Perhaps you design a system to suit your current electric usage, but then want to add an electric car into the mix. So the question is can you add to a solar electric system. The answer is a qualified yes.

Perhaps you hope to add batteries in the future. All of this is significantly easier if your start with the end system in mind. Give us a call 406-381-5643.
