Maximum kW for Solar Panel Installation?

I am building a new house that will be off the grid and I want to install at least 30 kW of solar panels to supply all my energy needs. I have more than 2,300 SF of southern facing roof space which should be plenty of room. The largest choice on the web site is 16 kW but does anyone know if you can install more than that or if there's any reason that there's a limit?

  • If not grid-connected, there shouldn't be a limit. If grid-connected, most utilities in the USA will limit the amount of solar power so that you don't overproduce. Also, fire codes in many locales will limit pannels to some areas. For example, they require 3 feet between an edge and the panels, which reduces the usable roof area.
