Know your best power saver; Solar vs. Normal batteries

Future is electric, the importance of batteries are also levelling up. In this scenario where world is running with the technology, it’s essential for each one of us to choose the best option for power backup.

The energy from a solar PV system is normally stored in a solar battery. The solar panel converts the energy from the sun into electricity, which is then sent from the inverter to your house for use. The PV system is connected to the electrical grid in the event that you don’t have an off-grid solution. If the solar panels aren’t producing enough electricity to meet the demand, this lets your home get the electricity.

Any battery that we use to store energy falls under the category of normal batteries. Any normal battery can be classified as primary and secondary batteries based on whether they can be recharged.

Here are some significant variations between solar batteries and conventional batteries:

  • Design

Deep-cycle batteries, such as solar batteries, are those that can be repeatedly discharged and recharged without losing any capacity. Because they are not made for deep cycling, regular batteries may not last as long if they are depleted too far.

Solar batteries are able to store more energy than conventional batteries because of their increased capacity. This is crucial for solar systems because it allows for the storage and utilization of daytime energy during the night and other times when there is less sunlight.

  • Chemistry

Normal batteries can be composed of a variety of materials, including lead-acid,nickel-cadmium,and nickel-metal hydride, whereas solar batteries are often made of lithium-ion or lead-acid batteries.

  • Discharge Rate

Solar batteries are C 10 and normal batteries are C20. It is thought that the capacities of all C-rated batteries are comparable. The C10 battery will last for 10 hours, thus you shouldn’t discharge it in that time.

For industrial and solar needs, C10-rated batteries are advised because they can offer greater power in a shorter amount of time.Due to the enormous current being drawn, C20-rated batteries are typically not the best choice.

  • Cost

Clearly, solar batteries are expensive than normal batteries, but as we take it a long-term use, solar batteries are beneficial.

  • Lifespan

Prior to purchasing a battery, it is crucial to examine its lifespan. Typically, a normal battery lasts three to five years.

Moreover, solar batteries have a lifespan of 10 to 15 years. Every solar battery gradually loses storage capacity. However, not all batteries perform in the same way. Only a few solar batteries have cutting-edge designs and degrading process-slowing features.

As we understood Solar batteries are the top solution for your power backup and energy resource, next is to choose the right one that meets your power requirements. Tanway Engineerings provides various solar panels with batteries, like 6.6 kW solar system,10.6 kW solar system, 13.2 kW solar system.

A solar battery can collect solar energy during the day, and store it to utilize when you need it the best— which makes it a reliable, consistent, and sustainable energy source. 

Solar energy is cost-efficient compared to fossil fuels, however, this doesn’t mean that solar panel installation on roofs can automatically help you save cost. 

Selecting the apt solar battery system can be crucial to make sure that the solar energy system offers long-term value. Hence we need to do the research efficiently before arriving at decisions. Solar batteries can be of various types and every type has unique features. 

There are many aspects to consider and we classify them here to make it easy to acknowledge which one to look for while trying to pick the ideal solar battery for your requirements. 

Tips for choosing the best solar battery for energy storage

  1. Capacity

The capacity of a solar battery is the quantity of electric power it stores. Most solar batteries cannot operate at full capacity. For example, the standard solar battery displays 90% capacity, which means a 10 kW capacity battery uses only 9 kW as the optimum potential. The storage capacity relies on the extent of energy solar panels generate for the past 24 hours. You should find the average output, and multiply this by the number of days you wish the battery to function non-stop before it needs to charge. This means if the average daily output is 5 kW, and you wish to store energy for another 15 days, you require a 75 kWh battery. But, the solar battery storage capacity is based on the maximum daily electricity consumption for your establishment. If the solar battery capacity is not enough, then you won’t receive adequate power for the mentioned duration. 

