LONGi Hi-MO 5 540W Bifacial Monocrystalline Solar Panel LR5-72HBD
R2 760.00 incl. VAT
The LONGi Hi-MO 5 540W Bifacial Solar Panel captures sunlight on both sides — boosting real-world energy yield by 8–25% compared to monofacial panels on light-coloured rooftops and ground-mounted systems. At 20.9% cell efficiency, it’s one of the most efficient 540W modules available in South Africa.
Half-cut PERC n-type cells deliver superior low-light performance — generating measurable power from early morning, late afternoon, and overcast SA winter skies. 30-year performance warranty (80.4% at year 30) — the longest in the industry. IP68 waterproof junction box, 12-year product warranty.
Ideal for ground-mount systems, tin/IBR rooftops, and commercial installations where maximum energy density is critical. Price excludes VAT. Bulk pricing for 10+ panels on request.

What Is the LONGi Hi-MO 5 540W Bifacial Panel?
The LONGi Hi-MO 5 (LR5-72HBD-540M) is a 540Wp bifacial monocrystalline PERC solar panel from LONGi Solar — the world’s largest solar manufacturer by module shipment. The “bifacial” design features active PV cells on both the front and rear surfaces, allowing it to capture sunlight reflected from the mounting surface (roof, ground, concrete) for additional power generation.

Bifacial Gain in South African Conditions
Bifacial gain depends on what’s below the panel. On a white-painted IBR or corrugated iron roof (common in SA), expect 10–18% more energy per panel compared to monofacial. On galvanised (silver) roofing, 8–12% gain. On ground-mounted systems with light gravel or concrete, 15–25% gain. Over a 25-year lifespan, this translates to thousands of additional kilowatt-hours per panel.
30-Year Performance Warranty
LONGi’s 30-year linear performance warranty is industry-leading — guaranteed 80.4% of rated output at year 30. Compare this to the standard 25-year warranty offered by most competitors. For a homeowner installing 8 panels today, LONGi’s extra 5 years of warranty coverage represents meaningful financial protection.

Christo van Wyk –
The LONGi Hi-MO 5 540W Bifacial Monocrystalline Solar Panel LR5-72HBD panels look great on the roof and the output has been consistent. In peak summer we are generating far more than we consume and exporting the rest. Panel frames are robust and the surface is very easy to clean.
Riaan Botha –
We installed LONGi Hi-MO 5 540W Bifacial Monocrystalline Solar Panel LR5-72HBD panels on our north-facing roof and the production has exceeded expectations. Electricity costs have dropped by over 60 percent. PowerVault was helpful in confirming the right panel count for our system and delivery was on time.
