Pros And Cons of Solar Battery Storage

Have you been thinking about putting solar panels on your roof in 2022? If so, the issue of solar batteries for electricity storage has likely come to your attention. Pairing enough battery storage to match the capacity of solar panels on your roof has become much more popular because of the blackouts and outages of recent years. It might seem odd, but when people think of solar panels on their roof, they usually don't think of on-premise electricity storage - a battery bank to hold the power your rooftop panels produced during the sunlight hours.
To get a complete picture of how the more efficient batteries of 2022 fit into the overall solar system, it would be helpful if you understood how a solar array system generates the power you can use. A solar panel array on your roof captures the direct sunlight and converts it into DC (Direct Current) electricity. Then the array hands off this DC electricity to an electrical inverter, changing it from DC (Direct Current) to AC (Alternating Current) electricity. Your home uses alternating current.

Correctly designed solar systems produce more electricity than the home can use during the daytime. When a solar system creates more power than you need, it can handle the excess in two ways, depending on your solar system setup. First, it can send the extra electricity back into the grid, and your neighbors or anyone else on that service can use it. Alternatively, it can send it to a battery bank that you own and is on your property.

If your system configuration sends it back to the power grid and your area has net metering, you will get to use that electricity later. Periods of low or nonexistent light would be during the night or periods of shade, when your solar panels are not producing enough electricity for your needs.
Well, it turns out there's another option for storing that excess electricity. If you include a battery backup in your solar system configuration, you won’t need to send that extra power back to the utility. You can keep that electricity in your house by storing it in your very own battery bank.
As battery technology has progressed and the price for storage drops, there's another option for storing that excess power that you produced during the sunshine hours. It won't be necessary to send that extra power back to the utility if you include a battery backup in your solar system configuration. Instead, you can keep that electricity in your house by storing it in your battery bank.

As we all know, solar panels have become an outstanding option for producing the electricity we use in our homes. Modern solar batteries allow you to store the extra electricity you create during the daytime to be used at night or during extended low sunlight days. When a solar system on a roof includes a battery storage component, we refer to that solar system as a”
hybrid solar system,” 

There are a number of advantages to having a hybrid solar system. The two most common are:
1. You can store the electricity your solar panels have produced for later use.
2. Batteries can provide you with independence from the power company during any electrical grid outages or other grid problems.
The big question is, "Are solar batteries necessary, and how do they work?" The equally big question is, how much do solar batteries cost? This is a decision you will need to answer. Fortunately, we cover that in this article.

Because solar panels only work when the sun is shining, they can't provide any electricity during the night. They also might not provide sufficient electricity during extended periods of heavy cloud cover.

It might surprise you that they are not allowed to produce any electricity when there is a blackout. Adding solar batteries to your solar panel configuration provides a way to produce extra electricity for use during these power outages.

Solar panels are only able to generate electricity when the sun is shining. This means that they cannot provide power at night or during extended periods of heavy cloud cover. However, you can install solar batteries to your solar panel configuration in order to have a backup power source for times when the electricity is out.

Solar panels on your roof convert the majority of the electricity in the middle of the day. Unfortunately, that coincides with the time many homes have their lowest demand for electricity. For solar systems without a battery backup, the traditional method of storing the extra electricity is to send it back into the utility grid. Your smart meter on your house keeps track of the amount that you send back and with net metering, you will get credit for that electricity.

You will be able to use it at a later date by drawing it back from the utility or alternatively, the utility will credit your monthly bill for the amount that they receive. Essentially, the power company's grid acts as a huge battery where you can store your excess electricity. Of course, this kind of storage is not available when the grid goes down during an electricity outage.

If you have battery backup paired with your solar system, the extra electricity that you produce will be deposited into the battery bank instead of being sent back to the grid. When the sun is not shining on your panels, for instance at night time, solar panels won't produce any more electricity. This is the time that you can draw the electricity you have stored in your battery instead of getting that electricity from the utility.

If you have solar batteries for your home, you get to take advantage of the solar generated electricity to power your house any time of the day or night.

WILL SOLAR BATTERIES LET ME HAVE ELECTRICITY DURING A BLACKOUT?

Everybody in the United States remembers the disastrous widespread blackouts in Texas in early 2021. Projections for blackouts are not encouraging. In some areas of the country, the grid is expected to have great difficulty in the not-to-distant future. A solar panel system paired with a whole-house backup battery bank can be the solution to having power during a widespread outage.

