It all retrofits on any home nicely. All you need is an open breaker space in the main panel to tie in the green system which will flow power into the panel and out to the meter. Most systems size will use a 60A 240 breaker and it goes up from there to whatever size you design.

If you go with battery back-up power which is a much better featured system, you create a sub panel with your most critical loads like well water, furnace blower and thermostat, sump pumps, communication, and emergency lighting.

Even all that is easy to do retrofit nicely with a sub panel next to the main.

Biggest concern at this point to me would be lots of south facing roof space with very little obstructions like pipes dormers etc. and to look at the peak direction VS most common wind direction for the location.
