Solar Panels, 800 watts of mix brand
name modules, Four are Evergreen 115
watt. Two are Sunwize 90 watt and the top
two are Shell 85 watt. All of the above
modules are 17.1 and 17.2 volt panels. I
have paired them into twos to create a 24
volt array. Then they are all connected
together to build amps. As long as your
voltage and amps on the modules are the
same you can group them or pair them. In
parallel the amps add and in series the
volts add. As in the solar panels pictured.
The solar panels are matched up with

panels with like amps and volts in series. Then the 4 sets of two modules are hooked in
parallel to add up the amps. This minimized any loss.

Side Note
If you put a 16.5 volt 8 amp solar panel with a 17.2 volt 7 amp panel wired in parallel, you will
get 15 amps at 16.5 volts. If you were to wire the same two solar panels in series it would add
voltage so you would have 33.7 volts but would only have 7 amps. You lose amps when you
wire in series and you lose volts wired in parallel.
If you have an 8 amp solar panel hooked to a 7 amp panel, the 7 amp is the bottle neck. You
can not push 8 amps of current through an opening that was made for 7 amps. So that is why
you would have 7 amps at 33.7 volts. Really there is more to it but that is the simple way to put
it. These two solar modules will not match at all in parallel or series. You would need a
charge controller for each.
