How long does a LONGi Solar panel last?

With the increased stability of Gallium-doped silicon, LONGi is able to reduce the LID effects over the first year to 2% and less than 0.5% per year for the remaining life of the panel resulting in the panel retaining close to 85% of the original power rating after an increased 30 year period.

Do LONGi Solar panels degrade?

LONGi’s latest Hi-MO 6 (Scientist) series guarantees that their solar panels will degrade no more than 1% in the first year and then no more than 0.4% for the following 24 years. This gives them a slight edge of many of their competitors who typically offer (2.5% in year 1 and 0.7% thereafter).

How many solar panels does Longi produce a year?

Their annual production capacity is reported to be 105GW for silicon wafers and 60GW for solar panels Q2 2022. LONGi owns most steps in the vertical supply chain to produce a solar panel including producing ingots, silicon wafers and solar cells.

How long do solar panels last?

Most reputable manufacturers offer production warranties for 25 years or more. The average break even point for solar panel energy savings occurs six to 10 years after installation. If the panels continue to produce at a high level for another 15 years after that, you will end up saving thousands of dollars during the solar panels’ lifespan.

Are LONGi Solar panels good value based?

Longi Solar offers value based solar panels that come with high efficiency standards, and above average 25 year performance output. In comparison to other value based panels, they come below the average price point with similar efficiency ratings. The same is true when Longi's modules are compared to mid-range panels.

Does LONGi Solar have a warranty?

Longi solar panels come with an industry standard warranty of 10 year product and 25 year linear performance. This period is matched by Trina Solar, Canadian Solar and other value-based/mid range competitors. The product warranty is less than LG and Panasonic, which come with 25 year product and performance warranties.
