Boosting Yield for Utility-Scale Solar Assets: A Small Step That Saves Big

A Small Step That Saves Big: PV Module Testing can safe money, trouble and more when going live

Performing module flashing tests on-site is a crucial step to ensuring the quality and performance of photovoltaic (PV) modules. Our experience from numerous projects has shown that these tests help verify that delivered modules meet expectations and contract specifications—saving investors from costly surprises.

🔎 Why It Matters:

During recent tests for a client, several out of 800 modules were found to be defective. Without testing, these faulty modules would have been installed—leading to reduced energy generation, financial losses, and increased risk for investors. By identifying and replacing defective modules before installation, we protect the system’s performance and long-term profitability.

📌 Two Ways to Test Your PV Modules:

1. On-Site Flash Tests

To confirm that suppliers deliver PV modules with the agreed power output, we conduct on-site flash tests. This involves selecting random samples of modules for measurement, followed by in-depth statistical analysis. These tests ensure compliance with agreed specifications and help mitigate risks before systems go live.
