A review of electricity usage and energy saving methods
The more electricity your panels generate, the less electricity you will need to buy from your utility—and the lower your utility bills will be.
If you live in an area where “net metering” is available, you can save even more money. Net metering is a term for utility programs that give you a bill credit for any extra electricity that your system produces. This excess power flows back to the central grid, where it can be used by others. The amount of credit you get depends on your utility’s particular policies.
Like inverters, meters are getting smarter, and are now able to accomplish more. Smart meters open the door to give consumers the ability to better control their energy costs.
Most people don’t realize this, but utility electricity prices change many times during the day, much like the stock market. Consumers are unaware of these price shifts because they don’t buy power from the wholesale power market; instead they pay retail rates regulated by their state.
