315w & 340w panel dimensions

[preilly44]

Does anybody know the sizes of the 315w and 340w panels? I just got a quote from Tesla for the 340w panels on my guest house (we are getting the SGR for the main house) and Tesla only quoted a 5.44kw system using the north and south side of the roof. I have a current system (from another company) with 275w panels (only on the south side) and that is 4.125kw. Tesla can't fit as many panels on the south side of the roof, I'm guessing because of the size of the 340w panels.

I just asked Tesla to redesign the system with 315w panels to see if they can fit more panels. I was hoping for an 8kw system when using both the north and south side of the roof.

There’s not a huge difference, but a little might be all you need.

The 315W panels are listed as:
1685.0 mm L
1000.0 mm W
32.0 mm D

The 240W panels are listed as:
1740.0 mm L
1030.0 mm W
32.0 mm D

Do the new panels have the same look as the old ones? Still black?

*340 watt, and yes. Some are made in Dalton, Georgia. Some are made in South Korea. Last I heard most of the G6+ were made in Dalton.

Just to update the thread, they were able to get me up to 7.25kw from 5.44kw by going with the smaller 315w panels instead of the larger 340w panels.
