The decision between 12-volt solar and 24-volt solar is primarily dependent on what you plan to use the voltage for. Both of these voltages can be useful, as they have their own unique features.
What are the differences and why would you want to pick one over the other? Here is a description of what both voltages are primarily used for, along with the pros and cons of each voltage:
There is a definite market for 12-volt solar power systems, especially if you like the outdoors (but still want some luxuries from home). 12-volt solar power is for making sure you are ready to go, with batteries, power banks, inverters, and charge controllers. If you are working on a boat or a van, especially if it is equipped with 12-volt outlets already, this is a great option.
The key to knowing your voltage’s maximum is knowing that you never want to have continuous currents greater than 100 amps.
Here are the pros and cons of 12-volt solar power systems:
Pros of 12-Volt Solar
There are many reasons why having a 12-volt solar power system would be beneficial, especially if you are trying to conserve energy. Here are the pros of choosing a 12-volt system:
Cons of 12-Volt Solar
While there are many advantages to using a 12-volt solar power system, especially if you are doing some off-the-grid traveling or otherwise powering appliance-type systems, there are also a few negative aspects to this system voltage. Here are the main cons to using a 12-volt solar power system:
When looking into solar, many people want a solution that works inside their home. Whether they want to run their home entirely on solar or only partially, alleviating their current power bills is usually the goal. Fortunately, with 24-volt solar power systems, this is much easier to do than when dealing with a 12-volt system.
Even though it is not the most common, installing a 24-volt solar power system does have a good amount of benefits to it. However, there are also a fair number of disadvantages to using this voltage.
Here are the pros and cons of using a 24-volt solar power system.
Pros of 24-Volt Solar
Between 12 and 24-volts, it isn’t difficult to see how having more voltage would have benefits, especially when incorporating solar into your home. So, here are the advantages that come with using a 24-volt solar system:
Cons of 24-Volt Solar
A 24-volt solar power system is useful for many things. However, it does have its drawbacks.
Here are the cons associated with a 24-volt system:
As you can see, there are multiple opportunities for using both 12-volt solar and 24-volt solar. If you are being safe about the way you are using the power, your decision is completely up to you. After all, now that you know the specifics of each voltage, you have the power to make the decision that is right for your specific needs.
