The expansion went fine. Initially were going to just add panels to my existing inverter. However, It became clear it was beneficial to add a second inverter so we could mount a few panels on the backside of my house(NW facing) so there was generation in the afternoon.
Something I forgot to add earlier is to choose an installer who is experienced in custom designing a layout to get the maximum output based on the orientation of the home, surrounding vegetation, eaves/dormers/upper levels which can shade the panels.
My house is ESE-WNW orientation. This means that neither my "front" or "back" produces a maximum power output, but I can put panels on both sides of the home and get decent generation.
On the front side(facing ESE) I had 18panels originally..we added 2 additional panals(to fill the roof) hooked to original array.
Add on array has 8 panels facing WNW hooked to a much smaller inverter. I could add more panels to the back--but it may not be worth it as part of that roof is shaded by trees along the side of the property during the late afternoon when the WNW panels would have the most exposure to the sun.
Luckily my house faces south.
Was just thinking of adding another 10 panels or so, but doing it myself. I have a ground array also.
