6 November, 2023 The DeepBlue 4.0 Pro modules build upon the legacy and strengths of the DeepBlue series. They excel in power generation, characterized by minimized degradation, enhanced high-temperature energy yield, increased bifacial generation benefits, and outstanding performance under low irradiance conditions. Compared to p-type modules, the BOS cost of DeepBlue 4.0 Pro modules can be reduced by approximately 2%-4.5%, leading to a decrease in LCOE by around 2.5%-6%. With the warm responses from the global market, JA Solar started to supply the module in Q3 2023.
