Solar photovoltaic module remote access module switch and real-time temperature monitoring

A remote-access module switch and monitoring circuit having a pair of output electrical leads, and a pair of input electrical leads connected to a pair of electrical power leads of a solar photovoltaic module, comprising:

• a. A series switch placed between said pair of output electrical leads and said pair of input electrical leads, said series switch remotely controllable to be in one of two modes:
• (i) turned on to allow power delivery from said pair of electrical power leads of said solar photovoltaic module to an electrical load and, (ii) turned off to place said solar photovoltaic module in an open-circuit mode with an open-circuit module voltage across said pair of electrical power leads;
• b. A module voltage measurement circuit for periodic real-time measurements of a module voltage as measured across one of said pair of input electrical leads and said pair of output electrical leads during a power generation period by said solar photovoltaic module between its daily wakeup time and sleep time, including periodic real-time measurements of:
• (i) said open-circuit module voltage when said series switch is turned off and, (ii) said module voltage when said series switch is turned on;
• c. A module current measurement circuit for periodic real-time measurements of a module current flowing through said pair of electrical power leads during said power generation period, including periodic real-time measurements of said module current when said series switch is turned on and a parallel switch is turned off;
• d. A temperature sensor for periodic real-time measurements of a circuit temperature of said remote-access module switch and monitoring circuit, said circuit temperature being the same as a wake-up ambient temperature at the daily wake-up time of said solar photovoltaic module and said remote-access module switch and monitoring circuit, and said circuit temperature being the same as a sleep ambient temperature at the daily sleep time of said solar photovoltaic module and said remote-access module switch and monitoring circuit;
• and
• e. A communication circuit for sending measurement data to a remote receiver.
