How does Local Electric Utility measure my solar energy exports?
They install a bi-directional smart meter to track exactly how many kilowatt-hours you pull from the grid versus how much surplus solar you push back.

String inverters link panels to a central hub (vulnerable to shading), while microinverters attach to each individual panel to maximize output independently.
What are the current electricity rates for Local Electric Utility customers in Top 10 Local Solar Installers San Diego?
Local Electric Utility currently charges an average of $0.22 per kWh. Installing solar allows you to lock in a lower effective rate and hedge against annual utility inflation.
