450 watt Mono Solar Panel Specification
450 watt Mono solar panel is composed of 120 pcs monocrystalline silicon cells. The excellent quality of the product makes it widely used in homes, villas, grid-tied PV systems, off-grid systems, hospitals, schools, large-scale PV arrays and other fields.
A 450w PV panel can generate approximately 1900Wh of electricity per day, you can calculate the number of panels you need based on your monthly electricity consumption. You can calculate the number of panels you need based on your monthly electricity consumption or use our solar Calculator to calculate the size of the PV system you need.
In addition, 400 watt PV panels are also available as double-glazed or all-black modules. The double-glazed modules utilize the back side of the panel to generate electricity, which is more efficient. The all-black modules have a more attractive appearance.

450 watt Mono Solar Panel Features
20.79% Power Generation Efficiency: Greater power generation efficiency makes PV panels less costly and affordable.
Aluminium Alloy Frame: Its stronger hardness and rust-resistant properties make it the best frame material for PV panels. It can well protect the appearance of PV panels from being damaged.
Small impact by temperature change: the use of PV panels in a wide range of temperatures, and the ambient temperature in the 25 ℃ standard for each decline or rise 1 ℃, the efficiency of the PV panel is reduced by only 0.35%.
IP68 waterproof and dustproof junction box: The ultra-high waterproof and dustproof level ensures that the PV panels can generate electricity normally even under extreme conditions.
Half cut technology: PV panels are upgraded from a single block to two parts, so that when one part is covered by the shadow, the panel can still maintain 50% of its power output.
