Solar Power Battery Bank - Best Choice, Working and Degradation

Solar Power Battery Bank - Best Choice, Working and Degradation

Page view

Sun is among the cheapest sources of energy. The energy produced by the sun is captured by the solar panels installed in an open area. But the solar panels cannot store the electric current produced. Solar power battery banks are the ones used to store this energy for future use.

Most industries and homes now use solar power energy. But choosing the best solar battery bank is not easy without sufficient knowledge of batteries.

Choosing The Best Solar power battery Bank

To choose the best solar battery, these are various factors you need to consider;

Capacity And Power

What is capacity? Capacity is the overall amount of energy that a solar battery can store. It is measured in kilowatt (kWh). Solar batteries are stackable, meaning they are designed to include several batteries with solar-plus-storage to increase the capacity. The battery capacity indicates the size of your battery but does not tell how much electricity a battery can give out at a given time.

It would be best if you considered the power rating of your battery when making the purchase. Power rating is the total amount of electricity that a battery can deliver at a time measured in kWh. A battery with a big capacity and a low power rating gives a low electricity amount for a long time. In contrast, a battery with low capacity and a high power-rating runs an entire facility but for a short time.

Depth Of Discharge

A good number of several solar batteries should retain some charge because of their chemical composition. The solar power battery's charge should not be used to zero percent because it shortens the battery's life.

The depth of charge of a battery refers to the amount of battery's capacity used. A higher depth of discharge means you will be able to use more of your battery's capacity.

Round-trip Efficiency

The round-trip efficiency gives the amount of energy used as a percentage of the amount of energy it took to store it. For instance, if you charge your battery to 5 kWh, then use 4 kWh of the charge, then the battery has 80 percent round-trip efficiency. A higher round-trip efficiency implies a high economic value.

Battery Life And Warranty

The battery's ability to hold charge decreases as you use it. A battery might be given a warranty of 5,000 cycles or ten years at 70 percent of the original. It implies that it will have lost not more than 30 percent of its original ability to store energy at the end of the warranty.

The warranty guarantees you a certain number of cycles or years of useful life. Battery life depends on the brand of your battery and the capacity that it will lose over time.

Manufacturer

Different organizations are making different types of solar power battery banks. Therefore, when choosing a battery bank, evaluate things like the warranty given by the manufacturer.

What is the best solar power battery bank?

Batteries are made from 3 different chemical components that include: lead-acid, lithium-ion, and saltwater. The best batteries for solar are lithium-ion batteries though other batteries can be cheaper.

Lead-acid Batteries

For decades, the lead-acid batteries have been used. They have a tested technology and are used in off-grid energy systems. They are the least expensive batteries used in the home energy storage sector. The lead batteries have a relatively short life and a lower depth of discharge.

Lithium-ion Batteries

Lithium-ion batteries are lighter and compact than the lead-acid batteries. The lithium-ion batteries have a long lifespan and higher depth of discharge as compared to lead-acid batteries. Lithium-ion batteries are more expensive as compared to the rest.

Saltwater Batteries

Saltwater batteries are the most recent type of solar power battery bank in the home storage industry. Saltwater batteries do not contain heavy metals. Saltwater can be recycled after completing its lifespan, unlike the rest of the batteries. However, this type of battery is not tested yet.

How does a solar battery bank work normally?

The solar panels collect solar energy and turn it into electricity. The electric current collected is passed through an inverter then converted into a form of energy used at home. But most of the time, this energy needs to be best stored for later use.

Solar battery banks store energy collected by the solar panels for later use. Some solar batteries have their inverters, thus offering integrated conversion of energy. When the solar panels are giving out excess electricity than the required, the excess goes towards charging the battery. The electricity will be sent back to the grid when the battery is fully charged.

How long does a solar battery bank work?

There are two faces to this question. There is the time taken for a charged battery to be depleted, and the other side is the lifespan of the battery. Let us start with the first case. A fully charged battery can supply you with energy for a whole night when the solar panels produce no energy.

To know the exact amount of time taken, you need to know how much energy is consumed in your home. Also, you should know the capacity and power rating of your battery.

If you pair your battery with a solar PV array, one or two batteries can provide sufficient power during night time when solar panels produce zero energy. However, you may need three or more batteries to power the entire house for 24 hours.

Likewise, the lifespan of a solar power battery bank ranges from 5 to 15 years. Because of the recent increase in the lifespan of solar panels, it is expected that the lifespan of solar batteries will increase.

Proper maintenance of your solar power battery bank increases its lifespan. Solar batteries are mostly affected by temperature. Therefore, it is essential to protect your battery from freezing or sweltering temperatures. Many manufacturers provide a temperature moderation feature, but if your battery lacks the feature, provide an earth-sheltered enclosure.

Conclusion

With more investment in the renewable energy sector, go for the best solar power energy banks. It is now your chance to provide the cheapest electricity for your family. It is also an economical source of energy for most industries. Try solar power battery banks, and thank me later.
