Product Overview

The SolarSpace SS8-72HD-545M solar panel delivers reliable 545W output with high module efficiency for demanding projects. This mono PERC module uses 144 half-cut M10 cells to maximize performance and reduce resistive losses. The design suits commercial rooftops, ground mounts, and utility-scale arrays where every watt matters. Its maximum efficiency reaches about 21.10 percent under standard conditions. A 1500V system rating allows longer strings and lower balance-of-system costs. Power tolerance from 0 to +3 percent ensures installed capacity meets expectations or exceeds them. A robust aluminum frame, coated glass, and IP-rated junction box support long-term outdoor durability. The SS8-72HD-545M offers a strong combination of power, efficiency, and reliability for modern solar installations.

Key Benefits

High Power Density: Each module delivers up to 545W, so fewer panels are required per system. Rooftops and ground mounts can achieve higher capacity within limited space.

Efficient Mono PERC Cells: Advanced mono PERC M10 cells improve light capture and conversion efficiency. Half-cut architecture lowers electrical losses and enhances real-world energy yield.

Stable Long-Term Performance: A low temperature coefficient of Pmax helps maintain output on hot days. Controlled degradation rates support dependable production across the full service life.

Robust Mechanical Design: An anodized aluminum frame and tempered coated glass protect the cells from harsh conditions. The panel is engineered for structural rigidity and long-term outdoor use.

Flexible System Integration: A 1500V DC system voltage rating allows long string design on commercial and utility projects. Compatibility with modern inverters and racking simplifies engineering and installation.

How It Works

The SolarSpace SS8-72HD-545M solar panel converts sunlight into usable DC electricity using high-efficiency mono PERC cells. When light strikes the 144 half-cut M10 cells, photons are absorbed and free electrons are created. These electrons move through the cell structure and busbars, forming an electric current. Half-cell design reduces resistive losses, so more of the captured energy becomes power at the terminals. The module is optimized around a maximum power voltage of about 41.81 volts under standard test conditions. When wired into strings, panels feed a compatible inverter that converts DC power into AC power. This AC energy can be consumed on-site or exported to the grid, depending on system design and interconnection rules.

Mono PERC Cell Conversion: Each monocrystalline PERC cell uses a passivated rear surface to reflect unabsorbed light back through the silicon. This process gives photons a second chance to be converted into electricity, improving cell efficiency. The uniform crystal structure of mono silicon further supports higher performance and better low-light behavior.

Half-Cut Layout and Current Flow: The 144 half-cut cells are arranged in strings that operate at lower current and higher voltage. Lower current reduces resistive losses across conductors and busbars, which raises overall power output. This layout also increases tolerance to partial shading compared to full-cell formats.

Thermal and Electrical Stability: The SS8-72HD-545M is designed with stable temperature coefficients for voltage and power. As cell temperature rises, output voltage drops, but optimized coefficients help limit these losses. Within the operating range from -40 to 85 degrees Celsius, the panel maintains predictable performance and safe operation.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!
