Why Should Add A Battery Backup to a Solar?

Lithium Ion Batteries features

The basic structural chemistry of these batteries consists of nickel-manganese-cobalt, lithium polymer, and lithium iron phosphate. The advantage of using this type of battery is that it reduces the risk of catching fire. Moreover, their one charging cycle is longer than any other battery.

The degradation of the stored energy is very rare in these batteries. You can easily use 90% store energy of Lithium batteries.So they are suitable for residential use. However, these batteries are expensive and prone to degradation in extreme hot temperatures.

Lead-acid batteries Features

This type of battery’s prominent feature is that it is acid-sealed and reduces the risk of acid spillage during maintenance. They are less costly and easily available in the market. However, they can not meet the Lithium-ion batteries in energy efficiency. They are also usable for the residential projects due to low prices.

Nickel-cadmium batteries Features

Their working capacity is above all other batteries because they are made up of lead and acid. These batteries are durable, have long life cycles, and require less maintenance. They are widely used in industrial and commercial projects.

Flow Batteries

These batteries are less effective for residential use because their structure is designed to be suitable for commercial use. However, the manufacturers are also planning to make it effective for residential use.

Batteries backup energy for your needy times such as dawn and dusk, stormy days and rainy weather. You can use battery backup energy according to your need. Moreover, at the time of local grid outage, you have a secure backup system for the power supply for your home.

Batteries allow you to go completely out of connection from the grid. But this depends upon the size of your backup system and the daily use of your home. Batteries are a primary storage option in those areas of the USA, where local utilities offer very low rates for net metering, or there is no net metering.

Some people think that battery backup is unnecessary when installing a solar system and also remaining connected to the grid. Are battery backups necessary only when opting for off-grid solar installation? If yes, then you are not right. Let’s make it clear to you.

Suppose you have a grid-tied solar system and a grid outage in your area. The solar system will automatically shut down during a grid outage, and there will be no power at your home. The two disadvantages of grid-tied solar systems without battery backups are

• • You can not send the excess energy of the solar system to the grid at grid shutdown time.
  • The grid is down, so you can not use the energy that you have already sent to the grid, and there will be a complete blackout at your home

To avoid these scenarios, battery backups are the best option.
So, whether you plan to do grid-tied solar installation or without grid-tied solar installation, batteries attached to the solar system are great investments.

The demand for battery backups is increasing day by day. This is because utility companies are enhancing power supply prices. It is a very good decision if you are also planning to connect a battery backup with your system. There are some factors that you should consider while thinking about the battery installation such as

Although various incentives and rebates are available for battery installation, the prices are still high. Batteries are considered a one-time investment, and you should choose them carefully. Before purchasing a solar system, you must consider the following essential factors.

Energy Needs

Daily energy needs are the prime factor to consider when buying a battery for your home. You can analyze your daily energy consumption by reading daily utility units from your meter or your monthly electricity consumption through your monthly bills. This will help determine which power (KW) battery can meet your home needs.

Grid Outage Rate in Your Area

If you live in a state where grid blackout days are standard and remain for days, you must have more batteries to become entirely energy-independent. However, if the rate of grid shutdown is rare, you can go for fewer batteries.

Lifespan of Batteries

Solar batteries usually last 3-15 years. If you buy a battery of low quality, you may spend more money on maintenance or even have to buy a new battery after a few years. So, always try to buy a high-quality battery from a reputable and trustworthy manufacturer.

Batteries Types

Batteries may be sealed or flooded. Sealed batteries have their electrolytes in a stable gel or electrolytes, while flooded ones are open with portable caps. You have to open the caps and fill the distilled water within the batteries. According to safety measures, sealed batteries are more secure, but they are a little bit expensive compared to flooded ones.

Warranty of the Batteries

Over time, the battery loses its capacity to hold a charge, and efficiency decreases. The average warranty of batteries from reputable manufacturers is ten years. Always try to purchase a battery from a manufacturer who is assured about the warranty.

Batteries Vs. Solar Systems Size

The size of the solar system is directly linked to the selection of the batteries. If you have a larger-sized solar system that produces a hefty amount of surplus energy, larger batteries are required to save the energy. For example, a typical 5KW solar system is sufficient to charge one battery after fulfilling your home needs.

Voltage of Battery and Inverter

The voltage of the battery and inverter should be the same for the proper working.

