I have a solar panels, with 5v with a 200ma output, I have it so this goes to a charge module which allows 3.7v lithium batteries to charge without exploding on me. If i hook another solar panel, same as the last one, into my build, will this put too much voltage into the charger module and blow my unit?
If you connect plain solar panels in parallell, you only need to worry about the maximum current your battery/ies can safley take. Your regulator seems to be able to take 1 A of current, so theoretically you can use about three of them in paralell. It does not say weither your solar panels are not plain solar panels or have built in 5 V regulators (both types exists), your situation might be slightly different since you can end up with light on one panel and not the other and of the panels are connected in parallel, your will feed 5 V on the output on all of them. They may or may not like this. If you get three panels and three regulators, I see no problem since the charger modules have constant current output.
In case your panels are smart with buil-in 5 V regulation and might be damanged by 5 V on the output with no light on the panel:
In case your solar panels are just panels with no internal regulation:
