Which Solar Panel Suits Your Needs: 12V Or 24V?

This blog is for the audience. It tries to distinguish between a 12V solar panel and a 24V solar panel. Compared to a 24V solar panel, a 12V solar panel is generally better for a small home or small business. In addition to this basic rule, different technical specifications should be considered when deciding between the two. We try to identify them from five chapters covering compatibility with:

  • Battery
  • Inverter
  • Control panel
  • Actual terms (application)
  • Material and price


The choice of solar panel level depends on the level of battery used. Generally, the 12V circuit will be connected to the 12V battery, and the 24V solar will be connected to the 24V battery. The important thing to know here is that there are no 24V batteries available in the market, but you can create one by connecting two 12V batteries in a row, as suggested by the best solar companies in Pakistan.

  • 24V panel-24V (2 * 12V battery in series)
  • 12V panel-12V battery
  • 6V battery – 2 / 6V battery


Like batteries, solar panels can also be compatible with inverter levels. For example, a 12V solar socket should be connected to a 12V inverter, and a 24V inverter and a 24V inverter should be used. The inverter has different levels, such as 12V, 24V, 48V, and more.

  • The 12V-12 V inverter-12 V battery will be connected to the solar panel
  • Battery 24V (system connection) -24V inverter-24V panel will be connected

Control panel

The cost of the inverter will fit the level of the inverter and battery. If you have a 12V battery and a 12V inverter, you will use a 12V charger control. Similarly, for 24V. One important thing to remember here is that the level of the sun should not be higher than the level of the control panel. For example, a 9-amp socket cannot be connected to a 6-amp charger controller.

The charger has different levels, from 6 amps to 53 amps. The solar panels also have different levels, e.g.

  • 10W panel-1 amp
  • 20W O-2.5 Amp
  • 180W panel-9 amps
  • 350W panel-8-9 amps


The 12V light bulbs can be used in a variety of applications, such as street lights, passenger cars, shops, small homes, home lights, phone chargers, solar packs, scientific work, solar water pumps, offices, fishing boats, etc.

24V light bulbs can be used in large buildings, hospitals, banks, offices, and electrical appliances such as offices, apartments, parking lots, parks, government offices, and solar panels. 

Limitations and pricing

The 12V solar panel available at a professional Genset supplier has 10W, 20W, 40W, 50W, 125W, 160W, and 180W, while the 24V has 330W and 350W.

The price of a 12V light bulb can be between Rs. 2,400 and Rs. 15,000. The price of a 24V solar panel can range between Rs. 11,000 rupees. 24,000.

Customers of famous water filter plant suppliers are often confused about how much solar energy can support. One key point to emphasize here is that the function of the solar panel is to charge the battery, not to activate the electrical appliance. Let us consider it in more detail.

The load capacity depends on the capacity the inverter has and the backup area depending on battery capacity. The length of the panel should be double that of the battery.

This example must be read. Small households need an average of 300 W to turn on the refrigerator, fan, and light, as well as a 1 kVa inverter that can easily support these capabilities. Let’s find out what load is used when the fire goes out. Currently, the device support time of operation depends on battery capacity. In total, a 150Ah battery supplied with 12V can store up to 1800 W of power.

A simple summary is a 150 AH * 12V = 1800 W battery

Using an acid battery with an efficiency of 70%, only a load of 1400 W should be, it can operate for 4-5 hours. Consider that a small family needs at least 300 W.

** Now, let’s calculate how long the battery should be charged and how long the solar plug should be installed, which are other questions that are often on the minds of consumers.

It depends on the amount of sunlight available. The sun’s average exposure time is ten hours. So the battery requires:

150/15 = ten hours

Assuming the battery is 150 Ah at 15 Amp, that is, if the battery receives 15 Amp, it will take ten hours to charge.

The solar panel is usually 9 amps, so 2-3 sun holes are usually required.
