When navigating the solar market, you may hear the expression “Tier 1 solar panels”. So, what exactly is a Tier 1 solar panel? Simply put, it is an expression that describes the quality or standard of the solar panel.
Let’s take a closer look at Tier 1 solar panels, and what differentiates them from Tier 2 or Tier 3 panels.
What is the difference between Tier 1, Tier 2 and Tier 3 solar panels?
Solar panels should ideally last for at least 25 years, but the expected lifespan may vary from product to product. The manufacturer’s warranty will usually tell you what to expect. But it is also important that the manufacturer actually honour the warranty.
In addition to this, it is advised to consider the effectiveness of the solar panel system. How big is the expected power output?
This is where the solar panel classification is relevant. You will find both Tier 1, Tier 2 and Tier 3 solar panels, and in most cases, it is advisable to buy the first – both when it comes to warranty and effectiveness. The lower the classification, the better the product.
Tier 1 solar panels are considered high standard
A Tier 1 solar panel is usually built with a very high standard, and the manufacturer will typically have a great reputation in the solar market. The high standard will make Tier 1 panels a safe choice, but it is not necessarily the right choice for you.
Why choose a Tier 1 solar panel?
There are several reasons to invest in Tier 1 solar panels if your budget allows you to do so. The high quality standard is usually associated with a longer lifespan, and you may expect the Tier 1 panels to last longer than Tier 2 or 3 panels.
Within the solar power industry, the manufacturers of Tier 1 solar panels are also known to have a highly regarded reputation. Because of this, you may also expect the service to be excellent.
The Tier 1 solar manufacturers will in most honour the warranty, and give you a new product if problems arise.
Are there any downsides to Tier 1 solar panels?
Although Tier 1 solar panels are considered the best, they are also the most expensive. In many cases, they will cost 30% more than other solar panels. So, if your budget is limited, the Tier 1 panels might be out of reach.
At the same time, the quality will make the panels last longer. Therefore, it may not be the most expensive option in the long run.
What to expect from Tier 1 solar panels?
A Tier 1 solar panel is usually built with quality materials, including top-grade silicone. And as you might already know; the better the silicon grade, the better the performance of the solar panel will be.
The production methods are also considered to be very high-tech. Usually, the panels are produced by advanced robots, which will eliminate or minimize typical errors.
The manufacturers also invest in research, to make sure they are delivering the best possible technology on the market. Here is what to expect from Tier 1 manufacturers:
- Top grade construction and materials
- Great performance
- The newest technology
- Product warranty: 12 years +
- Performance warranty: 25 years +
- Expensive
Canadian Solar, SunPower, Jinko Solar, LONGi, JA Solar and Trina Solar are all considered to be Tier 1 solar panel manufacturers.
What to expect from Tier 2 solar panels?
Tier 2 panels are considered to be of “good quality”, but not as good as Tier 1 panels. The panels are typically produced by both robots and humans. Here is what you should expect if you buy a Tier 2 solar panel system:
- Good quality with moderate-grade materials
- A certain chance of human errors
- Somewhat lower performance
- Medium price level
- Good warranties (but often shorter than Tier 1 warranties)
When it comes to manufacturers in the Tier 2 category, we can mention both Axitec Solar, RenewSys Solar and Luxor Solar.
What to expect from Tier 3 solar panels?
You will also find Tier 3 solar panels. The manufacturers will in most cases be assemblers, and they do not build all the parts themselves. In other words, they assemble solar cell technology from other manufacturers and use these to construct solar panels.
The solar panels will often be built manually, and not by robots. This can affect the quality of the panels, which will depend on the skillset of the operator. Lovsun Solar, Tanfon Solar and Dongsun Solar are all considered Tier 3.
- Lowest quality
- A certain chance of human errors
- The least expensive choice
Choose the right solar system for you
When buying a solar panel system, you can choose between Tier 1, Tier 2 and Tier 3 solar panels. Although Tier 1 is the best choice quality- and warranty-wise, it is also the most expensive.
Find the solar panel that is right for you and your budget.
