Draws more energy from every square metre of roof and looks uniformly black. 545 W at 24.2% efficiency, on 1990 x 1134 mm and 25 kg.
A photovoltaic panel turns light into electric current. On this model all the electrical contacts are moved to the back of the cell (back-contact technology), so the front does not have the usual metal stripes: the surface that catches the sun is larger, and the panel looks black and uniform on the roof. In practice, you obtain more energy from the same surface — something that matters when the roof is small — and the absence of the stripes also helps when part of the panel is in the shade for a period of the day.
With 545 W per module, ten panels mean about 5.45 kWp, that is the usual size of a house system. Each panel measures 1990 x 1134 x 30 mm and weighs 25 kg, a format that two people carry up onto an ordinary roof without problems. The 3.2 mm tempered front glass, the black anodised aluminium frame and the passed hail resistance test make it suitable for a climate with snowfalls and storms, and the temperature coefficient of -0.26 %/°C means small losses on scorching days. The warranty is 15 years for the product and 30 years linear for power, with 88.85% of the initial power guaranteed at the end of year 30, so even after three decades the panel remains useful.
Module with 120 N-type HPBC 2.0 back-contact cells on a TaiRay wafer, efficiency 24.2% at 545 W, footprint 1990 x 1134 x 30 mm, 25 kg, 3.2 mm tempered glass, black anodised aluminium frame. Pmax temperature coefficient -0.26 %/°C, mechanical load 5400 Pa front / 2400 Pa back. MC4-EVO2 connectors with 1400 mm cables on both polarities, which allows flexible routing between rows; it suits string inverters of 3-50 kW, in residential and commercial systems.
Suitable for a house with a small or fragmented roof, where you want maximum power per square metre and a uniform black look, as well as for commercial systems of up to 100 kWp.

Specifications confirmed from the manufacturer's datasheet
LR7-60HVH-545M is a module from the LONGi Hi-MO X10 range, built on N-type HPBC 2.0 cells (Hybrid Passivated Back Contact, second generation) made on a TaiRay wafer - a wafer with purity and mechanical strength superior to standard wafers. Being back-contact cells, all the electrical contacts are on the back of the cell, so the exposed face has no busbars; the look is uniformly black, and the active surface is maximised.
The module has 120 cells, a footprint of 1990 x 1134 x 30 mm and an efficiency of 24.2% at 545 W - among the highest values in the segment of residential and commercial modules. The front glass is 3.2 mm tempered, and the frame is black anodised aluminium. The temperature coefficient of the power is -0.26 %/degree C, better than on the usual TOPCon modules, which means smaller losses on hot days. The weight is 25 kg.
Structurally, the module withstands 5400 Pa of front load and 2400 Pa on the back and has passed the hail resistance test. The connectors are MC4-EVO2, with 1400 mm cables on both polarities, which allows flexible connection in rows. The warranty is 15 years for the product and 30 years linear for power, with 88.85% power guaranteed at the end of year 30. It suits residential and commercial systems with string inverters of 3-50 kW; the back-contact technology also brings a better tolerance to partial shading.
More energy from the same roof area: 600 W from a single module, at 23.2% efficiency, with the contacts moved to the back for a fully active front face.
Fewer parts and faster installation for the same power: 615 W per module, at 23.8% efficiency, in a panel of 27 kg and 2278x1134x30 mm.
455 W and 22.8% efficiency in a 21.5 kg panel, with cells without metal contacts on the front and low losses in heat.
The front of the panel has no metal stripes: 450 W, 22,6% efficiency and only 21,5 kg, with good behaviour under partial shading.
