HTL Solar HTL-72HP-405M Monocrystalline 144-Half-Cell Mono Solar Panel

HTL-72HP-405M | Monocrystalline | 144 Half-Cell | Mono | 1500V System Voltage

405 Wp

Max Power Output

22.4 %

Module Efficiency

Half-Cell Count

Product Overview

The HTL Solar HTL-72HP-405M Monocrystalline 144-Half-Cell Mono Solar Panel delivers exceptional energy performance for commercial and residential projects. This high-efficiency module generates 405 Wp of power with a remarkable 22.4% efficiency rating. Its advanced monocrystalline technology ensures consistent output under various light conditions. The 144 half-cell design reduces internal resistance and minimizes hot-spot risks. Built with tempered glass and an anodized aluminum frame, it withstands harsh weather. The panel offers a 30-year power warranty with only 0.57% annual degradation. This robust solution is ideal for maximizing space efficiency in solar installations.

Key Benefits

High Power Output: Generates 405 Wp of maximum power for superior energy generation in limited spaces.

Exceptional Efficiency: Achieves 22.4% module efficiency, converting more sunlight into usable electricity than standard panels.

Half-Cell Technology: The 144 half-cell layout reduces internal resistance and improves shade tolerance significantly.

Long-Term Warranty: Includes a 30-year power warranty with only 0.57% annual degradation for lasting reliability.

Robust Durability: Features tempered glass and an anodized aluminum frame to withstand extreme wind and snow loads.

How It Works

The HTL Solar HTL-72HP-405M Monocrystalline 144-Half-Cell Mono Solar Panel converts sunlight into electricity through the photovoltaic effect. When photons strike the monocrystalline silicon cells, they excite electrons to create a flow of direct current. The half-cell configuration splits standard cells into two, reducing electrical resistance and heat generation. This design allows the panel to maintain higher efficiency even when partially shaded or in low-light conditions. The tempered glass protects the cells while allowing maximum light transmission. The aluminum frame ensures structural integrity against environmental stress. The junction box safely collects and outputs the generated power to your system.

Photovoltaic Conversion: Sunlight photons hit monocrystalline cells, exciting electrons to generate direct current electricity. This process creates a continuous flow of energy from sunlight.

Half-Cell Optimization: Splitting 144 cells into half-cells reduces internal resistance and minimizes power losses. This improves performance under partial shading conditions.

Power Collection: The junction box collects generated current from all cells and outputs it safely. The IP67 rating protects internal components from dust and water.

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.

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.
