Company history

Solarsenal LLC, an Axalton Group company, was established in 2019 to take over the energy-related projects from another entity in the group, BSS Unit Inc, which focuses on providing operational resilience and security, cybersecurity services to critical infrastructure.

The Axalton Group is a Private Asset Management Firm, based in Washington DC, focusing on specific industries, with growth equity, investing its own capital in companies that have strong growth potential, that are expanding into new markets or introducing new products or services. Axalton principals and member companies have a history of providing services to the military (NATO), law enforcement, homeland security, and are engaged in the protection of critical infrastructure in Europe and North America. Axalton companies include Cyber Arsenal, Green Arsenal, Clean Arsenal and Hemp Arsenal.

Solarsenal’s predecessors, BSS Unit Inc, and PSI Europe, have been responsible to maintain business continuity and perform resilience audits for critical infrastructure, namely gas storage facilities, power stations, and infrastructure of the leading energy companies in Europe (Alpiq, E.on, Engie) for the last 25 years. The founders recognized the urgent need for renewable energy solutions and expanded the group’s portfolio with energy generation and storage technologies. Solarsenal was formed as an integrator company to provide at first software-based energy management (EMS) and industrial security services, and later full integrated energy solutions in the United States


In the years leading up to the Inflation Reduction Act (IRA), signed into law on August 16, 2022, Solarsenal’s primary focus was designing rooftop solar and energy storage systems for commercial buildings in Washington DC. Traded Solar Renewable Energy Credits (SRECs) are the most valuable in the District of Columbia, which has the least real estate for solar development among all the states, hence the rooftop development. Income & savings benefits for the clients included an attractive ROI, reduction of peak charges, and the ability to add revenue generating services like EV charging to the bottom line. The business model positioned SPVs as asset owners in order to fully utilize the 26% IRS commercial investment tax credit (ITC) and the 100% accelerated & bonus depreciation, creating an exceptional incentive for investors to buy.

After the IRA, which increased and extended the renewable energy incentives to battery energy storage systems, more opportunities opened up both in the residential, commercial, as well as utility-scale markets for Solarsenal. Companies operating heavy Industrial facilities on several sites have requested Solarsenal’s expertise in designing integrated renewable energy and backup systems tailored to their needs for accommodating peak usage as well as grid-independence. Community storage (200 kWh – 1 MWh) for townhouses and new developments, especially when coupled with solar generation, proves to be a more efficient use of the infrastructure than individual energy storage units. Solarsenal is also currently positioning its 15-90 kWh SMARTESTORAGE energy storage units on the approved vendor list of financing companies for the residential market.

Over the years, our company has grown and evolved, but our commitment to sustainability and innovation has remained constant.

As we continued to grow, we expanded our focus to include non-industrial critical infrastructure, such as hospitals, data centers, and government buildings. Our team of engineers and technicians have worked closely with clients to design and implement customized renewable energy solutions that meet their unique needs and requirements.

Today, our company is recognized as an authority in the renewable energy industry, with a reputation for delivering high-quality, innovative, and cost-effective solutions. We continue to push the boundaries of what is possible in renewable energy integration, and we are committed to helping businesses and communities achieve a more sustainable future.

The Solarsenal team is proud to have worked on a diverse portfolio of projects that have brought sustainable, efficient, and energy-independent solutions to industrial facilities and critical infrastructure worldwide. Our portfolio includes:


Successfully delivered over 120 MW of PV and battery storage integration for clients on four continents: North America, Europe, Asia, and Africa since 2004.

Engineering and manufacturing expertise goes back to the early dawn of commercial PV research in the 1990’s. With 100 years of cumulative EPC team experience, work included project development, construction management, operation services, full service EPC, experience with string inverters, central inverters, crystalline modules, thin film (amorphous silicon, CdTe), fixed angle devices, solar trackers, as well as battery storage and wind turbines. We have made improvements to construction processes in order to increase installation speed, reduce labor costs and environmental impact, and maximize solar energy output through the entire lifecycle of solar projects.

Proprietary design & engineering research: Horizontal Single-Axis PV Tracking System which can achieve 19-25% more yield than traditional photovoltaic systems (yield increases closer to the equator) as well as development, prototype building and testing of a new run-of-river hydro turbine, a dual-axis solar tracker, HCPV (High Concentration PhotoVoltaic ) module development high-efficiency non-flammable high-voltage rugged battery energy storage systems and a patented vertical axis wind turbine.

Regarding our VERTICAWIND wind turbines there has not been any repair requirement in any working system deployed on four continents in the last 15 years.


Low voltage (under 150kWh capacity) energy storage systems using the latest SMARTESTORAGE technology have been deployed in California, the Caribbean, South Africa, Indonesia, and Hungary to provide off-grid solutions for commercial entities including an air field, industrial locations, and residences with extensive energy use.

Utility-scale development of SMARTESTORAGE began with a 500 kWh system installed in a 20-ft shipping container in Europe, which included 390 400Ah LFP cells, connected to a VERTICAWIND wind turbine, solar arrays, and an EV charger (Specs: 250 kW inverter, 690V output voltage, 80 kW transformer to achieve 3x230V at 50 Hz, the three AC phases, as well as 820V charging voltage through direct DC connection from solar panels). Years of successful testing for energy efficiency, self-discharge, environmental resilience, charge/discharge cycles, and maintained power output, by major utility providers in Europe resulted in orders being placed for utility-scale projects.

One popular battery cell technology used by SMARTESTORAGE has been installed at the University of California, and in energy storage cabinets, container trucks, school buses, and concept cars throughout the United States. Walmart installed the technology for refrigeration in a tropical Asian country. The premium batteries are also used in military submarines.


Each of these areas of development represents our commitment to delivering high-quality, innovative, and customized solutions that meet the unique needs and requirements of our clients. We are proud of our portfolio and the impact that these projects have had on our clients’ operations and the environment.
