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.
Cost is not price. The solar panels will be produced 2016Q1, And 55 cents per watt is actually pretty good for such high efficiency panels. The panels produced from a test production line will not be 55 cents per watt. 55 dollars per watt is closer. I think you are underestimating the SIZE of the pilot facility.