  1. Efficiency 

This is also termed round trip efficiency, which evaluates the percentage quantity of the energy stored in the battery for your use. For example, if you look at a solar battery with 5 kWh of power charged, it provides only 4 kWh to use which makes the round trip efficiency about 80%. Additionally, for a high-performing solar panel like a 13.2 kW solar system, the solar battery bank with at least 10-20 kWh energy storage is ideal to use. 

  1. Depth of Discharge

Depth of Discharge or DoD refers to the amount of electricity you utilize from the battery. For instance, a 10.6 kw solar system battery with approximately 10 kWh capacity and 90% discharge capacity lets you utilize energy before you recharge, which keeps a part of the energy unused. Solar batteries should leave some value of energy stored inside every time, otherwise which it would minimize their lifespan significantly. So high DoD depicts a high battery capacity. 

  1. Warranty

Many solar batteries are available in the marketplace, however, every battery is not reliable and fit for your purpose. While choosing solar batteries, you need to select those with high quality and considered mid-range. They exhibit a long lifecycle, ie; cycle multiple times over the lifespan without eliminating the capacity. Check the warranty of the manufacturer and return policy to make sure they safeguard your investment if any concerns occur during installation, operation, etc. 

  1. Lifespan

The lifespan of a solar battery relies on the brand you select and the extent of capacity it can shred with time. To make sure the battery has maximum energy storage and lifespan, ask queries before you purchase. You will require to practice adequate maintenance processes if you wish to maintain the long lifespan of the battery. Protect solar batteries from excessive cold or heat and maintain them at an optimal room temperature. 

Final Thoughts

The aforementioned factors are the common tips you can consider while thinking of a battery installation for your solar panels. The right battery size depends on three specific power needs of the customer— it differs for a 10.6 kW solar system or a 13.2 kW solar system based on the power required. Installation and maintenance of solar panels need expert guidance and services from a reliable provider.

Solar Systems Explained – On Grid, Off Grid, and Hybrid Systems

Are you confused about choosing the best solar system for your property? Read on to find out!

On Grid Solar Systems

On-grid solar systems are also known as “Grid-Tie” or “Grid-Feed” systems. On Grid systems are the most common ones among the three and are the most affordable one. These systems use an inverter and do not store electricity in a battery but instead they are connected to the grid. This means that all the excess electrical power  generated by an on grid solar system, directly goes to the grid. For the energy you export you will receive credits or feed-in-tariff (FiT).

An important part of this configuration is the Meter, this electrical device keeps track of how much electricity is being produced by your solar system, and how much of it is being used by the utility grid that you’re connected to. This meter is often provided by the utility grid themselves or you could get a certified one of your own choice. In most states credits are issued only for the amount of electricity that has been exported to the grid and not for the total energy produced.

Off-Grid Solar Systems

Off-grid solar systems are also known as  “SAPS” (Stand-Alone Power Systems). An off grid system,unlike an on grid system, has a storage battery and is not connected to the electricity grid. It will continue to produce the energy you need  throughout the year and the excess energy is stored in the battery as long as the capacity of the battery installed meets your energy requirements. The off grid solar systems are comparatively more expensive than on grid systems.

Though they are more expensive, they come with the freedom of never needing to pay for your electrical usage. Why think of them as an added expense, instead those batteries are also an asset that has an intrinsic value. This configuration is best suited for households that are out of reach from a power grid but you still need electricity there. With more parts, your system gets a little more complicated and has an increased maintenance cost.

Hybrid Solar Systems

Hybrid solar systems are grid connected solar systems that have a battery storage, so a modernized version of both on and off grid solar systems. In this configuration, the solar system is connected to the local power grid via the electricity usage tracking Meter but also has a battery bank as a backup power source for the household.

During the day when you have plenty of sunlight, the panels produce electricity for the house’s needs, and the excess is stored in the battery bank. Once the batteries are fully charged the excess is exported off to the grid, thus having additional savings in the form of credits. During the night when the solar panels are not producing electricity,  your grid-connected system takes energy from the grid to power household appliances and also to recharge the battery bank in case they have depleted. Thus making this configuration the best of both worlds.
