I have 3 x 130W
panels on my
boat and want to add another panel. The new panel wil be about the same size and nominally 12 V same as existing
panels but will be a different brand.
I've got a pulse width modulated
regulator on the existing panels and it has enough capacity for the extra panel.
Is it ok to just connect the new panel in parallel with the existing panels and run the lot through my existing
regulator or, because this is a different panel, do I need to regulate it separately?
