Product Overview

The Jiacheng Solar JC-300-60M/MH 300W monocrystalline solar panel delivers reliable power and strong efficiency for modern installations. This high performance module is designed for residential, commercial, and small industrial projects that demand consistent output and long term value. With a rated power range from 300 to 320 watts, the panel helps maximise roof space and improve overall system yield. Its module efficiency from 18.44 to 19.67 percent supports higher energy production in limited mounting areas. A rugged anodized aluminium frame and tempered glass with anti reflection coating provide durable protection in harsh environments. The JC-300-60M/MH panel suits grid tied systems and off grid setups where dependable performance is required every day. Jiacheng Solar Technology Co., Ltd. manufactures this panel in China with strict quality control and proven monocrystalline cell technology. Installers and system owners can use this module as a versatile building block for efficient solar arrays.

Key Benefits

High power density: The 300 watt rated output allows more energy from a compact 1640x992 mm footprint. This helps maximise production on small or shaded roofs.

Strong module efficiency range: Panel efficiency between 18.44 and 19.67 percent supports higher kWh yield per square metre. This improves the overall system return on investment.

Reliable long term performance: A 12 year product warranty covers materials and workmanship. Linear power warranties guarantee 91.2 percent output at 10 years and 80.7 percent at 25 years.

Durable construction: Tempered glass with anti reflection coating and an anodized aluminium frame protect the cells. The panel is engineered for temperatures from minus 40 to 85 degrees Celsius.

Flexible system integration: A maximum system voltage of 1500 volts and a 20 amp series fuse rating support many inverter and mounting configurations. The panel suits both new builds and retrofit projects.

Easy handling and installation: The 18 kilogram module weight simplifies lifting and mounting on rooftops. Standard 60 cell layout and robust frame support common racking solutions.

How It Works

This monocrystalline solar panel converts sunlight into usable electrical energy through high quality silicon cells. Each of the 60 cells is manufactured from a single crystal structure, which promotes efficient charge movement. When sunlight hits the cell surface, photons transfer energy to electrons in the silicon lattice. These energised electrons create direct current that flows through the panel’s internal busbars and wiring. The module operates most efficiently around its rated maximum power voltage and current values. In a typical system, the panel connects in series or parallel strings to reach the desired array voltage and power. The generated direct current is then routed to an inverter or charge controller. There it is converted into alternating current for grid use or managed for battery storage. The JC-300-60M/MH module maintains stable performance across a broad temperature range, supported by defined temperature coefficients. Its robust glass, frame, and junction box protect electrical components so energy production continues reliably over decades.

Monocrystalline cell conversion: The 156.75 by 156.75 millimetre cells absorb solar radiation and free electrons inside the silicon structure. The electric field in each cell drives these electrons into the external circuit as direct current.

Operating at maximum power point: At standard test conditions, the panel reaches 300 watts at 32.6 volts and 9.21 amps. System inverters track this maximum power point to optimise energy harvest during changing sunlight and temperature conditions.

System integration and protection: The module connects into strings that feed a 1500 volt rated system with proper overcurrent protection. The 20 amp series fuse rating and strong junction box design help protect wiring and downstream components during operation.

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.
