Anker SOLIX RS40B 410W Solar Panel - 23% Efficiency

Anker SOLIX RS40B 410W Solar Panel is a rigid module designed for fixed outdoor solar installations rather than foldable charging. The panel combines a 410W rated output with 23% efficiency and an IP68 protection rating.

Core Specifications and Design

The RS40B uses PERC photovoltaic technology and measures 1722 x 1134 x 30 mm. Its published electrical figures include a 37.32V open-circuit voltage, 31.45V voltage at maximum power, and 13.04A current at maximum power, as listed in the RS40B technical specifications.

Each panel weighs 20.5 kg and carries IP68 dust and water protection. The listed operating temperature range is -40 C to 85 C, giving the module a specification suited to permanent exterior mounting.

Output and Installation Context

The RS40B is sold in a two-panel configuration in the documented Anker SOLIX listing, with 410W assigned to each module. A two-panel setup therefore carries an advertised 820W peak rating when the panels are combined, while the RS40B module itself remains a 410W panel.

The panel dimensions create a broad, rigid mounting surface rather than a compact travel format. Its 30 mm thickness, 20.5 kg weight, and IP68 rating are relevant for balcony, patio, roof, and other fixed installations where the mounting structure must support a full-size framed module.

Anker lists a 12-year product warranty and a 25-year performance guarantee retaining at least 84.8% of initial output. The manufacturer's RS40B specifications identify the panel as a 410W PERC module with the same dimensions, weight, efficiency, protection rating, and warranty terms.

US Market Position and Price

The US Anker SOLIX storefront lists a two-panel 410W rigid solar-panel package at $999.00 as of 09/24/2026. That listing places the configuration in the fixed-panel segment, alongside Anker SOLIX power stations and home-backup equipment.

For US operations, Anker's terms identify Fantasia Trading LLC in Bellevue, Washington, as the default US entity and Anker Solix Limited in Ontario, California, for SOLIX products. The US contracting-entity details distinguish those American entities from Anker Innovations Limited.

Best Fit for Fixed Solar Systems

The RS40B fits users planning a permanent solar array with a rigid 410W module, a 23% efficiency rating, and IP68 protection. Compared with Anker's 200W portable panel format, it provides more rated output per module but gives up foldability and the lighter form factor associated with portable equipment.

The key limitation is installation: a 20.5 kg panel measuring 1722 x 1134 mm requires a suitable mounting surface, compatible electrical hardware, and attention to local installation requirements. It is better suited to fixed balcony, patio, roof, or backup-power systems than to camping or frequent transport.
