Shipping to many States is aprox $450 per pallet.

We are also planning a few trips in different directions and can deliver with our trailer if it is a few pallets for cheaper, just send a mesage.

Astronergy CHSM6612P-325​

This are PERC panels, so they show as polycrystaline, but this is a completly different method that the old poly panels, these are high end productione units you can read about all the new types of silicon productions here: https://www.cleanenergyreviews.info/blog/most-efficient-solar-panels

So, I'm looking at their specification sheet for this model, and a lot of the specs don't line up with what you have posted above.
Do you have an alternative spec sheet, or where is the discrepancy coming from? For one thing the temp coefficient of voltage is more than double what you specify according to the manufacturer

Hi Robert.
I copied and pasted from a website selling them, they were listed in Kelvin versus the datasheet in Celsius.
The the temp coefficient of voltage in the datasheet is - 0.311%/°C as a percentage of C. I am not that familiar with this coeficient since it is open circuit which it is basically a non usable parameter as far as I know. I listed "Temp. Coefficient of Power -0.41%/K" the data sheet shows " - 0.408%/°C" which it is standard when listing two instead of three decimals. The temp coefficient of power is what we use to calculate temp output difference, but thank you for the catch.
I will edit the post tonite.
Meanwhile here is the datasheet at manufacturer website: . I will also post the label behind the panels just in case.


These are overordered panels from a 20megawatt solar farm, new never installed

Thank you Robert, I have edited the post to show the voltage ratings stated in the label on the back of the panels, which I have posted also. I have linked the data sheet and edited the temp coefficients on the post.

I believe the open circuit voltage temperature coefficient comes into play when you're dealing with the voltage rise of the panels in the morning when it's very cold out; the voltage could potentially rise enough to cause issues with your equipment if you specced the panels very close to the maximum OC voltage of the gear. It's a niche issue for sure, but thanks for the update.

Thanks a lot for the explanation, i learnt something new. Had never heard of it.
