Product Overview

The SolarSpace SS8-54HSB-420M mono PERC solar panel delivers 420 watts of high efficiency power for modern rooftop systems. This all black module combines sleek aesthetics with advanced cell technology for reliable long term energy production. With 108 half cut monocrystalline PERC cells, it is engineered to perform strongly in real world conditions. The module efficiency reaches up to 21.51 percent, which helps maximize output from compact roof areas. A 12 year product warranty and 25 year linear power warranty support dependable operation over decades. Gallium doped wafers and optimized circuitry reduce annual degradation and improve performance under partial shading. The panel uses robust tempered glass, a black anodized aluminium frame, and an IP68 junction box for harsh weather resistance. This SolarSpace SS8-54HSB-420M 420W Mono PERC Solar Panel is well suited for residential rooftops and small commercial arrays. It offers a refined all black finish that blends cleanly with modern architecture while delivering strong energy yields. Installers gain a balanced combination of power density, reliability, and visual appeal in one compact module.

Key Benefits

High power in a compact footprint: The module delivers up to 420 watts with 21.51 percent efficiency, enabling more energy from limited roof space.

All black premium aesthetics: The uniform black cells, frame, and backsheet create a clean appearance that enhances modern homes and visible arrays.

Reliable long term performance: Gallium doped wafers and advanced half cell design reduce light induced degradation and improve durability over time.

Strong output in real conditions: Optimized circuitry and PERC cell technology support higher yields under mixed weather, lower irradiance, and partial shading.

Robust construction and safety: Tempered glass, an anodized aluminium frame, 1500V system rating, and IP68 junction box help ensure safety and structural reliability.

How It Works

This SolarSpace mono PERC panel converts sunlight into usable DC power through high efficiency monocrystalline cells. Each of the 108 half cut PERC cells captures solar energy and transforms it into electrical current with reduced internal losses. The cells are wired in an optimized circuit layout that supports higher power density and better behavior under shade. Generated DC power flows through the low resistance busbars into the junction box and then out via MC4 compatible connectors. From there, the current is directed to a compatible inverter, which converts the DC electricity into AC power for onsite consumption. Surplus energy can be exported to the grid or stored in batteries, depending on system design and local regulations. The module’s robust materials and sealed IP68 junction box protect the internal electronics from moisture and dust ingress. Temperature coefficients are optimized so output remains more stable as cell temperatures rise during hot weather. In everyday operation, this design helps deliver consistent generation and strong energy yields across varied climates. The result is a dependable rooftop panel that quietly produces clean electricity throughout its long service life.

Mono PERC cell conversion: Monocrystalline PERC cells capture incoming sunlight and reflect previously unused photons back into the cell layer. This process improves electron generation, boosts efficiency, and allows more energy from each square meter of panel area.

Half cut layout and circuitry: Each cell is split into two smaller units, which reduces resistive losses and lowers internal heating. This configuration also improves behavior under partial shading, because only part of the string is affected while the rest continues to produce power.

System integration and protection: Power from the module passes through an IP68 rated junction box with three bypass diodes that help limit hot spots during shading. MC4 compatible connectors simplify series and parallel wiring to inverters or optimizers, supporting safe and flexible array design.

Customer Success Stories

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!
