    January 28 (Renewables Now) - Tesla Inc (NASDAQ:TSLA) this week reported results for 2021, showing a 68% year-on-year jump in solar installations and a 32% increase in energy storage deployments to almost 4 GWh.

    Last year, the company installed 345 MW of solar systems, significantly more than in 2019 or 2020, but still below the 2017 level of 523 MW. Tesla said cash/loan purchases accounted for almost all of the solar systems installed in 2021. Solar Roof deployments have tripled when compared to 2020, but the company did not reveal specific capacity figures.

    Storage systems deployment reached 3,992 MWh, mainly thanks to strong interest in the Megapack large energy storage product. Demand remains greater than capacity and growth in the segment has been limited by supply, Tesla said.

    The company is building a Megapack factory in response to the strong demand.

    The table contains more details on deployments.
