The Japan Weather Association (JWA) announced new service for corporative activities on June 29, 2012. It is named PV-DOG, a diagnostic system for domestic photovoltaic (PV) generation systems.

Although existing PV generation systems display the actual power output on their monitor screens, they do not have a function to compare the output to solar radiation, which is closely linked to output, and therefore users cannot determine whether they are gaining the expected output for the solar radiation.

The new PV-DOG, which was developed by JWA, had previously been researched through projects commissioned by the New Energy and Industrial Technology Development Organization, makes a simple diagnosis as to whether the PV generator is operating normally. It compares the actual output of a household that has installed a PV generator against expected power output estimated from weather data at the nearest observation station of the Automated Meteorological Data Acquisition System (AMeDAS) to makes a simple diagnosis. In the event of failure or problems, PV-DOG displays a message on the screen to inform the user.

This new service is provided for corporation from JWA, not for individual user of PV generation directly.
