Product Overview

The HD Solar HD-66HPH-410M polycrystalline solar panel delivers reliable 405–425 Wp performance with high conversion efficiency. Designed for residential, commercial, and light industrial rooftops, this module balances strong output with durable construction. Its compact 1924x1038 mm footprint and 22 kg weight simplify transport and on-roof handling for installers. A panel efficiency of up to 21.3 percent helps maximize energy generation from limited roof space. The module operates safely on systems up to 1500 V, supporting modern high-voltage string designs. Robust anodized aluminium framing, tempered glass, and IP68 junction box protection enhance long-term reliability. The HD-66HPH-410M is supplied by Jiangsu Hongde Technology Development Co., Ltd. in China, offering consistent manufacturing quality. With a tight 0 to +3 percent power tolerance, each panel is guaranteed to deliver at least its rated output. This combination of efficiency, stability, and mechanical strength makes it a dependable choice for cost-conscious solar projects.

Key Benefits

High power density for limited roof space: With a power range from 405 to 425 Wp, this panel extracts more energy per square meter, helping systems reach target kWh production on tight rooftops.

Consistent output with positive power tolerance: A 0 to +3 percent power tolerance ensures each module meets or exceeds its nameplate rating, supporting predictable array sizing and yield calculations.

Robust performance in real-world temperatures: Optimized temperature coefficients for power, voltage, and current help maintain strong production as module temperature rises under sun exposure.

Durable construction for long service life: Tempered glass, anodized aluminium frame, and IP68 junction box protection support dependable operation across harsh outdoor environments and weather conditions.

Installer-friendly format and wiring: The 22 kg weight, standard 1200 mm cables, and 4 mm² cable cross section simplify handling, mounting, and electrical connections for installation teams.

How It Works

The HD-66HPH-410M solar panel converts sunlight into usable electrical energy through its 132 polycrystalline cells. When sunlight reaches the cell surface, photons transfer energy to electrons in the silicon structure. This energy movement generates direct current, which flows through the module’s internal busbars and conductors. The generated current is collected in the junction box, then delivered through the 4 mm² DC cables to the system inverter. The inverter converts the direct current into alternating current suitable for household or commercial loads. During operation, the open circuit voltage and short circuit current define the module’s behavior in each string. The specified NOCT temperature and thermal coefficients help predict output under real operating conditions rather than test conditions. When combined in series and parallel strings, multiple modules form an array that powers buildings or charges batteries. All components work together to deliver stable energy production throughout the system’s lifetime.

Polycrystalline cell energy conversion: Each of the 132 polycrystalline cells is engineered to absorb sunlight and create an internal electric field. The field drives charge carriers towards the panel conductors, producing a continuous direct current output under irradiation.

Power delivery through optimized voltage and current: At maximum power, the module operates around 38 V and 10.79 A, delivering stable 410 Wp under standard test conditions. These parameters support efficient string design, allowing installers to match panel strings with inverter input windows.

System integration with inverters and protection: The 1500 V maximum system voltage enables longer strings, which can reduce cabling and balance-of-system costs. Built-in bypass diodes inside the IP68 junction box help manage shading by limiting power losses and protecting cells from localized heating.

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.

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.
