Monocrystalline Cells

Product Overview

The 1st Sunergy S-205C solar panel delivers reliable power for residential and small commercial applications. This high-performance module features 72 monocrystalline cells arranged in a robust half-cell design. The bifacial technology captures sunlight on both sides, increasing total energy yield significantly. Its compact 205-watt output suits limited roof spaces while maintaining efficiency. The frame includes curved hook reinforcement, boosting mechanical load strength by 10%. Current grading effectively avoids 2% power loss caused by current mismatch during installation. This ensures maximum output power under varying light conditions. The panel withstands harsh environments with anti-PID, salt mist, and corrosion resistance. It meets IEC 61701 and IEC 62716 standards for durability. Operating temperatures range safely from -40°C to +85°C. This makes it ideal for diverse climates worldwide. The 1500V system voltage supports modern high-voltage inverters. Its sleek design blends functionality with aesthetic appeal for any home.

Key Benefits

Bifacial Energy Capture: Captures sunlight on both front and rear sides to increase total energy yield by up to 25% in optimal conditions.

Enhanced Mechanical Strength: The C-side frame features curved hook reinforcement, enhancing mechanical load strength by 10% for superior durability.

Reduced Power Mismatch Loss: Advanced current grading effectively avoids 2% power loss caused by current mismatch during installation, achieving max output power.

Extreme Environmental Durability: Withstands 90% additional environmental tests including anti-PID, salt mist, and corrosion resistance for long-term reliability.

Wide Temperature Range Operation: Operates safely in temperatures from -40°C to +85°C, making it suitable for diverse climates worldwide.

How It Works

The 1st Sunergy S-205C solar panel converts sunlight into electricity through the photovoltaic effect using monocrystalline silicon cells. When photons strike the cell surface, they excite electrons, creating a flow of direct current. The bifacial design allows light to enter from both the front and rear, maximizing energy generation. This dual-sided capture significantly boosts efficiency compared to traditional single-sided panels. The half-cell construction reduces internal resistance and minimizes heat loss during operation. Current grading ensures each cell operates at its peak potential, preventing mismatch losses. The robust frame protects the internal components from wind, snow, and physical stress. This system works seamlessly with modern inverters to power homes and businesses efficiently.

Photovoltaic Conversion: Sunlight photons strike monocrystalline silicon cells, exciting electrons to generate direct current electricity. This process is the core of solar energy production.

Bifacial Light Absorption: Light enters through both the front glass and the rear transparent layer, capturing reflected sunlight for increased total yield. This dual-sided approach maximizes efficiency.

Current Grading Optimization: Precise classification of cells avoids 2% power loss from current mismatch during installation. This ensures every cell contributes to maximum output power.

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.

Jacob B

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

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Brian H

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

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!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
