A system includes a containment vessel configured to receive and retain equipment to be decontaminated. The system also includes a solar reflector configured to reflect solar energy towards the containment vessel in order to heat the containment vessel. The system further includes end supports configured to receive and retain the solar reflector and the containment vessel. The system also includes a base having or coupled to multiple side supports, where each side support is configured to contact and support a corresponding one of the end supports. In addition, the system includes one or more semi-transparent solar shades configured to reduce the solar energy reaching the solar reflector and the containment vessel.
