Solar ac output question

[jespo27]

I am trying to figure the ac power output of 25 sanyo 200w panels. I was told to take the cec (?) value of one panel , multiply that times the number of panels , multiply that number times the average efficiency of an inverter 95% and that should equal the ac output of the system.
I cannot find the cec(?) value of these panels. Is my terminology wrong?

CEC is one of the harder to come by figures, when it comes to PV. Most websites don't list it, they just list Pmax and Pmin. Fortunately, CEC is always extremely close to the average of Pmax and Pmin. The 200 watt Sanyo BA3's Pmax and Pmin, compared to that same panel's CEC shows that to be true.

Now that we have that out of the way, you'll need to multiply that by the number of panels you'll have installed, then by the number of hours of usable sunlight/day (usable for producing electricity with EV panels, which is ~5 hrs/day here in Dallas), and then finally by the efficiency of your inverter, whatever that happens to be.

Of course, your inverter's efficiency may very well not be 95%. Inverters aren't usually that efficient, and their efficiency can vary by a considerable margin, so use 90% as a baseline, even though they can go as high as 95%, they can also go as low as 50%. So, if I buy ten BA3's, my equation would look like this: 188.3 x 10 panels x .90 (90%) x 5 = 8,473.5 watts of AC/day.

Just make sure to only use the cheaper modified sine wave inverters for things like lighting, microwaves, etc, assuming you can afford a more expensive true sine wave inverter for all of your electronics, plus your electric motors. Neither electronics nor electric motors like modified sine waves. Motors will run hotter, and use considerably more electricity, and quite a few electronics (that goes triple for computers) just don't last very long at all, when ran with a modified sine wave. Good luck.

edit: PV= photovoltaic, which is just another way of saying solar panels