There are two considerations when discussing having power during a blackout when you have solar panels on your roof.

The first consideration is that most solar panel systems automatically disconnect from the grid when there is a power outage. It’s a requirement in all states. The reason for this is so that utility line workers working on repairs expect the grid to be without power. If your solar panels are charging the grid, the workers may be injured or killed by the electricity from your panels.

There is a workaround that allows you to use your home-grown electricity during a power outage and not endanger power utility workers. You can have a special switch installed on your solar system that disconnects your system in the event of an outage.

The second consideration is that you need sufficient battery backup to store all of the electricity you would need to use when the sun is not shining. Typical solar panel systems draw electricity from the utility grid but if the grid is down that's not possible. If it is your goal to be entirely energy-independent and be able to operate “off-grid”, you will need sufficient capacity in a battery backup.

To find out just how much battery capacity you need, you can ask your solar provider to do an energy audit on your home. When sizing your backup battery capacity, you may want to consider what electrical appliances and systems are essential. Batteries are expensive.
One way to reduce the cost of the battery backup system is to only plan to have essential appliances operational during a blackout. These types of essential appliances would include a refrigerator, a freezer, any medical devices, and anything that you absolutely need in your house to run during a blackout.
WHY DOESN’T EVERYONE GET SOLAR BATTERIES?

If batteries were free, everyone would load up on solar battery capacity - but batteries are expensive. While there are several different battery technologies for solar backup, the most commonly used in residential systems are lithium-ion batteries.

Battery technology has advanced significantly in the last few years, but in 2021, the cost of battery storage can add between a few hundred dollars up to $15,000 - depending on the type and amount of battery storage. For example, according to Forbes the cost of Tesla Powerwall is around $6,500 and a Costco battery may not be as nice but could cost less.

Fortunately, solar batteries are considered part of the solar panel system by the federal government and are eligible for the federal solar tax credit of 26%. Additionally, many states have tax incentives programs that promote battery storage on solar panel systems to help take away the sting of buying batteries.

SHOULD YOU INVEST IN SOLAR STORAGE
When deciding what kind of storage option you should get for your solar system, these are some of the questions to ask:

COSTS: Pricing for the battery bank storage system for storing excess solar-generated electricity.

A price and configuration proposal for a residential solar system includes a variety of factors. The most important is how much electricity your home needs. Also considered is the size of your home, the available roof space, the orientation of your roof, how many hours of direct sunlight, and how many solar panels you should install. 

Solar systems pricing varies across the United States and can range between $10,000 to $70,000. The overall cost would depend on the size of the system, the battery backup storage and the tax credits for which your home qualifies.

FINANCING: What are my solar financing options?

There are a variety of federal and state programs to give homeowners a hand in going solar. The biggest tax rebate is the federal rebate Investment Tax Credit (ITC) which in 2021 is set at 26% of the cost of your system. Fortunately, this 26% can be applied to battery storage as well as the solar panels.

You may also be eligible for PACE financing Property Assessed Clean Energy (PACE) is a program that is designed to help homeowners pay for energy-efficient upgrades, renewable energy (Solar), conserve water, and protect against storms

According to www.energy.gov. “The property assessed clean energy (PACE) model is an innovative mechanism for financing energy efficiency and renewable energy improvements on private property.” There are several agents who can provide you with assistance with PACE (such as https://ygrene.com)


QUESTIONS TO CONSIDER ABOUT STORAGE BATTERIES

MAINTENANCE: What kind of maintenance will my batteries need and how much will that cost?
LONGEVITY: What is the expected lifetime of the batteries and what warranties come with them?
ELECTRICITY SAVINGS: How much will I save on electricity because I can store my own excess power?
EMERGENCY PERFORMANCE: In case of a widespread outage, how well will my battery capacity power my home over a long period?

CONCLUSION: BATTERY BANK STORAGE FOR SOLAR PANELS

Solar panels have become very popular especially with their prices dropping. They provide security during widespread power outages. When getting a price for a solar system for your home, consider the secondary systems that you might want to have in order to reach your electricity and security goals.

In the case of a solar system with a robust battery backup bank, ask yourself if the peace of mind knowing you will have electricity during a lengthy widespread power outage is worth the cost.
