Home solar offset: what's a good number?
If you’re exploring home solar for the first time, there’s probably a lot of terminology that’s new to you. One that confuses a lot of people is the concept of solar offset. Simply put, a home solar system reduces the number of kilowatt-hours of electricity that the utility company bills for. The amount of reduction is the solar offset, and it’s usually expressed as a percentage of the home’s annual electricity usage.
