The solar industry is rapidly changing and evolving. As a result, training in this industry has to match that pace. We do regular material updates often.
Our material updated frequency is constant. We make corrections because we admit we don’t get it perfect first time around. We also update as products and codes evolve. As our textbooks are produced through “just in time” printing (no inventory), they instantly incorporate these changes.
We conduct a thorough scrub of our materials once a year. This ensures they are up to date. Every third year, we revise everything more in depth. We do this after the latest National Electric Code is published. This helps us incorporate any changes in the NEC.
