What you need to know when choosing between 12V and 24V Solar Panels

It’s fantastic that you’ve chosen to go solar. Your decision will not only save you money, but it will also be beneficial for the environment. However, there are many other aspects to consider before choosing on your ultimate solar panel, and as a common man, making a decision might be challenging. It is difficult to choose from the numerous options accessible in today’s market.

You go through hundreds of brands on the market before making a final pick based on the manufacturer’s credibility, warranty, services, and other factors. Then you must decide on your panel’s ranking. Solar panels come in a variety of wattages and voltages. We also get a lot of questions from readers and potential purchasers who aren’t sure what rating their solar panel should have.

12 v solar system 

The most popular type of solar system accessible today is a 12v solar panel. It generates 12 volts, which is used to power 12 volt batteries and devices. It includes 36 solar cells that produce 0.5 volts apiece. Most 12 volt solar panels are rectangular in shape and range in size from small to large.

It is a portable stand-alone power system (SAPS) that captures solar rays and converts them to electricity using electrical converters. You’ve probably seen a ‘long’ sparkly item on rooftops. The solar panel comes next.

Where is it used? 

12v solar systems are versatile and can be used for a variety of purposes, depending on the demands of the user. Here you can compare detailed specifications. Among them are:

  • To power domestic equipment such as refrigerators.
  • To keep laptops and phones running.
  • To provide enough electricity to light the compound.
  • When caravanning, this term is used.
  • Battery power for automobiles and boats.

Pros and cons

Here are the advantages of using ag 12v solar system

  • Investing in a 12v solar panel will help you save money. The cost of purchasing a solar panel is far less than the cost of monthly electricity bills.
  • A 12v solar system is extremely efficient, and its tightly packed components help to keep heat loss to a minimum.
  • Because most products and batteries are designed for a 12v power source, factory production of 12v solar panels is high.
  • As previously said, 12 volt solar systems are the most prevalent. Inverters, fuses, batteries, and other 12v appliances are therefore widely available.
  • A 12v solar panel is small and light, making it easy to transport.
  • Solar systems that run on 12 volts require relatively little maintenance and are unlikely to break down. Repair components are easily available in the event of an emergency.

24 v system

A 24v solar system resembles a 12v system in appearance; however, to differentiate it from a 12v system, a 24v system contains twice the amount of solar cells, totaling 72 cells. It generates 24 volts, which may be utilized in either 24 or 12 volt equipment.

Where is it used? 

A 24v solar system, like a 12v solar system, can be used in a variety of locations; however, the voltage produced by a 24v solar system is substantially higher. The wattage produced is likewise impressive, ranging from 1500 to 2000 watts.

To power home appliances at home. A 24v solar system may power an entire house while using less electricity.

  • In the hospitals.
  • In banks.
  • In hotel rooms.
  • In condominiums

Pros and cons

Here are some advantages of a 24V solar system:

  • With 72 solar cells, a 24v solar panel delivers a high voltage of roughly 32-36 volts.
  • Because the current delivered is half that of the power supplied, the voltage loss is minimal.
  • Appliances of various voltages, both 12v and 24v, can be used with the 24 Volt system. A 24v solar panel, for example, may charge a 12v battery bank.
  • Because of its compatibility, heat loss is minimized.
  • A 24 volt solar system is more efficient than a 12 volt system because of its heat retention capabilities.
  • Installing on a large scale is inexpensive.

12V system vs 24V system

When determining whether to employ a 12, 24, or 48 volt system, it’s critical to evaluate your individual energy requirements. In short, if your energy needs exceed 3,000 watts, a 48 volt system is the way to go. Choose a 24 volt system if your energy needs are between 1,000 and 5,000 watts. A 12 volt system is ideal for building a smaller, DIY system for your RV, truck, or compact home. Don’t be tricked into thinking that 48 volt is the greatest option simply because it has a higher rating. You must evaluate your individual needs, existing components, and the system as a whole, much like everything else in a solar installation.
