• Total deployed solar capacity by the aerospace industry
    (as of June 2021)

  19.65 MWp

A total of 14 solar projects were implemented in the period 2013 to 2020, with an annual average growth rate of 83.6% in solar capacity. The implementation peak was in 2015 with 6 projects generating a total of 6.63 MWp capacity. 1 Megawatt-peak (MWp) is the nominal power rating achieved under ideal solar irradiance conditions, and is equivalent to the maximum power generated by 3,333 solar panels each with a rating of 300W.

The industry’s solar adoption looks set to grow incrementally. From the survey feedback, there are 3 projects scheduled to be operational in 2021 and a potential pipeline of 12 additional projects, i.e. the companies have indicated interest to install solar panels in the near future.

The installed capacity of 19.65 MWp accounts for 4.4% of Singapore’s total solar capacity of 443.60 MWp[2]. If we are looking at just the non-residential private sector installations in Singapore as the base, the aerospace industry’s installed capacity would account for 8.3%.

This is a noteworthy sectoral achievement, bearing in mind that the aerospace industry accounts for a proportionately smaller 1% of Singapore’s Gross Domestic Product (GDP)[3].

  • Total electricity produced annually

21.18 million kWh 

  • Solar energy as share of respondents’ overall energy consumption


The contribution varies from 4% to 95% across the companies that have deployed solar energy, in view of the amount of rooftop space available and the nature of their operations. 10.7% is a weighted average.

  • Amount of building, hangar and car park roof space used

123,053 sqm

This is the amount of space — equivalent to 17 soccer fields – that has been repurposed for economic and environmental benefits.
