450 Wp
Max Power Output
20.4%
Module Efficiency
PERC
N-Type TOPCon

Product Overview

The Power Maxma 450 PERC Monocrystalline Solar Panel delivers reliable 450 Wp output for homes and businesses in the UAE and beyond. This high efficiency module uses advanced monocrystalline PERC cell technology to maximise power generation from limited roof space. With panel efficiency of up to 20.4 percent, more energy is produced from every square meter installed. A robust IP68 junction box and MC4 connectors support hassle free integration into new and existing systems. The module is designed for 1500 volt systems, enabling flexible string design for commercial scale or residential arrays. A 10 year product warranty and 25 year power warranty support long term investment confidence. Even after 25 years of operation, at least 81.4 percent of the initial power output is maintained under the stated warranty. This versatile module is well suited for grid tied rooftop projects, small commercial plants, and off grid systems when paired with suitable inverters and batteries. At 24 kilograms, the panel combines sturdy construction with manageable handling during transport and installation. Power Maxma supplies this panel from the UAE, helping regional projects benefit from dependable performance in demanding climates.

Key Benefits

High power density for tighter roofs: The 450 Wp rating and up to 20.4 percent efficiency help deliver strong output from compact roof areas. System designers can achieve target yields with fewer modules.

Stable long term performance: A 25 year power warranty with 81.4 percent guaranteed output supports predictable energy production. Degradation is limited to an average of 0.74 percent per year under the stated warranty terms.

Efficient PERC monocrystalline cells: Passivated emitter and rear cell technology enhances light capture and boosts real world energy yield. Monocrystalline construction promotes higher efficiency and consistent quality.

Robust electrical design: With 41.4 volt Vmpp and 10.88 amp Impp, arrays can be configured efficiently across a range of inverters. A maximum system voltage of 1500 volts offers flexibility for longer strings.

Installation ready and durable: A rugged 2108 by 1048 by 40 millimetre frame provides strength with convenient handling. IP68 junction box protection and MC4 connectors simplify wiring and improve reliability in harsh environments.

Optimised for hot climates: A Pmax temperature coefficient of minus 0.36 percent per degree Celsius supports better performance in high temperatures. This behaviour is ideal for installations across the UAE and other warm regions.

How It Works

The Power Maxma 450 PERC Monocrystalline Solar Panel converts sunlight into DC electricity using high efficiency crystalline cells. When sunlight hits the front surface, photons are absorbed within the silicon cell structure and release electrons. These electrons are directed by the internal electric field inside each cell, creating a usable current. Individual cells are factory interconnected in series and parallel strings to achieve the required voltage and current levels. The assembled module then delivers DC power through the integrated junction box and MC4 connectors. This DC output is typically routed to an inverter, where it is converted into AC electricity for household or commercial loads. Surplus energy can be exported to the grid or stored in batteries, depending on the system design and local regulations. Throughout this process, the tempered glass, encapsulant, and backsheet protect the cells from weather and mechanical stress. The module maintains performance within defined temperature limits by using selected materials and controlled thermal coefficients. In real installations, mounting structures hold the panels at an optimised tilt and orientation to maximise annual energy yield.

Light capture with PERC cell design: PERC technology adds a passivated rear surface that reflects unabsorbed light back into the cell. This design increases the chance of photon absorption and improves efficiency under real world conditions.

DC power generation and output: Within the module, cells are interconnected to reach 41.4 volt Vmpp and 10.88 amp Impp. The resulting 450 Wp output is delivered through the IP68 junction box and MC4 connectors to downstream equipment.

Thermal behaviour and climate resilience: The module operates around a nominal temperature of 44.4 degrees Celsius plus or minus two degrees. Thermal coefficients for Pmax, Voc, and Isc help predict performance as cell temperatures change throughout the day.

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.

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.
