LONGi Solar S10 490W Ecolife Mono All Black SDM1 Solar Panels
- Generate 490W per panel at standard test conditions, with 24.0% module efficiency for projects where available installation space matters.
- All-black double-glass construction with back-contact cells and a black anodised aluminium frame.
- 30-year linear power-output warranty, with 88.85% guaranteed output at year 30, subject to LONGi’s terms.
LONGi S10 490W all-black SDM1 solar panel
The LONGi S10 490W Mono All Black SDM1 solar panel, model LR7-54HJBB-490M, combines back-contact cell technology with double-glass construction for residential and suitable commercial PV installations. It delivers 24.0% module efficiency in a 1,800 × 1,134 × 30mm format and weighs 23.5kg.
Key features
- Space-efficient generation: 490W rated front-side output and 24.0% module efficiency help make effective use of the available array area.
- All-black appearance: back-contact cells and a black anodised aluminium frame suit visible rooftop installations.
- Double-glass construction: 2.0mm front glass and 1.6mm rear glass, with the potential for additional generation where reflected light reaches the rear.
- Temperature performance: a maximum-power temperature coefficient of −0.240%/°C supports accurate assessment of output changes as cell temperature rises.
- Long-term performance cover: less than 1% first-year degradation and 0.35% annual degradation in years 2–30, under the manufacturer’s linear power-output warranty terms.
Where to use
Consider the LONGi S10 490W all-black panel for residential roofs, commercial offices, warehouse administration buildings and other suitable rooftops where module appearance and installed capacity matter. It can also be used in professionally designed carport or ground-mounted arrays.
Rear-side generation depends on reflected light, mounting clearance, shading and the final array layout. Do not assume an additional energy gain for a close-mounted roof installation without a site-specific assessment.
Use mounting hardware approved for the exact module dimensions, frame profile and fixing positions. Energian can help with module quantities, inverter string design, mounting compatibility and DC protection. The panel requires professional system integration; installation can be arranged through trusted partners.
