Deciding Which of the 3 Solar Inverters Are Right for Your Home

Solar inverters are a cornerstone of any solar power system. This piece of equipment is responsible for turning the DC power your solar panels create into the AC electricity your home uses to power most equipment and your lights. But did you know that there are three different kinds of solar inverters on the market? How do you know which one is right for you? Keep reading to learn more about these different types and their pros and cons so you can make an informed decision.

String Inverters

String inverters are the most common type of inverter for residential solar power systems. As the name implies, this type of inverter requires your panels to be connected in a “string,” similar to how Christmas lights are connected in a strand together. The power from all panels is funneled through the single inverter.

As the oldest type of inverter on the market, string inverters are tried and true. They’re incredibly reliable and have been continuously improved upon over the years to keep up with the demand for more efficient solar equipment—so, in this case, being older doesn’t mean this type of inverter is outdated. However, despite constant improvements, string inverters do have one weakness in terms of efficiency; because the panels must be connected in a strand, shading on one part of the array causes a decrease in efficiency for all panels. Their central location on the side of your house makes them easy to access and repair when needed, and they’re also the most affordable type of inverter available.

Power Optimizers

On their own, power optimizers are not inverters. These are intended to work with a string inverter to help overcome the aforementioned weakness to shading. They’re mounted on the back of each solar panel and help to optimize the output of every panel on an individual level. This means that when a panel is shaded, it won’t impact the output of the rest of the array.

Obviously, this is a big benefit, but it does increase the cost of having a string inverter. Still, investing in these could pay for itself over time if you frequently deal with shading on your array.


Like power optimizers, microinverters are mounted to the back of each panel. However, they are inverters in their own right and convert DC to AC power right at the source without needing a string inverter. They’re highly efficient and minimize any impact from shading. They also make it easy to expand your system; if you want to add more panels, you just need to give each of them a microinverter instead of worrying that your string inverter is the proper size, which might mean replacing the entire inverter. However, these are the most expensive type of inverter, and their location makes them hard to maintain.

Now that you know more about the three different types of solar inverters, you should be better prepared to choose the right one for you.

New England Summers Are The BEST Summers

Why you should spend your next summer in New England.

Marconi Beach

Three years ago, I chose to attend college in Philadelphia, approximately 360 miles away from my small town in New Hampshire. I have learned many valuable lessons away from home, and have thoroughly enjoyed my time spent in Pennsylvania. One thing that my experience has taught me, however, is that it is absolutely impossible to beat a New England summer.

Fibonacci Sequence Examples: 7 Beautiful Instances In Nature

Nature is beautiful (and so is math). The last one will blow your mind.

Yes, the math major is doing a math-related post. What are the odds? I'll have to calculate it later. Many people have probably learned about the Fibonacci sequence in their high school math classes. However, I thought I would just refresh everyone's memories and show how math can be beautiful and apply to physical things everywhere around us with stunning examples.

For as long as I can remember, I have been listening to The Beatles. Every year, my mom would appropriately blast “Birthday” on anyone’s birthday. I knew all of the words to “Back In The U.S.S.R” by the time I was 5 (Even though I had no idea what or where the U.S.S.R was). I grew up with John, Paul, George, and Ringo instead Justin, JC, Joey, Chris and Lance (I had to google N*SYNC to remember their names). The highlight of my short life was Paul McCartney in concert twice. I’m not someone to “fangirl” but those days I fangirled hard. The music of The Beatles has gotten me through everything. Their songs have brought me more joy, peace, and comfort. I can listen to them in any situation and find what I need. Here are the best lyrics from The Beatles for every and any occasion.

Small towns certainly have their pros and cons. Many people who grow up in small towns find themselves counting the days until they get to escape their roots and plant new ones in bigger, "better" places. And that's fine. I'd be lying if I said I hadn't thought those same thoughts before too. We all have, but they say it's important to remember where you came from. When I think about where I come from, I can't help having an overwhelming feeling of gratitude for my roots. Being from a small town has taught me so many important lessons that I will carry with me for the rest of my life.
