I recently wrote my first paper and submitted it to the solar energy journal in late August. About two weeks later, its status changed to “under review” and an email has sent to me with a link to a page where I could track the progress of my submission. The page shows “2+” reviewers were invited to review my manuscript, and “2+” reviewers have accepted the invitation. In mid-October, “2” reviewers completed their review. Since then, neither the manuscript status nor the number of reviewers who completed their review has changed. It’s still “under review” with “2” completed reviews, and the date of the “Last review activity” is still the same as before (mid-October).
The journal says the average review speed takes up to 8.4 weeks, making me feel worried and also confused about whether I should send an email to the editor or wait longer.
Many Thanks.
