Its bifacial construction can add substantial rear-side gain on reflective surfaces, and the IP-rated junction box and connectors make it suitable for long-term outdoor use. Below are concise answers to common buyer questions, plus specific details to help you decide.\u003c\/p\u003e\n\n\u003ch3\u003eHow much extra energy does the bifacial design provide?\u003c\/h3\u003e\n\u003cp\u003eThe bifacial layout harvests reflected light that single-sided panels miss, increasing daily energy depending on the surface beneath the panel.
