If you’re preparing for the Hawaii Solar Power Systems Contractor (C-60) trade exam, one of the smartest things you can do is study using the exact book you’ll have access to during testing. This package is built around the National Electrical Code (NEC), 2020—the reference PSI provides in the testing center for the C-60 exam. That matters because C-60 is a timed, open-book exam where your success depends heavily on how quickly you can locate the right article, table, definition, or exception and apply it correctly.
The C-60 classification covers the work of assembling and installing photovoltaic panels, batteries, controls, and related low-voltage DC wiring. On the exam, you’ll see questions that test photovoltaic theory, system components, installation practices, and jobsite safety, along with a significant portion on estimating, calculations, and design. Even when you know the concepts, you still have to execute under time pressure—finding the correct NEC section quickly and avoiding common traps like missing exceptions, overlooking definitions, or applying the wrong table.
This is why a “books allowed into the exam” package is different from a general book bundle. The goal is not to overwhelm you with extra resources you can’t use on exam day. Instead, it’s to help you build NEC navigation speed and exam-focused confidence so you can handle the most common C-60 tasks:
Studying with the NEC isn’t about memorizing pages. It’s about building a reliable method. Candidates who perform well on timed open-book exams train a repeatable process: identify → locate → verify → apply. This package supports that approach by focusing your preparation on the reference you’ll have available at the testing center.
Another advantage: practicing with the NEC improves your real-world readiness. Solar work doesn’t happen in a vacuum. PV systems interface with electrical requirements, installation practices, inspection expectations, and safety standards. Learning how to use the NEC efficiently is not just exam prep—it’s a professional skill you’ll carry into the field.
This package is intentionally focused on the book that PSI provides in the testing center for the C-60 exam. That allows you to study in a way that matches the exam environment and build confidence that your prep aligns with what you can actually use on test day.
The Hawaii C-60 Solar Power Systems Contractor trade exam is structured as follows:
The content areas and item counts for C-60 are:
This breakdown is extremely useful for planning your study time. The largest slice of the exam is Estimating, Calculations, and Design, followed by Photovoltaic Components and Electrical Interconnection. A strong strategy is to spend consistent time building comfort with calculations and design thinking while also developing steady, repeatable NEC lookup habits.
Because the exam is timed, “knowing” the NEC is only part of the equation. You also need to be able to move through it efficiently. That’s what transforms open-book exams from stressful to manageable: you don’t waste time searching—you go directly to the right place and confirm what you need.
The Hawaii C-60 Solar Power Systems Contractor exam is an OPEN BOOK examination. The testing center provides the National Electrical Code (NEC), 2020 edition for your use during the exam, and no highlighting or notes may be made in the book during the exam.
It’s also important to know what “open book” means in practice for C-60:
So how do you use an open-book format to your advantage? You train for it.
Open-book contractor exams are not designed for leisurely reading. They’re designed to test whether you can retrieve and apply correct information quickly. That’s why working from the NEC—the book you’ll have access to—can be such a practical advantage. As you practice, you’ll start building your own “mental map” of where common topics live:
That navigation skill is what reduces second-guessing and improves speed. When you can confirm details quickly, you stay calmer, manage time better, and answer more consistently.
Hawaii contractor licensing is administered through the State of Hawaii Department of Commerce and Consumer Affairs (DCCA), Professional and Vocational Licensing (PVL) division, Contractors License Board. Examinations are administered by PSI Services, LLC. A typical pathway for trade exam candidates generally looks like this:
One timeline detail you should plan around: eligibility to test is valid for six (6) months, and you may test multiple times within that six-month period. If you do not pass within six months, you must reapply by filing a new application.
Because timing matters, a practical approach is to start building your study momentum early, then increase intensity after you receive authorization to test. That keeps your preparation efficient without risking the stress of a last-minute cram.
The Contractors License Board requires applicants to be approved before they are allowed to register for the examination. After Board approval, you will receive an approval notice indicating which exam(s) you are eligible to take and the date by which the exam(s) must be passed.
Since licensing requirements can vary by applicant type and can change over time, your most reliable step is to follow the current Hawaii application instructions issued through the DCCA PVL Contractors License Board. While you’re working through that process, you can keep moving forward by focusing on what you can control right now:
The best candidates don’t rely on memory alone. They train a system for finding and verifying information under time pressure.
For the Hawaii C-60 Solar Power Systems Contractor exam, the National Electrical Code (NEC), 2020 edition is the reference provided in the testing center for use during the exam. Other common solar/electrical references are listed as not allowed in the examination center for C-60, so this package is intentionally focused on the NEC.
To prepare effectively for the C-60 exam, your study should match the exam environment: timed, open book, and centered around the NEC. The most productive preparation doesn’t look like passive reading. It looks like active practice.
Here are study methods that work especially well when your exam-day reference is the NEC:
As you practice, track what slows you down. Your “slow list” becomes your best study plan because it’s tailored to your performance. Each week, shrink that list by revisiting those topics with timed drills.
Finally, practice your exam pacing. With 50 questions in 120 minutes, you have an average of just over two minutes per question. Some questions will take longer because they require deeper code lookups or multi-step reasoning. That’s normal—but it makes a disciplined strategy even more important:
When you train that pacing ahead of time, the exam feels more controlled and less stressful.
1 Exam Prep supports candidates by focusing on preparation that fits how trade exams actually work—organized study, reference navigation habits, and practice-oriented training. For the Hawaii C-60 exam, that means helping you build skill with the reference you can use during testing: the NEC (2020).
This package supports your progress in practical ways:
We never guarantee outcomes—passing depends on your preparation and meeting Hawaii’s licensing requirements—but we do focus on giving you a realistic, trade-aligned way to prepare so you can approach the C-60 exam with better execution and stronger confidence.
