How to Calculate Solar Battery Cost with Solar Battery Cost Calculator
To Calculate Solar Battery Cost, You have to add values in below Solar Battery Cost Calculator:
- Daily Power consumption of 2BHK normal house is about 10kWh and you can check your Electricity Bill as It can vary from user to user.(For 1 AC it is 2kWh) Please consider this before.
- Backup Duration meaning, For How Many Days you want to use a Battery Backup, People generally consider 1 to 3 days.
- Battery Cost per kWh may depends on Company, and Component used, So Lithium Ion and Lead Acid are two different types of Battery used. Battery price is depends on type of Battery and kWh used.
- Installation Cost is depends on Person who install this Battery.
Example of Solar Battery Cost Calculator
- Daily Power Consumption = 8 kWh.
- Backup Duration = 2 days
- Battery Cost per kWh = ₹18,000
- Installation Cost = ₹10,000
So Total Battery required : 8kWh * 2 days = 16kWh
Battery Cost = 16 * 18,000 = ₹2,88,000
Total Cost = ₹2,88,000 + ₹10,000 = ₹2,98,000
Also factor in:
- Installation cost (₹10,000 – ₹25,000)
- Inverter cost, if not included
- Maintenance, especially for lead-acid
Solar Battery Cost Calculator
Solar Battery Cost Calculator Calculate the cost of Required Battery Price according to your requirements, like battery backup of the days.
You just fill in a few simple things:
- How much electricity you use in a day
- How many days of backup you want (1 day, 2 days, etc.)
- What the battery costs per kWh (your installer will tell you this)
- Installation charges
Once you enter this info, the calculator tells you:
- How big a battery you need
- How much it will cost in total
It saves you time and helps you plan your budget better.
What is Solar Battery Cost?
Solar battery cost means how much you’ll spend to buy and set up a battery that stores the electricity made by your solar panels. It includes:
- The price of the battery itself (based on how much energy it can store)
- Installation charges
- Sometimes extra parts like inverters or cables
The more electricity you want to store, the bigger (and costlier) the battery will be.
- A small battery might cost around ₹50,000
- A bigger one for full-house backup can go above ₹2 lakh
What is the Use of a Solar Battery?
A solar battery stores the extra power your solar panels make during the day. Instead of sending it to the grid or wasting it, the battery keeps it ready for later use like at night or during a power cut.
- Keeps your lights and fans running during blackouts
- Lowers your electricity bill by using stored solar power instead of grid power
- Helps you stay powered up even if the grid goes down
- Great for villages or homes where power cuts are common
What Determines the Cost of a Solar Battery?
The price of a solar battery in India varies based on several factors:
- Capacity (in Ah or kWh): Larger batteries store more energy but come at a higher price.
- Type of Battery: Lithium-ion batteries are more efficient and have a longer lifespan compared to lead-acid batteries.
- Brand Reputation: Established brands may offer better warranties and customer support.
- Installation Costs: Professional installation ensures optimal performance and safety.
How to Estimate Your Solar Battery Requirements?
To determine the appropriate battery size for your home, consider the following:
- Daily Energy Consumption: Calculate your average daily energy usage in kilowatt-hours (kWh).
- Desired Backup Duration: Decide how many hours you want the battery to supply power during outages.
- Battery Efficiency: Factor in the efficiency of the battery, as some energy is lost during storage and retrieval.
Using these parameters, you can estimate the required battery capacity. For example, if your daily consumption is 5 kWh and you desire 4 hours of backup, a 20 kWh battery would be suitable.
Lithium-Ion vs Lead-Acid Solar Batteries: Pros, Cons & Which is Best for Indian Homes in 2025
Choosing the right solar battery type is key to maximizing ROI in India’s sunny climate. Lithium-ion batteries dominate 2025 trends due to falling prices (down 20% YoY), while lead-acid remains budget-friendly for basic setups. Here’s a comparison:
| Feature | Lithium-Ion | Lead-Acid | Best For |
|---|---|---|---|
| Upfront Cost | ₹50,000–₹1.15L (e.g., 5kWh Loom Solar) | ₹9,000–₹25,900 (e.g., 150-200Ah Luminous) | Lead-acid for budgets <₹30K; lithium for long-term savings. |
| Lifespan | 10-15 years (3,000+ cycles) | 3-5 years (500-1,000 cycles) | Lithium for high-usage homes (e.g., ACs, fridges). |
| Efficiency | 90-95% (deeper discharge: 80-100%) | 70-80% (50% max discharge) | Lithium to store more solar energy without waste. |
| Maintenance | Zero (built-in BMS prevents overcharge) | High (check water levels monthly) | Lithium for low-effort users in humid areas like Mumbai. |
| Weight & Size | Lightweight (1/3rd of lead-acid) | Heavy & bulky | Lithium for rooftop installs in apartments. |
| Cons | Higher initial cost; sensitive to extreme heat (use in shaded setups). | Shorter life increases replacement costs; environmental disposal issues. | – |
