I used to train installers of (mostly residential) PV systems, and tell them that half of the quality of a PV system is in good materials and design, and the other half is in proper installation. For utility solar systems there is even a “third half” (if there is such a thing); maintenance!

A good measure of the quality of a PV plant is the Performance Ratio: it separates “the good, the bad and the ugly” solar systems from each other. Find out more in our whitepaper: 6 key influences that determine PV performance ratios.

In most PV plant monitoring software you can choose the definition of the Performance Ratio (PR). So, a specific PV plant can have different Performance Ratios at the same time? Yes, and no…

Puzzled? Is Performance Ratio misleading? You don’t have to be puzzled, and no, Performance Ratio is not about misleading, it is about facts! Read our whitepaper – 6 key influences that determine PV performance ratios – to get a better understanding.

Since starting at Kipp & Zonen and my first encounter with solar energy in 2015 the industry has been booming. Although important strides have been made, the industry continues to struggle with some basics as it develops into maturity.Many practical issues such as “how should I wire my solar panels across the plant?”, “how many pyranometers do I need?” and “when should I clean my solar panels?” are still not well answered. For me, this last question particularly struck a spark of inspiration; there seemed to be room in the market for finding new and simple solutions.
