Evaluate your electricity needs and crunch the numbers.
Electricity Needs
Determine your current and future energy needs.
- Current - Check your electric bills. A 12-month history will be best as your usage will vary from season to season.
- Future - A typical PV system will last 25 years, and your energy needs may change over time. If you are thinking of expanding or electrifying your home, or buying an electric vehicle, your future needs may increase. On the other hand, if you have kids that may be moving out, perhaps a smaller system might be more feasible and the better option.
Rates
Silicon Valley Power has one of the lowest electricity rates in California and may cause your savings to be less than PV systems in other electric utility territories. Make sure to provide your contractor Silicon Valley Power's Net Energy Service rate schedule to help determine your savings.
