When upgrading your home with a new solar power system, you may wonder, “How many solar batteries do I need?”
The answer to this question depends on a few key factors. Trusted green-energy technicians help you determine which solution is right for your property. Consider the following information, then optimize your home with a solar battery installation.
What Is a Solar Battery?
A solar battery is a device that stores excess energy produced by a solar panel system. Most people invest in these solutions to prevent blackouts during emergencies. However, some rely on batteries to save money on energy bills and reduce their overall dependency on community power grids.
Batteries come in many sizes, but the average battery capacity is about 10 to 20 kWh.
A single 10 kWh battery can power a 1000 W house for around ten hours. Alternatively, it can power a 500 W device for up to 20 hours.
How Many Batteries Do I Need?
“How many solar batteries do I need?”
Now you can begin planning your battery bank. Choosing the right solution for your home depends on your energy needs:
- How much energy does your home consume?
- Do you want to stay off the community power grid?
- How much money are you willing to spend upfront for an installation?
A single-battery solution is an excellent way to keep your essential appliances running during power outages. You can save time and money by avoiding gas-powered backup generators to keep the lights on.
Two to Seven Batteries
Solar panels stop functioning at night. Snow and debris can also obstruct them, reducing the system’s performance. When your solar panels stop producing energy, your home will consume power stored in your batteries.
With two or three batteries, you can save money during peak power usage hours (nighttime or during natural disasters). However, you will likely still rely on your local power grid to pick up the slack.
Eight or More Batteries
Many people invest in solar energy to become self-sufficient. Connecting your panels to eight or more solar batteries could optimize your power usage and keep you off the grid entirely.
These installations will save you money over time, reducing your reliance on third-party electric companies. However, you can expect high upfront expenses. For example, some lithium-ion batteries cost between $5,000 and $10,000 per installation.
