Personal study access

$25 per lesson plan, one-time payment. Each IEC year, master test, Solar PV plan, AIR 360 course and NABCEP track is purchased separately for one student. No subscription or automatic renewal.
24-hour free trial by code. One trial covers all Classroom plans. Its clock starts only when you redeem a valid code. Sign-in alone gives no free study access, and the trial never authorizes a charge.
Individual accounts. Use your own account. A new sign-in ends your previous Classroom session. Trial codes activate a personal trial; they cannot transfer an account or paid access.
Payment activation. Pay through QuickBooks by card or bank transfer. Eclipse Solar assigns the purchased plan to your account after confirming the completed payment. A receipt claim or checkout return cannot open the app.
Original practice material. Do not share sign-in links, redistribute, resell or publish study software or question banks without written permission from Eclipse Solar LLC. Public facts, government sources and third-party standards remain subject to their own rights.

Your email and account ID support sign-in and enrollment. Study progress stays in this browser, separately for each student and plan. Export a progress backup to move it to another device.
