It is superior that you’ve got determined to go photo voltaic. Your determination won’t solely lead to financial savings for you however can also be a superb choice for the atmosphere. But there are numerous completely different parameters to display earlier than deciding upon your closing photo voltaic panel and being a standard man, it turns into troublesome to determine. It turns into troublesome to decide on between the tons of decisions obtainable available in the market at the moment.
You first display via a whole lot of manufacturers obtainable available in the market after which come to a closing determination, primarily based on the producer’s credibility, guarantee, companies, and so on. Then that you must determine the ranking of your panel. A solar panel is accessible in a variety of wattages and volts. We additionally obtain many queries from our readers and potential consumers who’re confused in regards to the ranking of the photo voltaic panel they want to purchase.
This weblog is for these viewers. It tries to differentiate between a 12V photo voltaic panel and a 24V photo voltaic panel. A 12V photo voltaic panel is usually appropriate for small residences or initiatives of smaller dimension in distinction to a 24V photo voltaic panel. Other than this fundamental thumb rule, there are completely different technicalities to contemplate when deciding between the 2. We have tried to distinguish between them foundation 5 factors:
- Compatibility with Battery
- Compatibility with Inverter
- Compatibility with Charge Controller
- Real Use Case (Applications)
- Range & Pricing
1. Compatibility with Battery
The alternative of the ranking of a photo voltaic panel will depend on the rating of the battery used. Generally, a 12V photo voltaic panel needs to be paired with a 12V battery and a 24V photo voltaic panel needs to be used with a 24V Battery. An necessary level to be famous right here is {that a} 24V ranking battery is just not obtainable available in the market, however you’ll be able to create one by becoming a member of two 12V batteries in a collection connection.
- 24V panel – 24V (2* 12V batteries in collection connection)
- 12V panel – 12V battery
- 6V Panel – 2/6V battery
2. Compatibility with Inverter
Like the battery, photo voltaic panel must also be appropriate with the rating of the inverter. For instance, a 12V photo voltaic panel needs to be paired with a 12V inverter and a 24V photo voltaic panel needs to be used with a 24V inverter. Inverters can be found in numerous scores like 12V, 24V, 48V, and so on.
- 12V battery – 12 V inverter – 12 V photo voltaic panel might be linked
- 24V battery (linked in collection) – 24V inverter – 24V photo voltaic panel might be linked
3. Compatibility with Charge Controller
The rating of a charge controller ought to match with the scores of the inverter and the battery. If a 12V battery and a 12V inverter is there, a 12V Charge controller needs to be used. Similarly, for 24V. One necessary factor to bear in mind right here is that the photo voltaic panel’s ranking shouldn’t be greater than that of the cost controllers. For occasion, a 9 Ampere photo voltaic panel can’t be paired with a 6 Ampere cost controller.
A Charge controller is accessible in a variety of scores from 6 Ampere to 53 Ampere. Solar panels are additionally obtainable in numerous scores e.g.
- 10W Panel – 1 Amp
- 20W Panel – 2.5 Amp
- 180W Panel – 9 Amp
- 350W Panel – 8-9 Amp
4. Application
A 12V photo voltaic panel can be utilized for various functions like avenue lights, vacationer van, outlets, small properties, dwelling lighting, cell charging, photo voltaic bag, science challenge, photo voltaic water pump, workplace, fishing boats, and so on.
A 24V photo voltaic panel can be utilized in huge properties, hospitals, banks, places of work, on grid functions like factories, residences, parking, parks, authorities constructing, photo voltaic parks, and so on. To see our case studies.
5. Range & Pricing
12V photo voltaic panel is accessible in 10W, 20W, 40W, 50W, 125W, 160W and 180W, whereas 24V is accessible in 330W and 350W.
Price of a 12V photo voltaic panel can differ in between Rs. 2,400 and Rs. 15,000. Price of a 24V photo voltaic panel can differ in between Rs. 11,000 and Rs. 24,000.
Solar Panel Buying Guide
Customers are sometimes confused as to how a lot load might be supported by photo voltaic panels. One necessary level to focus on right here is that the perform of a photo voltaic panel is to cost the battery and to not make home equipment work. Let’s discuss extra about this intimately.
Home load will depend on inverter load capability and again up energy and time will depend on the battery’s vary. A panel’s vary needs to be double that of the battery.
Must learn this instance, a small dwelling wants a minimal of 300 W to run a fridge, fan, and light-weight which might be simply supported by a 1 kVa inverter. Let’s calculate and see what’s the load of the home in use in case of a Power failure. Now, the time for which home equipment will work on again up will depend on the battery’s capability. Typically a 150Ah battery with 12V ranking can retailer upto 1800 W of energy.
Simple Calculation is 150 AH battery * 12V = 1800 W
Taking a lead acid battery with 70% effectivity solely 1400 W load needs to be obtainable and can work for 4-5 hours. Considering a small dwelling wants a minimal of 300 W.
Thumb Rule:
**Now let’s calculate in how a lot time will a battery be charged and what number of photo voltaic panels are required to be put in, that are different widespread questions within the minds of the consumers.
This will depend on the daylight’s availability. On a median, daylight is there for 10 hours. So a battery will take:
150/15 = 10 hrs
Assuming 150 Ah battery and 15 Amp of energy, i.e. if the battery receives 15 Amp it is going to take 10 hours to cost.
A Solar panel is usually 9 Amp, so sometimes 2-3 photo voltaic panels might be required.

Summary
This weblog is devoted for readers to determine as to what number of photo voltaic panels they need to purchase to help the conventional functioning of their home, in case of an influence minimize, what voltage of photo voltaic panel – 12V or 24V is appropriate for you, and for what number of hours my fan and lights will work on photo voltaic in case of a load shedding. Loads of this relies upon the scores of the battery, inverter and cost controller. We hope we had been in a position that will help you to some extent. You can preserve writing to us for extra such queries in remark part.
