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.
How many kWh can your solar panels produce? The amount of power (kWh) your solar energy system can produce depends on how much sunlight exposure your roof receives. The amount of sunlight you get in a year depends on both where you are in the country, and what time of year it is. California has more sunny days annually than New England.
