Interview with Cristian Croitoru, Business Development Representative at J Systems.
How do your products or solutions contribute to greater operational efficiency for your clients or end-users?
Cristian Croitoru: Our photovoltaic and agrivoltaic mounting systems are engineered for fast installation, optimal land use, long-term structural stability, and minimal maintenance. These characteristics reduce installation time, lower operational costs, and ensure stable energy performance throughout the lifetime of the system.
Moreover, since many of our fasteners are pre-assembled, using our products can significantly accelerate on-site construction and improve overall installation efficiency.
Which key technologies or design principles have most improved the efficiency of your latest product generation?
C.C: Our greenhouse and agrivoltaic designs not only enhance crop productivity but also generate electricity simultaneously, delivering dual benefits for agricultural and photovoltaic output.
How do you define and measure “efficiency” within your organization or product portfolio?
C.C: Efficiency is measured through installation speed per kW, mechanical resistance relative to material use, lifetime cost of the structure, and actual field performance. Stability, low maintenance requirements, and predictable long-term behavior are core indicators used in our evaluations.
In what ways has digitalization (IoT, data analytics, AI, etc.) influenced your approach to improving efficiency?
C.C: We use structural simulation tools to validate and optimize the geometry of our mounting systems. These tools allow us to analyze mechanical behavior under wind and snow loads and to adjust the profiles for an optimal strength-to-weight ratio. This digital validation reduces development time, minimizes material use, and ensures consistent structural performance before production.
Having said that, we value the importance of the field-testing as well. All our products have been proved very resistant by so many projects with different applications.
Can you share a recent project or case study where efficiency gains led to significant performance or sustainability benefits?
C.C: A 150 kW agrivoltaic pilot project implemented in Romania in 2025 demonstrated strong dual benefits: grape production of 8 t/ha under panels versus 2.5 t/ha in an open field, improved soil moisture retention, reduced wind exposure, and renewable energy generation without compromising agricultural output. The project validates the efficiency of combining energy and agriculture on the same land.
How do you balance efficiency improvements with other priorities, such as reliability, quality, or environmental impact?
C.C: We focus on material durability, structural integrity, and design simplicity. Zn-Al-Mg steel extends product lifetime and reduces material consumption. Agrivoltaic systems support sustainable agriculture by improving microclimate stability, lowering irrigation needs, and minimizing land conflict between food and energy.
What role do your suppliers or partners play in helping you achieve higher efficiency across your value chain?
C.C: We work with certified steel suppliers and internationally recognized module manufacturers. Their material consistency, dimensional accuracy, and stable delivery schedules contribute directly to faster installations and predictable project outcomes.
How do you ensure that efficiency improvements are maintained over the full lifecycle of your product or solution?
C.C: Our systems are modular, easy to inspect, and built from corrosion-resistant materials. This ensures long-term mechanical stability and sustained operational efficiency with minimal intervention.
What challenges or barriers do you face when implementing efficiency-driven innovations in your industry?
C.C: Different regional standards, emerging agrivoltaic regulations, and the lack of long-term agricultural performance data represent the main challenges. Continuous testing, adaptation to local conditions, and collaboration with research partners are essential to overcome these barriers.
That’s why we invested in Romania the agrivoltaics project with local partners to observe the actual performance and make the constant improvement accordingly.
Looking ahead, which emerging technologies or trends do you believe will most unlock new levels of efficiency in your field?
C.C: Emerging technologies such as modular connection systems and advanced FEM-based structural optimization will significantly enhance installation speed and overall structural reliability. In addition, digital design tools—including AI-assisted structural optimization (covering the design refinement of fasteners and connection components) and microclimate modeling for agrivoltaics—will further shorten development cycles and improve overall system efficiency.
Your mounting bracket is made of galvanized steel, would it be too heavy compare with aluminum one for the concrete roof top of the building?
C.C: Many of our clients have this wrong conception in the beginning. To be resistant from the wind stroke or storm, the whole installation must reach certain weight. Using the steel structure can reduce the use of concrete ballast, while the lighter structure made of other material will need to increase the weight of concrete ballast. In the end the total weight is the same, but using the steel structure can reduce the cost for concrete ballast.
