Course description

Designed by the makers of HelioScope, this course will introduce students to some of the most common questions and issues of solar performance modeling. With this knowledge, good design choices can be simplified and included to improve any pitch.

In this course you will gain basic working knowledge to deal with:
- Choosing appropriate weather files for simulated production
- Understanding the value of TMY files
- Creating Pxx Production Estimates
- Selecting PAN files for module simulation
- Evaluating Loss at Irradiance
- Considering temperature losses in your designs
- Considering mismatch losses in your designs
- Considering over/undervoltage losses in your designs
- Evaluating Performance Ratios and kWh/kWp
- Understanding the meaning of module efficiency

I have been using helioscope daily for over a year and this course has helped me understand the numbers better.

by Rehan Siddiqui 04/19/2021

Totally recommended to anyone engaged in solar design. Short, to the point, filled with quality information and great charts/graphs.. Excellent Value.

by Willem Stefanus Marais 03/10/2021

Really helps to answer a lot of the questions I had in regards to designing a pv system on helioscope. New to the field of pv and found it intuitive from an engineering view point.

by Srikar Boddukuri 02/13/2021

This course is very useful and effective to those who want their career in the Solar domain by gaining deep insights.
