Solar help requested

Any input based on experience ???

Looking at 24v solar panels and want input from you.

NewPowa 200w
Renology 300w
Sungold Power 200w
Solarland 190W

Im planning on Victron smart controller 100/50 and 2 BB 100ah liihium batteries.

The panels are the issue I have not settled on yet. his system will be growing as money becomes available.

    Other than the Renology panel option, you are “skinny” on watts. One watt per battery amp hour is the base minimum. If you are intending to “grow” your system, install adequately sized wire....the first time.

    Look at panel size, roof space and roof access. And $/watt and watts/sq ft. For those reasons I choose 60 cell panels vs 72 cell panels.

    And future additional panels. I don't need more but could add 2 more with a second controller.

    My install is 3x250W in serial which also gives better shade output than parallel. Plus I mounted them higher off the roof to eliminate A/C shadows.
