Dear Sunstall partner,
It’s been ten years in the making and we are thrilled to have reached this milestone, with you by our side.
From Hawaii to Massachusetts, Sunstall has been there to bring solar to the reaches of the US. Continuing forward, our mission is to sunstall solar in evermore States, proliferating reusable energy, and carrying forward our key partnerships.
A decade of Sunstalling is just the beginning! We look forward to the next ten years and to the growth to come.
Having many other uses, steel piles are often used to build the foundations for utility-scale PV applications. In use, they become exposed to different types of corrosion of various extents. Some of the main elements that impact the level of corrosion are pile shape, driving method and the type of material. Common shapes include H-piles, pipe-piles, screw piles and disc piles – all of which can have different material types. H-piles have become the most used for solar structures, because they have very good structural characteristics. This allows them to be well-suited for the loads seen in solar installations.
In general, corrosion takes place when two different metals come into contact with a conductive liquid, resulting in a flow of DC electricity. Pile corrosion can be divided into two groups: Atmospheric and soil corrosion.

Pile Load Testing helps to reduce cost and avoids economic losses if interpreted the right way. Sometimes project developers are getting the sticker shock when they hear the price for a load test, especially when it is a small project where the cost impact is high. Let’s us convince you that it is in your best interest that this is done professionally with the proper procedures. One single workflow will provide you multiple benefits for your project. Read more

Pile driving quality goes to the very foundations of a PV array, quite literally. Helge Biernath, CEO of Sunstall, speaks to pv magazine about the importance of getting the foundations and footings of a PV array right. In this, being mindful of the weather, Biernath notes, is a vital factor.
From the perspective of an installer the better the planning and the better the execution matches the planning the better the end result and the less likely it is that CO’s will be issued! Sounds easy – should be easy, but in reality….. it is not that easy!
If a project is executed on the fly – the costs have to be higher than well planned & executed projects so therefore the contingency has to be higher!
Check out the presentation to get some ideas how to reduce costs & call us to discuss and support your project!
