A:Not necessarily. If you are planning on remaining connected to the public utility grid (which we recommend), then you might still have an electric bill at the end of every month. The only difference is that your bill will be significantly smaller because your solar energy system will have generated the majority of the power you used as opposed to public generator systems. If you disconnect from the grid entirely, then your bill will disappear. However, we do not recommend this unless, as it can leave you without power should your power supply diminish.
