The Znshine Solar ZXM7-SHLDD144-540/M is a high-performance monocrystalline solar panel, engineered for efficiency with advanced technological features such as bifacial technology, allowing for additional energy capture. Designed to withstand various weather conditions gracefully, this panel promises substantial power output even after extensive use. Perfect for installations in both residential and commercial settings, it assures users of durability and reliability.
Incorporating cutting-edge cell efficiency, the Znshine Solar ZXM7-SHLDD144-540/M reduces the gap between bus bars and grid lines, enhancing power output efficiently.
The panel delivers impressive power even under low-light conditions, such as during overcast weather or in the early morning, maximizing energy yield throughout the day.
With the use of Anti PID technology, power degradation due to potential induced degradation is minimized, ensuring consistent performance over time.
Built to endure high wind pressures up to 2400 Pa and heavy snow loads of 5400 Pa, this panel is extremely resistant to harsh weather scenarios.
Znshine provides a remarkable 30-year power output warranty, assuring that the panels will maintain at least 80% of their initial power output, reflecting stellar long-term value.
The Znshine Solar ZXM7-SHLDD144-540/M operates by capturing sunlight with its advanced monocrystalline cells, enhancing energy yield by leveraging bifacial design to harness solar energy from both sides of the module. This ensures efficient electricity production day in and day out.
This feature plays a crucial role in improving the efficiency of the solar module by allowing more light absorption and efficient energy conversion, pivotal for optimal performance.
With half-cell designs, the panel reduces power loss, improves shading tolerance, and boosts performance even under partial shading conditions.
Maximizes power generation with its innovative bifacial design, capturing solar energy from both the front and the rear of the panel for higher overall yield.

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.

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.

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!

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.

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.

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!

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.
