LONGi 450W Silver Mono Photovoltaic Panel

The high-efficiency LONGi 450W Silver Mono photovoltaic panel (LR4-72HPH-450M) is a proven and reliable solution for home, commercial installations and B2B projects where high efficiency, long-term operational stability and a renowned Tier-1 manufacturer's brand are crucial. The module has been designed for maximum energy efficiency and trouble-free operation for many years.

The use of monocrystalline cells in Low LID Mono PERC Half-Cut technology (Hi-MO 4m) ensures very good performance also in conditions of elevated temperature and partial cloud cover. Low LID technology limits degradation in the first year of use (<2%) and guarantees a linear power decline of 0.55% per year.

Solid construction and precise workmanship guarantee high mechanical resistance (up to 5400 Pa front / 2400 Pa rear) and stable energy production in changing weather conditions. A long manufacturer's warranty and full compatibility with modern inverter and monitoring systems ensure peace of mind from the first day.

The most important parameters – why it is worth it

- Renowned manufacturer LONGi (Tier-1) = investment security
- 450 W = very good balance of power and dimensions
- 1500 V DC = possibility of building longer strings and reducing BOS costs
- Low LID technology = slower power degradation
- High mechanical resistance = safety in snow and wind
- Stable temperature operation = predictable production in summer

Note: The aluminum frame may have slight discoloration.
