Techniques for geolocation and cloud detection with voltage data from solar homes

A computing device comprising:

• one or more processors;
• and
• a memory storing instructions that when executed by the one or more processors causes the computing device to perform operations comprising:
• obtaining, using one or more sensors, a first set of voltages indicating a voltage on a first power line over time, the first power line being located at a first solar generation site where a portion of power on the first power line is generated from solar irradiance at the first solar generation site, wherein the first power line is coupled to a utility provider, wherein the computing device is included in a communication network and comprises a meter device located at the first solar generation site;
• receiving a second set of voltages that were measured by another computing device at a second power line and indicate a voltage on the second power line over time, the second power line being located at a second solar generation site where a portion of power on the second power line is generated from solar irradiance at the second solar generation site, wherein the second power line is coupled to the utility provider, wherein the another computing device is included in a communication network;
• cross-correlating the first set of voltages and the second set of voltages;
• determining a wind vector based on a first location of the first solar generation site, a second location of the second solar generation site, and the cross-correlation of the first set of voltages and the second set of voltages;
• and
• computing, based on the wind vector, a point in time when solar power generation of a third solar generation site at a third location will change, wherein a third power line is located at the third location, wherein the third power line is coupled to the utility provider and a portion of power on the third power line is generated from solar irradiance on one or more third solar panels located at the third location.

A non-transitory computer-readable medium storing program instructions that, when executed by a computing device, cause the computing device to perform operations comprising:

• sensing, using one or more sensors, a plurality of first voltages on a first power line that indicate a voltage generated, over time, by one or more solar panels at a first location, wherein a portion of power on the first power line is generated by the one or more solar panels at the first location, wherein the first power line is coupled to a utility provider, wherein the computing device is included in a communication network and comprises a meter device located at the first location;
• receiving, via a network, a plurality of second voltages that were measured by another computing device at a second power line that indicate a voltage generated, over time, by one or more solar panels at a second location, wherein a portion of power on the second power line is generated by the one or more solar panels at the second location, wherein the second power line is coupled to the utility provider, wherein the another computing device is included in a communication network;
• determining a time delay between a first variation in the plurality of first voltages and a second variation in the plurality of second voltages by determining a cross-correlation between the plurality of first voltages and the plurality of second voltages;
• determining a wind vector based on the first location, the second location, and the time delay;
• and
• computing, based on the wind vector, a point in time when solar power generation at a third location will change, wherein a third power line is located at the third location, wherein the third power line is coupled to the utility provider and a portion of power on the third power line is generated from solar irradiance on one or more third solar panels located at the third location.