Incentives and Tax Reduction in Your Area

Incentives and batteries can reduce the initial cost of the solar system. Usually, the Federal tax credit, which is almost 30%, is applicable in all states. Various areas offer local incentives and rebates for battery purchases. Moreover, many manufacturers offer special discounts for battery purchases on specific occasions.

Therefore, research regional incentives and rebates for the batteries, check the rates for various manufacturers in your area and then purchase from the manufacturer that offers a more suitable priceood decision if you are also planning to connect a battery backup with your system.

Although various incentives and rebates are availaThis is also a very important consideration to save your home and loved ones from any potential hazards when installing batteries at home.

According to the National Fire Protection Association (NFPA), all individuals must follow the NFPA 855 Standard for installing Stationary Energy Storage Systems. This act states that all solar systems ranging from 5 kW TO 20 KW come under residential setup, and the residents can install them in their garage, utility rooms, or any room in the house. If you plan to place the battery in the room, your walls should be protected by fire-proof sheets such as gypsum.

What to consider when choosing a battery location

• It would help if you considered some important factors when choosing a solar battery location for a residential place.
• If you live in an area with high rainfall annually, do not put the battery outdoors.
• Batteries are easily degradable by high temperatures. So, make sure that the sun does not hit the batteries.
• If you are living in an area near the sea, then never place your battery outdoors because it can generate current.
• Always select a location where the movement of the house residents is less, such as a store room or the utility room.
• Some batteries are very heavy to install. So, always call a professional engineer who will inspect your home and select the place suitable for the heavyweight batteries.
• Batteries get hot and emit glass, so there should be proper ventilation to avoid the accumulation of gasses and any loss.
• If you have more than two batteries, maintain a three-foot distance among all batteries.
• Always choose a location that is easily accessible to avoid any hurdle for maintenance.

Never place the battery with any combustible material. If your house has a woody structure then place a non-combustible floor mat on before placing the battery.ble for battery installation, the prices are still high. Batteries are considered a one-time investment, and you should choose them carefully. Before purchasing a solar system, you must consider the following essential factors.

The cost of the battery is 8500$ to 10,000$. This cost is without installation charges.

Besides installation, some other additional charges, such as a permit to install batteries and connect your battery to the grid system, can affect the overall cost of the solar system. Moreover, battery cost depends upon the capacity and the size of the battery.

Do you want to add battery backup for your existing grid-tied solar system? Well, this is possible but expensive. The connection of the battery with the existing grid-tied system is known as AC-coupled battery backup.

In this process, an additional inverter is attached to the solar system because your existing inverter does not produce the power for battery backup when the grid is out.

Yes, you can use solar panels without a solar battery. Many homeowners need batteries to start using solar systems.

However, having battery backups is beneficial because it makes you self-sufficient for your energy needs, and you do not need to worry about the continuously changing net metering laws and prices in the country. Let’s discuss the advantages of battery backups.

Do you ever wonder why I need a battery for my solar system when I already use the sun’s renewable green energy? Well, if your solar system produces more power than your daily use, what should you do with it? Yes, you can send it to the grid for net metering.

But does this net metering benefit you on cloudy days when local grids fall for days? No, net metering will not help you in this scenario. So, it is better to have a solar system with battery backup to save your energy by yourself instead of sending it to the grid. This will make you energy-independent 24/7/365.
Having batteries with your solar system helps you in many ways. Following are the few prominent benefits of battery backups.

1.Energy Independent

The batteries store the energy for your backup needs, and you can use this energy at any time. This eliminates your dependency on the grid system for the power supply. Moreover, you can use this energy on cloudy days and at night.

2.Get Rid of Electricity Bills

Completely relying on the battery backup is a very good option because it helps you to be free from the tensions of the increased electricity prices. No supply from the grid, so there is no need to worry about the electricity bills.

3.Real Monitoring for Your Daily Use

With the battery backup and its integration with the apps, the solar system allows you to monitor your production and usage simultaneously. For example, you can monitor and use heavy-voltage appliances when there is more energy production.

Batteries are a great source of energy independence.They store excessive energy and you can produce sufficient energy for your usage. The average cost for the battery installation is 8500$ to 10,000$. Battery backups are very good sources of independent and self-sufficient energy.

You can also install the battery backup for your existing solar system. However, it would help if you considered a few factors, such as the suitability of the solar panels for battery integration, rewiring for battery and new inverter connections, battery location, and regulatory compliance in your area. Moreover, analyzing your daily needs and energy-sufficient requirements are other important factors before purchasing a solar battery.
