Things to Keep in Mind When Comparing Solar Battery Prices

Energy storage systems like solar batteries provide several benefits, from emergency power backup to cost savings; however, due to their complex terminology, people usually find solar batteries hard to understand.

So, to make it accessible, here are the key things you need to keep in mind when buying a solar battery:

1. Power Rating

The power rating of a solar battery refers to the kilowatt of power that it can provide at one time. In other words, the power rating shows both: the number of appliances the battery can handle at once and which are those appliances.

Different appliances use a different amount of power. For example, a lightbulb uses 12 watts of power, a 3-ton AC consumes about 4.8 kW, and so on. Power rating is an important factor to consider apart from the solar battery price.

2. Battery Storage Capacity

The storage capacity of a solar battery is the amount of electricity that it can store and supply to your house. The battery storage capacity simply tells you how long the solar battery can power your house. Therefore, make sure to check the battery capacity as it represents the amount of electricity stored that you can access during emergencies.

3. Efficiency

Efficiency is a metric that measures how well the solar battery system converts and stores electricity. There are always losses with an electrical process, which means that you will lose some electricity while converting it from Direct Current (DC) to Alternating Current (AC). The efficiency of a solar battery tells how many units of electricity you can get out of every unit of electricity you put into it.

4. Battery Life and Warranty

The battery life is another important factor to consider other than the solar battery price. Make sure that the battery you buy provides a long warranty. The warranty period of a solar battery is usually specified in terms of the number of charging and draining cycles it can endure, or the years it will function.

5. Depth of Discharge

Depth of discharge is the measure of the battery capacity that can be used. Manufacturers specify this metric because the battery needs to retain some charge at all times to provide efficient and optimal performance. This is a vital factor you should consider other than the solar battery price.

6. Safety

A solar battery must meet certain safety requirements. The safety of a solar battery is determined by its performance at high temperatures. The best solar battery performs well at all temperatures. Apart from the solar battery price, safety is one of the most significant factors that must not be overlooked.


7. Chemistry

The chemistry of the solar battery is the primary compound that is used to store electricity. It may be the most important characteristic to consider other than the solar battery price. The solar batteries with different chemistries come at significantly different price points, so make sure to choose a battery with a composition that fulfils your power requirements.

8. Brand

The lifespan and warranty of the solar battery depend on the brand. Make sure to buy the battery from a reputed brand to get a battery that provides sufficient capacity and optimal power backup in times of need.

Make sure to keep the above factors in mind when comparing solar battery prices, as investing in high-grade solar batteries can continue to benefit you for many years to come.

How Does a Solar Battery Storage Work?

The idea of having an energy-independent home is quite enticing for any homeowner. It comes with a lot of advantages, the main one being the fact that you won’t be affected by utility rate fluctuations. Also, you’ll be promoting the ‘green energy’ campaign, which is currently being recommended as a way of preserving the environment. Fortunately, it’s an attainable dream given the rapid advancement in the world of energy storage. All you need is a set of solar panels or a solar energy provider, and a battery backup to satisfy your needs.

Solar batteries are an integral part of this setup since they ensure a continuous supply of power if the grid goes down. This article will break down the seemingly complex operation of these storage devices into a few easy-to-understand steps. The discussion will revolve around a battery that’s already paired with a solar system rather than a standalone solar battery storage.


Feeding the Solar Energy

When sunlight rays hit the panels, the visible light is converted to electrical energy. The electrical current flows into the battery and is stored as DC electricity. It’s worth noting that there are two types of solar batteries: AC-coupled and DC-coupled. The latter has a built-in inverter that can convert the electricity current to DC or AC. As such, the DC solar electricity will flow from the panels to an external power inverter, which will convert it to AC energy that can either be used by your home appliances or stored in the AC battery. What the built-in inverter will do in this case is convert the AC electricity back to DC for storage.

As for a DC-coupled system, the battery doesn’t have a built-in inverter. As such, the DC electricity from the solar panels flows to the battery via a charge controller. Unlike in an AC setup, the power inverter in this system is only connected to your home’s wiring. As such, electricity from the solar panels or your storage battery is converted from DC to AC before flowing to your home appliances. What determines how much energy is stored in the battery?  Read on to find out more.

The Charging Process

As power flows from the solar panels, your home’s electricity setup will take precedence. Therefore, electricity directly feeds your appliances, like refrigerators, TVs, and lights. Often, this energy from solar panels can be more than what you need. For instance, on a hot afternoon, a lot of power is produced, yet your home isn’t using much of it. In such a scenario, net metering occurs, wherein the extra energy flows back to the grid. However, you can use this overflow to charge up your batteries.


The amount of electricity stored in the battery depends on how fast it charges up. If, for example, your home doesn’t use up too much power, then the charging process will be quick. Also, if you’re connected to huge panels, then a lot of electric energy will flow to your home, which means the batteries will charge up a lot faster. Once your battery is full, the charge controller will prevent it from overcharging.

If you are actively looking towards the idea of having clean, free energy, but don’t have enough money to invest in solar panels, you should definitely consider buying a solar generator. Solar generators utilize solar panels, capturing the sun’s energy. The solar energy is stored in a batter. A solar generator has four components, including the solar panels, controller, inverter, and solar battery.

Solar generators don’t require fuel to work—all you need to do is set up the solar panel, and you’ll benefit from clean, renewable energy. Because solar generators don’t release pollutants, you can safeguard your family’s health and protect the environment. Solar generators are highly preferred over traditional generators because they’re quiet, low-maintenance, and cost-effective.

Why Do You Need A Solar Battery?

Homeowners can use Plico Energy’s solar calculator or any similar online tool to determine how much solar energy they need. But even if you have a rough idea of the amount of solar power you need to sustain your daily tasks, it’s still important to buy a solar battery. Here are some of the reasons why you should invest in a solar battery:

1. To shield you from power outages

If you’re connected to a grid, there’ll always be a few moments when the transmission system malfunctions or is shut down for maintenance. As soon as this happens, the system will isolate your home from the grid and activate the backup source. In this case, the battery will operate like a backup generator.

Having backup power through solar batteries can prevent the inconveniences associated with outages. Hence, you can continue using your appliances for household chores, entertainment, studying, or working at home. Most of all, if you have a sick family member needing a piece of medical equipment, such as an oxygen tank or a respirator, you won’t face problems with sourcing a generator or a power backup.

2. Time-of-use rate plans

On these plans, you’ll be charged according to the amount of electricity you use, as well as the time during which you use it. TOU states that the power drawn from the grid at night is more valuable than the extra energy produced during the day. As such, by storing the extra energy and using it at night, you’ll reduce the overall cost of electricity in your home.

Governments around the world are recognising the benefits of solar batteries. So much so, that they are offering rebates for homeowners to help with the upfront cost of buying a solar battery. These rebates for solar batteries are becoming more and more popular and are a sign of the huge benefits batteries provide to homeowners and the world. Solar battery rebates are helping to promote the adoption of solar energy systems in many countries.

Closing Remarks

With the world embracing ‘green energy,’ solar panels are gradually replacing the traditional sources of electricity. Solar batteries play a crucial role in ensuring that you have a reliable power supply in your home. AC-couple storage batteries have a built-in inverter, which converts the electric current to DC or AC, depending on the direction.

On the other hand, a DC-couple battery doesn’t have this feature. Both batteries, however, store electric energy in DC regardless of the setup. The speed at which electricity is stored in the batteries depends on the size of the panels and the amount used by your home appliances.
