You are determined to equip yourself with solar panels, but considering what it could cost you to have they installed by professionals, you are thinking of doing it yourself? Be aware that the task is quite possible, especially since there are currently solar kits to assemble you. Nevertheless, like everything else, self-installation has its advantages and disadvantages.
The solar kit in self-consumption
A self-consumption solar kit is a photovoltaic device generally composed of one or more solar panels and cables. Unlike photovoltaic solar panels on rooftops, which in most cases require a lot of technology and therefore the intervention of certified professionals, solar kits can be installed by you. Indeed, they are connected to the network via a simple electrical outlet or via a connection on the electrical panel and generally do not require major work since they are installed on the ground.
Several companies already specialize in this type of kit. The particularity of the latter is that it can be configured according to the needs of each individual, in terms of sizing, choice of product brands and guarantees. It is often delivered with all the necessary equipment for its assembly, which is intuitive and very easy. In fact, you will distinguish three types of solar kit: the kit without structure, the kit with a ground or roof structure and the complete solar kit with an inverter, an AC/DC box and power optimizers.
The advantages of self-installation kits
Using a qualified workforce for the photovoltaic installation represents on average 30% of the assembly cost. Knowing that the costs related to this labour force are not taken into account in the subsidies and grants given by the State, it is clear that choosing to build your own solar installation is really economical.
Most of the solar kits to be installed by yourself are ready to use and pre-wired, i.e. they do not require the possession of specific tools to be assembled, even those with a structure. It is then quite possible for beginners to install in one day a kit of 6 panels on the roof for example. These solar kits are "Plug'n'Play" or "Plug'n'Produce" according to the brand name, since it is enough to plug them directly into an electrical outlet or on the electrical panel to have green electricity.
The other side of the coin
First, it should be noted that electricity produced by a solar panel or a solar kit assembled by yourself is not eligible for purchase by EDF. Indeed, the company never buys back electricity unless the installation is carried out by an approved professional, in this case, a certified QualiPV electrical module craftsman, or certified SP1 and SP2 or certified 5911-ENR Photovoltaic. By extension, since you cannot resell your surplus, you do not also benefit from the self-consumption premium.
Secondly, installing a solar kit yourself requires a minimum of DIY skills, especially for roof installations. Indeed, you will have to be careful to be able to preserve the waterproofing of your roof during assembly. In general, the kits are accompanied by manuals and their reseller's website provides enough information and explanation for you to complete the installation.
Finally, if a ten-year insurance policy is automatically issued for any installation carried out by a certified professional, you will not benefit from it by assembling your solar kit yourself.
