About RSNKP
Swiss Engineering with International Project Experience
For more than 23 years, RSNKP has been active in photovoltaics, renewable energy and the technical
development of complex energy projects. We combine engineering, project development, financial
feasibility, financing support, permitting coordination, procurement, construction supervision,
quality assurance, commissioning and long-term project support.
RSNKP is not a conventional installation company and not merely an equipment supplier. We act as
the independent engineering and project development partner between investors, developers,
manufacturers, EPC contractors, banks, authorities, utilities and grid operators. Our objective is to
develop projects that are technically reliable, commercially viable and professionally prepared for
international financing processes.

Vision
Our vision is to create renewable energy projects that combine engineering excellence, commercial
viability and long-term sustainability. We aim to deliver infrastructure that gives investors
confidence, operators reliability and communities lasting value.

Mission
Our mission is to support clients throughout the complete project lifecycle with independent
engineering, robust decision-making documentation and consistent quality assurance - from the first
concept to safe and reliable operation.

Our Experience
Our experience includes commercial photovoltaic systems, industrial installations, ground-mounted
plants, utility-scale solar parks, PV projects from 3 MWp to more than 100 MWp, battery energy
storage systems, hybrid power plants, microgrids, medium- and high-voltage systems, grid
connection and energy infrastructure projects. Every project is adapted to local technical,
commercial and regulatory requirements.

Our Services
Project Development
We support energy projects from the initial concept to investment and construction readiness.
Services include project definition, site assessment, land analysis, preliminary grid review, project
structuring, technical feasibility studies, energy yield forecasts, investment assessment, risk analysis,
development planning, project schedules and support for PPA and contractual structures.
Feasibility Studies
A professional feasibility study is the foundation of every sound investment decision. We evaluate
solar irradiation, available land, topography, soil conditions, shading, grid connection, system
configuration, expected energy yield, technical losses, CAPEX, OPEX, project lifetime, risks,
permitting requirements and financial indicators. The result is a transparent decision-making basis
for developers, investors and financing partners.

Photovoltaic Engineering
RSNKP develops complete technical concepts for PV plants of different sizes. Our scope includes
module layout, land optimization, system configuration, string design, DC and AC engineering,
inverter sizing, cable sizing, voltage-drop calculations, mounting structures, foundation concepts,
transformer stations, medium- and high-voltage connections, grounding, lightning protection,
protection systems, SCADA, monitoring and communication systems.

DC and AC Engineering
Optimized electrical design is essential for energy yield, safety and economics. RSNKP provides DC
string configuration, module and string design, inverter sizing, DC and AC cable routing, cable cross-
section and loss calculations, collection systems, transformer sizing, medium-voltage engineering,
protection concepts, grid connection engineering, single-line diagrams, cable schedules and
equipment lists.

Mechanical, Structural and Civil Engineering
Our services include fixed-tilt and tracker systems, pile and foundation concepts, wind- and snow-
load calculations, seismic assessment, corrosion protection, material selection, terrain adaptation,
access roads, drainage, construction logistics and installation concepts. The objective is a durable,
safe and maintainable asset.

Battery Energy Storage Systems
RSNKP develops and integrates BESS solutions for load shifting, peak shaving, grid services,
frequency regulation, grid stabilization, energy trading, self-consumption optimization, backup
power, island operation, black start and renewable energy smoothing. Our scope includes capacity
sizing, technology selection, container concepts, BMS, EMS, PCS, transformer integration, HVAC, fire
protection, safety systems, monitoring, SCADA, operating strategy and technical documentation.

Grid Connection and High Voltage
We plan the electrical connection from the solar field through inverters, transformers and medium-
voltage systems to the grid connection point. Services include grid connection concepts, MV/HV
systems, transformer stations, switchgear, protection engineering, relay concepts, grounding,
lightning protection, grid studies, load-flow, short-circuit, voltage and frequency analysis and
technical coordination with grid operators.

Financial Feasibility and Financing
RSNKP combines engineering with commercial responsibility. We prepare CAPEX and OPEX models,
energy yield models, cash-flow forecasts, ROI, IRR, NPV and LCOE analysis, payback calculations,
sensitivity and scenario analysis, debt and equity structures, vendor-financing concepts, PPA-based
business models and bank and investor presentations.

Bankable Project Documentation
We prepare executive summaries, technical project descriptions, feasibility studies, energy yield
analyses, CAPEX/OPEX overviews, cash-flow charts, financing structures, project schedules, risk
matrices, permitting overviews, procurement strategies and construction and commissioning
concepts. The final credit decision always remains with the respective financial institution.

Permitting and Regulatory Support
RSNKP supports building permits, environmental approvals, grid connection and feed-in
applications, energy authority requirements, fire safety, land-use requirements, import and export
documentation, product certificates, technical compliance evidence, insurance requirements and
PPA-related documentation. We coordinate with local partners, authorities, engineering specialists
