Product Overview

The Amso Solar AS3420-72 320W polycrystalline solar panel is engineered for dependable performance in demanding environments. This 72-cell module balances power, efficiency, and cost, making it suitable for commercial rooftops, ground mounts, and off-grid systems. The module delivers a maximum power output of 320 Wp with a panel efficiency of 16.5 percent. A robust anodized aluminium frame and 3.2 mm tempered glass help protect the cells in harsh weather. The panel operates within a wide temperature range from minus 40 to 85 degrees Celsius. A 12 year product warranty supports long term reliability and value.

Designed by Amso Solar Technology Co., Ltd. in China, the AS3420-72 series covers a power range from 310 to 340 Wp. The 1500 volt system rating enables longer strings and reduced balance of system costs. Stable performance is supported by carefully controlled temperature coefficients for power, voltage, and current. MC4 compatible connectors and an IP68 rated junction box help simplify installation and ensure secure electrical connections. This panel offers a reliable foundation for medium and large scale solar projects that require proven polycrystalline technology.

Key Benefits

Reliable 320W Power Class: The module delivers up to 320 Wp of rated power under standard test conditions. This output supports higher system yields across commercial and industrial installations.

Balanced Efficiency and Cost: Panel efficiency of 16.5 percent provides solid energy density without excessive cost. This balance suits budget sensitive projects that still demand dependable generation.

Durable Construction: The 3.2 mm tempered glass and anodized aluminium frame improve mechanical strength. Resistance to wind, snow, and handling stress is enhanced for long term use.

Wide Operating Temperature Range: The panel operates from minus 40 to 85 degrees Celsius. This capability makes it suitable for hot deserts, cold climates, and changing seasonal conditions.

High System Voltage Compatibility: Support for 1500 volt systems allows longer strings and fewer parallel connections. This can reduce cabling, combiner boxes, and total installation costs.

Secure IP68 Junction Box: The IP68 rated junction box protects electrical connections from dust and water ingress. Long term reliability in outdoor environments is improved as a result.

How It Works

The Amso Solar AS3420-72 320W polycrystalline solar panel converts sunlight into usable direct current electricity. Seventy two polycrystalline cells are wired together inside a sealed laminate. When sunlight hits the cells, photons transfer energy to electrons within the semiconductor material. This process creates a flow of electric current which exits through the MC4 connectors. The generated DC power is then routed to an inverter or charge controller, depending on system design. The inverter converts the DC power to AC power for onsite use or grid export.

Voltage and current at maximum power are carefully defined for predictable performance. The panel reaches a maximum power of 320 Wp at approximately 36.8 volts and 8.7 amps. Open circuit voltage is 45.8 volts, while short circuit current is 9.19 amps. System designers can use these values to size string lengths and inverters safely. The temperature coefficients indicate how output changes as cell temperature rises. This information helps model annual energy production in different climates.

Photovoltaic Energy Conversion: Polycrystalline silicon cells absorb incoming sunlight and free charged particles inside the crystal structure. An internal electric field directs these electrons, causing them to move as DC current. This current is collected by the cell busbars and combined across the 72 cells in series strings.

Power Output and System Integration: At maximum power point, the module delivers about 36.8 volts and 8.7 amps. Strings of panels are connected in series until the desired DC voltage window for the inverter is reached. The inverter then converts this DC input into AC electricity for loads or grid supply.

Thermal Management and Performance: Real world power varies with cell temperature, as described by the temperature coefficient of Pmax at minus 0.4 percent per degree Celsius. As temperature rises, output slowly decreases, which is included in system yield estimates. The wide operating temperature range ensures safe function in both very cold and very hot conditions.

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.
