Which specialty contractor license is required to install solar photovoltaic systems in Hawaii?

Correct Answer

B) C-46 (Solar)

Hawaii requires a C-46 (Solar) specialty contractor license for the installation of solar photovoltaic systems.

Answer Options
A
C-17 (Glazing)
B
C-46 (Solar)
C
C-27 (Landscaping)
D
C-16 (Fire Protection)

Why This Is the Correct Answer

Hawaii's contractor licensing system includes the C-46 (Solar) specialty license specifically for the installation of solar photovoltaic (PV) systems. This dedicated license category reflects the significant growth of solar installations in Hawaii, which has one of the highest rates of residential solar adoption in the nation.

Why the Other Options Are Wrong

Option A: C-17 (Glazing)

C-17 (Glazing) is for glass and glazing work — windows, storefronts, and similar transparent enclosures. It has no relationship to solar photovoltaic systems, which involve electrical generation equipment, mounting hardware, and inverters.

Option C: C-27 (Landscaping)

C-27 (Landscaping) covers lawn and garden installation, irrigation, and related outdoor landscaping work. It is entirely unrelated to electrical or solar energy systems and would not authorize any solar PV installation work.

Option D: C-16 (Fire Protection)

C-16 (Fire Protection) covers fire suppression and sprinkler systems. While fire safety systems and solar installations may coexist on a roof, the C-16 license does not authorize solar PV installation work.

Memory Technique

C-46 = Solar: think '46' as in the 46th state — Hawaii was actually the 50th, but picture the tropical sun shining on the islands. Or simply: 4 + 6 = 10, and there are 10 letters in 'PHOTOVOLT' (approx.) — just link C-46 directly to the sun and solar panels as a flashcard pair.
