7 Advantages of String Inverter

7 Advantages of String Inverter

These days, solar electricity generation is becoming a much more attractive option for homeowners and businesses looking to free themselves from energy bills while helping fight climate change. In the past few years, the technology available for them to do so has grown by leaps and bounds. Much of that development has focused on the most important component of such systems – the solar panels themselves. There has also, however, been plenty of advances in inverter technology, which is what makes solar power a practical option for everyday use.

Inverters, if you aren’t aware, are what convert the direct current (DC) produced by solar panels and convert it into alternating current (AC), which is the standard that almost every electrical device requires to operate. Without them, solar power would be all but useless to the average homeowner. There’s more than one type of power inverter that may be used in a solar power system, though, and today we’ll be discussing the most common one: string inverters. Without further ado, here are seven advantages of string inverters for your solar power system.

1. They’re The Most Common Option

String inverters are by far the most common type of inverter used in solar installations. They’ve been around for decades, and are what you’ll find in almost every solar system in operation today. That means they’re easy to purchase, and you won’t have any trouble researching your options while considering a purchase.

2. They’re Well-Understood Technology

Since string inverters are so common and have been around for so long, they’re based on very mature and well-understood technology. That means they have a long and proven track record, and finding someone qualified to work with them is a snap. You’ll also have a pretty good idea of how long you can expect one to last since there are already so many in operation to use as a reference.

3. You Only Need One

In a typical home solar installation, you won’t need more than one string inverter to handle the entire set of solar panels you’re installing. Since a string inverter, as its name implies, connects all available solar panels together into a single string to convert their power output to AC, you just have to add one to your system and you’re all set.

4. They’re Cost-Effective

Although a single string inverter can seem expensive, the total cost of ownership of one is nothing compared to other options, like micro inverters. With such solutions, you’ll need a single unit for each panel in your system, which means the more you scale up your installation, the more expensive it becomes. With a string inverter, you can keep adding panels to your system up to its rated capacity with much less expense.

5. They’re Easier to Maintain

With only one string inverter in use for a typical solar power system, you won’t experience high maintenance costs as you would with multiple micro inverters. In the event of an inverter problem, a repair technician won’t need to waste time tracking down where to make repairs – there’s only one place to look, and it will be in a central, easy to reach location.

6. They’re Easier to Install

When installing the components of a solar power system, it takes more time and wiring to add an individual micro inverter for every panel you’re putting in. That additional effort can translate directly into increased costs for a third-party installer or greater complexity and time investment for a DIY installation. With a string inverter, all you must do is connect each panel to the next and then to the inverter. It’s as simple as solar power gets.

7. They’re Efficient

Although you can find plenty of opinions on the subject that claim that per-panel micro inverters blow away string inverters in terms of efficiency, the claim is suspect in many cases. That’s because micro inverters are only more efficient in sub-optimal installations, where shading and other obstructions render panel output unreliable. In most situations, a string inverter will deliver the same performance in a well-designed system as comparable micro inverters, at a much lower cost-per-watt.

String it Together

As you can see, string inverters are an excellent option as a main component of a high-performance solar system. They have plenty of advantages compared to other inverter options and work well in a variety of installation conditions. Put simply, there’s a reason they’re so common and long-lived – they just work, with a minimum of expense and hassle.
