How to choose the best solar panel | Sunkean.com

 Whether you're installing a DIY solar panel system or shopping for solar panels for your solar farm, you need to choose the best solar panels. A complete solar system includes batteries, inverters and solar panel arrays. Generally, the following criteria can be used to evaluate the quality of solar panels:

• Efficiency
• Warranty
• Durability
• Temperature coefficient

Efficiency

The efficiency rating of a solar panel refers to the amount of captured sunlight it can actually convert into useful energy. Remember that solar panels are only over 20% efficient at their best, and generally speaking, the most efficient solar panels will give you the most energy savings. For example, let's compare two 300-watt solar panels: one is 21% efficient and the other is 17% efficient. Under ideal conditions, both will produce 300 watts of power. However, the more efficient ones will be physically smaller and take up less space than the less efficient ones.

The main determinant of solar panel efficiency is the materials used in the panel. The most efficient material is single crystal silicon. But despite all the advantages, monocrystalline panels are generally the more expensive option.

Polycrystalline panels have a bluer tint and are generally less efficient than monocrystalline panels, meaning more panels are needed to generate the same amount of power. However, they are generally less expensive and may be a cheaper option despite requiring additional panels.

Durability

Solar panels represent a significant investment, and the durability of a solar panel is another indicator of its quality. If you want to choose a product that can be used for a long time. That means you need to buy solar panels that are durable and can withstand harsh weather.

Warranty

An important indicator of overall panel quality is a solid warranty from the manufacturer. Typically, solar panels come with a 25-year warranty, and of course, proper maintenance of solar panels to prolong their lifespan is also important.

Temperature Coefficient

Another important ranking factor is the temperature coefficient. For solar panels, the temperature coefficient refers to how much (or how much) the productivity of the panel decreases when the outside temperature increases. How solar panels work in extreme heat plays a key role in year-round power output.

SUNKEAN provides solar panels of various specifications, using high-quality raw materials, controlling from the source, and strictly testing to ensure that there is no hidden quality risk.

There’s no one-size-fits-all answer to which solar panels are the best. That answer changes based on a variety of factors, like your budget, how much electricity you’d like to generate, the space you have to install the system, and what aesthetic concerns you have.
