What does Suntomine do?
Suntomine is an integrated energy solutions company and a full-service EPC and turnkey provider, specializing in solar PV systems, ground-mounted racking structures, and battery energy storage solutions. We deliver end-to-end projects from engineering and manufacturing to commissioning.
Where is Suntomine based and where does it operate?
Suntomine’s headquarters and main manufacturing operations are located in Brčko District, Bosnia and Herzegovina. The company is expanding operations into Serbia and is currently in the process of establishing a representative office in the United States to support international projects.
What makes Suntomine different from typical solar companies?
Suntomine’s integrated approach—combining in-house manufacturing, EPC execution, and system-level engineering—is closely aligned with energy-intensive applications such as crypto mining and data centers. This enables us to deliver reliable, high-uptime energy infrastructure for continuous-load operations.
What types of projects does Suntomine deliver?
Suntomine delivers commercial, utility-scale, and off-grid solar projects, including complex, energy-intensive installations and remote infrastructure. Our turnkey model ensures seamless execution across all project phases.
Who does Suntomine work with?
We work with developers, utilities, EPC partners, industrial clients, crypto data center operators, and all organizations interested in adopting solar energy solutions. Our focus is on long-term partnerships and dependable clean energy delivery.
Why choose HJT technology for utility-scale projects?
HJT (Heterojunction) technology delivers higher efficiency and superior energy yield, especially in hot and low-light conditions. With module efficiency up to 24.1%, it enables more power per square meter and stronger project economics.
How do these modules perform over time?
The modules feature extremely low degradation, with less than 1% in the first year and only 0.375% annually thereafter. This ensures at least 88% power output after 30 years, supported by a 30-year linear power warranty.
Are the modules suitable for harsh weather conditions?
Yes. The double-glass bifacial design and anodized aluminum frame provide high resistance to wind, snow, humidity, and temperature extremes. The modules are mechanically rated up to 5400 Pa snow load and certified for demanding outdoor environments.
How do bifacial modules increase energy yield?
With bifaciality of up to 90%, the modules generate additional power from reflected light on the rear side. This makes them particularly effective for ground-mounted and utility-scale installations with optimized site surfaces.
Are these modules easy and safe to install on large sites?
The modules are designed for professional utility-scale installation, with standardized mounting points, UL and IEC certifications, and clear handling and installation guidelines. Vertical packaging and defined unpacking procedures support safe, efficient logistics on large projects.
What applications is this energy storage system designed for?
Our BESS supports grid-tied, off-grid, and hybrid applications, making it ideal for solar + storage, peak shaving, backup power, and microgrids. The system features advanced thermal management designed to ensure stable, efficient operation across a wide range of environmental conditions.
Why is liquid cooling a key advantage of this BESS?
Liquid cooling maintains extremely stable cell temperatures, with differences of less than 3 °C across the battery packs. This extends battery lifespan, improves efficiency, and ensures reliable performance even in high-temperature environments.
How safe is the system for long-term operation?
Safety is ensured through LiFePO₄ battery chemistry, an intelligent BMS, continuous monitoring, gas detection, ventilation, and integrated aerosol fire suppression. These layered protections enable secure and reliable long-term operation.
Is the system suitable for outdoor and harsh environments?
Yes. The system is designed for outdoor installation with a robust enclosure, corrosion protection, and a wide operating temperature range from –30 °C to +60 °C. This makes it suitable for diverse climates and demanding site conditions.
How easy is installation and commissioning?
The BESS is delivered as a pre-integrated, turnkey solution with clear installation and commissioning procedures. This minimizes on-site work, shortens project timelines, and simplifies deployment for EPCs and developers.
What products are manufactured in-house?
We manufacture solar racking systems and key BESS components in-house. This integrated production approach ensures consistent quality, technical compatibility, and reliable performance across energy storage and PV support structures.
Where is the manufacturing facility located?
Our production facility is located in Brčko District, Bosnia and Herzegovina, a strategically positioned manufacturing hub with strong industrial infrastructure and efficient access to European and global markets.
How does in-house manufacturing benefit project delivery?
In-house production reduces supply chain risks, shortens lead times, and enables predictable delivery schedules. This allows EPCs and developers to plan and execute projects with greater confidence.
How is quality ensured during production?
All products are manufactured under controlled processes with multi-stage quality inspections. From material selection to final assembly, production is aligned with relevant international quality and safety standards.
Can products be customized for specific projects?
Yes. Our manufacturing capabilities support project-specific customization of racking systems and BESS components, allowing solutions to be adapted to site conditions, system layouts, and project requirements.
What type of projects have been successfully completed?
We have successfully delivered an off-grid solar project in Tonopah, Nevada (USA) with a total nominal capacity of 1.7 MW, developed to supply power to a remote data center for crypto mining operations. The project serves as a strong reference for energy-intensive, off-grid applications.
What does the Tonopah project demonstrate?
The project demonstrates stable and reliable system operation under high-temperature, high-irradiance desert conditions, confirming the durability and performance of the installed solar infrastructure.
What technical solutions are validated through completed projects?
Completed projects validate the performance of ground-mounted racking systems, PV modules, and balance-of-system components under continuous, high-load operating conditions.
How do completed projects reduce technical and delivery risk?
Field-proven designs and installation practices reduce engineering risk and enable predictable performance and delivery timelines for future projects.
How are lessons learned from completed projects applied to new systems?
Operational feedback and performance data from completed projects are continuously incorporated into system design and manufacturing processes, ensuring ongoing improvement and reliability.
