String Inverter Market Expansion Drivers: What’s Shaping Future Growth?
The expansion of residential solar installations is projected to stimulate the string inverters market moving forward. Residential solar installations involve setting up solar panels on residential properties to generate electricity from the sun’s energy. String inverters are employed in both on-grid and off-grid systems, enabling users to supervise the system’s performance and health, which is consequently accelerating their adoption in the residential sector. For instance, in February 2023, according to Energy Live, a UK-based independent energy news provider, 73% of the UK’s new solar capacity stemmed from small-scale residential solar panel installations. The UK now boasts over 1,265,000 registered solar power installations, with approximately 1.1 million of these located on residential properties. Therefore, the growth in residential solar installations is propelling the string inverters market.
