Our solar systems are based on the size of the home, projected usage and local utilities. Grid-Tied power allows a home to still be tied to the local utility company. The home produces power that can be used during the day. If extra power is produced it is banked with the utility to be used when the system is not producing.
Different utility companies have different net-metering programs. Some buy back the power at wholesale price, but resell it back to consumer at retail. It is very important to know your utility company’s program. Some utility companies even have large rebates for customers who install a PV system.
The City of Austin and CPS in San Antonio are some of the leaders in rebates to the consumer in the state of Texas.
