A 150Ah solar battery is a deep-cycle energy storage device that can store the DC electricity generated by solar panels in battery-connected solar systems. The term 150Ah means the battery can deliver 150 amperes of current over 1 hour or 15 amperes of current over 10 hours in theory. In real life, the backup you get changes with the load and battery condition. 

The 150Ah solar battery price in India in 2025 ranges between ~Rs 9,000* to ~Rs. 54,000*.   

*Please note: The above-mentioned cost range is based on standard market research. The actual 150Ah solar inverter battery price can significantly vary from this given range. The final cost in India depends on factors such as the type of battery (lead-acid or lithium batteries), brand, warranty, taxes, and the manufacturer’s discount. SolarSquare does not manufacture, install, sell, or endorse any solar battery brand. We install on-grid rooftop solar panel systems for homes, housing societies, and commercial buildings. 

A 150Ah solar battery can power basic home appliances, such as LED lights and fans, and also charge laptops and mobile phones. However, it can’t power heavier loads like ACs or geysers. 

These batteries are mandatory additions to hybrid and off-grid solar systems in remote and rural areas with no grid supply. However, installing on-grid solar systems is a much better and economical deal in areas with a reliable grid connection. That’s because batteries increase the installation and maintenance cost of solar energy systems. 

In this blog, we’ll break down the estimated 150Ah solar battery price in India in 2025, explain the factors that result in price variation, and chalk down the types, pros, and cons of a 150Ah solar battery. We will also explain what 150Ah solar battery backup time is, how to calculate it, and why you should choose on-grid rooftop solar for housing societies and homes in urban areas instead of going off-grid.

TL;DR Summary Box: How Much Ah Battery is Required for a Home?

For Indian households in remote and rural areas where grid electricity is either very unreliable or not available, a 150Ah solar battery is a good starting size. It gives a sensible balance of cost and backup for essentials like lights, 1-2 fans, and phone/laptop charging. 

  • If you go any lower in capacity? The backup hours will drop quickly. 
  • If you go any higher (say 200Ah or two 150Ah batteries)? The cost will rise sharply. 

Simply put, if your plan is, say, 4 LED lights + 2 fans + a TV for about 3-5 hours, a single 150Ah battery is usually fine. For longer hours or extra appliances, you’ll have to size up.

Factors Affecting the 150Ah Solar Inverter Battery Price

The actual 150Ah battery price can significantly vary based on factors including, but not limited to, the brand, battery chemistry (is it a tall tubular battery or a lithium battery?), the quality of raw materials used, and even the manufacturing scale. 

Let’s understand all the major factors that influence the final 150Ah solar inverter battery price in India in 2025:

  • Battery chemistry: A lithium battery can be 3-4 times more expensive than a lead-acid tall-tubular battery of the same chemistry. In fact, the cost variations between different types of lithium batteries are also huge. Hence, the final 150Ah solar battery price depends on the exact battery you’ve purchased. 
  • Raw materials used: The final 150Ah solar battery price depends on the cost of raw materials at the time the battery was manufactured. If the raw materials were expensive, so would the end battery be.
  • Extended warranties and after-sales services: The final price is significantly impacted by the warranty and after-sales services offered by the manufacturer. Longer or replacement-type warranties and a strong service network raise the price.
  • The manufacturing scale: If the batteries are produced in bulk, they will tend to cost less.
  • The brand reputation: Better-known brands often use higher-quality parts, offer longer warranties, and follow safety standards. This usually means better reliability and higher prices than cheaper alternatives that wouldn’t last even half the life of high-quality batteries. 
  • Import taxes: Whether or not the product or raw materials are imported influences the final 150Ah solar battery price. Import duties, GST, and shipping add to the final price. Packs or cells brought in from abroad usually cost more.
  • Dealer/seasonal offers: Dealer margins, festive offers, and location-based logistics can drive the prices up or down.

Why Does the 150Ah Battery Price Vary For Branded and Unbranded Products?

Premium brands invest heavily in advanced testing to determine the cycle-life and operating temperature range of their batteries. This minimizes the risk that any defective battery will hit the consumer market for sale. That’s one of the major reasons why branded 150Ah solar batteries cost more than unbranded batteries that follow no safety guidelines or advanced testing protocols. 

Let’s check out all the reasons why branded products from premium lithium battery manufacturers are generally more expensive: 

  • They use high-quality raw material: Reputed manufacturers never compromise with product quality. They ensure they use original and high-quality raw materials so the resulting batteries work longer and perform better.
  • They provide extended warranties: This reduces the risk to the consumer and places the battery failure risk on the manufacturer, as extended warranties usually offer free replacements if the battery malfunctions. Hence, the cost tends to be higher. 
  • They use advanced manufacturing techniques: Premium makers also invest in R&D and automate production to reduce human error. This affects the final 150Ah solar battery price.   
  • Their products meet safety compliance: Brands ensure their products are safe for use, and they obtain certifications like IEC and BIS to prove it. 

