400w Solar 2021

[Markanderson]

I am struggling making a decision. I want to install somewhere around the 400 watt range of solar panels. Do I use 4- 100watt panels or 2- 200 Watt panels or 3-175 watt panels. I am looking at Rich Solar, HQST, Renogy, Newpowa. I see all the reviews for 100 watt panels but not many reviews for higher watt panels. Rich Solar has a nice 400 watt package but I am not sure about the 40amp MTTPS controller it comes with as I do not see any reviews for thie device. I am thinking that may be the way to go but use a Victron MPPT controller. Any real experiences out there and are there any new products or updates for 2021?

200W or larger are usually much more economical, if you have no other constraints
such as physical shape or voltage. Bruce Roe
