LONGi LR5-54HPB-410M 410W Solar Panel (108 Half-Cell) – 1000V Black/Black Module
The LONGi LR5-54HPB-410M 410W is a high-performance monocrystalline solar panel designed for reliable energy production in residential rooftops, small commercial systems, and off-grid solar applications. Featuring a modern 108 half-cell (HC) layout, this module is engineered to reduce power loss, improve efficiency, and maintain steadier output in real-world conditions such as heat, partial shading, and changing sunlight.
With a 410-watt power rating, the LR5-54HPB-410M delivers excellent power per panel—helping you reach your target system size with fewer modules. The black-on-black (blk/blk) finish (black frame and black backsheet) provides a clean, premium look that blends well with most roofing styles, making it a popular choice for homeowners and installers who care about both performance and aesthetics.
Built for compatibility with standard solar system designs, this module supports a 1000V system voltage, making it suitable for common string inverter and hybrid inverter + battery configurations used in today’s solar installations.

What Is the LONGi LR5-54HPB-410M?
The LONGi LR5-54HPB-410M is a photovoltaic (PV) module that converts sunlight into DC power for use with solar inverters and optional battery storage. Its half-cell architecture improves overall efficiency by lowering internal electrical resistance and helping the panel maintain better output when parts of the panel are shaded or when temperatures rise.
In short: it’s a modern 410W mono solar panel built to deliver strong production, premium looks, and long-term reliability for everyday solar projects.

Frequently Asked Questions (FAQ)
1) What does “108 half-cell (HC)” mean?
Half-cell panels divide solar cells into smaller segments, reducing resistance and power loss. This can improve efficiency and help the panel perform better in partial shading conditions.
2) Is the LONGi LR5-54HPB-410M good for residential rooftops?
Yes. It’s a popular 410W class panel with a sleek black/black appearance and strong output—ideal for residential rooftops and standard inverter setups.
3) What does the 1000V rating mean?
It means the panel is designed to be used in systems up to 1000V DC array voltage, which is common in many residential and commercial string designs (final design depends on inverter specs and local code).
4) Does black/black mean it produces more energy?
Not necessarily. Black/black is mainly an aesthetic choice. Energy output depends on the panel’s efficiency, wattage rating, and your system design, tilt, and sunlight conditions.
5) Can I use this panel with batteries or an off-grid system?
Yes. This panel can be used in hybrid or off-grid systems when matched with the proper charge controller, inverter, and battery storage sized for your system needs.
