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.
We generally see that the less efficient and cheaper solar panels tend to produce more electricity in a year for the same price as more expensive high-efficiency solar panels. Our users spend an average of $1,217.63 less per year on electricity. That's including the cost of solar panels.
