Using 2 different brand panel.

System

I have 2 panels, one is Sharp the other is Sanyo.

Both have dfferent volt and amp, can I use them together., Is this safe?

Thank you.

Re: Using 2 different brand panel.

It depends...

If the Vmp of the two panels are close (16 vs 18 volts)--you can probably add them in parallel without much problem.

If the Imp is close (within 10% or so), you can add them in series together without much problem...

But, in the end, it depends. How many of which brand/model of panels, and what type of charge controller / load do you have (for Charge Controllers, is a PWM or MPPT type, etc.). If you add many panels in parallel (typically 3 or more), then you should have a series fuse inline with each panel to prevent against a panel getting an internal short circuit and melting/catching fire.

You only have two panels--so, in your case, series fuses inline with each panel is probably not needed at at all (unless one panel is very large, and the other is very small).

Nothing can be paralleled with the Sanyos, they are a very odd ball voltage and require an Mppt controller.

use different controllers for each pv.
