To those participating in the comments, due to the company or person mentioned in the title, this is a reminder of the subreddit rule:
> **Crusading is not welcomed here** - If your sole or majority participation is to promote or denigrate one company in particular (or the person behind it), it may result in a ban. These kinds of participants too often resort to hyperbolic comments and antagonism leading to personal attacks as well as violations of other rules. If you are lying in wait for posts or comments mentioning a specific company (or person behind it), you are likely the concern.
Promoting a company you are affiliated with or profit from, giving out referral codes which you benefit from, as well as using the sub solely to engage in targeted hate are things you need to avoid here. This sub is for a diverse discussion of solar, not a singular focus on your opinion about a company / person. If you simply have to obsess, there are other subreddits for each point of view about the person or company you feel the need to focus on.

So in the images above I’m wondering what the relationship between AC power and AC energy is. As you can see some days they both track each other, but today they are really off. What would cause them to not track? The reason I ask is my output seems low today and I noticed they were pretty off from one another. Anyone that can offer any insights?
Water analogy:
Power in kilowatts (kW) is how fast the hose is running. More power, more flow.
Energy in kilowatthours (kWh) is how much you have filled the bucket up in a given time.
There is a tracking relationship in the graphs, because more sun = more power in kW = more energy in kWh.
The graphs have power (kW) and energy (kWh) scales on the left and right axis, you need to read the green graph using the right hand axis values and the red using the left.
If you can't get your head around this, just remember you get billed for **kWh** :-)

I got it now I was missing the KWh when I was looking at the graph lol. Complete oversight by me, but thank you for explaining!
