Max Power Output

20.94%

Module Efficiency

156 Cells

Monocrystalline

Product Overview

The ESG New Energy ES-585W is a high-output monocrystalline solar panel built for dependable energy generation. It delivers strong performance with 585 Wp maximum power and 20.94% panel efficiency. Its positive power tolerance of 0 to +1% supports consistent output. The module uses 156 cells and a robust 182×182 mm cell format. It is designed for projects that need reliable power, stable operation, and efficient use of space. The panel also supports demanding electrical environments with a 1500V maximum system voltage. Its durable construction and anti-reflection tempered glass help improve light capture and long-term reliability.

Key Benefits

High power output: The module provides 585 Wp, making it suitable for strong energy production targets.

Efficient space use: At 20.94% efficiency, the panel supports more generation from the available roof or ground area.

Positive tolerance: The 0 to +1% power tolerance helps ensure output is not below the rated value.

Durable construction: Tempered anti-reflection glass, PET materials, and an anodized aluminium frame support long service life.

Broad installation suitability: The 1500V system voltage and 25A fuse rating support modern utility, commercial, and large-scale systems.

How It Works

The ES-585W converts sunlight into usable electricity through monocrystalline photovoltaic cells. Light enters the module through anti-reflection coated tempered glass, which helps reduce surface reflection. That allows more sunlight to reach the cells. The cells then generate direct current electricity, which is collected and routed through the junction box. Three bypass diodes help maintain performance during partial shading and reduce power loss. The panel is built to operate across a wide temperature range, so it remains suitable for many climates and installation conditions.

Light capture: The anti-reflection tempered glass improves sunlight transmission. This helps the cells absorb more available light.

Power generation: The monocrystalline cells convert sunlight into electrical current. The module reaches 44.41V at maximum power and 13.18A current.

Protection and flow control: The junction box uses three diodes to reduce losses under shading. This helps preserve output and system stability.

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.
