@kenny-crane Thanks, we have this also going on a single 260W solar module connected to a standard electricity (kWh) meter. That meter outputs the MODBUS TCP/ RTU protocol. Then that connects to the python program that communicates with the solarcoind full node and sends the transactions. So it is all open source. The first step is to setup your solar system to a battery (if you are off-grid), and /or your inverter (if you are on-grid). Then get a modbus enabled electricity meter. Or better still, work with a solar inverter maker that has their own LAN API like Enphase. You could report back here or join the #electricchain slack if you need more help. There are a number of people working on this in that slack.
