Product Overview

The Maxray Solar Panels 140W 12V module is a compact, high‑efficiency monocrystalline panel designed for reliable off‑grid power. With a rated output of 140 watts at 16 volts, it suits 12V battery charging in caravans, camper trailers, boats, tiny homes, and remote sites across Australia. A panel efficiency of 16.8% helps you harvest more energy from limited roof or deck space. The module uses quality tempered glass and an anodized aluminium frame for long‑term durability in harsh outdoor conditions. Stable performance is supported by tight power tolerance from -3% to +3%. This 140W 12V solar panel offers a dependable balance of size, weight, and output for mobile and fixed off‑grid systems.

Key Benefits

Optimised for 12V systems: The 16V operating voltage is ideal for 12V battery charging using PWM or MPPT controllers. This makes integration into existing off‑grid power systems simple and efficient.

High monocrystalline efficiency: Panel efficiency of 16.8% extracts more power from every square metre. This supports applications with restricted mounting space, such as vehicle roofs or compact cabins.

Durable outdoor construction: Tempered glass and an anodized aluminium frame protect cells from impact and corrosion. The design suits demanding Australian climates, from coastal regions to inland heat.

Wide operating temperature range: The module operates from -40°C to 85°C for consistent output in varied weather. This range supports performance during cold mornings and hot summer afternoons.

Reliable performance tolerance: A power tolerance of -3% to +3% provides predictable energy yield. This gives installers and system owners confidence in planning daily production and autonomy.

How It Works

The Maxray 140W 12V monocrystalline solar panel converts sunlight into DC electricity using high‑efficiency silicon cells. When exposed to light, the cells generate a voltage, producing a maximum power output of 140W under standard test conditions. The panel typically operates around 16V at maximum power, which suits 12V battery banks via a compatible charge controller. Current flows from the panel through solar cabling into your regulator and storage system. The open circuit voltage of 20V and short circuit current of 9.33A define safe design limits. In regular operation, the panel delivers up to 8.75A at maximum power to support lighting, refrigeration, pumps, and electronics in off‑grid installations.

Sunlight to DC power generation: Individual monocrystalline cells absorb sunlight and release electrons, creating DC current. The cells are wired in series and parallel within the module to reach the 16V operating point and 140W output rating.

Battery charging through a controller: The produced DC power is routed to a solar charge controller connected to your 12V batteries. The controller regulates voltage and current, preventing overcharge and ensuring safe, efficient energy storage.

System integration and protection: The panel operates within a maximum system voltage of 1000V, supporting series wiring in larger arrays. Proper fusing, cabling, and mounting hardware help protect the installation and maintain long‑term performance in the field.

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.

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.
