Warranty for DTS Mini-Max
The “Warranty Terms” are not merely a standard attachment to the sold device. This is a document that carries both responsibility and significance for how the manufacturer is perceived. That is why it is crucial that every statement included is justified by R&D work conducted on the product and based on well-established knowledge about the components used.
Below is a comment by Mr. Radosław K. regarding my proposal to include Dual-Axis Solar Trackers (DTS) in the publication “What PSE Can Do”:
“You can’t cheat physics – every mechanical part will wear out: every connection, every friction element, every drive, every piece of electronics.”
This shows impressive care for the investor (or perhaps an uninformed advisor?). That is why I feel obliged to thoroughly present the R&D efforts behind our product and the conclusions that form the foundation of our warranty policy. In our view, the common issues observed in widely used DTS systems don’t result from “intensive” operation, but rather from the nature of that operation. While the drives used may be technically sound, they often fail due to mechanical overload. This led us to develop our patented A.S.N.T. – Active Solar Tracker Drive System.
East–West Drive
-
Slide bearing – In systems I’m familiar with, it runs at approx. 90 RPM and lasts around 10 years. In the DTS, it performs just 1.5 revolutions per day – about 500 per year. Theoretically: around 5,000 years before natural wear.
-
Tapered roller bearing – A similar calculation, but the result is even more surprising: it performs more revolutions in a single minute in typical devices than it does in a full year in our tracker. Theoretical durability: around 1 million years.
I won’t elaborate further, as it borders on the absurd. I simply ask for logical reasoning and leave it to the realm of dreams that I will one day witness the first failure of these components in our DTS testing units.
(For those interested – though perhaps not exciting to laypeople – detailed technical descriptions are available on our website.)
Our R&D and Warranty Philosophy
Our over four years of R&D include more than three years of real-world operation of DTS Mini-Max generating energy, and over sixteen years of simulated operation during nighttime testing. Based on this, we confidently offer the following warranty terms:
✅ 10 years of full warranty coverage on the entire DTS system
✅ After this period, the warranty may be extended annually, at a cost of just 0.02 PLN per kWh generated
