The benefits of having a solar battery in your home are obvious. Solar batteries make storing large quantities of useful, clean energy in your home easy. It ensures that the lights inside stay on, even when the sun is hiding behind a layer of clouds. Many people are now electing to include solar batteries in their homes when they first install a solar panel array.
Following up from our last blog post on selecting a solar battery, the team at Palmetto thought it best to unpack some more of the thought process behind choosing the right solar battery for your home. More than just selecting one type of battery over another, there are factors about your particular home or energy use patterns that make one battery a better choice than the others.
Why Do You Need a Solar Battery?
Realistically, a solar battery is a practical addition to any solar panel installation and anyone considering adding a new solar array to their home should also factor in the purchase of a battery as well. But for those who might be hesitant to spend yet more money on a battery, here are some common reasons that many people have for owning a solar battery:
For homes that aren’t connected to a utility company, a solar battery is the only way to keep your lights and appliances running during cloudy days or at night.
By storing excess solar energy, you’re independent of your local energy grid. Not only will you have the energy you need, but also the ability to sell back any extra to the local power company, earning you money.
For urban areas that are prone to power outages, solar batteries keep your home running.
The Costs of a Solar Battery
A concern for any major addition to the home is, of course, the cost. For some, the idea of investing money in a solar panel installation only to invest more into a battery can be hard to stomach. Lucky for you, the cost of many solar batteries is starting to come down. This is in part because more manufacturers are producing batteries, and they’re improving the technology. Additionally, the same federal and state tax credits and incentives you can claim for your solar array can also be used for a solar battery.
Generally, you’ll find that solar batteries fall within a price range of $5,500 to $20,000. These prices will vary based on the size of the battery, the type of the battery, and the brand.
What Features Should You Look For in a Solar Batter?
At the end of the day, no matter what battery you choose, they should all do the same thing; store power. That said, not every battery is made the same way, and as such, they store energy differently. In order to choose the right battery for your home, you’ll want to keep these features in mind.
The Capacity of the Solar Battery
The solar battery’s capacity is the amount of energy that it can store. This storage amount is measured in kilowatt-hours. Battery capacities vary between types of battery and even within the same brand. However, some batteries are capable of being “stacked” together, which allows you to tailor how much storage capacity you have.
More than just capacity, you’ll also want to consider the battery’s power rating. Basically, this indicates how much energy your battery can make available when you need it. But striking the balance between a battery’s capacity and its power rating can be tricky sometimes. Generally, batteries with high capacities and low power ratings are good if you want to power your home for a long time, and have energy efficient appliances and fixtures. If you want to power a lot of devices in your home, you’ll want a battery with a higher power rating, but you’ll find that the capacity of these batteries is often much lower.
The Depth of Discharge
When you’re discussing the amount of energy your battery uses to maintain a charge, you’re discussing its depth of discharge. Most batteries have a suggested maximum depth of discharge that keeps them working properly. The higher the depth of discharge, the more of the battery you can use.
As an example, consider a 10 kWh battery that has a DoD of 80 percent. That means you can use 8 kWh of energy from the battery before you have to recharge it.
Every battery from every manufacturer will come with a warranty of some sort. These vary wildly across the industry, but typically, most solar batteries are covered by some kind of warranty. Most will cover the number of cycles a battery is good for before you notice a decline in performance. Others might cover a number of years of the battery’s lifespan. Within the warranty will be stipulations about the performance of the battery throughout your ownership.
