What is a solar optimizer?

How does it work?

Do you need a solar optimizer when you set up your solar power system?

A solar optimizer is a type of conversion equipment used to improve the amount of solar energy a solar panel or solar system can absorb.

Although optimizers work in different ways depending on the situation, most of them improve the precision of the panel’s input as well as its performance output. These are DC to DC converters.

If you have a solar panel system setup, you don’t have to have a solar optimizer. However, this item can make a big difference in the way your solar energy works, so it can be a useful addition.

Many people who use solar optimizers do so because their solar panels cannot get enough direct sunlight. When you have your panels set up in a place with too much shade, an optimizer can improve their efficiency.

In this article, you’ll find two different solar optimizers to choose from. Take a look at our detailed reviews and check out the differences between the two. From there, you should have no trouble picking your favorite and installing it for a more powerful solar energy experience.

Read on to learn more about finding the right solar optimizer.

Option #1

SolarEdge 320W MC4 Type Input DC Optimizer

SolarEdge 320W MC4 Type Input DC Optimizer- P320

The SolarEdge 320W MC4 Type Input DC Optimizer works best on solar panel setups designed for high-power outputs. It’s designed for use on 60-cell systems and provides an MPPT range from 8 to 48 VDC. This optimizer includes an MC4-type hookup and is easy enough for many customers to install on their own without the need to contact a professional.


  • This optimizer makes it easy to monitor the outputs of your solar panel system.
  • The optimizer improves problems related to manufacturing in some instances.
  • This choice also improves efficiency when solar panels are installed in poor locations, such as in too much shade or an incorrect orientation on the roof.

What We Liked

  • This optimizer installs very easily with just a single bolt. We feel that quick and easy installation makes the optimizer a much more beneficial addition to solar panel setups for both homes and commercial properties, since it cuts down on the need to pay a professional to handle installation.

What Could Be Improved

  • This option only works for certain hookups and connections, and it’s not a universal design. If customers don’t have the right type of solar panel setup, they cannot use this device. For this reason, we feel it should come with other options included so it could be used by more customers.


  • This optimizer is a durable, long-lasting piece of equipment that works well as soon as it’s installed and hooked up.
  • This offer does what it’s intended to do without much trouble and works for years as part of a solar panel system setup.
  • This choice comes with everything needed to install it right out of the box.


  • This optimizer may arrive missing some parts or not functioning out of the box, but the company will send a replacement if this occurs.
  • This option may not be heavy-duty enough for all setups.
  • In some rare instances, this offer may not provide enough extra energy for solar panel systems.

Option #2

Goal Zero Yeti Lithium MPPT Solar Charging Optimization Module

Goal Zero Yeti Lithium MPPT Solar Charging Optimization Module

The Goal Zero Yeti Lithium MPPT Solar Charging Optimization Module features an MPPT-style solar optimizing setup designed for use specifically with Goal Zero Yeti Lithium solar panel systems. This offer works with the Goal Zero Yeti 1000 and 1400 Lithium systems and comes standard with the Goal Zero Yeti Lithium 3000 system out of the box as well.


  • This choice features an 8mm charging port that allows 15-22V of power.
  • Each port processes up to 150W of solar energy.
  • This option also allows wall charging and provides up to 360W of power through the included wall charging port set.

What We Liked

  • This offer works very well for days with poor sunlight or locations with too much shade. Customers see a lot of improvement on their solar panel systems on these days, and most customers feel this choice is well worth it because of its increased efficiency in poor weather conditions.

What Could Be Improved

  • We feel the biggest improvement for this option would be to include it with all of the Goal Zero Yeti Lithium models instead of just one of them. Since it’s designed only to work with this type of solar panel system setup, then it should come standard with these choices it works with. As it is now, it is an additional cost for customers.


  • This choice installs quickly and easily for efficient use in no time right out of the box.
  • Customers report plenty of assistance from customer service when needed with this offer.
  • This option works well for improving solar wattage even in situations where the solar panels don’t receive much light.


  • This optimizer may break down or become damaged fairly quickly after installation, even when installed and used as according to the directions.
  • This offer may arrive missing some parts or screws required for installation.
  • Many customers report this choice running loud and causing too much noise for use anywhere near campsites.


Did you find the best solar optimizer for your needs? These choices can help you improve your solar energy and make the most out of any solar panel setup, no matter what the conditions of your yard or climate might be. However, it’s important to make sure you pick the one that works bets for you so you can give it the best possible chance of working well.

How can you tell which of these two is better for you? Here are a few tips to keep in mind:

  • Some solar optimizers are designed for use only with a specific type of solar panel setup. Pay close attention to make sure the one you’re considering works with the setup you have in place for best results.
  • Some solar optimizers create more outputs or require more inputs than others. You will need to have some understanding of the energy levels involved in your solar optimizer as well as your solar panels before you choose one of the two products listed above.
  • It’s important to choose a solar optimizer you feel like you can safely and easily install. If you don’t, then be sure you have the funds to hire a professional to install it for you.
  • If you have a large solar panel setup, you’ll need to buy multiple optimizers. Keep in mind the price as well as how easily the optimizers work in conjunction with each other to choose the right one.
  • Finally, pick a solar panel optimizer that will hold up well in your climate. Some may feature more cold weather functionality than others, and it’s always important to pick solar equipment designed to work where you live.

When you pick the right solar optimizer, you’ll be well on your way to a better solar panel experience in no time. Choose one of the two we have listed above and enjoy the improved solar energy results!
