore, you are fully responsible for possible errors. In addition, you – and therefore not the installer – are responsible for any repair costs. You can reduce the risk of errors by bringing the installer to check afterwards. Although not every installer is willing to do this, the industry is very busy. Installers tend to help their customers first before supporting non-customers with after service.
You should think carefully about your custom-made installation plan beforehand, which is something that an installer usually takes care of. A good installation plan ensures maximum return with optimal routing and tilt. After installation, the installer also takes care of registration with the network operator, as well as ordering a mandatory electrical check. You will also have to take that into account.
Finally, you lose your entitlement to several financial benefits that allow you to reduce installation costs. In order to be eligible for a Flemish government allowance, installation by a REScert-certified installer is required.
How much do you save?
If in the end you choose to do everything yourself, then you only pay for the necessary materials. These costs consist of the panels themselves, the supporting structure, the reflector, and the cables. The total installation price will naturally depend on your personal installation: How many panels have you decided to install? What peak power do you need? What is the slope of your roof? For all of these, it doesn’t hurt to get information from a professional or installer. Watch here how you can calculate the cost of installing your own solar panels.
How will you go forward?
Prepare
With any installation, an initial inspection of your roof is key. You have to check if your roof can support the installation, this varies from roof to roof. The condition of your roof should also be good.
As mentioned earlier, it is important to prepare an extension plan in advance that takes into account your annual energy consumption, roof orientation and roof slope. Only this way you know how to position the solar panels for maximum productivity and how many solar panels you need at peak power.
release
Only after a preliminary examination and drawing up an extension plan, you can proceed to the actual assembly. Start with the supporting structure. Make sure you use the correct direction and incline. You attach the solar panels to the supporting structure. Be very careful when installing so as not to damage the solar cells.
cables
Next come the cables. You extend it completely from your rooftop to the reflector in your home. This is usually done through a ceiling duct or through holes drilled in an exterior wall. DC cables (DC cables) are used for this. To connect your inverter to your electrical box, you need alternating current (AC) cables.
The last step is to place the inverter. It is better to hang it in a well-ventilated room where there is not a lot of dust, so that the device can quickly lose its heat. You must first connect the AC cable from the inverter to the electrical box and then the DC cables from your panels to the inverter.

Three other points of interest
Finally, there are some important points – and potential pitfalls – to watch out for before installing:
• Installing the supporting structure is vital. It should not separate in windy and windy weather. So check it out carefully! Anyone with a flat roof should provide adequate ballast. This way your panels don’t explode and reduce stress on your roof.
• You cannot choose any reflector only. The choice depends on how your solar panels will be installed: parallel or series. In a parallel circuit, all plates are individually connected to an inverter. In a serial connection, all panels are connected in series and connected to a central inverter.
• Finally, carefully check any warranty terms, as you are fully responsible for possible errors. After installation, you must apply for a mandatory electrical check yourself and the installation must be officially registered with the network operator. Only then is your installation in complete order.
