12V Vs 24V Solar Panel: Which To Choose?

12V Vs 24V Solar Panel: Which To Choose? It is wonderful that you have chosen to go solar. Your decision will not just save you money, but it will also benefit the environment. However, there are several factors to consider before selecting your final solar panel and becoming a regular person, it becomes difficult to make a decision. It becomes tough to choose between the numerous alternatives available on the market today.

You start by skimming hundreds of brands available in the market and ending up making a selection based on the manufacturer’s reputation, guarantee, and other factors. Then you must select a rating for your panel. A solar panel may have any wattage or voltage level. We also get numerous inquiries from our readers and potential buyers who are unsure about the rating of the solar panel they desire to purchase.

What Is The Solar Panel?

12v vs 24v solar panel

Solar panels, often known as photovoltaics, are large rectangular, shiny objects that turn sunlight into electricity and are typically placed on roofs. For smaller residences and constructions, 12V solar panels are preferable; however, 24V panels are better for bigger installations. 

Solar panels are becoming increasingly popular among individuals who want to decrease their carbon footprint by switching from traditional energy production. Others get them for economic reasons, while others acquire them in order to preserve the planet and money in their wallets. The amount of electricity you require will determine whether a 12V or 24V solar panel is suitable for you. A plethora of solar panels may be confusing and elicit uncertainty, but it is essential to figure out which one best suits your requirements before making any purchases.

Difference Between 12v And 24v Solar Systems

The most important aspect to consider before investing in solar panels is their size. The majority of 12-volt systems are suited for small uses such as boats, automobiles, and RVs. A 12v system can certainly be used to light the porch and lawn chairs at a family home. However, if you want to power a house and increase its size, a 24-volt solar panel may be helpful. The initial cost of a 24v system would be significant, but the ROI would also be excellent.

Over the years, the sun, a natural source of light, has arguably been one of the best alternatives to fossil fuels. Solar panels have grown in popularity among many individuals for a variety of reasons, including their environmental friendliness. Solar energy generated through solar systems is pollution-free, so there are no harmful carbon emissions released as a result.

What Is The 12V Solar System?

The most popular form of the solar system today is the 12v solar panel. It generates 12v, which is used for devices, and power batteries which are also 12v. It has about 35 solar cells, each of which produces 0.5 v. The majority of today’s 12v solar panels are mostly rectangular in shape, ranging from tiny to huge sizes.

It is a self-powered stand-alone power system (SAPS) that absorbs solar radiation and converts it to electricity using electrical converters. I am guessing you have noticed something shiny on the roof of your house. That must be the solar panel, is not it?

Best Uses Of The 12V Solar

Depending on the user’s demands, they may be utilized in a variety of settings. These are some examples:

  • In households, it is used to power everything from refrigerators to appliances.
  • To run the computers and phones.
  • To light the compound, we will need electricity.
  • Used when traveling in the caravans.
  • Provide electricity for automobile and boat batteries.

Advantages Of The 12V Solar

Solar panels have a variety of advantages over other energy sources. It is virtually difficult to revert back to another type of energy.

  • Buying a 12v solar panel may save you money. The expense of buying a solar panel is many times lower than that of paying for monthly power bills.
  • A 12v solar system is highly efficient, and the aid of the closely packed component in the reduction of heat loss.
  • Many devices and batteries are designed to work with a 12v power supply, so there is a lot of interest in producing solar panels for them.
  • As previously said, the most frequent type of solar system is a 12v solar system. As a consequence, its inverters, fuses, batteries, and other 12v devices are readily accessible.
  • The 12v solar system is easier to maintain than a traditional 15-20amp battery bank. Their failure rate is slim. Repair parts are readily available in the event of a malfunction.
  • You may readily add additional solar panels as long as there is enough space to support them all.
  • A 12v solar panel is lightweight and portable.

Disadvantages Of The 12V Solar

  • A 12v solar panel heat loss is higher over time due to its low voltage.
  • Only other 12v devices can be connected to a 24-volt solar system.

What Is The 24V Solar System?

A 24-volt solar system may be mistaken for a 12-volt system because it has the same number of solar cells, however, a 24v system contains twice as many solar cells total, totaling 72. It generates electricity used in either 24 or 12v electrical appliances and is rated at 24 volts. 

Best Uses Of The 24V Solar

A 24v solar system, like a 12v solar system, maybe utilized in many areas; however, the voltage produced by a 24v is significantly higher. The watts generated are also substantial, ranging from 1500 Watts to 2000 Watts. To power home appliances at home. A 24v solar system is sufficient to power a whole house on minimal electrical demands.

  • Hospitals
  • Banks
  • Hotels
  • Apartments

Advantages Of The 24V Solar

  • A 24-volt solar panel generates a high voltage of 32-36 volts utilizing 72 solar cells.
  • Since the supplied current is half of the power supply voltage, the drop in voltage is quite small.
  • The 24-volt system can charge appliances with different voltages, both 24v and 12v. A solar panel, for example, maybe charged by a 12v battery bank.
  • Because of its adaptability, minimal heat loss is experienced.
  • A 24-v battery system is more efficient than a 12v solar panel because of its heat retention qualities.
  • It is inexpensive to set up on a large scale.

Disadvantages Of The 24V Solar

  • A 24v solar system will cost more than a 12v system, but it is still a bargain.


I hope I was able to provide you with some insights and answers to most, if not all, of your queries regarding the distinction between 12v and 24v solar systems. Choose the right solar system for you. If you want mobility or a cheaper option, go for a 12-volt system. A 24-volt system will provide a superior return on investment at home or other businesses. You may also charge your battery bank and use it for convenience.
