Its like a chain....the weakest link dictates maximum power by virtue of the fact that one of them may have less current capacity.
Here's an analogy.
Imagine stringing together three garden hoses together...but the middle hose is thinner than the other two.
Maximum flow would always be limited by the thin hose....no matter how thick the other hoses are.
Hope that makes sense?

Yes. so what are you suggesting.. serial another 80 W panel or 20W is sufficient?
What would be the drawback of mixing panels of various watts.Leave a comment:

6" x 6" cells? Yeah... those might be 0.63 Voc per cell, 0.5 Vmp, so you are only at 10 V. You would need ~36 of those cells in series to charge a 12 V battery.

20 cells, 4.6 Watts per cell
my problem is the my controller is not showing any panel.. insufficient voltage I assumeLeave a comment:

You are mixing up voltage and current, making it hard to understand your problem.
Sunpower has a 475 W panel coming, but that won't work with a 30 A PWM controller either.
What cells did you use to build your panel?Leave a comment:

Best Watt per panel
what is the best Watt per panel as there are various offer in the market varying from 10 to 100 watts per panel..
I have built an 80 watt panel and found out that it produce less than required current (V) and therefore it is not recognized by the controller (30A PWM).
So what do I need to add? serial another 80 watt panel or just add 20Watt to produce 12Volts current?
Is it possible to mix panels of various watts?
