LG Versus AEG Polycrystalline Module Comparison

Solar Panel Comparisons
LG vs. AEG Polycrystalline Module

Adding solar to your home is no light matter. Taking the time to compare brands and products will help you make the best decision for your project.

Each of our product comparisons looks at factors worth considering when comparing solar products and services. In this product comparison, Go Solar Group’s selection of LG solar panels goes against the AEG polycrystalline Module.

Solar Panel Types and Why it Matters

The first thing to consider when comparing solar panels is the materials used. Monocrystalline and Polycrystalline are the two main solar cell types on the market right now.

Different materials yield different efficiencies per solar panel. Two solar panels with the same wattage rating may vary in size because of the efficiencies, which makes a big difference when working with limited space.

Polycrystalline AEG Module

AEG has several monocrystalline solar panels options. However, this comparison delves into the AEG polycrystalline solar panel line, also known as the AEG Professional Series. Polycrystalline modules have improved significantly over the years, making them a more economical option for homeowners with amble unshaded space.

LG Monocrystalline Solar Panels

Go Solar Group uses LG solar panels with monocrystalline cells. Monocrystalline solar panels cost more. However, it’s the only way to acquire the system size necessary if you have limited unshaded space.

Luckily there is a range of efficiencies and wattages within monocrystalline solar panels, making them more affordable and customizable to the needs and financial constraints of the customer. There are three different 370 watt LG solar panel options that Go Solar Group uses. Each of these solar panels offers varying efficiencies, which equates to different panel sizes and pricing.

Module Efficiencies, Wattage and Size Between Brands

While the wattage and size are important for measuring a solar panel’s capacity, its efficiency is largely a byproduct of its composition and solar cell power.

LG Solar Panel Specs

Go Solar Group uses four different LG solar panels. These modules include LG370A1C-V5, LG370N1K-A6, LG370N1K-E6, and LG435QAC-A6.


The LG370A1C-V5 is a 370-watt monocrystalline solar panel with 21.4 percent module conversion efficiency. The dimensions of this solar panel come to 66.9 x 40 x 1.5 inches.


The LG370N1K-A6 produces 370 watts with monocrystalline solar cells. However, its module conversion efficiency is 20.4 percent, meaning it also has larger dimensions at 69.6 x 41 x 1.5 inches.


The LG370N1K-E6 is another 370-watt monocrystalline solar panel. However, its efficiency is 20.1 percent, and its dimensions are 69.6 x 41 x 1.5 inches. Because this solar panel’s efficiency is only slightly lower, its dimensions are the same as the LG3701K-A6, meaning the difference between these two solar panels comes down to price and availability.


The last Go Solar Group offered LG solar panel is the LG435QAC-A6. This monocrystalline module produces 435 watts. It has an efficiency rating of 21.9 percent and dimensions of 75.1 x 41 x 1.5 inches.

This solar panel not only produces more electricity, but it’s also taller. With the extra six inches of height, this solar panel produces 65 more watts per solar panel, making it ideal for homes with limited space or homeowners who don’t want their solar array to take up their entire roof.

Specifications of AEG Solar Panel

AEG has two polycrystalline solar panel lines within the AEG Professional Series. These solar modules include the AS-P608 and the AS-P728.


AS-P608 solar panels will produce between 270-280 watts. Additionally, their efficiencies range between 16.6 and 17.2 percent. Each solar panel takes up 64.57 x 38.97 x 1.37 inches.

While this solar panel is smaller than all the LG options listed above, it also produces between 100 and 90 watts less electricity per solar panel than the selection of LG 370-watt modules. A solar array with these AEG modules will require more solar panels and space for the same power production.


The AS-P728 solar panels yield between 320 and 335 watts, with efficiency ratings ranging from 16.8 to 17.3 percent. The solar panel measurements come to 77 x39 x 1.37 inches.

These solar panels are two inches taller than the LG 435-watt solar panel, and they produce between 115 – 100 watts less. As you can see from these specs, this solar panel requires infinitely more space for the same sized system as all the LG solar panel options offered by Go Solar Group.

Solar Panel Warranty Overview

Solar Panel Warranties are a must to consider. While solar panels don’t have moving parts, which simplifies maintaining them, they can break or malfunction. However, a quality solar panel warranty will take care of underlying problems that cause abnormal solar panel efficiencies over the life of the warranty.

LG Solar Panel Warranties

The LG solar panels listed above use one of two different warranties. These warranties include the Standard LG Warranty and the NeON® R Series Warranty.

Standard LG Warranty

The Standard LG Warranty covers 98.5 percent of original performance the first year and 90.6 percent the remainder of the 25-year warranty. It has a promised degradation rate of no more than 0.33 percent annually after the first year.

NeON® R Series Warranty

The NeON® R Series Warranty offers 92.5 percent of original production over a 25-year warranty. Among the Go Solar Group LG selection, this warranty covers LG370A 1C-V5 and LG435QAC-A6.

AEG Solar Panel Warranty

AEG offers a 12-year product warranty and a 25-year linear performance warranty for AEG Professional Series solar panels. This warranty covers 97 percent of nominal power output in the first year. The remainder of the 25-year warranty guarantees 80.2 percent with a 0.7 percent annual degradation rate.

These modules deliver less from the start and degrade faster, meaning that while they may last for 25 years, they will produce significantly less than the LG solar panels and most other monocrystalline solar panels.

Deciding on a Solar Panel Brand

Depending on the project, the efficiency, wattage, and size differences may be non-issues. Each interested individual needs to assess their project requirements and priorities before deciding which solar panel will best meet their needs.

Someone with a vast amount of unshaded space in a moderate climate may find that the polycrystalline solar panel that AEG offers works for them. However, those with limited space will want a solar panel that combines a higher wattage with a higher efficiency rating. Those in climates that switch between extreme temperatures would do better with a monocrystalline solar panel.
