For the solar system, many people are familiar with it. A photovoltaic system, also PV system or solar power system, is a power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling and other electrical accessories to set up a working system. When you going to buy some products, many of sales will ask you the gird-tie system or off-gird system…. How hard for me to tell the system, I even don’t know what’s it.

The first one is Large power station, these projects usually have more than 100kw system. The second one is Distributed power station, these projects are usually installed in the roof. Many people will choose them to power generation and provide to their own inquires or sell it to the government. I believe that many people have installed them and understand what I am saying. For the off-gird system, The phrase refers to systems that have no connection with the utility grid, and must make all the electricity necessary for the home, business, or application. In fact, The LED lights with panels in the garden、the solar pump in your pool、the portable solar battery when you are travelling outside.
