The surface area vs power rating is believable*, but that doesn't mean it actually does it of course and there are more things to consider than just power output such as will it actually last more than 5 years.

*1648x 990 / 300 = 0.00018, well known quality brand mono panels range from 0.00018 - 0.00022 in my experience.

thats a neat metric to gut check datasheets!

looks like efficiency. surface area / power x (energy in sunlight / per unit area)

Found these on SantanSolar: CSUN310-60M-BB 310W @ $140 https://store.santansolar.com/product/csun-310w/

They look nearly the same to the BSM300M-60 but they are not UL 1703 certified.

The Blue Sun BSM300M-60 say they are UL 1703 listed, going to check for certification since I'll have to submit it with the permit application.

Also curious about the Mission Solar 310W @ $135 https://store.santansolar.com/product/mission-solar-310w/ , they say they are new but grade B, wonder if the mfg warranty applies - emailed to ask. They are Made in USA which is nice and UL 1703.

Bluesun / Solarhome sent the UL 1703 certificate quickly. Waiting to hear back on certificate verification.

SanTan solar says no mfg warranty but they provide a 1 year warranty.

Anyone know of new panels better than $0.45/watt ? What about used panels?

Sure, same vendor with used panels for $0.22/watt, manufacturer label (presumably UL) still intact:

Canadian Solar 255W - SanTan Solar Store SanTan Solar Wholesale Solar Panels

255W Canadian Solar, only $55 ($0.22 per watt)! Perfect for a DIY solar panel kit. Best wholesale solar prices available!

But under "additional information" it says "Off-Grid", which I though was used for no UL label; ask for clarification. He did not say "off-grid" under description, so that may have been a mistake.
Tell him how many you're interested in, ask what price he'll let you have them for.
Freight shipment of a pallet is probably between $150 and $300, so one or more pallets of about 25 panels each is the best deal.

Funny they can not spell where their warehouse is.

Got the UL 1703 certificate verified!

I'll follow up on the Canadian Solar - if they can be used On-grid, on-roof seems like a potential deal..
