After briefly reviewing the BOM optimization across different environmental scenarios, Liuzza discussed the company’s latest specialized application modules: offshore, anti-dust, and anti-glare modules.
Offshore PV
Offshore PV applications, such as floating solar, offer many advantages, but the complex marine environment – exposed to seawater, sea ice, sea wind, waves, hail, UV radiation, and halobios – presents significant challenges. These include high salt mist, intense UV exposure, high mechanical load (vibrations from sea breeze, waves, and hail), high humidity and heat, and hot spot risks. JA Solar addressed these challenges by launching 2 types of DeepBlue 4.0 Pro series modules: SkyBlue (for pile-mounted installations) and OceanBlue (for floating applications). The SkyBlue module features double-layer coated front glass for moisture and salt-mist resistance, moisture-resistant encapsulation, MC4 connectors combined with waterproof plugs, and a high-thickness oxide film frame. For the OceanBlue version, JA Solar incorporated polyurethane frames for high weather resistance, strength, and electrical insulation. Additionally, this module uses high-water-resistant sealants to ensure resilience against moisture ingress and UV degradation. Liuzza explained that seawater infiltration can lead to Na+ and Ca+ precipitation in the glass, reducing light transmittance. According to in-house light transmittance loss and degradation tests, high-weather-resistant double-coated (DLC) glass showed significantly lower transmittance loss and light degradation. Both offshore PV modules’ reliability and durability have been validated through the TÜV NORD offshore module sequence test.
Anti-dust Modules
JA Solar's anti-dust modules feature a patented short-frame design with drainage holes to prevent dust accumulation. This frame design offers several benefits, including high load strength, high reliability, ease of manufacturing, and compatibility with various installation types. The high-generation capability of this anti-dust module has been validated by third-party inspection agencies, such as TÜV NORD.
Anti-glare Modules
Liuzza then explained the advantages of JA Solar’s anti-glare modules. Glare, caused by the reflection of strong outdoor light, can lead to visual discomfort. PV module installations in areas such as freeways, highways, or airport premises require glare- and flicker-free performance to minimize visual hazards for pilots, air traffic controllers, workers, and drivers. JA Solar addressed these potential issues by adopting a double-embossed front glass surface, rather than conventional anti-reflective coating (ARC) glass. This special glass features an enhanced rough surface, which disperses reflected light and reduces the brightness of reflected light spots, thus minimizing glare. The company offers a wide range of anti-glare DeepBlue 4.0 Pro series modules, all certified by independent third-party agencies.
