N-Type TOPCon

Product Overview

The Waaree Bi-55-520 520W Bifacial Mono PERC Solar Panel is designed for projects that demand high output and reliable performance. This dual glass module uses advanced monocrystalline PERC cells and bifacial technology to capture light from both sides. Energy yields are increased without needing extra roof or ground space. The panel delivers a strong 520 Wp nominal power rating at standard test conditions with 20.20% module efficiency. It fits neatly into commercial, industrial, and large residential arrays. The robust dual glass construction improves durability in harsh environments. With a 12 year product warranty and extended power guarantee, long term energy production is supported. The Waaree Bi-55-520 panel helps lower levelized cost of energy while maintaining strong performance over decades.

Key Benefits

High power density per module: Each panel delivers 520 Wp of rated power, allowing powerful arrays with fewer modules. System design can stay compact while still meeting ambitious energy targets.

Bifacial energy gains: Light is harvested from both front and rear sides for higher specific yield. Backside gain potential up to 30% can be achieved with reflective surfaces and optimized mounting.

Durable dual glass construction: The framed dual glass design protects cells from moisture and mechanical stress. Long term reliability is enhanced compared to traditional backsheet modules.

Optimized for modern systems: The 1500 V system voltage and 25 A series fuse rating suit utility and commercial designs. Compatibility with standard MC4 type connectors simplifies integration.

Long lasting performance warranty: A 12 year product warranty is combined with a 30 year power output guarantee. Output is warranted at 91.95% in year 12 and 82.05% by year 30.

How It Works

This Waaree Bi-55-520 module converts sunlight into usable DC power using high efficiency mono PERC cells. Light strikes the 182 mm monocrystalline cells on the front glass and generates an electric current. At the same time, diffuse and reflected light reaches the rear glass surface and adds extra power through bifacial gain. The half cut cell layout reduces resistive losses and improves shade tolerance. Current from all cells is collected within the split junction box and delivered through MC4 compatible connectors. A suitable inverter then converts the DC power into AC electricity for on site use or grid export.

Bifacial dual glass light capture: The module uses 2.0 mm low iron glass on both sides to allow light entry. The front side captures direct irradiance, while the rear side collects reflected light from the ground or roof. This design can raise effective module efficiency significantly in well designed installations. Rear side gains between 15% and 30% are achievable depending on surface albedo and mounting height.

Half cut mono PERC cell architecture: The 144 half cut cells are arranged in a 12x6 plus 12x6 layout for improved performance. Each full cell is divided to lower operating current and reduce resistive losses. The PERC structure enhances light trapping and boosts conversion efficiency. This design also improves shade tolerance because the module behaves like two parallel strings.

Thermal and electrical optimization: The module is engineered with favorable temperature coefficients for hot climates. Power loss is limited to around -0.35% per degree Celsius above STC cell temperature. Voltage and current behavior is predictable across changing conditions, simplifying string design. The 1500 V maximum system voltage allows longer strings and reduced balance of system costs.

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.
