Are solar panels connected to the grid?

Most solar panel installations throughout the U.S. are connected to the grid. With grid-tied systems, you can draw power from the power grid when your solar panel system isn't producing electricity.

Do utility companies let solar panels connect to the grid?

Utility companies won't just let any solar energy system connect to their grid; they need to ensure that your solar energy system meets necessary electrical safety standards. They'll also ensure that your solar panel system will meet their respective net metering guidelines.

Are PV systems grid-connected?

Since 2004, most PV systems in the United States are grid-connected —they are connected to an electric power grid. These PV systems are installed on or near homes and buildings and at utility-scale power plants that have at least 1 megawatt of electric-generation capacity.

Can a solar panel system be installed off the grid?

While installing an off-grid solar panel system and avoiding the interconnection process entirely is possible, it's often not cost-effective. For the average residential property, going "off the grid" with solar power requires several solar batteries to store energy.

How do I connect a grid-tied solar panel system?

Always refer to the NEC code in effect or consult a licensed electrician for safety and accuracy. There are two basic approaches to connecting a grid-tied solar panel system, as shown in the wiring diagrams below. The most common is a "LOAD SIDE" connection, made AFTER the main breaker.

Are on-grid solar panels a viable source of energy?

Solar energy is becoming increasingly popular as a clean and sustainable source of power. While many people are familiar with solar panels and their ability to convert sunlight into electricity, the workings of an on-grid solar system may still be a mystery to some.
