Ja solar energy storage test

Why did JA Solar and TÜV Rheinland conduct a one-year energy yield test?

JA Solar and TÜV Rheinland recently reported the results of a one-year energy yield test at the national outdoor yield test base for PV products in Qionghai, Hainan, China. The test aimed to study and verify the power generation performance of different types of modules, especially n-type modules and p-type modules. 1. Project Information

What is the energy yield performance of JA Solar n-type and PERC modules?

In the full-year test period, the energy yield performance of JA Solar n-type modules and the PERC modules are shown in Figure 2. The average daily energy yield of these two modules was 5.03 kWh/kW and 4.84 kWh/kW respectively, with n-type modules surpassing the PERC modules by about 3.9%.

Does JA Solar have a warranty?

Regarding power degradation, due to the natural advantage of n-type modules for LID-free and better LeTID performance versus p-type modules, JA Solar provides a 30-year linear power output warranty with less than 1% degradation in the first year and less than 0.4% annual degradation in the following years.

How many hours a year does a solar system last?

The company conducted the tests between February 2021 and February 2022. The results were confirmed by Germany's TÜV Nord. The testing location has an annual average temperature of 8 C and an annual average solar radiation of 2,800 to 3,000 hours with a solar spectrum very close to the standard illumination conditions (AM1.5).
