You can connect your solar panel either in series or parallel depending on what you want to achieve.
For instance, if you want more voltage, it is advise for connect your solar panel in series and if you wan to achieve more current, you should do parallel connect.
How do we achieve this?
series connection: for example if you want to connect 2 identical solar panels in series connection. to achieve this, you will need to connect the positive (+) of your first solar panel to the negative of your second solar panel (-). This way you will be left with the negative of the 1st panel and positive of the 2nd panel.
Parallel connection: to achieve this for 2 identical panel, you will need to connect the positive (+) of the 2 solar panels together and the negative (-) together. this way you will achieve more current and maintain the same voltage output. #HIVEDIY
