Hello. Is it possible to install software from tar gz files on Solus?

.tar.gz is just a gzip-compressed archive, so... Yes? Decompress it and follow its specific instructions (it's either pre-compiled software or source that needs to be compiled).

    aleksvor Thanks for your answer. I decompressed it and looked all the files and
    installed the required packages mentionned in the docs. But it's not explained how to install it. Do you have any idea of how I install it ? I'm pretty new on Solus so that's the first time I try to install a software without using the Software Center 😅

        There should be some readme/install text file in the tar explaining what to do.
        At worst, the website from where you downloaded it should provide installation instructions.
        What is it, by the way ?
