Solar Consulting and Feasibility Studies
Terra MW provides independent solar consulting for commercial, industrial, and utility-scale projects. We've delivered over 1 GW of detailed engineering and technical consultancy across global portfolios. Consulting engagements establish project viability, financial returns, and technical requirements before capital commitment.
Clients use our feasibility reports for internal approvals, financing discussions, tender preparation, and EPC contractor evaluation. We work with industrial facilities evaluating energy cost reduction, utility developers planning multi-megawatt systems, and institutional buyers pursuing sustainability targets.
Typical turnaround is 3 to 7 days. Output includes site assessment, energy yield projections, financial modeling, risk evaluation, and scope definition for engineering or EPC phases.
Consulting Scope
Site Feasibility Assessment
We evaluate site suitability for solar installations through remote analysis and field surveys when required. Assessment includes roof structural capacity for rooftop systems, land topology and shading analysis for ground mount projects, grid proximity and interconnection feasibility, and space availability for target system capacity.
Site assessment identifies constraints early. This prevents engineering delays or cost escalation during execution phases.
Load Profiling and Tariff Analysis
We analyze consumption patterns from utility bills or metering data to size solar systems for optimal generation-to-load matching. Load profiling identifies peak demand periods, base load consumption, seasonal variations, and export potential for net metering or feed-in tariff scenarios.
Tariff analysis evaluates current electricity costs, time-of-use rates, demand charges, and projected tariff escalation. This establishes baseline economics for ROI calculations.
PVsyst-Based Yield Simulation
Energy yield projections use PVsyst, the industry-standard software for bankable performance modeling. Simulations incorporate site-specific weather data, module specifications, inverter efficiency curves, shading losses, soiling factors, temperature coefficients, and system losses.
PVsyst reports provide monthly and annual energy generation projections. Banks and investors require PVsyst analysis for project financing and performance guarantee validation.
System Sizing and Technology Recommendation
We recommend system capacity based on available space, budget constraints, load requirements, and grid interconnection limits. Technology recommendations cover module type selection (monocrystalline, bifacial, thin-film), inverter architecture (string, central, hybrid), mounting structure type (fixed tilt, tracking, elevated), and balance-of-system components.
Recommendations prioritize long-term performance, maintenance requirements, and technology proven in similar climatic conditions.
CAPEX and OPEX Modeling
Capital expenditure modeling includes equipment costs, installation labor, civil and electrical work, grid interconnection fees, regulatory approval costs, and project contingency. We provide cost breakdowns per watt or per megawatt based on current market rates for tier-1 equipment.
Operating expenditure projections cover preventive maintenance, cleaning schedules, inverter replacement reserves, insurance, monitoring system subscriptions, and performance degradation over 25-year system life.
ROI and Payback Analysis
Financial modeling calculates return on investment, simple payback period, discounted cash flow, net present value, and internal rate of return. Analysis accounts for electricity cost savings, depreciation benefits, carbon credit potential where applicable, and residual system value.
We model multiple scenarios including conservative, base case, and optimistic projections. Sensitivity analysis shows impact of tariff escalation rates, system degradation, and financing costs on project returns.
Risk Assessment and Mitigation Planning
We identify technical, financial, regulatory, and operational risks. Technical risks include shading changes from future construction, roof structural adequacy, grid stability, and equipment warranty enforcement. Financial risks include tariff regulation changes, subsidy withdrawal, and financing terms. Regulatory risks cover approval delays, interconnection policy changes, and compliance requirements.
Mitigation strategies are provided for each identified risk. This supports decision-making and contingency planning.
Project Scope Definition for Tendering
Consulting output includes detailed scope documents suitable for EPC contractor tendering. Scope definition covers system capacity and layout, equipment specifications, installation standards, testing and commissioning requirements, documentation deliverables, warranty terms, and payment milestones.
Clear scope definition reduces bid variations and enables accurate contractor comparison during tender evaluation.
Who Engages Consulting Services
Industrial Facilities: Textile manufacturers, chemical plants, warehouses, and food processing units evaluating rooftop or ground mount solar to reduce energy costs. Projects typically range from 500 kW to 10 MW.
Utility Developers: Project developers planning utility-scale systems from 10 MW to 100 MW and beyond. Consulting supports land acquisition decisions, grid interconnection planning, and financing discussions.
Commercial Enterprises: Shopping complexes, office parks, hotels, and logistics centers assessing solar feasibility for sustainability reporting and operational cost reduction.
Institutional Buyers: Hospitals, universities, and government facilities pursuing solar under energy efficiency mandates or sustainability targets.
Financial Institutions: Banks and investors conducting technical due diligence on solar projects before financing approval. We provide independent feasibility validation and performance assessment.
Consulting Deliverables
Standard consulting engagement delivers a comprehensive feasibility report including executive summary with key findings and recommendations, site assessment with aerial imagery or site photographs, energy yield analysis with monthly generation projections, system design overview with single line diagram, equipment specifications for tier-1 modules and inverters, financial model with ROI and payback calculations, risk assessment matrix, and project implementation timeline.
Reports are formatted for boardroom presentation or investor review. Technical appendices include PVsyst simulation results, load profile analysis, and compliance checklist for local regulations.
Why Independent Consulting Matters
EPC contractors often provide free feasibility studies bundled with execution proposals. These studies may overestimate returns to secure contracts. Independent consulting provides unbiased assessment without execution commitments.
Our consulting clients use feasibility reports to evaluate multiple EPC bids, negotiate better pricing, identify scope gaps, and establish performance benchmarks. This reduces execution risk and improves project outcomes.
We've provided independent consulting for clients in Denmark, Sweden, Bahrain, Australia, Kenya, and India. Projects range from 1 MW industrial rooftops to 60 MW utility-scale systems.
Consulting Process
Initial inquiry includes project location, site type (rooftop or ground mount), available space, annual electricity consumption, current tariff rates, and target system capacity if known. We respond within 24 to 48 hours with engagement terms.
Data collection phase requires utility bills (12 months minimum), site photographs or drawings, roof structural drawings for rooftop projects, and land survey for ground mount systems. Remote assessment is completed first. Site visits are scheduled if structural verification or detailed shading analysis is required.
Draft report is delivered in 3 to 7 days. Final report incorporates client feedback and clarifications. Consulting fees are typically structured as fixed price per megawatt or hourly rates for extended advisory engagements.
Consulting Tools and Standards
We use PVsyst 7.4 for energy modeling, Helioscope for layout optimization and shading analysis, Google Earth Pro and drone imagery for remote site assessment, AutoCAD for preliminary system layouts, and financial modeling templates aligned with IFC and World Bank project appraisal standards.
Feasibility reports reference IEC 61724 for performance monitoring, IEC 61215 for module qualification, IEC 62446 for grid-connected system installation, and local standards (MNRE in India, AS/NZS 5033 in Australia, BS 7671 in Middle East, European Low Voltage Directive in Europe).
