Product Overview

The Intelbras EMSC 330P 330W polycrystalline 72-cell solar panel is designed for reliable energy generation in residential, commercial, and rural projects of any size. With a maximum power output of 330 Wp and module efficiency of 17%, this panel delivers a strong balance between performance and affordability for grid-tied and off-grid systems. Each module is individually tested by Intelbras to ensure consistent quality and secure long-term operation in demanding outdoor environments. A robust anodized aluminium frame, IP67 junction box, and MC4-compatible connectors help simplify installation and enhance durability on rooftops or ground-mounted arrays. The panel is engineered to operate from -40°C to 85°C, making it suitable for diverse climates found across Brazil and other global markets. Backed by a 25-year linear power warranty, the Intelbras EMSC 330P offers dependable output, with at least 80% of nominal performance expected after 25 years of operation. This makes it an attractive solution for installers and system owners seeking bankable, long-lasting photovoltaic modules.

Key Benefits

Excellent cost-benefit for diverse projects: The EMSC 330P module offers attractive energy yields at a competitive cost, supporting projects from small homes to large commercial systems while maintaining Intelbras quality standards.

High 330 Wp output with 17% efficiency: The 330 Wp nominal power and 17% efficiency help maximize energy generation per square meter, optimising available roof or ground space in constrained installations.

Proven durability with IP67 protection: An IP67-rated junction box, anodized aluminium frame, and robust encapsulation protect the 72 polycrystalline cells against dust, humidity, and heavy rain in outdoor conditions.

Reliable performance across wide temperatures: The panel operates from -40°C to +85°C, with optimized temperature coefficients that help maintain power output under high heat and changing weather conditions.

Long-term energy security with 25-year warranty: A 25-year linear performance warranty, with at least 80% of nominal power after 25 years, supports long-term project bankability and investment returns.

How It Works

The Intelbras EMSC 330P solar panel converts sunlight into usable electrical energy through its 72 polycrystalline silicon cells. When sunlight hits the cells, direct current is generated and delivered through factory-installed cables and MC4-compatible connectors to your inverter or charge controller. Under standard test conditions, the module produces up to 330 Wp at a maximum power voltage of 37.15 V and current of 8.89 A, making it suitable for a wide range of string configurations. In real-world operation, performance is influenced by factors such as irradiance, temperature, mounting angle, and shading, which are mitigated through careful system design. The panel is engineered to perform efficiently both at standard test conditions and at nominal operating cell temperature, with a Pmax of 230.4 W under NOCT, helping deliver stable energy production throughout the day. Its temperature coefficients limit performance losses in hot climates, while the rugged construction and IP67 junction box ensure stable operation over decades of field exposure.

Photovoltaic energy conversion: The 72 polycrystalline cells are interconnected to form a high-performance DC generator that responds instantly to sunlight. When photons strike the silicon cells, an electric field is created, releasing electrons and generating direct current electricity that flows through the panel’s internal busbars to the output cables.

Power delivery under standard and NOCT conditions: At standard test conditions, the panel delivers its rated 330 Wp with a voltage at maximum power of 37.15 V and current of 8.89 A, enabling flexible series connections for 1500 V systems. Under nominal operating cell temperature, output stabilizes at 230.4 W with 33.92 V and 6.79 A, reflecting typical field performance under real-world irradiance and temperature levels.

System integration and protection: The factory-mounted junction box with three bypass diodes helps reduce power loss caused by partial shading and improves string reliability. MC4-compatible connectors and 4 mm² cables support secure, low-loss connections to inverters, while the 1500 V maximum system voltage and 15 A series fuse rating allow the module to integrate seamlessly into modern high-voltage arrays.

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.

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

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!
