Energy Budget worksheet

[wholybee]

It seems to be a common question for people in planning a system to ask about sizing battery or solar. And the answer is that they need to work out their usage, which doesn't usually help them. I am sharing here an energy budget spreadsheet used by the Pacific Cup during race preparation. I used it years ago when I did that race, and it is an excellent example of how to approach the task.

(note: the numbers in this spreadsheet are somewhat arbitrary, and should not be relied upon)

And the Pacific Cup page the file is linked from: https://pacificcup.org/kb/energy-management
