About this course

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
