Solar Advisory Services
Accelerating solar adoption through strategic advisory and technical excellence
OUR VISION
Why Choose us
We deliver end-to-end strategic support to accelerate solar deployment with technical rigour and financial clarity. We enable clients to navigate feasibility, design optimisation, regulatory compliance, and execution oversight with a data-driven, bankable approach. Our expertise ensures reliable project outcomes, mitigated risks, and long-term asset performance across diverse solar applications.
Feasibility Studies & DPRs
Our team conducts detailed site assessments, energy yield analysis, and techno-commercial feasibility to ensure every project is bankable and optimised.
Solar Design & Engineering
We deliver electrical, structural, and civil designs for rooftop, ground-mounted, and floating solar systems, aligned with IEC and CEA standards.
Owner’s Engineering & PMC
Acting as your technical representative, we oversee project execution, quality assurance, and commissioning — ensuring performance.
Tariff & Regulatory Advisory
We support developers, DISCOMs, and regulators in tariff benchmarking, power purchase agreements, and open-access policy development.
Performance Audits
Our performance audits identify technical bottlenecks, ensure efficient operation, and maximise solar generation throughout the asset life cycle.
Hybrid & Floating Solar
Combining hydro and solar expertise, we design floating and hybrid solar systems to enhance generation while optimising land and water use.
Comprehensive Solar Consulting Services
For over 15 years, Firstgreen Consulting has led the renewable energy transition through data-driven and technically sound solar advisory. We support corporates, developers, and governments in planning, designing, and implementing solar projects that maximise generation, optimise capital investment, and ensure regulatory compliance.
Our services span the full project lifecycle — from initial feasibility to post-commissioning performance audits. With a portfolio exceeding 1 GW of solar projects across India, Bhutan, Nepal, and Africa, we bring unparalleled expertise in engineering, economics, and sustainability.
