Sustainability > Singapore Aerospace Industry Solar Adoption Report 2023 > Report Methodology


SAISAR tracks solar PV installations in the Singapore’s aerospace industry.

  • The report focuses on aerospace companies in Singapore which are involved in maintenance, repair and overhaul (MRO) services, manufacturing, aftermarket services, as well as research and development (R&D) activities. It excludes companies in the air transport sector, such as airports, ground handling services, air cargo and airlines.
  • A survey was sent out to aerospace companies in mid-2023 asking for their participation. The companies surveyed either had facilities which they owned or leased. Tenanted facilities occupied by aerospace companies were also included, for example those participating in JTC’s rooftop licensing scheme. Aerospace companies housed in multi-tenanted facilities owned by non-aerospace entities were excluded from the survey.
  • Both company-owned and third-party owned (Power Purchase Agreement and roof top licensing) systems are included. The installations in this report represent systems operating as at the end of December 2023.
  • The questions in the 2023 survey were repeated from the 2021 survey. The report used data furnished by the companies which responded. Out of the 52 companies (based on their Unique Entity Number) invited to participate, 45 responded, giving a response rate of 86.5%. Of these, 32 respondents reported that they have solar deployments. We therefore estimate that this represents over 60% (32 out of 52 companies surveyed) of the aerospace industry.
  • Historical values have been revised with the incorporation of updated information from companies which were in the 2021 report. New information on earlier installations not reported in 2021, were also included. However, the additions arising were relatively minor.
