Grid-tie solar systems are popular, but they can be a little confusing. Here are some frequently asked questions to help you understand grid-tie solar systems better.


Grid Tied Solar System FAQs

At JBR Solar, we want to make sure you have all the information you need to make informed decisions about solar energy. Here are more answers to commonly asked questions.

What is a grid-tie solar system?

A grid-tie solar system is a solar power generation system that’s connected to the local electrical grid. The system produces electricity for your home or business, and any excess power is fed back into the grid.

What happens to the excess energy produced by a grid-tie solar system?

In most grid-tie solar systems, any excess energy generated by your solar panels is sent back to the local electrical grid. Depending on your utility company’s net metering policy, you may receive credit for this excess power, which can be used to offset your electricity bill.

Can a grid-tie solar system work during a power outage?

Typically, grid tie solar systems are designed to shut off during a power outage for safety reasons, preventing the system from feeding electricity back into the grid and potentially endangering utility workers. However, some grid-tie systems with battery storage or specific inverter configurations can provide power during an outage.

How does a grid-tie solar system save money on electricity bills?

By generating your own electricity, you can significantly reduce the amount of power you need to purchase from your utility company. Plus, with net metering, you can receive credit for any excess electricity your system sends back to the grid, further reducing your electricity costs.

Do I still need to be connected to the grid with a grid-tie solar system?

Yes, a grid-tie solar system requires a connection to the local electrical grid. This allows you to draw power from the grid when your system isn’t producing enough electricity, such as at night, and to feed excess power back into the grid when your system produces more than you need.

How long does it take to install a grid tie solar system?

The installation time for this type of solar system can vary based on factors such as the size of the system and the complexity of the installation. However, most residential grid-tie solar systems can be installed within a few days.

What are the maintenance requirements for a grid-tie solar system?

Grid-tie solar systems require minimal maintenance. Regularly cleaning the solar panels and monitoring the system’s performance are the primary tasks. It’s also advisable to have a professional inspection every few years to ensure the system is working optimally.

Can I upgrade my solar panel system in the future?

Absolutely! You can upgrade your grid-tie solar system if your energy needs increase in the future. This could involve adding more solar panels or replacing your inverter with a higher capacity one. Always consult with a solar professional, like our team at JBR Solar, when considering an upgrade.

What happens at night or on cloudy days with a grid-tie solar system?

At night or during cloudy days when your solar panels are not producing as much electricity, your system will draw power from the grid. This is one of the advantages of a grid-tie system – it ensures you always have a reliable power source.

What is the difference between a grid-tie and an off-grid solar system?

The main difference is that a grid-tie solar system is connected to the local electrical grid, while an off-grid system is not. Grid-tie systems can draw power from the grid when needed and feed excess power back into the grid, while off-grid systems typically rely on batteries to store excess power for use when needed.

What happens to my solar panels when it snows?

Solar panels are designed to withstand weather conditions including snow. While snow may temporarily reduce the output of your system, the panels typically generate enough heat to melt the snow. Plus, panels are often installed at an angle, which helps the snow slide off.

Can i monitor the production of my sytem?

Yes, modern grid-tie solar systems come with monitoring systems that allow you to track your system’s performance in real-time. These systems can usually be accessed through an app or website, and they can alert you to any issues with your system’s performance.

How are grid-tie solar systems installed?

Grid-tie solar systems are typically installed on the roof of your home or business, although they can also be installed on the ground if roof space or conditions are not suitable. The installation includes securing the solar panels, setting up the inverter and other necessary equipment, and connecting the system to your property’s electrical system and the grid.
