About product

Sunpro Power SPDG550-144M10 is a PV module fit for both residential and commercial applications. Sunpro Power engineers made the PERC 182 BIFACIAL series durable and efficient while minimizing the amount of useful space required for their operation. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

The use of half-cut cell technology is an additional perk. The solar cells of SPDG550-144M10 are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life, and enhanced efficiency in low-light conditions. The efficiency of this model reaches 21.28% — well above the market’s average. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Sunpro Power provides a 15-year quality guarantee. Stable power output is also guaranteed —a power warranty will protect you for 30 years.

  • 1500 V DC maximum system voltage
  • MC4-compatible connectors
  • 15 years of quality guarantee and 30 years of power warranty

Increased power and efficiency

PERC technology improves on an already high efficiency of 21.28 percent. The manufacturer created an efficient and highly durable model by adding a robust PID resistance and unique glass lamination on top. SPDG550-144M10 produces 550 W of power under standard test conditions.

Improved efficiency at high temperatures

Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just -0.34% for every 1.8°F increase over 77°F.

Quality and reliability

SPDG550-144M10 receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Sunpro Power is dedicated to quality, safety, and reliability to ensure you get the very best.

A panel that can handle hail, wind, and snow

This module is weatherproof due to the 1.38" frame manufactured from anodized aluminum alloy and a layer of safety tempered glass. The modules' front and rear sides can withstand loads of 5400 and 2400 Pa, respectively.