What is a 150Ah Solar Battery?

A 150Ah solar battery is a deep-cycle battery that’s rated to theoretically deliver 150 amperes of current for one hour, or proportionally less current for longer periods. Deep-cycle means these batteries are specifically designed to be deeply discharged and then frequently recharged without the battery getting damaged.  

While Ah does represent the actual electrical charge a battery can hold, which in this case is 150 ampere-hour, in the real world, it changes with the load and battery condition. For instance, lighter loads drain the battery more slowly than heavier loads like ACs and geysers. 

The usual voltage of a 150Ah battery is 12 volts. However, depending on the system, the batteries can be combined to produce a higher voltage. For example, two 12V batteries in series give 24V, and four in series give 48V.

Here are the main features of a 150Ah solar battery:

  • Nominal voltage: 12V. However, you can connect in series to make 24V (2 batteries) or 48V (4 batteries).
  • Discharge rate: C10 or C20 rating (10-hour or 20-hour discharge).
  • Cycle life: 500-1,000 cycles for lead-acid batteries and 2,000-5,000 for lithium batteries.

C-10 vs C-20 Battery Rating: Which is Widely Used, and Why?

The C-rating in a solar battery is a simple way to understand how battery capacity is measured and tested. The C stands for Capacity. The number after C indicates how many hours the battery is discharged to measure its full capacity. This rating is so important as it directly affects how much power you can actually get from your 150Ah solar battery in real-world use.

  • A C-10 rated 150Ah battery: C-10 here means the battery can theoretically deliver its full 150Ah capacity when discharged over exactly 10 hours. In practical terms, this means the battery provides 15 amperes of current (150Ah ÷ 10 hours = 15A) continuously for 10 hours before being completely discharged. 
  • A C-20 rated 150Ah battery: C-20 means the battery here can theoretically deliver its full 150Ah capacity when discharged very slowly over 20 hours. 

C-10 batteries are preferred for 150Ah solar battery applications because home inverters typically operate at higher discharge rates. When you run normal household loads like 2-3 fans (4-5A each), LED lights (1-2A total), and a TV (8-10A), your total current draw can easily exceed 15-20A during peak usage. A C-10 battery is designed and tested to handle these realistic load conditions better.

Here’s a head-on comparison between C-10 and C-20 ratings for a clearer understanding: 

Rating TypeDischarge TimeCurrent Drawn
C-1010 hours15 ampere
C-2020 hours7.5 ampere

What Are the Types of 150Ah Solar Batteries?

The two main battery configurations are lead-acid tall tubular and lithium batteries. Lithium iron phosphate batteries are more commonly used in solar energy systems than any other form of battery because they last longer and require less maintenance. 

  • Tall-tubular batteries: A tall-tubular battery is a type of lead-acid battery where the positive plates are made in a tube-like shape instead of flat plates. They need regular maintenance every 2-3 months. 
  • Lithium iron phosphate batteries: A Lithium Iron Phosphate battery uses lithium compounds instead of lead and acid. These batteries have a built-in Battery Management System (BMS) that constantly monitors and protects the battery from overcharging, deep discharge, and overheating. Unlike lead-acid batteries, LiFePO4 batteries are completely sealed and never need water or any maintenance.

Here’s a tabulated snapshot of how the two types of 150Ah batteries differ:

*Please note: The above-mentioned cost range is based on standard market research. The actual 150Ah solar battery price can significantly vary from this given range. The final cost in India depends on factors such as the type of battery (lead-acid or lithium batteries), brand, warranty, taxes, and the manufacturer’s discount. SolarSquare does not manufacture, install, sell, or endorse any solar battery brand. We install on-grid solar systems for homes, housing societies, and commercial buildings. 

Which Battery is Best, 150Ah or 200Ah?

Choosing between 150Ah and 200Ah solar batteries depends on your backup power requirements, budget constraints, and available installation space. The decision involves balancing initial investment, backup duration requirements, and system complexity.

Here’s a head-on comparison between 150Ah and 200Ah lithium batteries so you can choose the one that’s more suitable for your needs:

What is the 150Ah Solar Battery Backup Time?

150Ah solar battery backup time is the total number of hours your 150Ah solar battery can continuously power the connected appliances before the battery is completely discharged and needs recharging. 

For example, if your battery provides 8 hours of backup time, it means you can run your lights, fans, and TV for 8 continuous hours during a power outage before the battery runs out of stored energy.

It can be calculated using a simple formula:

Backup Time = (Battery Capacity × Battery Voltage × Efficiency) ÷ Connected Load

*Please note: The actual backup time will vary from what the formula might provide, as it depends on several real-world factors, including battery age, type of load, ambient temperature, and inverter efficiency.

