I noticed that that the Renogy 300W panel has the PERC tech, will there be other panels with that tech, available, in the very near future. Also I have read about the half cell technology, will that be showing up in any of the Renogy panels, in the vey near future.
I am considering replacing my 2 x 50W panels with maybe a bigger panel, but I want to keep by system basically at 12V. I am still unclear that, if I were to replace it with the 300W panel, if that would scale into my 12V system, correctly.

The 300 watt panel (as you know) is a 24 volt panel. So, as long as you are using it with an MPPT controller, it shouldn't be a problem. Keep in mind that you can't connect other 12 volt panels to the same controller unless maybe you put two panels in series for 24 volts.

Thanks, I was kind of thinking that that would be the case. Not ready to split up the system to support a 12V and 24V flow. Well, at least I am not ready just yet.
I am still thinking about the best way to maximize the solar panel spots that I have for the greatest solar input. Now, in retrospect, maybe I should started with a 300W panel in the beginning. Then again when you think about it, will the solar panels get to, maybe 400W or 500W. I hate tis idea of replacing existing solar panels with the next big thing.

I have noticed that Renogy is selling a compact 100W panel. A question for the Admin, is their a 300W compact panel in the works, with the PERC tech, of course.

At this point in development we are not sure whether other models will expand to have PERC technology. Utilizing a 300W panel with an MPPT will be appropiate for charging 12V systems. Additionally, a compact, PERC 300W panel is not in the works. |

Since I am limited for panel space, I am always looking for best watts from a panel. The 270W and the 300W panel have the same frame size, not the same price, but you pick up some 30W. Not sure if the PERC tech adds to the 30W difference, or it just improves the current flow in low light situations.
I am glad to hear that the 300W panel would work with my 12V system setup, using my existing Rover CC. Still thinking about how to mix in my existing 100W panels. Is the Rover CC smart enough to figure out what to do with a 300W and a 100W power source.

A 300W panel and 100W panel need to be connected in parallel into an MPPT controller or you will miss out on some amps if connecting in series. Minimum size would need to be a ROVER30 |
