Product Overview

The Jiangxi Risun Risun 330 330W polycrystalline solar panel is engineered for reliable day to day energy production in residential, commercial, and small industrial systems. This 330W polycrystalline module delivers a balanced mix of power, durability, and cost effectiveness while maintaining a compact footprint for tight roof spaces and ground mount arrays. With a panel efficiency of 16.6%, it converts sunlight into clean electricity with solid performance across real world conditions and diverse climates. The Risun 330 operates within a power range of 325 to 345 Wp, giving system designers flexible array sizing while staying within a proven product platform. Designed and manufactured by Jiangxi Risun Solar Energy Co., Ltd. in China, this module is backed by a 10 year product warranty and a 25 year performance warranty that limits total output degradation to 80% of the original power rating. Installers and system owners gain long term peace of mind along with a robust mechanical design that tolerates wide temperature swings and demanding on site environments.

Key Benefits

Stable 330W power output: The module delivers up to 330 Wp at standard test conditions, supporting strong system yields while keeping string design straightforward for common inverters.

Proven polycrystalline technology: Polycrystalline cells offer dependable performance and attractive pricing, making this panel a practical choice for budget conscious projects without sacrificing long term reliability.

Long term performance warranty: A 25 year power warranty limits degradation to 80% of the initial output, with an annual degradation rate of around 0.8% for consistent energy generation over decades.

Robust mechanical construction: Tempered glass, an anodized aluminium frame, and IP67 junction box protection provide strong resistance to moisture, dust, and mechanical stress in harsh environments.

Flexible system design: A maximum system voltage of 1500 V and a series fuse rating of 15 A allow longer strings and efficient BOS design in both rooftop and ground mount installations.

Wide operating temperature range: The panel operates from -40°C to 85°C with carefully specified temperature coefficients, supporting stable performance in hot, cold, and variable climates.

How It Works

The Risun 330 polycrystalline solar panel works by converting incoming sunlight directly into direct current electricity using 144 interconnected polycrystalline cells. Each cell absorbs photons from the sun and frees electrons inside its semiconductor structure, creating an electric current that flows through the module’s internal busbars and external cables. Under standard test conditions, this process delivers a maximum power output of 330 Wp at a voltage of 38.41 V and a current of 8.59 A. The open circuit voltage reaches 45.78 V, while the short circuit current is 9.03 A, allowing the module to perform effectively within a wide range of irradiance levels. Once installed in an array, multiple panels are wired in series and parallel strings to match the input window of a compatible inverter, which then converts the DC power into usable AC electricity. The tempered glass, robust frame, and IP67 junction box ensure the internal electrical components remain protected, so the energy conversion process continues reliably throughout the service life of the panel.

Photon absorption and DC generation: Sunlight strikes the polycrystalline cells and excites electrons within the silicon lattice, creating a potential difference across each cell. This potential difference forces electrons to flow in a single direction, producing direct current that becomes the base energy source for your system.

Module level power optimization: Within the panel, the 144 cells are arranged to deliver a stable maximum power point at 38.41 V and 8.59 A under standard conditions. This configuration helps maintain consistent output even when temperatures rise, thanks to defined temperature coefficients for power, voltage, and current.

System integration and safety: The module connects through 4 mm² DC cables to form strings compatible with 1500 V systems. A 15 A series fuse rating and an IP67 junction box support safe operation, while the anodized aluminium frame allows secure mounting that maintains optimal tilt and airflow.

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.
