Who we are
An engineering and advisory company for green energy, critical infrastructure and investment clarity.
Solar Green Defence operates at the intersection of energy engineering, investment structuring and technical risk management. Our role is to guide complex energy projects through their real dependencies: land rights, planning feasibility, resource, technology selection, grid connection, permitting, construction, commissioning, operational reliability and financial outcome.
01
Approach aligned with energy legislation, renewable energy regulation, spatial planning rules, grid connection procedures and environmental regimes
02
Technical solutions compared by yield, capacity, operating mode, losses, safety, maintenance and lifecycle performance
03
Advisory support for investors, landowners, industrial consumers, project companies and financing partners
Core domains
Energy capabilities organized around the actual project lifecycle.
We do not view a project only as installed capacity. We assess the full chain: resource, location, grid, legal status, technologies, construction, market realization, operation and exit strategy.
Photovoltaic power plants
Pre-investment assessments, layout concepts, module and inverter selection, yield expectations, DC/AC ratio, grid constraints, technical specifications and delivery control.
Wind energy projects
Wind resource review, micrositing, infrastructure access, land and environmental constraints, preliminary techno-economic framework and coordination with specialist designers.
Hydropower solutions
Advisory support for small and medium hydro projects, water resource review, hydraulic dependencies, permits, environmental constraints and technical compatibility.
Battery energy storage systems
BESS sizing, technology selection, EMS/SCADA logic, fire and electrical safety, grid connection, cycling, degradation and revenue scenarios.
Gas-steam installations
Expertise in combined cycles, gas turbines, heat recovery steam generators, steam cycles, energy efficiency, reliability and integration with industrial or system load.
Design and engineering
Design briefs, discipline coordination, technical specifications, bills of quantities, project documentation review and preparation for permitting procedures.
Investment advisory
Assessment of project ideas, market logic, contractual framework, PPA opportunities, guarantees of origin, balancing, CAPEX/OPEX, sensitivities and deal structuring.
Technical due diligence
Independent review of land, rights, permitting status, design documentation, technology offers, grid connection, contracts, risks and financing readiness.
Why choose us
Energy projects usually fail because of missed dependencies, not because of a lack of ambition.
We work systematically when technical expertise, regulatory discipline, financial logic and execution control have to be connected. This is especially important for RES and battery assets, where a wrong early assumption can block grid connection, permitting or project economics.
01
Validation before commitment
Before major investment decisions are made, we clarify critical assumptions: land, constraints, grid, resource, ownership, timing, permitting risk and market model.
02
Technical language for investors
We translate design, energy and construction parameters into management decisions so the client understands what is being purchased, what risk is accepted and what must be controlled.
03
Control across the process
We maintain continuity from concept and specification through contractor selection, contract review, construction, acceptance, operation and subsequent optimization.
Technical framework
Capability covering generation, storage and energy management.
We approach every project as a system of connected engineering, legal and economic decisions. This reduces uncertainty in grid connection, technology selection, construction, operation and financial modelling.
PV, wind, hydro and hybrid RES projects with resource, configuration, grid and yield analysis
Battery storage, EMS/SCADA, protection systems, fire safety, degradation and operating scenarios
Gas-steam installations, combined cycles, energy efficiency, reliability and integration with system or industrial loads
Due diligence, investment memoranda, technical specifications, tenders, contract frameworks and owner engineering
Trust and responsibility
Work based on documented logic, traceability and professional discretion.
Energy investments often involve sensitive data about land, contracts, financing, grid statements, commercial negotiations and technology offers. We therefore maintain structured communication, clear assumptions and written outputs that can be used in management, technical and financing processes.
Clear definition of scope, source data, constraints, assumptions and responsibilities
Reporting focused on risk, consequences, dependencies, options and recommended next actions
Confidentiality in transactions, project assets, due diligence, partnerships and investment negotiations
Next step
If you have land, a project idea, an asset to acquire or a need for independent technical review, we can begin with a focused conversation.
The first step is to clarify the project type, available documents, client objective and critical unknowns. We can then propose a scope for analysis, engineering brief, due diligence or delivery support.
Contact
Discuss your next energy initiative with a partner who thinks technically, regulatorily and commercially.
Send an inquiry related to PV, wind, hydro, battery storage, gas-steam installations, grid connection, technical due diligence, investment advisory or delivery control.
