Good tracker stow performance. Vertical position still generating 75% rating.
Commercial farm quality consistent. No string voltage mismatch issues
sunpro utility panels rock. Single-axis tracker yield crushing financial model.
desert commercial install loving heat tolerance output stays strong 110F+ days
Sunpro 590w panels crushing it. Bifacial boost from TPO roof membrane excellent
Heavy panels but quality premium. Bifacial giving free watts from roof reflection.
Good N-type degradation rate. First year barely any output loss verified.
great panels for residential use. easy to handle and mount individually
Great for large flat roofs. Bifacial adds a bit of extra production over light membrane.
Excellent output for the price. Bifacial technology really works as advertised
Good price for a 550W bifacial. Hard to beat honestly.
needed extra hands to unload but everything was packaged well
Sunpro panels are performing great on our 300kW roof project.
Good tracker stow performance. Vertical position still generating 75% rating.
550W modules mean fewer rails and clamps. Our install crew loves that.
get more power than expected especially late afternoon
desert commercial install loving heat tolerance output stays strong 110F+ days
Amazing output compared to my old setup :)
producing 600+ watts on good days with the bifacial gain. unreal numbers.
Sunpro 590w panels crushing it. Bifacial boost from TPO roof membrane excellent
Commercial MPPT fill perfect. SMA central inverter harvest maximized.

Great product No complaints
Solid investment. Output matches specs exactly across entire pallet.
Container order saved us a lot per watt. Will buy again for next site
wholesale pricing was perfect for my commercial project. great quality too.
Kids' treehouse lighting solar. Backyard reflection boosting playtime power :)
Good N-type degradation rate. First year barely any output loss verified.
love the 550W output. needed way fewer panels for my system saved on install
all black sunpro panels are gorgeous my roof doesn’t look cluttered at all
i like the build quality and the consistent output.
Amazing performance even in winter. bifacial design catches reflected snow light great
installed 31 panels and my warehouse runs mostly on solar now
Good residential high voltage 11-panel strings perfect inverter fill
Working good so far. Only been up a month but no complaints.
outperform my older modules by a lot
sunpro 595w panels awesome
sunpro utility panels rock. Single-axis tracker yield crushing financial model.
Pretty heavy but that’s normal for 550 bifacial. No regrets.
Container pricing made this utility project financially viable. Excellent wholesale value.
sunpro commercial panels are solid. Deployed on three warehouses production great.
Great panels for the money. bifacial boost is real and noticeable.
Good production. install took some time cause of roof layout but no issues with the panels.
honestly blown away by how much they generate off the backside
Heavy panels but quality premium. Bifacial giving free watts from roof reflection.
sunpro doesnt mess around. these are commercial grade and built to last decades.
sunpro makes great stuff. these are commercial grade and built to last.
Performs better than some Tier 1 brands we used before.
We put these up for a commercial project and theyve been rock solid
585w n-type panels are next level. seeing better yield than we projected
Pallet transformed my suburban roofline. 21kW bifacial production monster.
Massive order but worth it. All panels tested good before deployment across three sites.
Heavy panels but quality is outstanding. Getting amazing production numbers.
Awesome value for commercial installs.
Very impressed with the consistency across the whole container
Great panels Solid output and super consistent every day

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.

  • 144 half-cut PERC cells
  • 550 W nameplate capacity
  • 21.28% efficiency
  • 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.
