LG vs Titan Solar Modules

Solar Panel Comparisons
LG vs. Titan solar panels product comparison

Solar panels are the key part of any solar installation. You can have the best inverter, a top-notch racking system, and the best battery backup that money can buy, but with below-par solar panels, you won’t be able to reap the benefits. To ensure that you get the best out of your solar installation, you need to make sure that you have the right panels for you.

Your situation determines which solar panels are necessary. For instance, some homes have roofs that are too small for a traditional solar installation, which would require premium solar panels to meet the energy needs of the home. Others may have ample unshaded space and can use a solar panel with a little less wattage and save some money. To ensure that we can service all types of homes, Go Solar Group stocks premium panels to go with our regular offerings.

We’ll be looking at two different solar panel types: LG and the Titan Solar panels produced by Silfab. Both options are part of Go Solar Group’s premium offerings. These solar panels offer higher efficiency ratings and wattages to ensure that you can get a full-sized system, even if you don’t have a lot of space. We have previously looked at LG solar panels and we will be continuing that theme today.

Comparing the Physical Components of LG and Titan Solar Panels

What makes premium solar panels premium is, mainly, their physical construction. In particular, there are two physical components of solar panels that will affect their total output: efficiency and wattage. Both of these will help determine how many solar panels a system needs and how much energy said system will produce.

Comparing the Efficiency Ratings of LG and Titan Solar

Efficiency refers to how much of the sunlight received by a solar panel can be converted into usable electricity. A panel with zero percent efficiency would convert no sunlight into energy. A panel with 100 percent efficiency would convert all sunlight into energy. 

Most polycrystalline solar panels have an efficiency rating of around 15 percent. Monocrystalline panels average around 19 percent, but can get up into the 20s with high-quality construction. Most residential solar installations will have panels with an 18-19 percent efficiency rating, which is more than enough for the average home. 

What Is the Efficiency of LG Solar Panels?

When it comes to efficiency ratings, LG is up there with the best. Their least efficient panels have about a 16 percent efficiency rating. However, their premium panels can get up into the 21 percent range. A 21 percent rating is well above average, perfect for homes that need to squeeze the most energy possible out of their panels.

What Is the Efficiency of Titan Solar Panels?

The Titan Solar panels are reported to have an efficiency rating of 20.2 percent. While that isn’t quite as efficient as the high end LG panels, it outstrips both LG’s less efficient panels and the average monocrystalline solar panel. The Titan Solar modules are a great fit for homes with less roof space.

While Titan Solar panels have a narrower range of efficiencies, they are less efficient that the highest quality LG panels. If you’re going for the absolute highest efficiency rating, then LG takes the day. However, Titan Solar is overall more reliable when it comes to an above average efficiency rating. 

Comparing the Wattages of LG and Titan Solar

The second main physical component of solar panels are their wattages. Sometimes called the power rating, a solar panel’s wattage refers to the amount of energy it produces in a single hour. A simple example: a 270 W solar panel will produce 270 watts of electricity in one sun hour. Your installation’s total power rating is going to be the combined wattages of each panel, which is how much the whole installation produces in one sun hour.

Having high wattages is useful for homes with smaller roofs. Most homes can go with more panels with slightly lower wattages, which tends to be more cost effective. Additionally, the more panels you have, the less likely you are to be impacted by any one panel degrading. However, some homes need to get as much electricity as possible out of limited space, in which case fewer panels with higher power ratings are necessary.

Polycrystalline solar panels cap out at 300 W. Monocrystalline panels have a wide range, starting at 300 W and averaging around 340 W. Some monocrystalline panels, however, can get much higher than that.

What Is the Watt Rating of LG Panels?

LG panels have premium power ratings, befitting their premium status. The lowest LG panels are around 320 W, but the high-end LG panels can get higher than 400 W — which is one of the highest power ratings possible. In fact, one of Go Solar Group’s premium LG options, the LG 435QAC-A6, has a power rating of 450 W. 

What is the Watt Rating of Titan Solar Panels?

