I’m building a tinny home 330sq ft, how many panels would I need to power the whole tinny home
What other components do I need
Alexey Kruglov 0 01/14/2020
You need to estimate your energy usage to figure out an exact number. You will need racking, cables, batteries, charger controller, inverter .
John Mearns 0 12/08/2019
On the dimensions listed, 78.7" x 39.1" x 0.23".... are these really less than 1/4” thick or is this a misprint? I see that they are not frameless. Are they really in a frame that is less than 1/4” thick. If that is not correct, how thick (or deep) is the frame?
Alexey Kruglov 0 12/09/2019
There is an option for frame-less but we only have 35mm frame in stock right now.
Joe 0 11/27/2019
Are these frameless?

Can the 48 volt panel be used for a 12v system on a boat? Thanks.
Alexey Kruglov 0 11/18/2019
yes as long as boat charge controller can handle the this much power.
Pam Thompson 0 10/27/2019
Could these be mounted on the roof of RV? Would they have to be angled or can they lay flat?
Galyna Kruglov 0 10/29/2019
yes you ca mount them on to the roof of the RV. I think flat would be a universal solution.
Stuart 0 09/28/2019
Does this panel fold in half
Galyna Kruglov 0 10/08/2019
No It does not fold .
