Solar Energy Metering, Communications, And Control System
Methods, systems, and computer readable media are disclosed for monitoring photovoltaic solar systems. In some examples, the system includes a solar power measurement input for coupling to a solar panel system, a measurement circuit configured to measure power produced by the solar panel system using the solar power measurement input, and a data transmission system. The measurement circuit is configured, by virtue of the measurement circuit including electrical components rated to at least a certain tolerance level, to take revenue-grade power measurements from the solar power measurement input with a level of accuracy that meets a national or international metering standard. The data transmission system is configured to transmit the revenue-grade power measurements from the measurement circuit to a remote system.

- 1. A system comprising:
a solar power measurement input for coupling to a solar panel system; a measurement circuit configured to measure power produced by the solar panel system using the solar power measurement input, wherein the measurement circuit is configured, by virtue of the measurement circuit comprising a plurality of electrical components rated to at least a certain tolerance level, to take a plurality of revenue-grade power measurements from the solar power measurement input with a level of accuracy that meets a national or international metering standard; and a data transmission system configured to transmit the revenue-grade power measurements from the measurement circuit to a remote system.
- 11. A system comprising:
a solar power measurement input for coupling to a solar panel system; a measurement circuit configured to take a plurality of power measurements from the solar power measurement input; and a data communication system configured to transmit the power measurements from the measurement circuit to a remote system, wherein the data communication system comprises a first transmitter configured to transmit on a first protocol and a second transmitter configured to transmit on a second protocol different from the first protocol, and wherein the data communication system is configured to transmit the power measurements on the first transmitter and, in response to detecting unavailability of the first transmitter, switch from transmitting the power measurements on the first transmitter to transmitting the power measurements on the second transmitter.
- 20. A system comprising:
a solar power measurement input for coupling to a solar panel system; a measurement circuit configured to measure power produced by the solar panel system using the solar power measurement input, wherein the measurement circuit is configured, by virtue of the measurement circuit comprising a plurality of electrical components rated to at least a certain tolerance level, to take a plurality of revenue-grade power measurements from the solar power measurement input with a level of accuracy certifiable for a utility company; a data transmission system configured to transmit the revenue-grade power measurements from the measurement circuit to a remote system of the utility company, wherein the data communication system comprises a first transmitter configured to transmit on a first protocol and a second transmitter configured to transmit on a second protocol different from the first protocol, and wherein the data communication system is configured to transmit the revenue-grade power measurements on the first transmitter and, in response to detecting unavailability of the first transmitter, switch from transmitting the revenue-grade power measurements on the first transmitter to transmitting the revenue-grade power measurements on the second transmitter; and a weatherproof housing enclosing the measurement circuit and the data transmission system.
