String inverters are the less expensive, but photovoltaic experts often recommend micro-inverters, due to their many other benefits and advantages.
No. 1: Faster Solar Energy System Installation
Micro-inverters are individually attached to each of the photovoltaic panels in your home solar power system. Since the panels aren’t wired together in strings, the solar energy installation process is often faster — which translates to savings on labor charges.
No. 2: Less Visible Solar Energy Equipment
String inverters are typically installed close to the utility meter, either inside the garage or outside of the home. Some models take up a lot of valuable space, and most are rather unsightly. With micro-inverters, most of the solar equipment is up with the photovoltaic panels, out of view.
No. 3: Greater Solar Energy System Efficiency
With a string inverter, damage or shade on one of the photovoltaic panels decreases the energy output of the entire system. Micro-inverters are much more efficient and reliable — you don’t have to worry about losing all your electricity production if one module underperforms.
No. 4: Precision Photovoltaic System Monitoring
If you install a string inverter, you’ll be able to track the energy production of your home solar power system as a whole. With micro-inverters, however, you can monitor the electricity output of each individual module. And using a web-based monitoring system, you can see how each of your photovoltaic panels is performing from anywhere.
No. 5: Easy to Expand a Home PV System
Do you think you might want to add on to your solar power system at some point? Some homeowners start with smaller photovoltaic arrays and expand them later, as their budget allows. If you’d like that option, you may want to install micro-inverters to make expansion easier.
No. 6: Extended Solar Warranty Coverage
Warranties for string inverters offer coverage for about 5 to 10 years, as these parts can wear out by that time. Micro-inverters, on the other hand, typically come with 25-year warranties because of their longer life spans. If you want photovoltaic components that last, you’ll want to choose micro-inverters.
The professionals at Intermountain Wind & Solar recommend micro-inverters for many home PV system installations, but string inverters are a smart choice for many homeowners. The decision comes down to your needs and preferences — our team can design an efficient, cost-effective photovoltaic installation with either type of inverter.
