Solar Batteries – Frequently Asked Questions

1. What does a battery storage system look like?

The size of a battery storage system depends on the commercial and household units in which it is installed. The battery storage system, which is primarily for households, is the size of a small refrigerator. Battery storage systems in business settings, on the other hand, can be rather substantial. Commercial solar batteries can be as big as a large refrigerator or a 20-foot shipping container.

2. How does a battery storage system work?

The chemical processes happening inside the battery aid in storing electrical energy. The electrical system then uses this energy to brighten the residential or business setting.

3. Are Solar Batteries Worth It?

Solar batteries are a fantastic complement to any solar power system. Batteries, on the other hand, usually have a more extended payback period. However, a battery-powered solar system can help you completely eliminate or drastically cut your electricity expenditures. It can also assist you in lighting your home during a blackout and reducing your carbon footprint. Read our previous blog, “Why solar batteries are a long-term investment?” to enlighten yourself regarding the benefits of solar batteries.

4. What is a battery “cycle”?

One cycle is defined as a full-power charge and discharge.

5. What are the benefits of battery storage?

In the solar sector, the battery is a fantastic breakthrough. It gives end-users additional control over the system. Many advantages are available to battery users, including increased energy savings. Being independent of the grid, especially during peak hours when grid rates are pretty high. Even during outages, the battery continues to function.

6. Is battery storage and a residential ESS (Energy Storage System) safe?

Yes, it has the potential to be safe, but it also has some risks, just like any other electrical system. Some precautions should be taken to keep hazards to a minimum. It is very important to find a reputable solar contractor who should install the system appropriately.

7. Can my solar battery be outside?

This is dependent on the system or technology that your battery employs; if you plan to install your battery outside the house. Please contact our battery experts to ask for advice.

8. What types of battery storage are available, and which is the best?

It is an important question to ask when buying a battery. However, lead-acid and lithium-ion batteries are the most frequent options. Nickel-cadmium, nickel-metal hydride, and flow batteries are some of the less popular alternatives. You can learn more about buying the best solar battery storage in our previous blog, “How to Buy the Best Solar Battery Storage?“.

9. Can I go off-grid?

The short answer is yes; however, there are some reasons we don’t recommend clients to do so. Bad weather reduces the supply, and the battery may not be able to meet your demand on cloudy days. Connecting to the grid will also allow you to sell any excess electricity to the grid.

10. How long will the solar backup batteries last?

The brand’s technology determines the lifespan of solar batteries. Solar batteries typically have a lifespan of 5 to 15 years. It means that the battery life is shorter than that of the solar panels. However, as the solar industry’s technology advances, the life of the panels and batteries is also increasing over time.

11. What is the most significant factor that impacts battery life?

The temperature has a considerable impact on the battery’s life. As a result, maintaining an appropriate enclosure to protect the batteries from overheating is critical. There should be adequate cooling to avoid overheating and adequate protection during periods of extreme cold. When the battery temperature falls below 30 degrees Fahrenheit, more voltage is required to charge the battery. When the battery temperature rises above 90 degrees Fahrenheit, however, the battery can overheat and require a charge reduction. Temperature moderation is a feature provided by battery manufacturers to address this issue. When purchasing a battery, finding a reputable manufacturer and installer is critical.

12. How long can a solar battery power my home?

It’s a thorny issue that is influenced by several things. It largely relies on your household or commercial consumption, the load your battery can handle, and whether you have a battery and grid or an all off-the-grid solution. Some additional factors can affect the battery’s performance and total life; if your usage exceeds the capacity of the battery, you may need more than one battery.

13. Can I run my house on solar battery backup power only?

Yes, you are capable of doing so, but it is not that easy. It requires a proper design, and it is dependent on your usage, photovoltaic generation, and the type of battery utilized.

14. How much would it cost to run on solar battery only?

Many factors determine the exact cost. These parameters include your energy consumption, battery manufacturer, solar energy system size, kind, as well as the quantity of daylight available. Read our blog “What determines the cost of a solar battery?” to know more about the factors that determine the cost of solar batteries. There are also government rebates available for people who want to go solar and install a battery system. Our experts can help you with getting the government rebates.

15. How do I size my battery system?

The battery systems are measured in kilowatt-hours (kWh) (kilowatt-hours). If the average home consumes 20kWh per day, you’ll need a system that can handle 30% of that during the day and 70% at night. As a result, 6kWh is used during the day, and 14kWh is used at night. As a result, you’ll need a battery that can provide 14kWh of nighttime usage on average.

16. When the grid goes down, will the batteries continue to work?

Yes, but only if the battery has an “islanding” capability. When your system has islanding capacity, it won’t send any electricity into the grid during a blackout, and all remaining power will go to your loads.

17. Can I be power bill free with a solar battery?

If the size of your solar battery and solar panels is right for your usage, you have the chance to lower your bill to zero or extremely low.

18. Can I monitor the solar battery?

Many solar battery installers will provide you with battery management software and apps that will help you to increase your power independence by monitoring the system yourself.

19. Can I add a battery to my existing solar system?

Yes, the system can be extended as long as meeting local electricity network requirements. And we can provide a solution. Contact us, and we will connect you with our experts who can help you with their expertise.