Here’s a simple demonstrative table that uses the formula above to calculate the 150Ah solar battery backup time for different loads:

Load descriptionPowerCalculationBackup time*
4 LED bulbs + 1 fan100 watt(150×12×0.95)÷10017.1 hours
TV + STB + 2 fans200 watt(150×12×0.95)÷2008.55 hours
Mixed home load300 watt(150×12×0.95)÷3005.7 hours

*Please note: The actual backup time will vary from what the formula might provide, as it depends on several real-world factors, including battery age, type of load, ambient temperature, and inverter efficiency. Real-world performance is typically 10-20% lower than calculated values. Also, the efficiency considered for lithium batteries in the table above is 95%.

How Many Solar Panels Can Charge a 150Ah Battery?

The actual number of solar panels needed to charge a 150Ah solar battery depends on several real-world factors: 

  • Daily sunlight hours
  • Weather conditions throughout the year
  • The angle and direction your panels face
  • Any shadows from trees or buildings
  • The quality of your solar panels
  • How much do you discharge your battery each day

These factors can significantly affect how much power your panels actually generate compared to their rated capacity.

Here’s a simple formula that can provide the estimated number of panels:

Solar Panel Wattage Required = (Battery Ah × Battery Voltage × 1.3) ÷ Peak Sun Hours

Important Disclaimer: This formula gives you a basic estimate, but real-world results can vary significantly. The calculation assumes perfect conditions and doesn’t account for factors like cloudy days that reduce panel output, dust or dirt on panels that blocks sunlight, panel efficiency dropping in very hot weather, energy losses in wiring and charge controllers, seasonal changes in sun angle, and the fact that you might not get perfect peak sun hours every day. 

Suppose the peak sunshine hours your area gets are 5 hours. Based on that, here’s the ideal wattage needed to charge a 150Ah, 12V battery:

150 Ah x 12V x 1.3  ÷ 5 Hours = 468 watts*

If you’re using a 250-watt solar panel, it will require ~2 solar panels to charge a 150Ah solar battery.

*Disclaimer: This calculation assumes deep daily use and a fixed allowance for losses. It does not account for factors such as shade, dust, heat, seasonal changes, panel angle, or limits set by your battery’s BMS and solar panel charge controller. Real-world charging can be much slower. 

Is a 150Ah Solar Battery Sufficient For a Home?

If the home in question belongs to a small family that needs to power normal appliances like a few fans, lights, and maybe a small LED TV for 4-6 hours, then a 150Ah solar battery will be sufficient. 

However, understanding which appliances can operate on a 150Ah battery can help you plan your backup power usage effectively.

  • Bulbs
  • Fans
  • Small TV
  • Set-top-box
  • Mobile charger
  • LED tubelights

A 150Ah solar battery is not ideal to power heavier appliances like ACs, washing machines, geysers, microwaves, and refrigerators. 

On-Grid vs Off-Grid Solar Systems, Which is Better For Homes?

Installing on-grid solar systems offers a much better ROI than off-grid solar systems because on-grid solar is cheaper, as it does not require batteries. In fact, the government offers homeowners and housing societies a subsidy under the PM Surya Ghar Muft Bijli Yojana for installing on-grid rooftop solar systems. This financial assistance is not provided if you install off-grid systems. 

Installing off-grid solar systems makes sense only if you live in remote and rural areas where there’s no power grid or the grid supply is very unreliable. However, if you live in urban areas with a reliable power grid, you won’t require a battery; hence, on-grid solar will be better. 

On-Grid Solar System Installation Cost vs Solar Savings in 25 Years

On-grid solar systems, when sized appropriately, can reduce electricity bills by 90% or more. This, and the fact that electricity becomes expensive by 3-6% annually in India, on-grid solar will end up saving tens of lakhs of rupees for you in 25 years of its life.

Here’s a head-on comparison between the estimated on-grid solar system installation cost in Nagpur vs the savings this system will offer in 25 years of its life:

Solar System Size Solar Panel Price in Nagpur With Subsidy (Starting Price – Indicative for Base Variant)* Solar Savings in Nagpur in 25 Years*
2 kWp ~ Rs. 1.15 lakh~ Rs. 11.05 lakh
3 kWp~ Rs. 1.32 lakh~ Rs. 16.58 lakh
4 kWp~ Rs. 1.77 lakh~ Rs. 22.11 lakh
5 kWp~ Rs. 2.27 lakh~ Rs. 34.43 lakh
10 kWp~ Rs. 5.02 lakh~ Rs. 68.86 lakh

*Please note: The above-mentioned solar plate price is indicative as of 21st August 2025 for the SolarSquare Blue 6ft variant. The final cost of installing an on-grid rooftop solar panel system at home depends on your DISCOM charges, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Prices are subject to change. Additionally, while calculating savings, we have considered the annual tariff escalation at 3% and the annual degradation at 1%. The actual final savings from solar panel installation depend on the types of solar panels you’ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt/dust, and how well you maintain your panels after installation.
