To respond to your question directly, using "we" can signal solidarity. However, using "you" can do so as well depending on the style that you adopt.
I will also respond to other users' answers that are trying to discourage you from using first or second person.
Writing in first and second person can signal Classic Style, a style explained by Thomas and Turner (2017). The style adopts the following stances: truth can be known, language is a window to truth, the situation is someone talking to another person, and the motivation is to show truth, among other stances (Ibid.). With these stances, the style helps writers avoid the pitfalls of academese (Pinker 2015). Therefore, it is not surprising that the style has been used in academic texts throughout history (Thomas and Turner 2017).
It's important to note that using first and second person is not sufficient to successfully use Classic Style. The style is successfully used to the extent that writers adopt the same stances as the style. This also means that a text could avoid first and second person altogether and yet adopt many of the Classic Style stances.
As to concerns about objectivity (which other Stack Exchange users have), it's important to note what scientific paradigms you are using (Kuhn 2012 and Maxwell 2012).
For example, critical realism takes the stance that reality is a phenomenon external to human subjectivity, and yet it is always filtered by a human lens (Maxwell 2012). Some simply recognize that academia is an ongoing conversation in which "they" are talking and "I" join (Graff, Birkenstein, and Maxwell 2014), while others have a narrower stance, such as that academic publications are an attempt to change other academics' ideas about the world (McEnery). Yet others go further and claim that knowledge should always be situated in its all-too-human source because not doing so would be irresponsible (Haraway).
In all of these cases, there is a human community involved in the pursuit and the generation of knowledge. If you are engaging with such a community, I would argue that using the first person is clearer and more responsible.
Having assuaged that fears associated with the first person, using the second person becomes a trivial leap. It is simply part of adopting a style and a paradigm that recognize humanity in science.
