Going solar is a smart investment that can help you save money on your energy bills for decades to come. But before you can install home solar panels, you need to make sure your electrical panel is ready to support them.
In many cases, you won’t need a home electric panel upgrade for solar. But there are also many cases where an electric panel upgrade is necessary, especially if you live in an older home or you’re thinking about expanding your photovoltaic (PV) system down the road with battery storage or an EV charger.
When thinking about electrical panel requirements for solar, amperage is the main factor to consider. Electrical panel breakers are rated by the amount of power they can handle, in amperage (or amps).
To be ready for solar, your panel’s main breaker needs to be rated for at least 200 amps, in most cases. (Larger homes will require a larger breaker for solar, while some smaller homes may be able to manage with less amperage.) If your main breaker is rated for less than 200 amps, it will not be able to handle the power load your solar panels feed into it. This can lead to many issues, including electrical fires.
Evaluating your electrical panel before installing solar panels will help ensure safe, reliable operation. Common signs that you will need to replace your electrical panel before installing solar panels include:
You might not have to upgrade your electrical panel to go solar, but it usually makes sense to do so anyway. The cost of upgrading your electrical panel is relatively low, and installing a solar-ready breaker will ensure you get the maximum value from your investment in solar panels. With a new electrical panel, you’ll get the peace of mind that comes with knowing your home’s electrical system is operating as safely and efficiently as possible. And, if you decide to make any electrification upgrades in the future or expand your solar energy system, you’ll be able to take on those projects confidently, knowing your breaker box can handle the increased load.
