Product Overview

The Balfar Solar 330W polycrystalline solar panel is designed as a reliable workhorse for residential, commercial, and industrial projects. Its 72-cell construction and 17% module efficiency provide a strong balance between output, durability, and price. This panel is built for long term performance, supported by a 10 year product warranty and a 25 year linear power warranty. After 25 years, at least 80.7% of the initial power is expected to remain available. With Brazilian manufacturing, robust anodized aluminium framing, and IP67 junction box protection, this module offers dependable performance in demanding outdoor environments.

At standard test conditions, the module delivers 330 Wp with a maximum power voltage of 37.91 V and current of 8.71 A. Under normal operating cell temperature, it still provides a strong 237.71 Wp output. These values make the panel well suited for grid tied inverters and DC system designs around 1000 V. The panel weight of 26 kg, combined with a 1956 x 992 x 40 mm frame, offers a familiar format for installers, making transport, racking design, and mounting straightforward on roofs or ground mounts.

Key Benefits

Balanced power and efficiency: The 330 Wp output and 17% module efficiency support strong generation from compact roof or ground areas. This balance helps designers hit project targets without oversizing structures or inverters.

Long term performance guarantee: Balfar Solar backs this module with a 10 year product warranty and 25 year linear power warranty. The guaranteed remaining output of 80.7% after 25 years gives confidence in long term energy yield.

Robust construction for harsh sites: The panel uses 3.2 mm high transparency solar glass and an anodized aluminium frame. An IP67 junction box and MC4 compatible connectors support safe operation in rain, dust, and high UV environments.

Installer friendly format: Standard 72 cell layout and 1956 x 992 mm dimensions integrate easily with common racking systems. The 26 kg weight remains manageable for two person handling during rooftop or ground mount installation.

Optimized electrical characteristics: A maximum system voltage of 1000 V DC and 15 A series fuse rating allow flexible string design. Tight positive power tolerance from 0% to +1.5% helps ensure that installed capacity meets or exceeds the nameplate rating.

How It Works

This polycrystalline solar panel converts sunlight into usable DC electricity through 72 interconnected silicon cells. Each 156 x 156 mm cell absorbs photons and releases electrons, creating direct current that flows through the panel wiring. Under standard test conditions, these cells work together to deliver up to 330 Wp of power. The energy then travels through MC4 compatible connectors and solar cables to an inverter or charge controller. There, the DC output is converted or regulated for homes, businesses, or battery storage. Thermal behaviour is carefully controlled, with defined temperature coefficients for power, voltage, and current. This data allows system designers to model performance accurately across a broad temperature range. The result is a stable, predictable energy source that supports reliable long term operation in on grid or off grid systems.

Energy capture in the cells: The 72 polycrystalline cells absorb sunlight and create electrical charge in each silicon wafer. These charges are driven by the internal electric field, forming current that moves through busbars and ribbons between cells.

Power generation and operating point: At the maximum power point, the panel operates around 37.91 V and 8.71 A under STC. In real world conditions, the operating point shifts with temperature and irradiance, but the module is engineered to maintain stable output.

Integration with the solar system: The panel connects in series and parallel strings to match inverter voltage and current windows. With a 1000 V system rating, designers can configure efficient string layouts while staying inside the 15 A series fuse limit.

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.
