Renogy 550 Watt Monocrystalline Solar Panel, UL Certified


  • High-Powered Module:   This solar panel is engineered with high-efficiency PERC (Passivated Emitter and Rear Contact) cells, capturing more light to achieve 22.8% conversion efficiency. Resulting in higher performance than most conventional panels, Renogy's 550 watt panels provide more output per surface area.
  • High Tolerance:   Renogy's high-powered 550 watt solar panels are made with half-cell technology. This half-cut panel is more tolerant of shading on any part of the cell and performs excellently in low light situations due to the increased number of cells receiving more sunlight.
  • Space and Installation Optimization:   A great option for large-scale installations, each solar panel can produce up to 2750 Wh of electricity per day and requires fewer installations per panel on your rooftop, making it the ideal choice as home solar panels.
  • Reliable and Durable:   Corrosion-resistant aluminum frame provides extended outdoor use that ensures the panel can last for decades. The IP68 rated junction box and solar connectors can withstand dirt, dust, debris, and water splashes.
  • Claim Federal Solar Tax Credit:   Claim up to 30% of your home's new solar system costs (both equipment and installation) for solar panels tax credit. To learn more about the Investment Tax Credit, please refer to our Solar Tax Credit section or visit the designated U.S. Department of Energy webpage.
