Suggest merge

Suggest merging the articles Constant voltage method, Incremental conductance method, Perturb and observe method to this article. The reader gets very little extra information from these stubs and it would seem to be more rational to be comparing the algorithms here. --Wtshymanski (talk) 15:34, 27 February 2012 (UTC)

• Oppose The individual articles have enough info in them to have articles on their own. 03:54, 16 March 2012 (UTC)
Well, if there's a lot of content to be added, we can always spin out those sections when they grow and leave a summary here; but right now there's not enough content to warrant splintering the few facts and repeating them in two places. --Wtshymanski (talk) 13:21, 16 March 2012 (UTC)

I - V term usage?

I know this term applied as I/V for for the curves may look confusing but isn't this the proper terminology for a current over voltage charted curve? This format appears t be used in many other places in the article for other terms. There must be a way to make the format for these terms match the format used elsewhere for the rest of the terms. Will it look like a Mho formula and isthere a way to identify it as not a Mho formula with proper wording? 174.118.142.187 (talk) 02:30, 28 October 2012 (UTC)

I haven't found anything in the WP:MoS clarifying any line chart formats but the Line chart article has some usage samples mentioned like this "I versus V curve" (or "I vs V curve") and "I(V) curve". 174.118.142.187 (talk) 03:11, 28 October 2012 (UTC)

exponential?

The page says "A photovoltaic cell has an approximately exponential relationship between current and voltage".

Eh? That would imply the current increased as the voltage increased. The curve looks nothing like an exponential. I suggest rewriting to say whatever was meant in a clearer way that will be understood by readers. — Preceding unsigned comment added by 131.111.85.79 (talk) 11:51, 1 November 2012 (UTC)

I choked on that statement, also. It's pure mathematical BS. The current is not related to the voltage for most of the curve. The curve is a well defined, and an almost perfect constant current source. The current is basically constant (depending on energy source parameters, of course) and never varies much up to the voltage saturation point, regardless of load resistance. This is why many different panel ratings and breeds can be parallelled so easily regardless of size and current rating. This is a classic constant current source description. Refeences would be good. 174.118.142.187 (talk) 17:47, 1 November 2012 (UTC)
I have clarified the curve description. See if it appears better to you now. 174.118.142.187 (talk) 18:35, 1 November 2012 (UTC)

MPPT as a motor starter

What is this section even doing here? What's being described isn't an MPPT, it's just a power converter. I'm going to change this to just mention that MPPT is usually integrated into the power system. If you can justify why it should be here, please do and show references.

This sounds like the same circuitry and the same function performed but for a different purpose. I think if it is not finding the MPP then you're correct to remove it. Mention could be made but... naah. 174.118.142.187 (talk) 23:13, 7 November 2012 (UTC)

mgshightech: You can't have mppt without dc-dc conversion because the battery only accepts a narrow range of voltage, and your panels are trying to deliver a different voltage at maximum power, once you are dc-dc converting, you get mppt simply by choosing the proper duty cycle on your pulse width modulated transistors.
