Compare Two Sums Every n Rows with Varying n

I am trying to size a solar array such that it can charge batteries sufficiently enough to meet a varying residential energy load.
I want to see if "Battery Charging Power" is greater than or equal to "Battery Discharging Power".
It'd be incorrect to just compare the two total sums over the whole year; it needs to be done on a daily basis due to varying solar output and residential load.
I have already summed up the "Battery Dis/Charging Power" with the help of a user on this forum a few weeks ago, so now I am trying to check on an individual, per day basis, if the solar output of the day is going to support the required battery output for the following day/night (until solar output "turns on" again).
I attached some data - I did the whole year just in case that much is needed to check. Any help or advice would be greatly appreciated!!!

This was great - thank you!
