Sharp NE-80EJEA 80 watt solar panel Sharp's NE-80EJE solar panel offers industry-leading performance, durability, and reliability for a variety of electrical power requirements. Using breakthrough technology perfected by Sharp's nearly 45 years of research and development, these modules use a textured cell surface to reduce reflection of sunlight, and BSF (Black Surface Field) structure to improve conversion efficiency. An anti-reflective coating provides a blue color and increases the absorption of light in all weather conditions. Designed to withstand rigorous weather conditions, a junction box is also provided for easy electrical connections in the field, making Sharp's NE-80EJE solar panels the perfect combination of advanced technology and reliability.
