Best Battery Backups for Your Solar Array Series: The Tesla Powerwall


When I think of Tesla, I think of one of the best clean energy companies in the world. Not only do they rise above the "go green" efforts in the motor industry, but in my opinion, they dominate the battery space as well. In 2015, they introduced the whole home battery called the Tesla Powerwall.


Tesla’s introduction of residential-use batteries is in line with its legacy of building products with our nation’s future goals in mind. Our goals include utilizing renewable energy resources for transportation and our everyday lifestyles. Including their Tesla Powerwall.


How does the Tesla Powerwall work?


The Tesla Powerwall plays nicely with our ONIT Solar Panel Systems, especially if your utility has reduced or removed net metering, introduced time-of-use rates, or instituted demand charges. Installing a storage solution like the Tesla Powerwall with an ONIT solar energy system allows you to maintain a sustained power supply during the day or night, as long as you store enough power from your panels when the sun is out.


When your solar panels produce more electricity than you can use in your home, you can store the excess electricity in the battery system instead of sending it back into the grid. Later, when your panels aren’t producing enough electricity to meet your home’s needs, you can use the electricity stored in your battery instead of having to buy it from your utility company.


You NEED this whole-home battery when inclement weather cuts your power supply.


What else should you know about the Tesla Powerwall?


Behind the Powerwall’s chic white casing is one of the highest density residential and light commercial AC battery storage solutions on the market. The Powerwall 2 is a 13.5kWh capacity rechargeable lithium-ion battery that flourishes on 7kW peak and 5kW continuous power. Each Powerwall holds 12.2 kWh of usable capacity and maintains a 10% reserve so that when the power goes out, the battery has enough power to turn your solar on to get the battery recharged when the sun comes up the next day. Should there be a continuous outage, you can count on the Tesla Powerwall to have 7+ days of continuous power during an outage.


This can be installed inside or outdoors so that you don’t have to sacrifice a ton of space for the Powerwall. Check out more information by clicking here to see all of the Tesla Powerwall’s Specs.


Should you want to either live off-grid or prepare for hurricane season, the Tesla Powerwall is another excellent choice for a backup battery power supply. Be proactive rather than reactive this summer. If you have other questions about the Tesla Powerwall, we’d be happy to talk with you. Call us today to learn more at (682) 284-1174.
