After Solar Installation

Get Connected

After your PV system is installed it will be connected to the electric grid which is required by the State of California. The process of connecting to the electric grid is called interconnection and there are mandatory requirements that must be met before interconnection can be scheduled.     

Generation, consumption and what happens when the sun goes down

It is important to understand the relationship between the electric power your system generates, your consumption of that energy during the day, and what happens after the sun goes down or on days when the sun doesn't shine or during months when the weather is typically cloudy.

At any time of day your PV sytem produces more or less electricty.

Early Morning. In the early morning, as the sun rises, the system produces less electricity because the sun is low in the sky, the light is less intense and the angle of the sun in relation to the panels less direct.

Noon.  At noon when the sun is directly overhead, the light is more intense and hits the panels directly. This time period produces the most electricity of the day and possibly  in excess of what you use.  

Evening.  Solar energy production wanes at night. There is no energy production so your energy will be supplied by SDG&E.

About the surplus energy your PV system generates

Because of this relationship between your solar electric power and your energy consumption you may be able to receive a bill credit for the surplus energy your PV system generates by becoming a Net Energy Metering (NEM) customer.  At the end of the year, you may have a bill credit as a result of your self-generation.

When you install a PV system, your bi-directional meter measures the electricity flowing into and out of your home or business.  When your system produces surplus electricity, it passes through the meter and onto the electric grid. When this happens, the meter runs backward and a bill credit is generated for the value of the electricity.  Depending on your true-up period, you could have a bill credit at the end of the year.
