About This Product

HI-MO X10 EXPLORER LR7-54HVH 475M is a Longi Hi-MO X10 Explorer series solar panel rated at 475W under STC. It uses Longi back-contact cell technology, which places the cell contacts away from the front face to help improve active light capture and keep the panel face clean in appearance. This model is from the LR7-54HVH range and is designed as a high-efficiency residential and light-commercial module for standard grid-connected solar systems.

Who This Product Suits

This Longi panel suits homeowners, installers and small commercial jobs where roof space is limited and a higher wattage panel is preferred. It is a good fit for modern string inverter or optimiser-based systems where the electrical design is matched to the panel voltage and current. The panel also suits customers who want a recognised solar brand rather than an unknown budget module.

Specifications Explained

The 475M version is rated at 475W, with a module efficiency of 23.3%. Key electrical figures are Voc 40.18V, Isc 15.03A, Vmp 33.16V and Imp 14.33A, which are the values installers use when checking inverter string sizing and current limits. The panel has a 0 to +3% power tolerance, a Pmax temperature coefficient of -0.260%/°C, an IP68 junction box with three diodes, Class II protection, a 1500V DC maximum system voltage and a 25A maximum series fuse rating. Longi lists a 15-year materials and processing warranty and a 30-year linear power warranty, with first-year degradation below 1% and 0.35% annual degradation from year 2 to year 30.

Summary

The Longi HI-MO X10 EXPLORER LR7-54HVH 475M is a high-efficiency 475W panel from Longi’s Hi-MO X10 Explorer range. Its back-contact cell design, strong electrical rating and long linear power warranty make it suitable for Australian residential and small commercial solar installations. As always, final suitability depends on the inverter, roof layout, string design and local installation requirements.
