JUNCTION BOX FOR PHOTOVOLTAIC SOLAR PANEL

PROBLEM TO BE SOLVED: To provide a junction box for a photovoltaic solar panel which enables optimization of electrical connection between the junction box and the solar panel and can be automatically mounted in an assembly line.SOLUTION: A junction box for a photovoltaic solar panel comprises a housing 1, a lid 2, a first connector 3 and a second connector 4. The housing 1 comprises sidewalls and a top wall 13 defining an interior space. The first connector 3 comprises a first contact element 5 and the second connector 4 comprises a second contact element 6. Said contact elements penetrate at least one of the sidewalls, so that the contact elements provide an electrical contact from external contact elements to internal contact elements, such as solder tails. The internal contact elements are arranged at least partially in said interior space 10. The top wall 13 comprises an opening extending only partially in said top wall 13. Said opening is located in the top wall 13 such that access to said solder tails in a substantially perpendicular direction to the surface of a solar panel for connecting the solder tail to the solar panel is provided.
