solar panels make voltage but no current Assuming that the modules are not defective and that they are exposed to sunlight, then there is a very simple answer: There is no conductive connection between the modules. If there were a connection, current would inevitably flow. . What a waste of time I had taking down 11 solar panels only to discover something else was wrong. Here are the causes one by one – This is the most suspected cause of this. . Low solar panel voltage may be due to different factors, requiring diagnosis and repair for better performance. Maximum Power Voltage (Vmp) is the maximum voltage when there is a current.
