Virginia Alternative Energy System Contracting Exam — Summarized Coverage
The Virginia Alternative Energy System (AES) Contracting Exam is administered through the Virginia
Department of Professional and Occupational Regulation and tests a contractor’s ability to install,
design, and maintain renewable and alternative energy systems in compliance with Virginia
contractor laws, building codes, and safety standards. The exam focuses on solar, wind, geothermal,
energy storage systems, electrical integration, and construction safety practices for residential and
commercial applications.

Virginia Alternative Energy System (AES) Contracting Exam Practice Questions
Batch 1 (Questions 1–50)
1. What is the primary purpose of the Virginia Alternative Energy System (AES) specialty contractor
classification?
A. To authorize contractors to perform general plumbing work only
B. To allow qualified contractors to install, maintain, and service renewable energy systems within the
specialty scope
C. To license architects exclusively
D. To perform residential painting projects
Correct Answer: B
, Page 4 of 126
Rationale: The AES specialty classification is intended for contractors who work with alternative and
renewable energy systems such as solar, wind, geothermal, and energy storage technologies in
accordance with Virginia regulations and applicable codes.
2. Which Virginia licensing class generally allows contractors to perform projects of the highest
monetary value?
A. Class C
B. Class B
C. Class A
D. Specialty licenses have no classifications
Correct Answer: C
Rationale: Virginia contractor licenses are divided into Class A, B, and C categories, with Class A
generally allowing the largest project values and requiring the highest financial and experience
qualifications.
