my final solar panel i use Aluminum

This is the first time i bringing the PROFESSIONAL solar panel aluminum frames that all real solar panel manufacturers use - the extruded, anodized aluminum frames designed to fit 108 of the 3x6 solar cells, with the 5columns  configuration. i can easily cut the aluminum frames down to the sizes that i want, whether it's the popular 24 cell   other custom sizes that i have. These frames come with 4 "corner keys" that are L-shape pieces that are used to connect the the frames in a 90 degree angle, and because the corner keys are graduated and they tighten the connections when hammered in - no screws are used. The frames are anodized to provide excellent corrosion resistance in harsh weather. The frames are EXACTLY the same frames as those used on the Spruce Line string ribbon solar panels (Google Spruce Line photovoltaic modules), in fact we got all of remaining frames DIRECTLY from the original panel manufacturer, so the mounting holes, grounding wire holes, dimensions, etc. are all in the right sizes and right places!
