LG vs. Qcells: Which Solar Panel is Better?
In the competitive solar market, choosing the most appropriate solar panels for your home or business can be overwhelming. LG and Qcells are two of the leading giants that always offer cutting-edge technology and high-performance solar products with strong warranties. But which one really stands out for your specific requirements and energy goals?
Regardless of whether you value longevity, energy generation, or cost-effective solutions, comparing LG and Qcells is essential to make a wise investment.
LG and Qcells Comparison
To help you find the best solar panels, we will compare LG and Qcells. The comparison will be based on some important factors that must be pondered while choosing a solar brand.
Cost Differentiation:
In the meantime, when you consider different brands, the solar panel cost is always a notable element. It plays an important role in a purchase decision. Many solar panel brands are available in the market. There are top-of-the-line solar panels that ensure the best performance. However, they also cost more. Also, there are middle-line options that are a combination of good performance and affordable prices.
If we compare LG solar panels with Qcells, LG is more expensive. This is because the company has positioned itself in the market as a premium brand. It manufactures solar panel systems of the highest efficiency and top quality. But these high-performance panels also cost more. In comparison, Qcells solar panels are a more affordable option. These solar panels are also efficient and perform well. Although they are not as high in performance as LG panels, you can still save well with them. So, if the cost matters to you, Qcells panels will be the best choice to go solar with. However, if performance and efficiency matter, the LG solar panels will be a worthy investment.
Efficiency Rating:
The solar panel efficiency is the percentage of solar output. Higher efficiency reflects the greater power-generating ability of panels during a specific time. According to the solar market, the solar efficiency of LG panels is 15%-23%. It is considered to be the most efficient panel provider. Its highest-performance solar panel has an efficiency of 21.7%. The least efficient module is 19.6% efficient.
On the other hand, the efficiency range of Qcells is 18.6%-20.6%. Although they are not at the same level of efficiency as LG, they are still a good option at an affordable price. You can go with Q. PEAK DUO panels if you require an efficiency level of around 20%. These are half-cut solar panels and have 120 or 144 cells instead of 60 or 72 cells as standard solar panels. Such types of solar cells are considered more efficient and durable. But they are somehow more expensive.
Product Warranty :
Product warranty is an important element. It ensures your investment protection in case of any product or material defect. The leading solar panels brands always offer extensive and long-lasting warranties to increase their customer satisfaction. Also, they trust their brand and products. While comparing the warranties of LG and Qcells, it is analyzed that both brands offer 25-year product warranty. The customer can replace or repair the defective panels during the product warranty times for both brands. Moreover, the LG solar warranty not only includes the material cost but also bears the labor cost. Generally, very few companies offer such warranties to their customers. Also, both companies are trustworthy. Customers can expect that they will stand by their warranties. LG is not only a solar industry leader but also behind the success of LG Electronics as well. LG Electronics is considered a technology giant globally.
Panel Performance Warranty & Degradation Rate:
Solar companies also offer performance warranties for their solar energy panels. This performance warranty sets the standard for the panel degradation rate. The panel degradation rate refers to the decrease in the solar panel’s production rate over time. It means that the amount of solar energy produced by the panels decreases every year. The solar performance warranty ensures that the solar panels will not degrade so quickly. It satisfies the customer that the panels will produce power for a long period. With a performance warranty, the companies assure you that the panels will not degrade more than a specific degradation rate. If it varies, the companies are responsible for replacing the solar panels.
The Qcells solar can generate 98% output after the initial year. The degradation rate is 0.54%. The efficiency ratio will be 93% during the 10 years, and after 25 years, the panels will remain 85% efficient. Conversely, the solar degradation rate of LG panels is less than Qcells. These solar panels will generate 98% after the first installation year. Then they will be at 0.33% degradation, and after 25 years, they still can generate 90.08% power from solar energy panels.
So, according to the performance warranty, we can observe that LG is better in 25 years by remaining 90% efficient as compared to Qcells. But when it comes to affordability, Qcells performance is also good.
LG vs. Qcells: Which is right for you?
Both solar brands, LG & Qcells, offer high-quality and efficient solar panels for your solar energy system. If Qcells is an affordable option, LG panels are more efficient. However, choosing between the two brands depends upon one’s priority. If your budget is limited and you want to go solar at a reasonable price, Qcells is the best option. But, if you have limited roof space or you are a business owner, you may require high-performance, premium-quality products for maximizing output, you should choose LG solar panels.
In conclusion, these two solar brands are quite competitive and if you limit your choices to just two brands, you can’t go wrong in either case. Both brands will lead you to maximize solar savings and output throughout their lifespan.
