(Reuters) - Elon Musk-led Tesla Inc has missed its solar-roof installation targets by a massive margin due to stiff competition from GAF Energy and other rivals, according to industry analysis firm Wood Mackenzie.
Tesla's average installations per week were just 21 in 2022 and its best quarter saw 32 systems installed per week.
That was far lower than the company's 1,000-per-week target for 2021. Musk had not provided a forecast for 2022.
"GAF Energy's Timberline Solar roofing system is better-positioned to achieve widespread adoption," said Max Issokson, analyst at Wood Mackenzie.
The potential of Tesla's Solar Roof will rely on the company's ability to simplify and streamline installations and tap into a broader customer base, Issokson added.
Tesla said in January it had more than 85 installation partners.
Tesla, the world's most valuable automaker, acquired SolarCity in 2016. At the time, Musk aimed to create a solar product that would generate power through solar panels on roofs and store energy in batteries.
That was in contrast to most other solar roofing companies, which only sell and install the solar panels.
Tesla's combined energy-generation-and-storage solution deployed at several houses and commercial applications has withstood strong winds and hurricanes.
Wood Mackenzie had earlier said that SolarCity captured a third of the solar panel market in 2015, after which Tesla's share decreased to about 0.2% in 2021.