Titan Solar has a watt rating of 370 W. This makes them above average when it comes to monocrystalline solar panels. While not reaching quite as high as the LG panels, a 370 W is a high-quality panel wattage and perfect for homes that need some extra juice from their panels. 

Solar Panel Life Cycle Comparisons

While the physical specs of solar panels are very important, the off-the-panel factors are also a big part of choosing the right panels for your home. A panel can have a high efficiency and good power rating, but without support from the panel manufacturer or your solar installer, you can lose out on very valuable energy production.

One of the biggest non-physical factors in the quality of solar panels are their warranties. Every solar panel degrades over time, like all electrical devices. Because they degrade, a longer warranty means more guaranteed power coming from your installation. There are two types of warranties: product warranties and production guarantees.

Comparing LG and Titan Solar Product Warranties Warranties

Product warranties are simple. They cover any form of manufacturer’s defect within your panels. Because solar panels have such a long lifespan — anywhere from 25 to 40 years — these defects sometimes won’t appear for many years. A longer product warranty means more protection.

What Is the Product Warranty for LG Panels?

While most solar panel manufacturers provide a 10-to-15-year warranty, LG stands a head above by providing a full 25-year warranty. This warranty will help catch almost any potential defects over your panel’s lifetime.

What Is the Product Warranty for Titan Solar Panels?

Titan Solar offers a 12-year warranty with all of its solar panels. This falls squarely into the average for monocrystalline solar panels. However, Titan Solar’s 12-year warranty can be expanded into a full 25-year warranty, putting it on par with LG.

Overall, while Titan Solar’s warranty starts at 12 years and LG’s at 25, they can both be equal to each other. However, the edge is given to LG.

Comparing LG and Titan Solar Production Guarantees

A production guarantee refers simply to the total power output of a panel over a period of years. Every solar panel degrades, but a solar production guarantee can help offset that by ensuring repairs or replacements can be done without cost to the homeowner.

For example, a solar panel with a production guarantee of 90 percent after 10 years means that your panels will be covered if they ever fall under that 90 percent production guarantee in the 10 year period. The higher a production guarantee is, and the longer it lasts, the better the guarantee is.

Note that the percentages listed are of the solar panel’s peak performance. So a 90 percent production guarantee means that it ensures that a solar panel provides 90 percent of it’s peak capacity.

What Is the LG Production Guarantee?

LG solar panel guarantees are a bit complicated. LG solar panels start off with a 95 percent guarantee after five years. Following this five year period, LG assumes that your panels will degrade at around 0.4 percent per year. The production warranty adjusts accordingly with each passing year. For example, in your sixth year, your production guarantee will be 94.6 percent. After 25 years, your guaranteed rate ends at 87 percent. 

What Is the Titan Solar Production Guarantee?

Titan Solar’s production guarantee is longer than LG’s. While LG stops after 25 years, Titan Solar’s warranty lasts for a full 30 years — a welcome sight. Titan Solar provides four benchmark years. 

  1. After the first year, your panels will produce at least 97.1 percent of their maximum.
  2. After 12 years, they will produce 91.6 percent. 
  3. After 25 years, they will produce 85.1 percent of the total power rating.
  4. At the end of the warranty, the end of the 30th year, your Titan Solar panels will produce at least 82.6 percent. 

While LG’s production guarantee has higher percentages overall, Titan Solar’s warranty lasts for an additional five years. This makes them difficult to compare, though we believe them to be about equal. After all, Titan Solar’s guarantee is only about two percent less than LG’s after 25 years.

So Which Is Better, LG or Titan Solar?

If we look at the physical characteristics, it becomes clear that LG’s higher quality solar panels are superior to Titan Solar’s panels. However, because LG has such a wide range of products, their low-end panels are worse than Titan Solar’s. When it comes to product warranties, LG’s product warranty is slightly better than Titan Solar’s, but their production guarantees are about equal, with Titan Solar’s possibly being a bit better because of the length of time it covers.

Ultimately, your choice of solar panels will depend on the specifics of your home. Both LG and Titan Solar have good panel options. Your home, needs, and financial situations will all play into which one you pick. However, LG stands out as a stellar choice for premium solar panels.
