LONGi 500W All Black Bifacial — (LR8-54HGBB-500M)

The LONGi LR8-54HGBB-500M is a 500W all-black bifacial solar panel that combines the aesthetic appeal of a fully black module with LONGi's advanced N-Type TOPCon cell technology. Designed for homeowners and builders who demand a clean, low-profile look on residential rooftops without sacrificing efficiency, this panel's black frame, black backsheet, and dark cell surface deliver a sleek appearance that blends beautifully with modern rooflines — while still capturing energy from both sides of the glass.

At 500W with up to 21.5% efficiency, the LR8-54HGBB-500M is a compact but powerful 54-cell module. Its smaller physical footprint makes it ideal for roofs with tighter available space or where a premium aesthetic is the priority.

KEY FEATURES • Full all-black aesthetic — frame, backsheet, and cells • N-Type TOPCon bifacial — up to 21.5% module efficiency • Bifacial design captures reflected light for additional energy yield • 54/108 half-cut cells — reduced resistive losses and better shade tolerance • 30mm black anodized aluminum frame — sleek and durable • Dual-glass construction — improved longevity, no PID degradation • Snow load 5,400 Pa, wind load 2,400 Pa • Ideal for new builds, visible roof locations, and premium installs • Positive power tolerance (+0/+5W) • Operates −40°C to +85°C — perfect for Canadian climate
