What Is The Size Regulator Of A 200 Watt Solar Panel? (Details You Must Know)


After you have decided that you will use solar panels for your home, there are many more things to know. This is especially vital if you want to keep your other gadgets safe. So, you should know the various add-ons you would need when using solar panels.

You measure the size of solar panels in watts, a measurement of electrical power. The size of the solar panel system you require depends on many factors. It would also drive the sizes of the other gadgets that you connect to it.

What Is The Size Regulator Of A 200 Watt Solar Panel?

The solar regulator for a 200W solar panel must be at least 15 amps. You can derive this value from the amount of current your solar panel generates. In turn, this depends on the voltage of your panels, other than the power rating. Assuming the open voltage to be around 20 voltsOpens in a new tab., the panels would generate between 10 and 12 amperes.

What Is A Regulator For Solar Panel?

A regulatorOpens in a new tab. controls the voltage and current at which the solar panel converts sunlight into electricity. The voltage and current you need will be dependent on the system you want to powerOpens in a new tab..

Many solar panels come with a regulator. However, this is not always the case, and you may need to buy a new one. Solar panels are usually connected to a solar panel regulator, which is used to keep a constant voltage level with the help of a batteryOpens in a new tab..

You would generally charge the batteries with invertersOpens in a new tab.. A solar regulator is a device connected to solar panels. It will help regulate the electricity from the solar panels and keep it at the same volt.

Why Do You Need A Regulator For Your Solar Panel?

If you are wondering whether you need a solar regulator for your solar panels or why you need one, you can consider the following:

  1. The regulator helps keep the volts at a constant level. It does not matter what kind of weather it is outside. This will help ensure that enough power is generated to be used by the gadgets.
  1. Suppose you don’t use a solar regulator. In that case, the volts from the solar panel will change, which is not ideal for many gadgets and devices trying to use the power generated from the solar panel.
  1. There will be more consistency in power that this panel makes. It will also make it easier to integrate solar panels with your existing gadgets.
  1. And finally, it will also help prevent you from overloading your electrical system.

The bottom line is that a regulator is a vital add-on if you have your solar panel installed. It will help ensure that the power generated is correct and smooth.

What Are The Types Of Solar Panel Regulators?

Now that you have understood the importance of solar panel regulators, you might want to know the types of regulators. So, there are two main types of solar panel regulators. The first type of regulator is the pulse width Modulation. PWM stands for Pulse Width Modulation

It acts as a mediator that directly connects the batteries and your solar panels. These regulators need a transistor to open the array instead of a relay. Also, you need to match the solar panel’s voltage to the battery bank to avoid power charging loss.

Therefore, high power loss occurs if any mismatch happens between them. Also, these regulators are not costly and are used widely for home and industry purposes. Also, it is not very flexible, which you can consider a drawback.

And the second type of regulator is Maximum Power Point Tracking. It is more developed than PMW regulators. These devices allow the solar panel to work at its max level or, to be more precise, the right voltage for power output. 

Also, the MPPT regulators can be more efficient depending on the solar panel’s battery voltage and operating voltage(Vmp). MPPT controllers not only prevent the solar power system from power loss but also get excess power from the solar array.

Even though it is more expensive, it has high charging efficiency. It is very flexible. This is important for firms. Also, it has a higher warranty period than the PWM regulator.

What Is The Size Regulator For The Solar Panel?

The size of the solar panel regulator will depend on the size of the solar array in use. A solar regulator will have a voltsOpens in a new tab. rating on it, and this is because solar panels have a volt output. The voltage output is what must be regulated by the solar regulator.

The solar regulator will have a max and min volt rating. Your regulator will have the capacity to maintain these volts. The value of the voltage rating would lie anywhere between 6 and 60 volts.

In addition to this, you may also observe that regulators have a rating based on their amps. This value falls between 1 and 60 amperes. You also have to consider a safety factor of 0.25 when sizing your solar regulator.

How Heavy Duty Is The Solar Panel Regulator?

A solar regulator is a durable material that will withstand outdoor weather conditions. The outer shell of the regulator should be made out of thick plastic or metal that is resistant to heat and moisture.

It may also be helpful to buy a regulator that can stand a certain weight as it will be needed to hold the solar panel in place.

How Does A Solar Panel Regulator Work?

A solar regulator is a device that monitors the output of a solar panel. Then it takes this feedback and regulates it. As the solar panel is exposed to various levels of sunlight, the output changes a lot.

If a solar panel is left unregulated, it will damage the devices connected to it. If the voltage level of the solar panel is too high, it will overcharge the batteries; also, if it is too low, it will not charge the batteries.

How To Choose The Best Solar Panel Regulator For Our Solar Panel?

It would be best to consider some things when picking a solar panel regulator:

  1. First of all, think about how the electricity distributes itself when using the regulator.
  2. Then, think about how you would make the connections. Do you want to have it connected directly to the solar panel?
  3. Think about the power you are likely to use when picking the solar panel device.

How Long Will a Solar Regulator Last?

A solar regulator is vital for a solar panel charger to prevent damage to the solar panel. And also to keep the output at a safe rate. A solar regulator should be able to last for years, even with regular use.

However, it is vital to keep in mind that various types exist. And many brands of solar devices may have varying durability. A suitable solar panel device can make your solar panel more efficient and raise the lifespan of your panel.

Conclusion

Solar panel regulators can be vital for your solar panel and diminish the loss of electricity when it travels through wires and other devices. Picking the right one can make all the difference. Remember to select a solar panel regulator with the correct volts, current, and needed power.
