The LONGi Hi-MO 9 Sea-Shield LR8-66HYD Solar Panel range is engineered for powerful energy generation and long-term reliability in demanding, high-corrosion environments. Available in outputs from 630W to 670W, the range combines high-efficiency BC-cell technology with a bifacial design to achieve module efficiencies of up to 24.8%, while its specialised Sea-Shield construction makes it particularly suitable for coastal, offshore and other high-humidity applications. A salt-spray-resistant modular junction box, weather-resistant dual-layer coated glass and specially designed anodized aluminium frame provide enhanced protection against salt corrosion and harsh environmental conditions. With a positive 0–3% power tolerance, less than 1% first-year power degradation and only 0.35% annual degradation from years 2–30, the Hi-MO 9 Sea-Shield range is designed to deliver dependable energy production over the long term. Robust construction, up to 5400Pa front-side static loading, 1500V system compatibility and operation from -40°C to +85°C further support demanding solar installations, while a 12-year materials and processing warranty and 30-year extra linear power output warranty provide added long-term assurance.
