How Solar Panels Connect To The Grid

You will need an inverter to transmit the dc energy into ac before you can use the power in your home or connect to the grid.

How solar panels connect to the grid. For larger systems anything above a 3 68kw output the dno needs to give permission before you can start supplying energy to the grid. Cps energy s solar pv rebate program provides a way for homeowners to save 1 60 a watt on the first 25 kw and then 1 30 per watt thereafter. All solar farms connect to a specific point on the electrical grid the vast network of wires that connects every power generation plant to every home and business that consumes power. Surplus electricity is fed back into the main grid.

Whenever the sun shines and even in overcast weather the solar cells generate electricity. Larger systems can qualify if the efficiency of the inverter results in a 3 68kw output e g. This is important because solar energy is intermittent. When a homeowner decides to add solar panels to their home in most cases they will choose to be grid connected.

Essentially this means that if your system s output is less than 3 68kw a 3 68kw system with a 100 efficient inverter for example then it can be connected to the grid. The interconnection standards program offers a rebate for connecting your solar systems to the grid. So the solar panels will connect to the inverter to transmit the dc energy into ac. The grid connect inverter converts the dcelectricity produced by the solar panels into 240vac electricity which can then be used by the property household.

That point is called the point of interconnection or poi. Home solar panels and the grid. There are two ways to interconnect. The inverter will most likely need to be connected to the above mentioned disconnect depending on your state.

Here are some examples. Though a substation or through a tap. It stops working when the sun goes down.
