Whether you live in one of the fast-paced cities or agricultural rural communities of India, we all witness power cuts quite too often. The humongous populous cities of India on the one hand face power cuts due to their overuse of electricity, on the other hand, villages and towns face power cuts due to weather fluctuations and remoteness.
Many tier-II and tier-III cities and towns face power cuts of an hour to five on an average. Huge parts of North Indian states suffer from major power cuts while those in Uttar Pradesh, Bihar, Rajasthan, and Orissa also suffer major cuts. To beat the issue of power cuts, many of us have installed inverters at our premises, but often struggle to get adequate battery backup from purchased inverters.
To get the optimum battery backup, one should have a better understanding of batteries and the manufacturers producing batteries. The technology behind batteries has evolved many folds in the current times and manufacturers are shifting towards solar batteries from conventional batteries using electricity to recharge, to have users get the best battery life span and backup.
We have listed the types of batteries for solar panels available in the market for home and office use to make the readers choose the correct battery for their needs from the best solar battery companies in India.
Types Of Batteries Available In the Market
- Lead Acid Batteries
Lead-acid batteries are the conventional types of batteries that have an efficiency of 70 percent and usually take 16 -20 hours of recharge time to deliver 4-5 hours backup to users. Most of the manufactures offering lead-acid batteries provide warranties ranging between 3-5 years to buyers. As the technology behind traditional lead-acid batteries has become simpler and efficient over the years involving reasonably priced raw materials, the manufacturing cost has also come down and is pocket-friendly to buyers.
- Solar Batteries
Solar Batteries as the name suggests are powered by solar energy. It is a rechargeable battery that integrates a solar cell with battery power storage. It is also a tubular battery and uses captive power for its energy source. Over the last decades, the focus on solar photovoltaic systems usage to meet the growing clean power demand globally has increased manifold.
Solar batteries are based on tubular plate technology and have proved to be as stable as traditional lead-acid batteries but provide better efficiency and better life span needing less time to recharge and providing 20 percent more backup time than lead-acid batteries. Solar batteries need 8-10 hours of recharge before providing backup ranging from between 5-6 hours.
200 Ah batteries can give backup of around 4-5 hours to power 4 LED lights and 2 ceiling fans, an LED television, and to charge mobile gadgets. There are 2 types of solar batteries available in the market, Tubular batteries and flat plate batteries. To get a better understanding of batteries, Tubular batteries provide better backup, lasting longer, and offer more years of warranty than flat plate batteries.
The cost of the solar batteries available in the market depends on the battery capacity and manufacturing companies. We have tried to list the average prices range of solar batteries based on capacity:
|Battery Capacity||Average Price (Rs.)|
- Lithium-Ion Batteries
Lithium-ion batteries are considered the pioneered battery technology and have a proven track record over the years. In today’s times, lithium-ion technology has been successfully adopted as a power source for a wide range of applications. we all use mobiles and laptops that pack lithium-ion batteries inside, providing great backup time.
Despite the commercial success of lithium-ion batteries, dues its lightweight, efficiency, life span, it has not achieved large-scale production because of the elevated cost of and limited supply of lithium. Lithium-ion batteries have 99 percent efficiency, meaning providing backup of 99 percent of the battery capacity.
The batteries need 2-4 hours of charging time and give 40 percent more backup than conventional lead-acid batteries. Manufacturers give up to 15 years warranty on these kinds of batteries. The limited supply of lithium and the expensive manufacturing cost of lithium-ion batteries make it very expensive for buyers.
The available types of batteries in the market offer us the option to choose the best bang for the buck battery pack for old users and new buyers searching for the ideal battery types.
The growing interest in the demand for energy storage gives us the opportunity to know the way the energy storage systems integrate with rooftop-mounted solar panels through storage with your home or business. We also dive deep into more technical aspects of what happens inside a solar battery to store that energy absorbed via the solar panel systems.
How Do Solar Batteries Work?
Here we have listed down how solar batteries work step by step:
- Solar panels usually get mounted on the rooftop of the building premises.
- Solar panels absorb heat from the sun through photovoltaic effect, a process that generates electric current in a photovoltaic cell when it is exposed to sunlight. This effect makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy.
- The direct current (DC) so converted, flows through an inverter to generate alternating current (AC) electricity.
- The alternating current powers the home appliances.
- Surplus energy not used by appliances recharges the solar batteries.
- After the sun goes down, appliances get power from the stored energy in the batteries.
How Do Solar Batteries Work With Solar Panel Systems?
To understand how solar batteries work with solar panels, we need to quickly go through how solar panel systems function.
While installing, solar panels are installed as grid-tied, net-metered solar panel systems. Meaning when solar panels produce more electricity than required, the surplus electricity is exported back to the grid. The surplus electricity gets pulled directly from the grid when using more electricity than the solar panels are producing.
Net metering allows users to run electricity meters in reverse when extra energy is being generated onto the grid and run it forward when electricity is being pulled from the grid, with utility billing on the net for the electricity consumed.
With solar batteries installed, the surplus electricity recharges the solar battery unit instead of exporting it to the grid and after the sun goes down, the user can draw electricity from the solar battery instead of from the electric grid.
What Advantage Solar Batteries Provide To The End Users?
When the user installs a solar battery with the solar panel system, the user gets the ability to pull electricity either from the grid or the installed battery. The user has two advantages.
1. Back-Up Power From Batteries
Even though the user is always connected to the grid for running appliances at home or business, holds the option to operate all the appliances “off-grid” from the solar battery. Si in the event of a power cut due to utility shutoff or extreme weather, the user would be able to keep the essential appliances running.
To talk about the advantages of solar battery backup power, First, if the user just has a solar panel system installed without a solar battery system, the user won’t have electricity in the event of a power cut. This is because the solar panel system will shut down during power cuts so that it doesn’t send electricity back onto transmission lines while maintenance work is being carried out, which enables a safety risk.
Secondly, in case of heavy load, users get the choice of stacking additional batteries until they attain the storage capacity to run appliances in all parts of the premises. So, additional batteries make it possible to achieve whole premises backup.
2. Batteries Help Avoid High Utility Rates
Allows users to pull power from the batteries instead of from the electric grid, coupling a solar battery system with the solar panels can help avoid high utility rates. During summers, more power-consuming appliances such as air conditioners and refrigerators can be run from solar panel-generated power. And during the winter season, room heaters can act as the same medium of power generation.
What Are Solar Batteries Made of?
- Lead-acid batteries are the most common solar batteries. They have electrodes which are grids of metallic lead containing lead oxides. Lead-acid batteries are the tried and tested and are true technology of the solar battery world. Also known as deep-cycle batteries, have been used to store energy because of their reliability factor.
There are two kinds of lead-acid batteries available in the market, flooded lead-acid batteries and sealed lead-acid batteries. Lead-acid batteries are the cheapest option, making them ideal for manufacturing the most cost-effective way. They are very reliable and because the technology has been around for decades, they can be easily disposed of and recycled. The reliability is great for off-grid solar systems, or for emergency backup storage during power cuts. Having a low depth of discharge, means they have a shorter lifespan.
- In Lithium-ion batteries the electrodes are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds. This translates into a very high energy density for lithium-ion batteries, meaning they can hold more energy in a smaller space than a lead-acid battery. Besides the smaller size, the lifespan of lithium-ion batteries is at least 10 years. A longer lifespan means a higher depth of discharge, resulting in users getting to use more of the energy stored within the battery before it has to be recharged.
