Frequently Asked Questions About Solar Systems with Energy Storage
How does a solar system with battery backup work?
A reliable battery bank is designed to charge in a few hours of full sunlight and slowly discharge throughout the evening and night. Thus, deep-cycle models are designed for this type of use and work well in conjunction with solar panels.
What types of solar systems have batteries?
There are two primary kinds: grid-tied solar systems with battery backup and off-grid solar systems. Grid-tied systems can draw power from the utility grid except during power outages.
Off-grid solar systems are typically located far enough from the power grid that it is prohibitively expensive to connect to it. The off-grid solar system is then the primary source of power for the home.
What loads get powered by my batteries during a grid outage?
Grid-tied solar panel systems with battery backup operate during electrical outages or whenever your house needs the stored solar power. Sundog Solar installs a critical load panel to determine which critical loads are powered by the batteries.
Home or business owners prioritize the most important loads until grid service resumes. It is often not practical to power all the appliances in the home, such as air conditioners and the oven, as the capacity of the batteries limits the total energy storage output.
A Sundog Solar expert can help you determine which loads are most important and to size your system to provide the maximum value to your home or business. With years of experience installing a variety of quality solar equipment, charge controllers, and solar batteries, the Sundog Solar team is skilled in seamlessly integrating solar systems with emergency backup power.
What are AGM batteries?
Absorbed Glass Mat or AGM batteries are popular in off-grid solar installations. If these units are broken, no free liquid leaks out because they contain only enough liquid to keep the mat wet. Thus, AGM batteries are designed to provide an excellent value and are a worry-free technology.
Does Sundog Solar install lithium-ion batteries?
Yes, we install the new generation lithium-ion battery technology. The Sundog Solar team installs a variety of batteries for solar systems and can customize the installation to the unique energy needs of your home or business. Lithium-ion batteries are lighter weight and smaller than lead-acid models and have a significantly longer lifespan. Unfortunately, lithium-ion batteries also tend to have a higher upfront cost than lead-acid batteries but feature longer warranties.
How much do batteries increase the cost of a solar system?
Adding batteries to a solar energy system adds between $8,000 to $20,000 to the cost of the solar system if using advanced lithium-ion batteries. The exact cost depends on the power needs of the home and the solar battery manufacturer. Installing lead-acid batteries costs significantly less, but they typically have shorter warranties and lifespans.
