580 Wp

Max Power Output

20.76%

Module Efficiency

156 Cells

Monocrystalline

Product Overview

The ESG New Energy ES-580W is a high-output monocrystalline solar panel built for strong energy generation and dependable long-term use. It delivers a rated power of 580 Wp, making it suitable for demanding residential, commercial, and utility-scale projects. The module uses 156 cells and reaches an efficiency of 20.76 percent. Its power tolerance of 0 to +1 percent supports consistent output. The panel is designed for stable performance across a wide operating range. It also includes an anti-reflection tempered glass surface for improved durability and light capture. With a 10-year warranty, it offers practical value for modern solar installations.

Key Benefits

High Power Output: The module provides 580 Wp for strong system performance.

Reliable Efficiency: Its 20.76 percent panel efficiency supports effective solar energy conversion.

Precise Power Control: A 0 to +1 percent power tolerance helps maintain consistent module output.

Durable Construction: Tempered anti-reflection glass and anodized aluminium improve protection and longevity.

Flexible Installation: A 1500 V maximum system voltage supports modern array designs.

Compact Engineering: The 35 mm frame and 32 kg weight support practical handling and installation.

How It Works

The ESG New Energy ES-580W converts sunlight into usable electricity through monocrystalline solar cells. Incoming light is absorbed by the cell surface and transformed into direct current power. The module is engineered to support stable voltage and current output under real-world operating conditions. Its anti-reflection glass helps reduce light loss and improves energy capture. The tempered glass layer also adds mechanical strength for outdoor use. Heat, voltage, and current performance remain controlled through carefully defined electrical limits. This makes the panel suitable for solar systems that require dependable daily generation and long service life.

Sunlight Conversion: The monocrystalline cells capture sunlight and convert it into electrical energy. This process begins as photons strike the cell surface and generate current.

Surface Optimization: Anti-reflection tempered glass reduces visual and optical losses. More light reaches the active cell area, which supports better output.

System Integration: The module operates within defined voltage and current ranges. This helps it connect smoothly within a larger solar array.

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.
