String solar inverters are the most widespread type of inverter around the world. According to IHS Markit 2020, in 2019 they occupied more than 60% of the whole market
. String inverter is grid-connected and can take care of a row of solar panels, which are considered as one string. The main disadvantage of a string inverter is its inability to cope with problematic panels: if even one panel in a row suffers from shading or is damaged and has lower efficiency as a result, it usually drags down other panels in a row to its level. However, string inverters are relatively inexpensive and reliable, which probably explains their popularity. Some models have advanced features that make interaction with the device so much easier.