20. Can I increase my battery storage capacity in the future?

Yes, you may always upgrade your existing solar system’s battery capacity. However, you must determine whether your solar system is capable of charging this new battery or whether you require additional solar panels. You can learn the solution to this question by reading our blog, “The most crucial question: more solar panels or a battery?”.

What is Solar Inverter Oversizing?

By Lisha Ouyang • 01 Aug, 2023

Normally the number of solar panels installed on the roof is matched to the solar inverter size. The total number of panels is calculated by dividing the inverter power rating by the chosen solar panel power. This was often the practice carried out by some solar designers in the past. If you have been in the solar industry, you probably heard of the idea of “inverter oversizing“.

Frequently Asked Questions About Using Solar Power for Winter Energy Needs

By Lisha Ouyang • 19 Apr, 2023

1. Do solar panels work in the winter? Yes, solar panels do work in the winter. It doesn’t matter how hot or cold it is. In fact, they can be more efficient in colder temperatures as long as they receive adequate sunlight. 2. Will snow cover affect my solar panels’ performance? Snow can affect solar panel performance if it covers the panels completely, but most modern solar panels are designed to be self-cleaning and will shed snow and ice on their own. Even a small amount of sunlight can generate enough heat to warm up a solar panel and help it in melting the snow. This is because solar panels are designed to absorb sunlight and convert it into energy. As they absorb sunlight, they also absorb heat, which can help raise their temperature and melt any snow or ice that may have accumulated on them. Additionally, snow can reflect sunlight back onto the panels, which can increase their output. 3. How much energy can I expect my solar panels to produce in the winter? The amount of energy your solar panels produce in the winter will depend on factors such as location, weather conditions, and the angle and orientation of your panels. However, in general, you can expect your panels to produce less energy in the winter than they would during the summer months. 4. Do I need to make any adjustments to my solar panel system for winter? In most cases, you do not need to make any major adjustments to your solar panel system for winter. However, you may want to clear any snow or debris from around your panels to maximize their exposure to sunlight. 5. Can I still use solar power during a winter power outage? Yes, if you have a solar power system with a battery backup, you can still use solar power during a winter power outage. However, if your solar panels are grid-tied and do not have a battery backup, they will not provide power during a blackout. 6. Will my energy bills be lower if I use solar power in the winter? Your energy bills may be lower if you use solar power in the winter as long as your solar panels are generating enough energy to meet your household’s needs.

Part 2: Going Solar! Stay Aware of These Traps!

By Lisha Ouyang • 04 Apr, 2023

Going Solar is the most beautiful gift you can give to mother Earth. But you can fall into many traps if you don’t know how to do it effectively. This Blog is the sequel to the previous blog . We recommend reading it before starting this blog if you have not checked it out yet. 6: Believing! If the location is not optimal, the Solar is not worth it. It is a big one among the many traps! If the location is not optimal, the solar system is not worth it. It has been claimed recently that solar systems are getting better with time. And in today’s time, even if the solar panel is not installed in the north direction, it would still be worth it. As you only lose 10-15% of your solar system production. This depicts that even though the location might not seem right to you going, solar is still a fantastic decision that can help you save a lot in the long run. 7: Settling for DIY solar systems Solar systems can vary in size and the way they operate. Some people can go for off-grid plug-and-play solar systems, which are not very complex in their operations. These DIY solar systems also aid you in going solar, but you cannot completely go off the grid with these systems. Hence, if the person’s goal is to get self-sufficient in electricity, they should think of installing the solar system through a reliable service provider. Otherwise, a person can fall into the trap of wasting money on getting a system that is not fulfilling the energy demands fully. 8: Making the decision solely based on the price Going Solar is a tremendous decision, and it can look like an extravagant purchase. Some people can make the mistake of going for the company that is offering the least money. The money factor can add to the traps section when going solar. You can choose a company offering you the least amount, but the system being delivered is also very substandard. Although it has not been advocated here that the cheapest is the worst. But while deciding to go solar, look for company ratings, reviews, and how they deal with your needs before the purchase. The value for money should be considered before deciding to go solar with any company. The company that provides the best value for money should be chosen. 9: Not Taking Advantage of Incentives Solar can help you make the environment more sustainable and can also assist you in gaining incentives from the government. It is essential to have a hold on the knowledge of incentives that the government is offering to achieve the maximum benefit. A prevalent perk the government provides is lowering taxes for solar energy-dependent individuals. And businesses can benefit by capitalizing on accelerated depreciation. It is vital to keep yourself up to date with what the government is offering in terms of the benefits for the solar community. 10: Lack of knowledge of Warranties It is vital to know warranties before going solar with any installer. There are two types of warranties. One is offered by the manufacturer, and the other by the solar installer. Sometimes the manufacturer only gives a warranty. So if something happens with the system, the customers are satisfied that it is still under warranty. They can get it fixed without any cost. But they are actually falling into one of the traps! When they ask the installer to fix it, the installer doesn’t take charges for the system, but the installer does charge for the labor work. So it is crucial to know what the manufacturer is offering you as a warranty and what is being communicated to you by the installer. It is better to go with an installer that can also cover the labor charges in the warranty.
