Frequently Asked Questions

Can SEI training count toward NABCEP requirements?

Yes, SEI courses are NABCEP-approved for training hours. Many professionals use SEI's PVOL101 and PVOL203 to fulfill the 58-hour requirement for PV Installation Professional certification.

How long does it typically take to prepare for NABCEP exams?

Most candidates require 3-6 months of dedicated preparation after completing training requirements. The NABCEP PVIP exam has a first-time pass rate of 68-72%, with significantly higher rates for those who complete exam prep courses.

Are there any prerequisites for SEI solar training?

SEI's foundational courses (PV101) require only basic math skills. Their more advanced courses typically recommend (but don't require) completion of prerequisite courses or equivalent field experience.

Which certification has better international recognition?

NABCEP is increasingly recognized in international markets, particularly for utility-scale projects. SEI's training is respected globally but doesn't carry the same weight as a certification. For international work, NABCEP plus local certifications often provides the best combination.

Can I get a job with just SEI training?

Yes, many residential solar companies hire candidates with SEI training, particularly when combined with electrical or construction experience. However, NABCEP certification becomes increasingly important for career advancement beyond entry-level positions.

Strategic Certification Planning

For maximum career benefit, consider this phased approach:

  1. Phase 1: Begin with SEI foundational training to enter the industry
  2. Phase 2: Gain 12-18 months of hands-on experience
  3. Phase 3: Pursue NABCEP certification to unlock higher-paying roles
  4. Phase 4: Add specialty certifications (battery storage, design, etc.)
