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 learned a lot from this course

by Ole Marius Svendsen 11/15/2022

I greatly appreciate someone who talks on the actual simulation and overall design of PV system. Unlike other courses, they all talk hallelujah on how environmental PV are, tho never in depth on different design choices and the impact on the overall performances.

I've used helioscope for quite a while and this course gave insight into less known methods and methodology for creating an accurate and efficient system

Improve your design now! Lots of material, best explanation on Voltage Losses(Under/Over), Temperature Losses(Racking), module Efficiencies and system Mismatches
