If the open-sourced OnGrid Tool helps you, please consider donating to Slow Power / Mike (its host) — thru Slow Power's Give page.

Mike would really appreciate the support.

It will put him in a better position to support open-source OnGrid Tool users.

It'd also help him continue offering free resources thru Slow Power (including, hopefully, free-and-open-source energy modeling software built for year 2026+).

Thanks for considering.
