Product Overview

The Power Maxma 435 PERC Monocrystalline Solar Panel delivers a strong balance of power, efficiency, and durability for residential and commercial solar projects. With a rated output of 435 Wp and panel efficiency up to 19.7%, this module is engineered to extract more energy from every square meter of roof or ground space. Advanced PERC cell technology enhances low light response and boosts overall performance across a wide range of conditions.

This monocrystalline panel is designed for long term reliability, supported by a 10 year product warranty and a 25 year power warranty. The linear power guarantee is backed by a total degradation rate of 81.4% after 25 years, helping system owners plan predictable energy yields over time. With a maximum system voltage of 1500 V, it integrates easily into modern high voltage arrays and is suitable for both small and large installations.

A robust frame, IP68 junction box, and MC4 connectors support fast installation and reliable operation in demanding climates. The panel weight of 24 kg and dimensions of 2108 x 1048 x 40 mm offer a practical footprint for rooftops and ground mount systems. Built for the UAE market and international standards, the Power Maxma 435 PERC Monocrystalline Solar Panel provides a dependable choice for users who want stable long term solar performance.

Key Benefits

High power density for limited roof space: The 435 Wp output and up to 19.7% efficiency enable more energy from fewer panels. This helps maximize production where roof space is constrained or premium.

Advanced PERC monocrystalline technology: PERC cell architecture improves light capture and internal reflection, increasing energy yield throughout the day. Performance remains strong in hazy, early morning, and late afternoon conditions.

Long term reliability and warranties: A 10 year product warranty and 25 year power warranty support investment security. Controlled degradation with an 81.4% guaranteed output after 25 years helps secure predictable long term returns.

Stable performance in high temperatures: Temperature coefficients of -0.36%/°C for power and -0.28%/°C for voltage help limit losses in hot climates. This makes the panel well suited to regions with strong sun and elevated ambient temperatures.

Robust construction and secure connectivity: An IP68 junction box and proven MC4 connectors provide strong protection against dust and water ingress. The durable frame and 20 A series fuse rating support safe operation in modern arrays.

Versatile use across system sizes: The panel is suitable for residential, commercial, and light industrial projects in the UAE and beyond. Its electrical characteristics support flexible system design with a wide range of inverters.

How It Works

The Power Maxma 435 PERC Monocrystalline Solar Panel converts sunlight into usable DC electricity through high efficiency monocrystalline PERC cells. When sunlight hits the cells, photons are absorbed and generate electron flow, creating direct current power at the module output terminals. This DC power is then routed through MC4 connectors and cables to a compatible inverter, where it is converted into AC electricity for use in homes or businesses.

At its maximum power point, the panel delivers 435 Wp with a voltage of 40.8 V and a current of 10.67 A. The open circuit voltage of 49.4 V and short circuit current of 11.26 A define the operating window for safe string design. With a power tolerance of 0 to +1%, each panel is guaranteed to meet its nameplate rating or slightly exceed it. Over the lifetime of the system, the power output gradually decreases at a controlled rate, reaching a guaranteed 81.4% of initial power after 25 years.

The module operates within typical cell temperatures near 44.4 ± 2 °C under standard test conditions. Temperature coefficients describe how output changes as cell temperature rises or falls. This allows accurate energy modeling in different climates. The panel connects into arrays with maximum system voltage up to 1500 V, helping designers use longer strings and reduce balance of system costs when configured correctly.

PERC monocrystalline energy conversion: Each monocrystalline cell contains a PERC structure that reflects unabsorbed light back through the silicon. This second pass increases the chance of photon absorption and helps raise the module efficiency up to 19.7%. As a result, more of the available solar radiation is turned into electrical energy with each panel.

Operating at the maximum power point: During operation, the inverter tracks the voltage and current point where the panel produces its maximum power, known as Vmpp and Impp. For this module, that point is 40.8 V and 10.67 A, corresponding to 435 Wp. By continuously tracking this point, the system extracts the highest possible energy from changing sunlight conditions.

System integration and protection: The IP68 junction box houses bypass diodes and secure terminations that protect the panel in partial shade and adverse weather. Standard MC4 connectors ensure reliable plug and play integration with typical DC cabling. The 20 A series fuse rating and 1500 V maximum system voltage support safe string design when system engineering guidelines are followed.

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

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!
