Solar Consultancy and Technical Advisory

Solar consultancy gives an owner independent technical clarity before committing capital — what capacity is feasible, what it should cost, what specification to insist on and what to verify during execution.

Solar consultancy gives an owner independent technical clarity before committing capital — what capacity is feasible, what it should cost, what specification to insist on and what to verify during execution.

Overview

Many solar disputes trace back to decisions made before installation: optimistic capacity assumptions, structures not designed for site wind loading, undersized cables or specifications loose enough to permit substitution.

GLS offers advisory work covering feasibility, sizing, specification drafting, proposal comparison, design review and execution-stage inspection, so that technical decisions are made on evidence.

Who it is for

  • Businesses evaluating a first solar investment
  • Project owners comparing multiple EPC proposals
  • Institutions needing a defensible technical specification
  • Owners wanting independent review of a running project

How it works

Feasibility

Site, structural, shading and electrical review against your consumption and objective.

Specification

Technical requirements written so that offers are comparable and substitution is controlled.

Evaluation

Proposal comparison on specification, scope completeness and realistic generation assumptions.

Oversight

Stage inspection during execution and verification at commissioning.

Key benefits

  • Decisions grounded in site data, not sales claims
  • Comparable, clearly scoped vendor proposals
  • Fewer design-stage errors carried into construction
  • Independent verification at commissioning

Technical considerations

Generation estimates
Indicative generation is stated with its assumptions — irradiance source, performance ratio, soiling and degradation — not as a guarantee.
Document review
SLDs, structural calculations, cable sizing, protection coordination and test reports are reviewed against the design basis.

Process

  1. 01 — Consultation

    We understand your load profile, electricity bill, tariff category and objective.

  2. 02 — Site Assessment

    Roof or land survey covering area, orientation, shadow, structure and electrical infrastructure.

  3. 03 — System Design

    Capacity sizing, layout, module and inverter selection, cable and protection design.

  4. 04 — Proposal & Planning

    Detailed scope, bill of materials, indicative generation and commercial proposal.

  5. 05 — Engineering & Installation

    Structure fabrication and erection, module mounting, DC and AC works, earthing and protection.

  6. 06 — Testing & Commissioning

    Insulation, polarity, string current, earthing and inverter commissioning checks.

  7. 07 — Grid Integration / Handover

    Coordination for net-metering or grid approval where applicable, then documented handover.

  8. 08 — Monitoring & O&M

    Generation review, scheduled cleaning and inspection, and corrective maintenance.

Components we use

Project examples

GLS has completed 300+ projects across Tamil Nadu. Case studies in this category are being documented with client approval, and we publish only what owners have confirmed may be shared. Ask us for references relevant to your category and we will send what has been approved for disclosure.

Frequently asked questions

  • Can I use consultancy without awarding GLS the installation?

    Yes. Advisory work can be engaged on its own, and many owners do exactly that to keep the review independent of the execution contract.
