Should I get a solar battery?
You must install batteries if you want your solar panel system to provide power during outages. Unfortunately, adding solar batteries will increase the cost of your solar system significantly, but you can still recover 30% of it with the solar tax credit. Solar systems with batteries are also popular for off-grid homes.
What are the common misconceptions about solar batteries?
A common myth about solar batteries is that if the power goes out, a solar battery will run your whole house for a long period of time. A solar battery will allow primary functions to continue, such as the blower on the furnace, LED lights, and refrigerator. However, even with a full charge, the best solar batteries will power most homes for a limited period, especially in cloudy weather. Therefore, most solar homeowners prioritize which electric loads to run during power outages.
Can I add a battery to my solar panel system later?
Yes, you can retrofit your existing solar system by adding batteries. However, AC-coupled solar batteries are easier to incorporate with existing solar systems without replacing your existing inverter because they contain a built-in inverter. Some of the leading AC-coupled batteries are the Panasonic EverVolt, Sonnen eco, and the Tesla Powerwall.
What else should I know about solar batteries?
Your solar installer will likely have a preferred solar battery. If you decide to get a solar battery storage system, you may want additional information on the battery that comes with your solar PV system. Other common questions to ask your installer about solar batteries include:
- How long will my solar battery last during a power outage?
- How long does it take to charge my solar battery?
- What is the lifespan of the solar battery bank?
- How can I use the solar battery app to monitor my battery charge level?
