No. The majority of PV systems are grid-connected systems where you will get power from both your PV system and Silicon Valley Power. However, you could have a stand-alone or off-grid system where you solely use energy from your PV system, but these systems are rare.
What is the lifespan of a PV system?
A PV system can last more than 25 years.
Your PV panels typically come with a manufacturer’s warranty of 25 years but last a lot longer than that. However, after 25 years, your panels might produce less energy than previously guaranteed by the manufacturer.
Your inverters will likely last 10 to 15 years and come with a manufacturer’s warranty of 10 years. You will need to replace these during the lifespan of your PV panels.
What is the maintenance for a PV system?
Minimal maintenance is required. You may need to wash your panels and keep them free of debris a few times a year.
Is a PV system cost-effective?
Going solar is a low-risk investment. However, since Silicon Valley Power has one of the lowest electric rates in California, a PV system may have less financial benefits than a PV system in a different electric utility’s territory.
Can customers get credit for producing electricity?
Yes. Net energy metering allows customers to offset their electric usage by exporting power to the electric grid. Read more about net energy metering and your bill here.
