When you want to retrieve data from a database, you ask for the data by using Structured Query Language, or SQL. SQL is a computer language that closely resembles English, but that database programs understand. Every query that you run uses SQL behind the scenes.
The inverter turns the DC electricity generated by the solar panels into 120-volt AC that can be put to immediate use by connecting the inverter directly to a dedicated circuit breaker in the electrical panel.
Solar panels (also called âsolar modulesE produce direct current (DC), which goes through a power inverter to become alternating current (AC) â electricity that we can use in the home or office, like that supplied by a utility power company.
