In mid-October, our team completed one of the most unique and inspiring projects in our portfolio to date. Set against the dramatic mountain backdrop of Grand Junction, Colorado, this system marks a major milestone for agrivoltaics in the U.S. by standing as the largest viticulture-focused agrivoltaic system (or “viti-voltaic”) in the country.

Back in 2023, University of California (UC) Davis had a small set of Sunzaun vertical bifacial racking installed – three rows of three modules – to support early agrivoltaics research. Sunstall donated so the university could begin exploring how vertical solar might work alongside crops in California farmland.
Two years later, and after immense collaboration, the research site looks quite different.
Sunstall is proud to celebrate the completion of its 100th solar project in collaboration with Coldwell Solar and OMCO Solar – a significant milestone highlighting the strength and consistency of a long-standing partnership.
Solar energy systems are evolving — not just in what they’re made of, but in how and where they’re installed. One innovative approach gaining attention is the use of vertical bifacial solar panels placed along the sides of irrigation canals.
At Sunstall, we help bring such systems into reality with mounting and engineering solutions — and with our product Sunzaun, we offer a purpose-built vertical PV solution that’s ideal for these kinds of applications. Read more
The Challenge
As the world’s population continues to urbanize, the demand for energy in cities is growing rapidly. The electrical demand in urban areas in California is expected to increase by 30% in the next 10 years. This increase is being driven by a number of factors, including:
- The growth of the population in urban areas
- The increasing use of electric vehicles
- The shift to heat pumps
Our solar fastening Dilemma – Where are we coming from?
The global solar market is growing and so is the pain of dealing with nuts and bolts as the standard method to connect an assembly. To review why Nuts & Bolts are holding the solar industry back visit : Torquing – the Solar Installation Mystery!
It’s been almost 5 years since I wrote this article being frustrated with the lack of quality and other related issues, such as:
- supply chain issues – procuring nuts and bolts in bulk guarantees inventory issues
- manufacturing issues- ordering an M10 and getting an DIN M10 bolt are two different things – oh – and btw the nut should match the bolt.
- losing nuts and bolts in harsh conditions is a given! Try installing them with gloves in NY at 20 degrees Fahrenheit.
- and then you have the discussion about the torque – if interested read my first article. See video below and you see what I am referring to.
Loosely speaking, torque is a measure of the turning force on an object such as a bolt – and as Dan Shugar, CEO of Nextracker stated : “Torquing is by nature inexact because of the many factors that can affect friction – from surface texture to debris, rust and humidity”*. In this article I will try to shed some light into the mysterious world of torquing in the solar installation world.

The project is being developed under MCE’s Feed-In Tariff, a standard offer contract for local renewable projects. The Cooley Quarry project will supply Local Sol customers with brand new 100% solar energy.
Nothing new about the fact that productivity is key…
…, but why is everybody just talking about how fast a system can be installed and seemingly only looking at the manufacturer’s marketing flyer?
Productivity/installation speed, and therefore the price of a large PV install, is impacted by multiple factors including:
Mounting Systems Integrates Sigma I Steel Ground Mounts into a 4 MW Photovoltaic Project
June 8, 2016
West Sacramento, CA – In light of the recent completion of a 4 MW PV project in Livermore, CA, Mounting Systems is proud to announce its contribution to the success of this solar development at the Lawrence Livermore National Laboratory (LLNL). Mounting Systems supplied its signature Sigma I Steel ground mounts, which utilizes a new, proprietary cold-rolled steel with Clickstone technology for speed and ease of installation. With ISO-9001 and UL 2703 certification, contractors could depend on the efficiency and reliability of ground mount installations through Mounting System’s services. Read more
