These are real pages from the book. The table of contents is the full one: 9 parts and 64 topics.
You're on a roof with the inverter and the MLPEs already in, and the inspector asks what voltage is left inside the array boundary after someone hits the initiator.
You read 690.12 last night. The code puts it all in one dense block: boundary, conductors, voltage limits, listings, exceptions, one line after another. Nothing in there shows you what to picture.
In the book, rapid shutdown is one page. The array boundary is drawn as a line around the modules: 30 V or less outside it, 80 V or less (or a UL 3741 listed system) inside it, and a clock that says 30 seconds.
Same with cold Voc, the 120% rule, grounding vs. bonding, the required labels and commissioning: each one has its own page, with the NEC section printed next to the drawing.
You see it, you understand it, and you answer the inspector without flipping back through the Code Book.
The system as one path, string sizing, current and OCPD, disconnects and rapid shutdown, grounding, interconnection, storage and safety, commissioning and exam review: 68 pages, all illustrated
Think of it this way:
It's 9 p.m., two weeks before your PVIP exam. A practice question gives you a 49.5 V module, a −10 °C design low and a −0.28 %/°C coefficient. You need the cold Voc before you can count modules per string.
You open page 14 and the steps are drawn in order: −10 °C minus 25 °C is −35, times −0.0028 gives +0.098, and 49.5 V × 1.098 = 54.35 V per module, with 690.7(A) printed right beside it.
Same with rapid shutdown, the 120% rule, grounding vs. bonding, the required labels and commissioning: each one on its own page.
Solar PV Installer Illustrated is 9 parts and 64 topics, all drawn, and it closes with an exam review: every formula on one page, round up or round down, and an exam-day checklist.
What you see drawn, you don't have to memorize.
The whole system from the cell to the utility meter, reading a datasheet, temperature coefficients, series vs. parallel, string, micro or optimizer, bypass diodes and where each rule lives in the NEC.
String sizing in 5 fixed steps: design low temperature, cold Voc with the coefficient or Table 690.7(A), max and min modules per string, parallel strings and DC/AC ratio.
Isc × 1.25, the second 125%, why 125% and 120% are different rules, 75 °C terminals, rooftop and conduit fill corrections, string fuses, the output breaker and voltage drop.
The PV system disconnect, equipment disconnects, the array boundary, 80 V and 30 V in 30 seconds, the initiator and its label, arc-fault and ground-fault protection.
Grounding vs. bonding, sizing the EGC, bonding frames and rails, the electrode and GEC, functionally grounded arrays and protecting a small exposed EGC.
Supply side or load side, the 120% rule step by step and worked on a 200 A panel, opposite end, downsizing the main, the 100% sum rule, supply-side taps and anti-islanding.
AC- vs. DC-coupled storage, Article 706 basics, battery sizing, roof attachments and flashing, fire access pathways, fall protection and why DC is live in daylight.
Commissioning in a fixed order: polarity and Voc, Isc against irradiance, insulation resistance, every required label on one map and troubleshooting a low string.
What the PVIP exam covers, every formula on one page, round up or round down, the most frequent mix-ups, an exam-day checklist and the whole path recapped.
At the end of the book: An exam review part with every formula on one page, round-up rules and an exam-day checklist.
Exam-style questions on string sizing, conductor sizing, the 120% rule and rapid shutdown, each answer worked step by step so you see exactly where you went wrong.
The most frequent errors on the roof and in the calculations, each drawn wrong and then right, so you can review them in one sitting before the exam.

You already know wiring. The book shows you what changes on the DC side: cold Voc, rapid shutdown and the 120% rule, each drawn with its NEC section.
You review one topic per page at night, with every calculation solved in the same fixed steps, and finish with every formula on one page.
You know how to do it on the roof. The book draws the why, so you can explain it to the inspector, to your crew and on the exam.

Yes. It doesn't explain what a panel is. It goes straight to what the exam asks: string sizing, conductors and OCPD, rapid shutdown, grounding, interconnection, storage and commissioning, each drawn on its own page. The Code Book gives you the rule in text; here it's drawn, with the NEC section beside it, and every calculation is solved in the same fixed steps.
From the NEC 2023 (NFPA 70), Articles 690, 705 and 706 plus 110, 250 and 310, cross-checked against the NABCEP PVIP Job Task Analysis. Before your exam, check which NEC edition NABCEP lists in its current Candidate Handbook. On the job, your state may have adopted another edition, and your AHJ can add local amendments.
No. It's an independent illustrated study guide, not affiliated with NABCEP or NFPA.
No. It's a study and review book. It doesn't count toward NABCEP training hours, it doesn't give you a certificate, and it doesn't replace your field experience or the Code Book itself.
No. They are written for this book, in exam style, with each answer worked step by step. They are not official NABCEP questions.

No. It's a one-time payment. No subscription.
Yes. The PDF is printable, so you can print it at home or at a print shop and keep it in the truck.

No more rereading the code with nothing sticking.
Rapid shutdown: you see it drawn, and that's it.
You walk into the PVIP exam knowing where every rule lives.
