The process for obtaining net-metering approval involves coordination with the local electricity distribution company. Prospective buyers should anticipate that the speed of utility processing can vary, making early engagement with the local provider advisable. This service is suited for residential and commercial clients who require grid-tied solar solutions and are prepared to manage the necessary utility paperwork alongside the installation process.
