Hello World! Welcome Friends! Over time, solar systems have overcome many challenges, and improvements have been made to ensure that the designs are efficient and reliable.
For instance, since solar is dependent on the sun, it might seem like you will face challenges when the weather is cloudy.
Fortunately, by having solar battery backup for home use, you can overcome this challenge. Here’s what you need to know about solar battery backup systems.
How Do Renewable Battery Backups Work?
In the early stages of solar, a system known as net metering was put in place. With a net-metered solar panel, the excess energy generated by your solar panels will go into the grid.
This energy would then be used to offset your electricity bills during those times when your system wouldn’t be producing enough electricity for your needs. Instead of electricity going back into the grid, a solar battery for home use receives the extra electricity from your solar system.
After the sun has gone down and your solar is no longer generating power, your home will then start drawing energy from the battery backup power supply for home setups instead of the grid to power things like your Tesla charger installation.
Advantages of Solar Power Battery Storage Systems
Here are some advantages of battery storage for home purposes:
Reliable Backup
As mentioned before, the previous challenge of ground-mount solar panel installation without backup batteries is that you can only generate energy when the sun is up and shining.
This means that at night or during cloudy weather, you’d have to return to drawing energy from the grid. Solar panel backup batteries solve this issue.
It essentially harnesses energy when the sun is up and makes that energy available during the times when your solar system can not generate enough power for your home. This is one of the most significant benefits of solar energy storage.
Lower Utility Rates
This one is almost a no-brainer. By having storage batteries for solar systems, your home will become less dependent on the grid.
Even when your solar is not producing enough energy, you can still power your home or at least part of it using a battery backup.
This means your home will rarely draw all its electricity from the grid. As you might imagine, that will greatly lower your utility costs.
Should You Get Battery Storage for Your Solar Energy System?
The short answer is YES. While a set of solar panels without a backup system will function normally, you can’t rely on it entirely. During conditions when your solar panels can not generate electricity, your only option will be the grid. This means every night, you will go back to using electricity generated from fossil fuels. A battery backup allows you to fully take advantage of your home’s solar system.
What Will It Cost?
The solar battery storage system cost depends on the size and battery chemistry.
According to Market Watch, prices range from $200 to several thousands of dollars.
You can even get some backups that cost as much as $25,000 to install. Most homes use lithium-ion batteries, which cost anywhere between $7,000 to $14,000.
The good thing about solar batteries nowadays is you can offset your costs through the 26% federal solar tax credit.
You can be lucky to find out you are in a state that has added solar battery incentives on top of the solar tax credit.
How Long Can You Run Your Home on a Solar Battery Backup?
This generally depends on the size of your battery backup and the size of your home as well. Most good backup systems can power your home for about 12 hours. There are some really good ones that can power your house for up to 15 hours.
Five Tips on How to Choose a Good Solar Battery
Solar battery backup systems are great for homes, but you need to keep in mind that not all of them are created the same.
This means you need to know how to choose a good battery that will serve you well. Here are some tips to consider:
- Buy from a reputable brand. You should also check reviews to find out about the best brands for solar batteries.
- Get a battery with a good warranty. Any good brand stands behind its products. Never buy a battery without a warranty.
- Check the ambient temperature rating. This is the temperature where a particular battery gives peak performance. It should be in line with the weather in your area.
- Choose batteries with a higher round-trip efficiency. These are more efficient and economical.
- Check the battery capacity and ensure it matches the needs of your home.
Summing Up
Having a solar battery bank for home ensures that you have power even when your solar panels aren’t generating any.
However, to get the most from your backup batteries, you should first find out your home’s needs and ensure that you get a backup that has the output to match your needs.
