I am located in California, my power company is PG&E.  Last year due to over production of solar electricity I gave over $1,000 of electricity to the power company for $40.  Does anyone know any energy credits monitoring software so I could see where I stand when it becomes true-up time with the power company.  What makes this tricky is the rate plan I am on with PG&E is a Time of Use.  On weekdays the amount of money PG&E buys excess electricity changes 5 times per day and can rage from $0.14 to $0.58.

Anyone know of a software program which works with Time of Use solar customers which will let you know where you stand financially with your power company?

If it's a fixed schedule or there's a place online to download it, write your own Python script to calculate it.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

What kind of production meter are you using?

I am using an Enphase IQ Envoy.  I don't think data can be exported.

I could use Python and have used Excel.  The problem is there are no APIs.  One has to manually export the data, manually clean-up the data and import.  The power company has some API, but it requires a authentication and isn't that easy.  Then they change the structure of the data for time to time and then it doesn't work anymore.

Actually, Enphase does have an API.  I played with it a little and was able to access performance data, and later a developer we hired used it in an app for fleet monitoring.  See https://developer.enphase.com/ .

First of all, congratulations on acquiring a company, especially related to green electricity. What about the charts? You can look at this site: https://www.simplyswitch.com/energy/guides/find-the-cheapest-gas-and-electricity-provider/, charts of different global companies related to your business. I have a couple of questions about this business. How often do you need to change the solar panels? And how many are enough for your company, for a certain number of customers? I'm just thinking about doing this business too, and I do not know where to start.

The charts are daily production which doesn’t help.  In one day the rate can change 5 times.  And then there is a summer and winter rate.
