Worked out from your last week of actual usage: how much extra battery would be needed to get through a typical night, and how much extra solar to cover the house and refill the battery the next day - with a buffer built in for a worse week than usual.

Enter the exact date and time you read the meter, not just the date - the accuracy of the expected-reading calculation above depends on it.

The date of your earliest cost entry below is treated as the date the system was installed, and the date you first entered it here is when tracking started - if you went solar before joining mySolarIQ, we'll estimate your savings for that earlier gap using your real average once there's at least a week of data, and that estimate keeps improving as more comes in.

Add a new entry any time the system grows (e.g. more panels or batteries added later) - each one is counted towards the total. Made a mistake? Edit or delete any entry below.
