This panel suits off-grid systems and small installations. High efficiency reaches 18.5 percent. Power output stays strong at 150 Wp. Degradation remains low over time. Total degradation rate is just 0.8 percent. Product warranty covers 10 years. Power warranty extends to 25 years at 80 percent. Swiss engineering ensures top quality. Panels fit residential and portable uses. They handle various conditions well. Power tolerance ranges from -3.5 to +3.5 percent. This model leads in compact solar solutions.

Key Benefits

High Efficiency: Panel achieves 18.5 percent efficiency. More power from less space results.

Long Warranty: 10-year product warranty protects investment. 25-year power warranty guarantees 80 percent output.

Low Degradation: 0.8 percent total degradation rate ensures longevity. Performance stays consistent for decades.

Swiss Quality: Made by 3S Swiss Solar Solutions AG. Precision manufacturing from Switzerland delivers reliability.

Versatile Use: Power range spans 120 to 200 Wp. Ideal for off-grid and portable solar setups.

How It Works

Sunlight hits the monocrystalline cells first. Electrons move to create current. PERC technology boosts light capture. This raises efficiency to 18.5 percent. Panels connect via MC4 connectors easily. Cables measure 1000 mm long. Systems handle up to 1000V safely. Temperature coefficients keep output stable. Low degradation maintains power over 25 years. Swiss design optimizes every aspect. Installation proves simple for most users. Output reaches 150 Wp reliably. This panel powers small homes and devices well.

Photon Absorption: Sunlight passes through glass cover. PERC cells absorb photons deeply. Electrons generate electricity efficiently.

Current Generation: Vmpp hits 16.6V at peak. Impp delivers 9A steadily. Open circuit reaches 20.3V maximum.

Thermal Management: Pmax coefficient is -0.371 percent per degree C. Voc adjusts at -0.276 percent per degree C. Performance remains stable in heat.

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.

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.
