In the simplest terms, a grid tie solar system, also known as a grid-connected or on-grid solar system, is a solar setup that is tied to -connected to- the traditional power grid. While the sun shines, it provides energy to your home, and excess energy is sent back to the grid.
There are two basic approaches when you connect a grid-tied solar panel system. You need to know how to connect solar panels to your house. The most common is a "load side" connection.

How does storage help us balance the grid? Energy storage allows us to move energy through time, capturing it when we have too much and saving it for when we don''t have enough. When we have excess electricity, perhaps on a really windy day, we don''t want the extra energy to go to waste. If we can store the electricity to use later, when
