The Best Energy Storage Systems For Solar-Powered Homes
Making the switch to a new type of energy for your home can be full of decisions, but one of the best decisions you can make when installing solar energy is to look into energy storage systems. These backup batteries, allow homeowners to store excess solar energy for future use during the night and times of the year when there is less sunlight.
What to Look For In Home Batteries
The first thing anyone should look at when shopping for any kind of battery is capacity. A solar energy backup battery’s job is to store energy for later, and it follows that a battery with more capacity can power a home for longer without needing to be replenished. Other things to consider include price and warranty. Either way, the purpose of a backup battery is to make a solar-powered home more self-sustaining rather having to rely on outside sources of electricity.
Sonnen Battery Backup
Sonnen’s claim to fame when it comes to their batteries is something called “rate abitrage” - that is, the battery stores energy not only for 24-hour use and incidents like power outages, but also for when energy rates go up temporarily. For homeowners who are concerned about having an expensive energy bill, Sonnen’s backup battery could be the solution they’re looking for. It also has a guaranteed lifetime of 10,000 cycles or 10 years and a usable capacity of up to 16 kWh.
Famous for their vehicles, Tesla uses a similar lithium-ion battery for solar energy as the company does in cars. The PowerWall also comes with a 10-year warranty and has a 14 kWh capacity. Homeowners who opt for a Tesla PowerWall will be able to keep an eye on their home battery’s diagnostic through the Tesla app. This backup battery also boasts a week or more of continuous energy even during a power outage, and is entirely self-powered without using a grid.
LG Battery Backup
A popular choice worldwide, the LG Chem RESU battery currently only comes in one size in the United States - the 10kWh option - but has other sizes on the way so homeowners can choose the option best for their needs. The LG Chem RESU is also compact and known for being easy to use, as well as utilizing a unique design called lamination and stacking that extends the lifespan of the battery over time. This battery is also guaranteed for up to 10 years.
Which One Is Best?
Choosing which home energy storage system is best for your solar-powered home can be a confusing decision. Homeowners may be concerned about price, which option will save money in the long run, and which batteries will be able to keep their homes running efficiently, rain or shine.
