Electrical energy storage systems
Solar Spektar AG, as an EPC company (Engineering • Procurement • Construction), is focused on the development and implementation of Battery Energy Storage Systems (BESS) integrated into photovoltaic (PV) power plants. Our approach is fully engineering-driven—based on precise modelling of energy flows, compliance with grid requirements, and optimization of economic performance—delivering a complete turnkey solution.
An integrated BESS transforms a PV plant from a passive generator into a flexible energy resource. Through intelligent control via an Energy Management System (EMS), the system enables retaining and strategically utilizing surplus energy, reducing peak demand, improving power quality, and controlling active and reactive power in accordance with grid connection requirements. The result is higher investment efficiency, improved predictability of production, and more effective integration into the power grid.
As an EPC partner, Solar Spektar AG provides a comprehensive service across all project phases:
- Concept development, sizing and techno-economic modelling (power/energy capacity, operating strategy, revenue and savings scenarios, risk analysis)
- Basic and detailed engineering design (single-line diagrams, protection and selectivity, calculations, cabling, grounding, communication architectures, SCADA integration)
- Procurement and logistics of key equipment (battery modules/containers, PCS, transformers, MV/LV equipment, metering and protection devices, communication components)
- Construction, system integration and commissioning (FAT/SAT, functional and performance testing, EMS parameterization, export control/limitation, calibration of measurement points)
- Operational support and O&M (remote monitoring, preventive maintenance, performance optimization and reporting)
Our goal is to deliver BESS solutions that are technically robust, regulatory-compliant, and financially optimized, with clearly defined guarantees for functionality, safety, and performance. With Solar Spektar AG, your PV plant becomes more flexible, more resilient to grid constraints, and ready for new market mechanisms—where value lies not only in the energy produced, but in the ability to manage that energy intelligently.
