LONGI 450W SILVER MONO solar panel - pallet of 30 pcs

The high-performance LONGi 450 W Silver Mono photovoltaic panel (LR4-72HPH-450M) is a proven and reliable solution for residential, commercial and B2B projects where high efficiency, long-term operating stability and a renowned Tier-1 manufacturer brand are key. The module is designed to maximise energy yield and provide trouble-free operation for many years.

The use of monocrystalline cells with Low LID Mono PERC Half-Cut (Hi-MO 4m) technology delivers excellent performance even at elevated temperatures and under partial cloud cover. Low LID technology limits first-year degradation (<2%) and guarantees a linear power decline of 0,55% per year.

Robust construction and precise workmanship ensure high mechanical resistance (up to 5400 Pa front / 2400 Pa rear) and stable energy production in changing weather conditions. The long manufacturer’s warranty and full compatibility with modern inverter and monitoring systems provide peace of mind from day one.

Key features – why choose it

- Renowned manufacturer LONGi (Tier-1) = investment security
- 450 W = a very good balance of power and dimensions
- 1500 V DC = ability to build longer strings and reduce BOS costs
- Low LID technology = slower power degradation
- High mechanical resistance = safety in snow and wind
- Stable temperature performance = predictable output in summer

Note: The aluminium frame may have slight discolouration.
