JA Solar Panels

For a long time JA have been one of the biggest names in the solar industry, their panels have truly passed the test of time and offer some of the highest efficiency panels on the market. 390W A Grade CEC Approved Solar Panels Teir 1 24V By JA Solar.


Key Features

  • JA 4BB design module reduce cell series resistance and stress between cell interconnectors improves module reliability and module conversion efficiency
  • High output, 16/99% highest conversion efficiency
  • Designed for DC IEC 1000v applications
  • Anti reflective and anti-soiling surface reduces power loss from dirt and dust
  • Outstanding performance in low light irradiance environments
  • Excellent mechanical load resistance: certified to withstand high wind loads (2400Pa) and snow loads (5400Pa)
  • High salt and ammonia resistance certified by TUV Nord
  • Detailed system information such as solar power, usage history & battery status is displayed on the intuitive Cerbo GX panel. When connected to your home network all this live information can be viewed on your smart phone or a PC, and if you have the internet view your system from anywhere in the world using Victron’s free Remote Management portal (called the VRM portal). See the Cerbo GX brochure on the downloads tab for more information.
  • Create a Grid-Hybrid system, where your Solar energy is used & stored as first priority**Power will be supplied primarily from the solar panels & battery bank. If required, the grid can help power loads through the inverter automatically. This design principle uses your solar & stored energy first before using the mains grid power. If your batteries are full, and there is more solar power than your loads need, the extra power can be exported back to the grid for feed-in tariffs.

System Performance

Solar array performance varies with location, the annual daily average in Australia is between 4 to 5 hours equivalent of full power from the array per day, with more in summer and less in winter. A large solar PV array design principle reduces the amount of time the batteries will be low on charge, which maximises their life expectancy & provides you with far more reliable power.
