voltage calculations

SolPowerPeople is excited to announce that Rebekah Hren, NABCEP Certified Solar PV Installer, licensed electrical contractor, and IREC/ISPQ Certified Affiliated PV Instructor, will present a lecture on Array Voltage Calculations and Considerations on April 4. This lecture is part of a line-up of lectures presented to help those preparing to sit for the very difficult NABCEP Certified PV Installation Professional Exam, and will offer a clear perspective of voltage considerations important for safe, high performing PV system design. Date and time: Thursday April 4, 4PM Pacific, 6PM Central, 7PM Eastern

Registration is open for this #SolarMOOC lecture with PV expert Rebekah Hren: Anyone who is interested in assuring that a photovoltaic system achieves maximum performance while remaining safe and code compliant will benefit from this lecture. Register Here to attend the April 4th lecture to be held live online at 4PM Pacific, 6PM Central, 7PM Eastern.

Rebekah HrenRebekah Hren will offer her expertise in solar photovoltaic system design this coming Thursday, April 4th in an effort to dispel confusion on the correct way to calculate maximum and minimum system and string voltages for best system design.  Rebekah will offer a walk through of what important factors must be taken into consideration, and how to apply them in sytem design formulas in order to properly perform one of the most critical aspects of system design.

This is one of those things that system designers often use software tools for, such as PVSYST, and that those desiring to achieve NABCEP PV Installation Professional Certification should know how to do manually.  Whether you are trying to gain your NABCEP certification or just be prepared in case of a software failure, this lecture will be invauable in helping you to understand array sizing through voltage considerations.

Rebekah Hren is coauthor with her husband Stephen of “The Carbon-Free Home: 36 Remodeling Projects to Help Kick the Fossil-Fuel Habit”, and lives sustainably in a modified 1932 home that with hard earned skills, love, and sweat equity they have turned in to a model zero-carbon home.
