TEP's Solar Connect program credits excess generation at favorable rates, and TEP's Energy Storage Rewards program pays up to $720/year for qualifying battery systems — making solar-plus-storage especially cost-effective in southern Arizona. Pima County's green building guidelines and the University of Arizona's sustainability focus mean local installers often hold the deepest TEP interconnection experience in the state.
