How do you get 24V from 12V solar panels?

Getting 24V from 12V solar panels is possible, but it requires some extra components and basic electronics knowledge. When combining solar panels in series, it is important to ensure that the power ratings and configurations are compatible with each other.

This means finding panels with identical voltage, current, and wattage.

To achieve 24V, two 12V solar panels can be wired in series with the positive terminal of the first panel connected to the negative terminal of the second panel. This connection between the two panels allows the output of the first panel to be transferred to the second panel, doubling the voltage of the original 12V solar panel.

In series wiring, the total wattage of the two combined panels remains the same as the two individual panels.

It is also possible to connect two 12V solar panels together in parallel, rather than in series. With parallel wiring, the total wattage of the two panels combined will be twice that of the two individual panels.

If a 12V panel produces 60 watts, two 12V panels wired in parallel will produce a total of 120 watts.

In either series or parallel wiring, special solar combiners and charge controllers may be required to safely fuse the two panels together. Along with surge protection and overvoltage protection, it may be necessary to add junction boxes, fuses, and blocking diodes to ensure voltage does not travel back in the wrong direction.

In short, creating a 24V output from two 12V solar panels is possible with basic knowledge in solar photovoltaic systems. Combining the panels in series preserves power output, while combining the panels in parallel will double the power output.

It is necessary to add components like a solar combiner, charge controller, junction boxes, fuses, and blocking diodes to ensure the safe wiring of the two panels.

How many solar panels do I need for 24V?

The number of solar panels you need to generate 24V of energy depends on several factors such as the size and wattage of the panel, the geographical location and weather, and how much power you’re aiming to generate.

Generally, a 24V solar system requires two solar panels in series, each with a minimum of 50W. To accurately determine how many solar panels you need for a 24V system, you will need to calculate the total wattage requirement for your system.

Then, divide the total wattage by the wattage rating of the solar panel to get the number of panels required. If the wattage of the panel exceeds the wattage you require, then you will have to account for the lost energy and factor that into your overall system wattage.

Additionally, all solar panel systems must include an inverter and batteries to store the energy that is produced by the solar panel, both of which must be factored into your total power requirements.

What happens if I use 24V instead of 12v?

Using 24V instead of 12V can cause a variety of problems. 24V is twice the voltage of 12V and thus will increase the power that is transferred through the circuit which can, depending on the components and equipments attached, either overload and damage components or cause them to work faster than intended leading to diminished performance in the long run, failure to comply with safety regulations and increased energy consumption.

In most cases, the components won’t be able to handle a voltage level that is twice of their designed ratings and may lead to them overheating and malfunctioning. If a certain application requires higher voltage than 12V, the components must be chosen accordingly to ensure safe operation, and this is usually done by connecting two 12V components in series to create a 24V voltage.

For example, a 24V motor or a 24V battery.

Additionally, it is important to remember that using a higher voltage than what is recommended can increase the current and other factors that can damage the electrical circuit permanently. Therefore, it is advised to thoroughly understand the components and the environment in which it is to be used in, before selecting the appropriate voltage level.
