This listing is for brand new Avancis 115 watt solar panels. These are extremely well built panels that are made in Germany. They are all black and have mounting flanges on the sides for clamps and predrilled holes on the back for bolting them down. They have a max power voltage of 42 volts DC and a open circuit voltage of 59 volts and the panels are 63" tall and 27" wide. These work great for grid tie systems or for charging batteries with a good charge controller. It takes less panels in a string to get up to a high voltage for grid tie and they will very quickly get up to a charge voltage for charging batteries. I have a variety of different size charge controllers too. The charge controllers size depends on how many panels you would want to have. You can call, email or text me if you have any questions.
