LONGi Hi-MO 7 — 620W Solar Panel (LR8-66HGD620M)

LONGi Hi-MO 7 — 620W Solar Panel (LR8-66HGD620M)

The LONGi Hi-MO 7 LR8-66HGD620M is one of the highest-output residential and commercial solar panels available in Canada today. Built on LONGi's third-generation N-Type TOPCon cell technology, this 620W bifacial module delivers exceptional efficiency and long-term reliability — the go-to choice for homeowners, acreage owners, and commercial installers who want maximum power from every square metre of available space.

LONGi is the world's largest solar manufacturer by shipment volume, and the Hi-MO 7 represents the best of what that scale and research investment produces. With a module efficiency of up to 23.1% and a 30-year linear power warranty guaranteeing no more than 0.4% annual degradation after the first year, this panel is built to be the last one you ever need to buy.

KEY FEATURES • N-Type TOPCon cells — lower degradation and higher efficiency than standard PERC • Bifacial dual glass captures reflected light from both sides of the panel • Up to 23.1% module efficiency — more power per square metre • 10–25% bifacial energy gain depending on install surface and ground reflectivity • Half-cut 66/132 cell design reduces resistive losses and partial shading impact • 30mm anodized aluminum frame — wind rated 2,400 Pa, snow rated 5,400 Pa • Compatible with all major hybrid and string inverters • Excellent low-light output — generates usable power on overcast Canadian days • Positive power tolerance (+0/+5W) — every panel ships at or above rated output • Cold climate certified — operates −40°C to +85°C
