The Leading Growth Driver In The String Inverter Market Explained
The anticipated rise in residential solar installations is projected to fuel the string inverters market moving forward. These installations involve the placement of solar panels on residential properties to generate electricity from the sun’s energy. String inverters find application in both on-grid and off-grid systems, providing users with the facility to monitor the system’s performance and health, which is consequently boosting their uptake in the residential sector. For instance, in February 2023, as reported by Energy Live, a UK-based independent energy news provider, 73% of the UK’s new solar capacity originated from small-scale residential solar panel installations. The UK currently has over 1,265,000 registered solar power installations, with approximately 1.1 million of these situated on residential properties. Therefore, the expansion of residential solar installations is a primary driver for the string inverters market.
