What`s the Best Solar Panel

Determining what`s the best solar panels can be challenging, especially with the proliferation of solar companies over recent years.In this article, we present the most important considerations to evaluate the quality of solar panels and share recent findings from third-party review sites.

Evaluation criteria

You can use several criteria to evaluate the quality of solar panels:


Efficiency refers to the amount of power produced at peak daylight as sunlight is absorbed. For example, if a solar panel is rated at 20% efficiency, then 20% of the sun’s energy that hits the panel will convert to solar energy to use for power electricity. 

Xinpuguang@_Rigid Series-Monocrystalline module is constructed with high-performance monocrystalline solar cells, which have a conversion efficiency of more than 21% under sunny weather conditions. It provides a long service life and is virtually maintenance-free. Using tempered glass, EVA film with excellent weather resistance and TPT backplane, and a high-quality aluminum frame. Outdoor service life is guaranteed, up to more than 25 years.


The expected lifetime of equipment and the length of time a company will guarantee its performance are correlated. Here are three considerations to keep in mind when evaluating a solar manufacturer’s warranty:

Equipment: Ask about the warranty coverage for performance and materials. Make sure you understand if there are different guarantees on the inverter, monitoring, and other equipment in addition to the panels.

Process: Ask about the warranty services provided. Be sure to understand the required steps to file a claim and assess whether the company will make it easy for you to replace, repair, or get reimbursed for any defective parts.

Longevity: A warranty is only as good as the issuing company’s reputation. If your solar company goes out of business before the end of the term, you could be left without coverage. Make sure you’re confident that the manufacturer will be around for the duration of your warranty period.



A solar panel’s durability is another indicator of its quality. Several reputable third-party organizations independently test solar panels. Their ratings will give you an idea of how well yours will hold up in harsh conditions such as storms, hurricanes, hail, and more over time. 


Aesthetics are very important for some buyers, although they’re considered a “soft” measure of quality for the most part. The current appearance trend for solar panels  leans toward less visible, including black backing (also referred to as black-on-black panels). Coming years will likely see various styles of solar roof tiles.


Solar panel quality also relates to a manufacturer’s commitment to responsibility in their products, operations, and impact on other stakeholders. The best solar panels have a minimal impact on the environment during the manufacturing process as well as at the end of their lifestyle.
