Sharp ND-167U1, 167 Watt PV Module Designed specifically for peak roofs, Sharp's ND-167U1 solar panels offer industry-leading performance and aesthetics. These residential solar panels give the clean, attractive appearance of a high-tech skylight while the black anodized aluminum frames and trim strips blend beautifully with the home's exterior. In addition, an "L" hook design located along the frame's perimeter ensures easy integration with the residential system mounting hardware. Perfected by Sharp's nearly 45 years of research and development, these modules allow for maximum usuable power. An anti-reflective coating provides a uniform blue color and increases light absorption in all types of weather condtions.
