Yingli 135W photovoltaic panel

How efficient are Yingli solar panels?

Yingli Solar panels have efficiency ratings between 19.08% and 20.70% which are high-efficiency ratings. When determining a solar panel's power rating, solar panels are tested under standard test conditions, or conditions that remain constant to fairly compare and test solar panels.

What types of solar panels does Yingli Solar offer?

Yingli Solar now offers only monocrystalline, half-cell solar panels. In the past, the company provided full, polycrystalline modules. Here’s an overview of the panels Yingli Solar offers:

Who makes Yingli solar panels?

Yingli Solar is one of the oldest renewable energy manufacturers and has been in business since 1998. The Yingli business model covers the entire production process of the panel. From the raw materials that make silicon solar cells, or ingots, to the backsheets, Yingli strives to ensure that each solar panel is high-quality.

How temperature-tolerant are Yingli solar panels?

Yingli solar panels have temperature coefficients of -0.34 to -0.37 %/*°C. While this is decent, most modern solar modules have temperature coefficients between 0.3 and 0.7 %/*°C. However, as a vertically integrated company, Yingli manufactures everything from ingots and wafers to cells and modules, allowing it to have better control over product quality.

Are Yingli solar panels bifacial?

Yingli's mono series panels are monocrystalline, half-cell panels commonly used for residential solar systems. However, the mono GG series panels have bifacial construction, meaning they can generate power from both sides.

Do Yingli solar panels have a warranty?

• The warranty for Yingli Solar panels is nothing but standard: 12 years for the product and 25 years for performance. Bifacial panels get a 30-year output warranty. • During the years of Yingli Solar's decline, some customers reported having trouble with getting warranty support.
