Do you have a list of your solar panels that you would classify as low-voltage panels? I primarily install off-grid systems so I'm interested to see a wide list of panels that would be well suited for this type of installation. Specifically, I need to be able to find and sort modules that are rated for 12VDC.

If you look at the upper left of Greentech Renewables page, you'll see the "Products" tab. In the roll down menu, click the solar panels. On the left hand side of the page, you'll notice that you can search the panels by Watts.
Most of the modules under 150W are 12 V modules.
Alternatively, you can call or e-mail and get an up to the minute list of all 12VDC modules and their price/availability.
Greentech Renewables is also working on some advanced module search features which will be available soon.
This may be obvious, but modules, like batteries are only "nominally" 12V.
The so-called-12V-panels are in fact around 17-18 Volts Open Circuit.
Sorry if this sounds condescending - not intended - just be sure to search in the 17-18 volt range as well.
