Product Overview

The Energy America EA 340W bifacial polycrystalline PERC solar panel is engineered for reliable long term performance in residential, commercial, and small utility projects. This high output module delivers up to 340 Wp of front side power with panel efficiency up to 17.14 percent, allowing strong production even where roof or ground space is limited. Bifacial PERC cell technology captures light from both the front and rear surfaces, which can increase total energy yield over the life of the system. A robust 30 year product warranty is combined with a long term performance guarantee that maintains 97.5 percent output in year one and 83 percent after 30 years of operation. The EA 340W panel uses 144 half cut polycrystalline cells, low iron tempered glass with anti reflection coating, and an IP68 rated junction box to support dependable output in harsh outdoor environments. With a maximum system voltage of 1500 V, flexible power range from 335 to 360 Wp, and versatile mounting options, this module is a practical choice for cost effective, high durability solar installations across the United States.

Key Benefits

High power density for tight spaces: Up to 340 Wp output with module efficiencies up to 18.15 percent enables more energy generation on constrained roofs and compact ground mounts.

Bifacial energy gain: Bifacial PERC technology captures reflected light from the rear side, increasing total kWh production on bright surfaces such as light colored roofs, concrete, gravel, or snow.

Long term durability: A 30 year product warranty and optimized degradation rate of about 0.57 percent per year help protect your long horizon energy investment and reduce replacement risk.

Reliable performance in tough climates: The operating temperature range from minus 40 to 85 degrees Celsius, combined with stable temperature coefficients, supports consistent performance in hot and cold locations.

Robust construction and protection: Anti reflection tempered glass, an IP68 junction box with three bypass diodes, and a 1500 V system rating enable secure integration with modern inverters and racking systems.

Flexible system design: The wide power range from 335 to 360 Wp and low positive power tolerance from zero to plus three percent allow tailored string designs for diverse project requirements.

How It Works

The EA 340W solar panel converts sunlight into usable electrical power through advanced bifacial PERC polycrystalline cells. Each of the 144 half cut cells is designed to capture direct light on the front side and reflected light on the rear side, increasing overall energy harvest during each day. When the panel is exposed to sunlight, photons strike the cell surfaces and free electrons, creating direct current electricity at the module terminals. This DC power is then routed through the integrated junction box and cables to your inverter, which converts it into alternating current usable by household or commercial loads. Temperature coefficients are optimized so output remains predictable as cell temperature changes, while anti reflection tempered glass and durable encapsulation materials protect the electrical components from weather and mechanical stress. Over time, the panel is designed to degrade slowly, retaining 97.5 percent of its initial output in the first year and about 83 percent after three decades of operation under standard conditions.

Bifacial PERC energy capture: The bifacial design allows both sides of the module to participate in energy generation. Front side cells absorb direct sunlight while the rear surface collects light that bounces off the roof, ground, or nearby structures, increasing daily yield without additional footprint.

Half cut polycrystalline cell layout: The 144 half cell configuration reduces resistive losses and minimizes the impact of partial shading on module performance. This layout helps maintain higher string efficiency, because currents are lower within each cell path and shaded sections affect a smaller portion of total output.

Thermal and electrical stability: Temperature coefficients for power, voltage, and current are carefully balanced to stabilize energy production in varying weather. Even as the module heats during midday sun, performance loss remains moderate, while the high system voltage rating supports longer strings with compatible inverters.

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

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.

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!
