Considering adding solar panels to combined use SFH in CA

[Lena Kendall]

Hello everyone, I'm new here and am looking for some advice.

I own a SFH in Northern California and rent out two rooms while living in the master. I am interested in getting solar panels for the home and am wondering how that affects my tenant's utilities bill. I have gathered from other forums and discussions that if a home has solar panels, the tenant is not charged any electricity bill unless there is an overage. Am I correct in assuming that you cannot charge a tenant for use of solar-powered electricity if there is no actual bill from the utilities company (PG&E)?
