Module Efficiency
72 Cells
N-Type TOPCon

Product Overview

The Amso Solar AS330-72 330W polycrystalline solar panel delivers reliable performance for on-grid and off-grid systems. This robust module offers a nominal power rating of 330 W, with panel efficiency up to 17 percent. It suits residential rooftops, light commercial projects, small agricultural sites, and off-grid charging systems. A 72 cell layout supports stable energy production, even under warm operating conditions. The panel is engineered for 1500 V systems, which helps reduce overall balance-of-system costs. With a durable anodized aluminium frame and tempered glass, long service life is supported in varied climates. Designed and manufactured by Amso Solar Technology Co., Ltd. in China, it sits within a broader product range from 310 to 340 W. Installers and system designers can standardize around this format for flexible array planning.

Key Benefits

Balanced power and efficiency: With 330 W output and 17 percent efficiency, this panel offers strong energy yield in a familiar 72 cell format. It suits users seeking dependable performance without premium pricing.

Wide operating temperature range: The module operates from minus 40 to 85 degrees Celsius, supporting installations in cold and hot regions. Stable temperature coefficients help maintain predictable performance as temperatures rise.

Durable construction for harsh sites: Tempered glass with 3.2 millimetre thickness and an anodized aluminium frame protect the cells. The IP68 junction box improves resistance to moisture and dust on rooftops and ground mounts.

Flexible system design: A maximum system voltage of 1500 volts allows longer strings and fewer parallel connections. This flexibility helps reduce cabling costs and simplifies array layout on larger projects.

Proven safety and integration: The panel supports a 15 amp series fuse rating and uses MC4 connectors for straightforward wiring. Compatibility with leading inverters and mounting systems is made easier by this standard format.

How It Works

The Amso Solar AS330-72 panel converts sunlight into usable electrical power through its 72 polycrystalline solar cells. When sunlight reaches the tempered glass surface, photons pass through and strike the semiconductor material inside each cell. This energy frees electrons and creates direct current, which flows through internal busbars and external connectors. System wiring routes the current into a charge controller or grid tied inverter, depending on the system type. The inverter then converts the direct current into alternating current suitable for household appliances or grid export. Throughout this process, temperature coefficients and electrical parameters determine how much power is delivered under real outdoor conditions.

Light capture and DC generation: The 72 polycrystalline cells are arranged to maximize exposure to sunlight across the module face. As sunlight hits each cell, a direct current is generated at a voltage defined by the cell string. The combined array of cells produces a maximum power of 330 watts under standard test conditions.

Operating at maximum power point: The panel delivers its highest output near 37.4 volts and 8.83 amps, known as the maximum power point. A modern inverter or charge controller tracks this point dynamically to optimize production as light and temperature change.

Protection, wiring, and system integration: An IP68 junction box houses bypass diodes and connection points, helping maintain performance under partial shading. Standard MC4 connectors provide secure, quick connections between modules and system cabling. The 1500 volt system rating allows multiple panels in series while staying within safety limits.

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

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.
