mixing solar panels

[hayeshouse]

I bought a Zamp solar kit off of the marketplace. It came with a 170w panel, but I'd like to add two more panels. Is it ok if the two extra panels are 175w each? Also, it didn't come with an inverter. Once I add two more panels, what size inverter should I buy?

It depends on the specs , on the label at the back

Voc
Vmp
ISC (amps)

If they are all close together it won't be an issue. If they are wildly different you will get losses , calculators are available online to figure it out exactly

What are you hoping to power ?

What kit? You cannot just connect a bunch of panels willy nilly to an SCC.

I swear this is another post I responded to a few days ago.

In general as long as the panel volts are same and amps and watts are close you can connect them together.

Check the specs on the label.

Your 175 watt won't put out as much because the 170 will pull it down but not enough to make a big difference.
