Polycrystalline

Product Overview

The Amso Solar AS340-72 340W polycrystalline solar panel is engineered for reliable energy production in residential, commercial, and small industrial systems. With a maximum power output of 340 Wp and panel efficiency up to 17.5%, it delivers strong performance while keeping system costs under control. Its 72-cell polycrystalline architecture offers a solid balance between efficiency, durability, and value for money. The module operates safely up to 1500 V system voltage, which supports flexible string design and longer arrays. A robust anodized aluminium frame, tempered glass, and IP68 junction box help protect the module in demanding outdoor environments. With a 12-year product warranty and a proven power range from 310 Wp to 340 Wp, this panel is well suited to long-term grid-tied or off-grid solar projects.

Key Benefits

Balanced power and efficiency: The module provides up to 340 Wp with 17.5% efficiency, supporting compact system designs on roofs and ground mounts.

Proven 72-cell format: A classic 72-cell layout offers stable output and is widely compatible with modern string inverters and charge controllers.

Rugged construction: Tempered glass, a 3.2 mm front pane, and an anodized aluminium frame provide mechanical strength and long-term durability outdoors.

Enhanced electrical safety: An IP68-rated junction box and MC4 connectors help ensure secure wiring, strong insulation, and reliable performance in wet conditions.

Wide operating temperature range: The panel operates from -40°C to 85°C, with controlled temperature coefficients that support stable power output in different climates.

Dependable warranty coverage: A 12-year product warranty from Amso Solar Technology Co., Ltd. supports long-term investment confidence.

How It Works

The Amso Solar AS340-72 polycrystalline module converts sunlight into direct current electricity using its 72 interconnected solar cells. When sunlight hits the polycrystalline cells, photons are absorbed and free electrons are released, creating an electric current. This current flows through the cell busbars, then through the module’s internal wiring into the IP68 junction box. From there, MC4 connectors link the panel to the rest of the solar array and system components. In a typical installation, multiple modules are connected in series and parallel to achieve the desired DC voltage and current. The DC power then feeds a solar inverter or charge controller, which converts it to usable AC power or controlled DC for batteries. Temperature coefficients and operating limits help keep output predictable in real-world conditions.

Energy generation through 72 polycrystalline cells: The module uses 72 polycrystalline silicon cells that are connected in series to reach the rated voltage. Each cell contributes a portion of the overall power, and together they deliver 340 Wp under standard test conditions. The polycrystalline structure helps maintain robust performance while controlling production costs, which benefits system economics.

Voltage and current behavior under load: At its maximum power point, the module operates around 37.7 V and 9.02 A. Open circuit voltage is 46.5 V, while short circuit current is 9.5 A, providing a clear design window for string sizing. Temperature coefficients of -0.4%/°C for Pmax and -0.29%/°C for Voc describe how output changes as cell temperature rises, helping designers estimate yield in hot or cold environments.

System integration and protection: The 1500 V maximum system voltage allows longer strings, which can reduce cable runs and balance-of-system costs. A 15 A series fuse rating helps protect the module from overcurrent events in large arrays. The IP68 junction box shields internal connections from dust and water, while MC4 connectors provide a secure, standardized interface for cabling. Combined with the aluminium frame and tempered glass, these elements create a robust module ready for rooftop or ground-mounted systems.

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.
