550 watt Mono Solar Panel Specification
The 550 watt Mono solar panel is a monocrystalline PV panel with an efficiency of 21.28%. It is one of the most mainstream PV panels used in large-scale PV systems such as residential PV systems, industrial PV arrays, commercial PV systems, grid-tiedPV arrays, PV farms, and other large-scale PV systems. Its high-power output can minimize the cost of PV system installation and operation and maintenance.
One 550w PV panel can generate about 2kWh~3kWh of electricity per day (it depends on the average sunlight radiation in your area). You can also use our PV System Calculator to calculate the total power you need for your PV system.

Features of 550watt Mono Solar Panel
The latest PERC technology ensures high output and less than 1% annual decay rate.
Half-cut process, where the traditional one-piece PV panel is made into two parts. This way, even if one of the parts is blocked by shadows and cannot generate electricity, at least 50% of the electricity is generated.
Junction box, MC4 connector IP67 waterproof and dustproof rating, in the sandy and dusty areas, rainy areas, such as the Middle East, Southeast Asia, and other coastal areas IP67 protection level is essential.
Salt spray resistance standard, PV panels through the salt spray test, and in the test report the indicators are within the normal range.
Passed EL test, no hot spot effect, which ensures the quality of PV panels and reduces the failure rate during use.
550watt high power, can meet the demand of large power station for high power output. We also have 600watt and 700watt PV panels.
Wind load 2400Pa, snow load 5400Pa. In Northern Europe, North America, plateau and other windy and snowy areas, the PV panels can also easily cope with this extreme environment.
Warranty, the panel’s annual attenuation rate is less than 1%, and it can still maintain a power output of over 440 watt for 25 years.
550 watt Solar Panel Size
The size of 550 watt is 2279*1134*35mm. This is the most suitable size for container transportation. In addition, we also provide customized PV panel size, power and voltage service. If you need to purchase small quantity or large quantity of customized PV panels, please contact us.
550 watt Mono Solar Panel Price
Price of 550 watt mono solar panel is around $55. This is the price without tax and shipping. Please contact us for a discounted price for delivery to your door. Because it is a factory direct quote, our quote varies with the price of raw materials for PV panels.
