SolarEdge Insights

Just a fun analysis of how much you have saved from installing a SolarEdge PV system.

What you need

API Key - Provision it in https://monitoring.solaredge.com
Site ID - Retrieve it from the above url
Electric Rates - Get it from your bill

Setup

Install MongoDB
Add the API Key and Site ID to the .env file. An example file (.env.example) is checked in.
Add your rates to solaredge-insights-server/src/lib/insert-rates.ts
- You may need to modify the rate schedule (peak, off-peak, shoulder) in solaredge-insights-server/src/lib/retrieve-costs
- Additionally it doesn't handle anything with blocks
Import your rates into MongoDB
Set the retrieval start and end dates in solaredge-insights-server/src/temporal/client.ts

Importing rates

Run this:

ts-node src/lib/insert-rates.ts

Execution

temporal server start-dev to start Temporal Server
1. Use temporal server start-dev -db-filename filename if you want to persist it
npm install to install dependencies
npm run start.watch to start the Worker
In another shell, npm run workflow to run the Workflow Client

The Workflow should return something like this:

> solaredge-insights-server@1.0.0 workflow
> ts-node src/temporal/client.ts

Started workflow workflow-orchestrator-2019-08-19
Result: {"startDate":"2019-08-19T00:00:00.000Z","endDate":"2019-12-31T00:00:00.000Z","feedInCost":170.63244,"selfConsumptionCost":481.7893331,"totalCostSavings":652.4217730999995}

Querying Run State

In another shell, npm run query to run the Workflow Client.

Caveats

For now, you need to navigate to http://localhost:8233/namespaces/default/workflows to view the results
I need to add tests..... I know there's something weird about the date array....
Solaredge states you got a maximum of 300 API calls daily
Need to retrieve a list of running workflows in Temporal Server to determine which one we want to run the query on

Things to improve

Use a workflow to import the electricity rates and use queries to retrieve it
- Remove MongoDB
Allow some customisation into how the peak, off-peak and shoulder rate hours are documented. Currently it is hardcoded to Victorian (Australia) schedules
Add a UI so it's prettier to convince your better half
