About this file
This document contains the results of three solar glare analyses conducted using ForgeSolar software. The analyses evaluated a fixed-tilt photovoltaic array located at various coordinates in the Virgin Islands for glare impacts on aircraft flight paths and observation points. No glare was predicted in the second and third analyses, while the first analysis predicted low potential for temporary after-images. All analyses noted a diffuse normal irradiance varying and peaking at 1,000 W/m^2, with evaluations conducted every minute using specified eye and aircraft parameters.
This related federal contract opportunity is a solicitation for renewable energy systems in the Virgin Islands. The Department of the Army Michigan Army National Guard is seeking proposals with a submission deadline of an unspecified date. Offerors are instructed to submit to an address at Selfridge Air National Guard Base in Michigan. Site visits to bases in St. Croix are also referenced. Relevant details include the solicitation number, opportunity type, agency involved, and modifications to include design specifications and points of contact for base access.
