Museum of Flight Installed Large Solar Array

Live Poll

Do you believe solar power is a reliable energy source for large buildings in your area?

The Museum of Flight in Seattle has installed 1,863 solar panels on the roof of its Aviation Pavilion. The system is designed to provide 1.08 megawatts of energy to help power the museum's West Campus.

Why it matters

This installation supports the organization's goal of powering its entire West Campus with 100% solar energy. It also demonstrates the use of locally manufactured technology to meet institutional sustainability targets.

The new system utilizes 1,863 individual panels, each weighing approximately 60 pounds, to cover a roof area exceeding two football fields. This setup features a metering process to return excess summer energy to the electrical grid for credits.

The players

Museum of Flight

This Seattle-based non-profit organization maintains one of the largest air and space collections in the world.

Washington State Department of Commerce

This state agency works to strengthen communities and promote economic vitality through various funding and infrastructure initiatives.

Silfab

This Washington-based manufacturer specializes in the production of high-efficiency solar photovoltaic modules for residential and commercial markets.

The details

Washington-based Silfab manufactured the panels, which were hoisted onto the pavilion roof via crane. The project, which covers an area larger than two football fields, is aimed at securing renewable energy independence for the site.

December 2026: Estimated completion date for the panel installation.

Deeper Dive

The museum's installation follows a pattern established by the Washington State Department of Commerce energy infrastructure funding initiatives, which seek to incentivize commercial renewable adoption.

This project could lead to lower long-term operating costs for the museum by leveraging summer energy credits through the regional grid. The integration of local manufacturing may also serve as a blueprint for other large-scale institutions in the region to upgrade their facilities.

The takeaway

Large-scale solar adoption can provide significant energy independence for major facilities by utilizing excess capacity during peak generation months. Implementing such systems requires careful logistical planning, such as using cranes for heavy panel placement on expansive roof surfaces.
