Luminous solar battery

Batteries are needed to store the energy generated to be used later when required. Battery costs have fallen by 80% in the last seven years and expected to fall by another 40-50% in the next five years. But it is still considered expensive in the price-sensitive Indian market. There is a lack of large-scale demand for lithium batteries in India and hence prices have not come down as rapidly as that of solar panels. Storage seems to be the only solution for the growing transmission and distribution problems in India. Some of the popularly used solar batteries in India are Exide, Luminous, Su-Kam and Okaya. The cost of solar storage ranges between INR 6 –INR 10 per kW. In Luminous, solar batteries are designed at C10 capacity and the model starts from 20 Ah – 200 Ah, with 3 years and 5 years replacement warranty.

Frequently asked questions 

Q. How much solar plate required for battery charging

The rule is,

Recommended sales panel size = 2 * Battery Capacity (Ah)


The battery has to be charged during the day when sunlight is available, i.e from morning 9 am to evening 5 pm.

Battery charging current = Battery Ah (Capacity) / Sunlight hours

Considering, the battery Ah is 150 AH,

Battery charging current = 150 Ah / 10 H = 15 amps.

2 nos. of 150 watt Luminous PV module should be installed at the rooftop for generating 15 amps charging current. 1 no. of 150-watt solar module generates nearly 8 amps at peak. Hence, two-module of 300 watt will give 15 amps current to charge the battery.


Q. what is the backup time of battery?

Answer: The backup time of the battery is derived by Battery Capacity and Battery voltage.

So, if you buy 150 Ah (ampere-hour) battery – it is a 12 V battery,


Voltage (v) * Current (I) = Power (watts)

12 V * 150 Ah = 1800 watts, considering 20% is loss during charging and discharging

Useable power = 1800 watts – 20% loss = 1440 watt

400 watt

500 watt

150 Ah

14.4 hours 

7.2 hours 

4.8 hours 

3.6 hours 

 2.8 hours


Standard formula:

Backup time = Battery AH * 12 V * efficiency of battery / Power consumption in watts


Battery Ah = Ampere hour (capacity of the battery measured in AH)

The efficiency of battery = generally it is 80%


I have 60 Ampere hour (Ah) battery, my load is 150 watt, what will be the backup time?

Backup time: (60Ah * 12V * 0.8 efficiency) / 150 watt = 3.84 hours


Q. What to do when the battery stops giving backup?

Answer: The solar batteries are sold with a replacement warranty of 3-5 years, so if your battery stops giving backup during the warranty period, it requires replacement. Talk to battery manufacturer and request them to replace it.

The rule is, 

your battery must give less than 60 minutes of backup during the warranty period.

In case, the warranty period has expired, you can sell your old batteries to authorized re-seller or the company. The old battery could also be sold to a new luminous dealer from where you are buying new batteries.

The buyback price of old batteries depends upon recyclable lead content inside is and the weight of the old battery. It is measured in Kg after removing the electrolyte,

As on May 2017, the lead price per kg is ₹ 90

I have 100 Ampere hour (Ah) battery, how much exchange value will be given by the dealer?

Buyback price: 100Ah (battery capacity)* 27 kg (dry weight) * ₹ 90 (lead price per kg) = ₹ 2430
