When investing in a solar system for your home or business, choosing the right type of inverter is one of the most important decisions you’ll make.

There are two main types of inverters used in residential solar PV systems:
Microinverters
String Inverters

Let’s explore the differences, pros and cons of each, and how to decide which one fits your needs best.

What Is a String Inverter?

A string inverter is the most common type of inverter. It connects a “string” of solar panels to one central inverter, which is usually installed near your main switchboard.

Pros:

• Cost-effective
• Easy to install and maintain
• Suitable for homes with simple roof layouts and no shading

 Cons:

• If one panel underperforms (due to dirt or shade), it affects the entire system
• Only allows system-level monitoring (you can’t see performance per panel)

What Is a Microinverter?

Microinverters are small inverters installed under each solar panel. They convert DC to AC directly at the panel itself.

Pros:

• Each panel works independently — better performance in shaded or multi-angle roofs
• Panel-level monitoring via app
• Maximizes total system output

 Cons:

• Higher upfront cost
• Slightly more complex installation

 Shading Performance: Big Difference

One of the biggest differences between microinverters and string inverters is how they handle shading.

String Inverter: If even one panel is shaded or dirty, the whole string's output drops
Microinverter: Only the shaded panel is affected, others continue to perform at their best

 That’s why microinverters are preferred for homes with trees, chimneys, or roof segments facing different directions.

Monitoring Your Solar System

Want to track your solar performance?

• Microinverters offer panel-level monitoring via app — ideal for tech-savvy homeowners or those who want precise control
• String inverters offer system-level monitoring, which shows only overall performance

Cost Comparison

• String Inverter System: Lower upfront cost. Ideal for homes with straightforward roof layouts.
• Microinverter System: Higher cost, but better efficiency and long-term returns, especially in challenging roof conditions.

Which One Should You Choose?
    

Situation	Best Option
Simple roof, no shading	String Inverter
Complex roof, partial shading, multiple angles	Microinverter
You want detailed monitoring	Microinverter
You want lower installation cost	String Inverter

   
 Final Thoughts: Ask the Solar Experts

Both microinverters and string inverters have their strengths. The best choice depends on your roof layout, shading, budget, and how closely you want to monitor your system.
