Rich Solar says it is about 10% smaller than a standard 10-busbar 250W panel, which makes it easier to fit on tight RV, van and trailer roofs.\u003c\/p\u003e\n\u003cp\u003eThe 16-busbar cells reach up to 25.1% efficiency under 3.2 mm AR-coated tempered glass. The panel weighs 26.9 pounds, carries UL 61730, IEC 61215 and CSA C22.2 certifications, and comes with pre-attached 12 AWG leads, MC4 connectors and an IP68 junction box.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch3\u003eRich Solar MEGA 250 ONYX 250 Watt 12V Solar Panel Features\u003c\/h3\u003e\n\u003ch4\u003e16-Busbar N-Type TOPCon Cells\u003c\/h4\u003e\n\u003cp\u003eGrade A+ N-Type TOPCon cells reach up to 25.1% cell efficiency. Rich Solar notes that N-Type TOPCon technology offers lower degradation and a longer lifespan, and the 0 to +5W power tolerance means each panel delivers at least its rated 250W at standard test conditions.\u003c\/p\u003e\n\u003ch4\u003eHalf-Cut Cells and Bypass Diodes\u003c\/h4\u003e\n\u003cp\u003eThe half-cut, 16-busbar layout reduces power loss and minimizes hotspots.
