LONGi 545W Mono — Silver Frame (LS72-545M)

LONGi 545W Mono — Silver Frame (LS72-545M)

The LONGi LS72-545M is a 545W monocrystalline PERC solar panel that offers excellent value and proven reliability for residential and small commercial solar installations. Built on LONGi's mature half-cut PERC cell technology with a classic silver anodized aluminum frame, this panel is a workhorse — straightforward to install, compatible with virtually every inverter on the market, and backed by LONGi's best-in-class warranty program.

With 72/144 half-cut cells and a 35mm deep frame that adds structural rigidity, the LS72-545M is particularly well-suited for roof-mount arrays where durability under heavy snow loads matters. Its single-glass construction keeps weight manageable while delivering consistent, reliable output over decades of service.

KEY FEATURES • 72/144 half-cut monocrystalline PERC cells — proven, reliable technology • Up to 21.3% module efficiency • 35mm deep anodized aluminum frame — exceptional rigidity for heavy snow regions • Single glass with UV-stabilized polymer backsheet • Snow load rated to 5,400 Pa, wind rated to 2,400 Pa • IP68-rated junction box — fully sealed against moisture and dust • Positive power tolerance — guaranteed at or above rated output • Excellent compatibility — works with all string and hybrid inverters • Ideal for pitched roof arrays where rear-side gain is not a factor • Operates from −40°C to +85°C — built for Canadian winters
